• LOST or CORRUPT VMFS (data store)

  Hello

  strange symptoms, when saving comments via the network on the NAS Server freeze.

  No disk error, allow to manage but no o off not restart guest system.

  Restart Vmware (4.0.0 261974 on HP DL380G4 - Smart Array 6i) and Datastore disappeared!

  No errors on the disc,

  2 disk raid 6i, a RAID 1 OK (36 GB X 2) a RAID 5 (146 X 3) ok ok but this data store is gone!

  On the storage card, I see 'Vmware disk Local (mpx.vmhba1:C0:T1:L0) but no data store '.

  No vmfs or another partition...

  I try this solution:

  -Rescan store, but not reassign datastore

  -Rescan with change EnableResignature and disable DiallowSnapshotLun.

  A lot of help via the forum vmware or google:

  and many other, but no solution.

  in/dev/disks I see

  MPX.vmhba1:C0:T1:l0

  But if fdisk /dev/disks/mpx.vmhba1:C0:T1:L0 answer me

  Fdisk: can't read /dev/disks/mpx.vmhba1:C0:T1:L0

  I'm trying to suggest to the KB 1009829 and esxcfg-scsidevs - c see my unrecognized store

  but fdisk my same error response:

  Fdisk: can't read /dev/disks/mpx.vmhba1:C0:T1:L0

  If I try /dev/disks/mpx.vmhba1 response is

  Fdisk: cannot open of /dev/disks/mpx.vmhba1

  I guess that the syntax is correct, because if I put another store (C0:T0:L0) I get the correct message

  fdisk-l don't see C0:T1:L0

  in other KB (1008886) suggest me to use parted, but console vmware 4 do not have this command! I tried partedUtil and I see this:

  partedUtil get /dev/disks/mpx.vmhba1:C0:T1:L0

  35697 255 63 573480304

  What is - this? change this? which?

  I have download parted (gnu) but everything installed try I get "configure: Permission denied ' suggest?

  I try KB (1009565)

  and I get this:

  Please help with suggest another way...

  Thank you!

  There is a road to try to recover partition?

  That's why I suggested to run the ACU. To check the controller has all the problems and presents the logical volume properly to the operating system.

• Stores the data corrupted of VMFS - how causes?

  Hi all

  We run Lab Manager 4, so we still have ESXi 4.1 hosts in our infrastructure that we cannot upgrade to ESXi 5.x.

  In one of our sites, we regularly see corruption VMFS, where some virtual computer files can not be read/deleted/listed.  We are trying to add new storage and migrate our current VMs out of corrupted data stores, but I would like to know what is originally this corruption and how do I stop him from happening in the future?

  Hosts: HP DL360p G7

  Storage: HP P2000 G3

  ESXi: 4.1.0 build-260247

  If we see a lot of such errors, once restart us all hosts, the number decreases (for example 20 errors, we are left with only 3).

  Have you seen this topic on your site?

  Thank you

• Corrupted partition table

  Hello

  I have a bad experience on my virtual infrastructure.  I'm just applied ESX4 and connected to the Fujitsu SAN storage, I face the corrupt VMFS partition 2 times a week.  I have the call log to support and found that VMware part is no problem, and my storage vendor has also found that the storage is health.  I don't know what to do now, someone has this experience can give some advice?

  Thank you

  the Member of 4100 not showing this info, all connected to the 6100 Member?

  side esxi 5.5 its projection lost way, restoration of path error messages

  clues

  Hello Dan,.

  This first message is normal, because this is a message of level INFO, not WARN or ERROR.  It only means that a connection has been disconnected so that it can be moved to another port in the group.   I suspect that you run MEM?   Who's going to move, start, stop to need iSCSI sessions to hold the input/output symmetrical on the ports available on the berries.

  ESXi 5.x will always report any kind of connection as an error problem.  Even when he is projected as here.  EQL uses a mandatory iSCSI command under the title "async logout" say disconnect the iSCSI initiator then go to discovery and connect immediately.  However, this time it will be moved to another port on a table.   MEM regularly consults the current connections and may decide to change the layout of the connection.

  The 6100 is probably the head of the group.  So it stores and displays all messages from all members of the group.  Buried in the text it can show you that some are from the 4100.

  The other message on the "6 sec timeout" is different.  This means that, during this period, the table failed this server.  Periodically, initiator and Exchange EQL keep packages of persistent delay.  (KATO for short).   This is so that the two are always answer.  If it fails repeatedly, this message appears and the connection is complete.  Once the initiator (server) is back, he will open a new iSCSI session to replace.   You see this message when you restart a server, or there are problems with the network.

  If you are really interested, you can open a case of pension with Dell.  Please gather the diags table (all members), config switch logs, and supports the VM node ESXi.   They can check this info and verity that the configuration is OK.    They can examine the nodes ESXI to ensure they are in compliance with the best practices with Dell's best practices.   There is a Tech report.   TR1091 that covers this.

  You can find a copy here.

  en.Community.Dell.com/.../Download

  Many problems have been resolved by choosing ESXi for current construction, set up in accordance with this document and Sunrise switches to spec as well.

  Make sure also that the EQL table running 6.0.7 or later.  Running current firmware is much better.  Earlier than 6.0.7 saw potential for corruption VMFS Datastore.  Therefore, it is very important to keep up-to-date.

  Kind regards

• Question VMFS / corruption?

  Hello

  I'm having a problem with a file in my VMFS data store:

  / vmfs/volumes/51d6fc9e - 9 to 548661-4054-00301bbd0b99/OpenERP7 # ls-l

  -rwxrwxrwx 1 root root 2751508480 6 Jul 12:28 OpenERP7-000002 - delta.vmdk

  / vmfs/volumes/51d6fc9e - 9 to 548661-4054-00301bbd0b99/OpenERP7 # rm *.

  RM: cannot remove ' OpenERP7-000002 - delta.vmdk': no such file or directory

  Is not its good in my book (unless I'm missing something obvious here, that is always possible...). Although it does not affect my daily use if would be nice if I could retrieve these 20 GB and more important still to ensure that my data store in not corrupt.

  Any idea / suggestion more welcome!

  Try restarting the management on the ESXi host agents.

  from ssh console run below the DGM

  restart the /etc/init.d/hostd

  restart the /etc/init.d/vpxa

• Detach the corrupt empty VMFS datastore hosts (data store is an iSCSI LUN)

  Sorry people - can't all in fact it nails with a Google.

  I have a corrupted (size beyond 2 TB by accident) data store. Migrate all hosts out there - she is empty.

  As it is corrupt, it does not in the normal way.

  Now I CAN just tear out of the EqualLogic SAN - but I don't want to confuse ESXi.

  Can someone tell me how "friendly but firm" about ESXi to let go of it before I delete it the San?

  Thanks many many - Tim

  Like a little help, I have denied access of a host to the LUN and restarted mode maint.

  It is not in the view hosts of storage thereafter.

  If I repeat, it erases it completely from vCenter?

• VMFS partition table corruption? Need help to retrieve data

  My House ESXi 5.1 was installed on HP Microserver G7. Hypervisor on USB-flash, datastore on Adaptec 3405.

  After some problems of power electro Microserver is will not start and I have chosen to build the new server on Microserver Gen8. I moved Adaptec and disks in the new box, installed new ESXi 5.5 U1 (HP image) on USB and after reboot did not store data :-(.

  After some research, I found that ESXi is not see any partition table on this raid array:

  
  

  partedUtil getptbl /vmfs/devices/disks/mpx.vmhba2:C0:T0:L0

  unknown

  728422 255 63 11702108160

  BUT! I tried to start the server of linux liveCD with vmfs-tools 0.2.5 installed partition mounted with vmfs-fuse and able to see the data! But cannot copy all important vmdk (see below).

  debugvmfs is also show me some useful information:

  Volume Version: 14

  Version: 54

  Label: STORE

  UUID: 4f2ac538-58c181cf-arms-441ea13ee615

  Block size: 1 MiB

  Subblock size: 8 KiB

  Size of header of the FDC: 64 KiB

  County of FDC Bitmap: 64

  and it's very strange

  debugvmfs/dev/sda1 see the lvm.extent [0]

  NUM. Segments: 22319

  First Segment: 0

  Last Segment: 22318

  
  

  because I don't know that I don't create scopes.

  
  

  Also, there are two vmdk files on more than 256 GB data store and it cannot copy because of the limitation of vmdk-tools :-(.

  
  

  I tried to do a magic (like this - partedUtil setptbl "/ vmfs/devices/disks/mpx.vmhba2:C0:T0:L0" GPT "1 2048 11702099429 AA31E02A400F11DB9590000C2911D1B8 0""), but without success;-(.)

  
  

  All the suggestions, guys?
  

  Finally!

  Found that was an "Intel VT - d" enabled in the BIOS. After disable it everything is cool.

  It looks like Adaptec 3405 working wrong with it. Will try to change it to P222.

• Corruption in the VMFS data store

  Hi all

  I have a data store VMFS that has a directory that ESX doesn't happen to delete, even if it tries every 2 minutes.  The contents of the directory, it looks like something related to the directory index is damaged.  The directory looks like this:

  # ls-l 1020

  I can't delete all files with the?' s. I searched and could not find you check all sound tracks on a tool VMFS file system.  Some positions mentioned vmkfstools - R, but that option appear in my version (ESX 4).

  Can any thoughts on how I fix?

  Thank you

  Hello Jason,

  There is no fsck for vmfs. There is a 3rd third party tool which could for this in the future, but I wouldn't trust it now. See: http://planetvm.net/blog/?p=1592

  The best thing to do is get all your VMS out of this LUN, destroy the entirety of the LUN and recreate.

  Of course the most important is first of all to know what happened with your vmfs storage because it is very suspicious...

• VMFS5 data store shows several errors, which suggests the corruption of the file system?

• ISCSI dead and damaged VMFS partition metadata - cannot remove iSCSI

  Background:

  -1 Server vCenter

  -5 ESXi hosts connected to vCenter Server

  -2 (table 1 and table 2) iSCSI storage arrays

  We started getting errors in metadata corruption table-1 VMFS and migrated all storage table-2 VMS.

  The migration has been successful and virtual machines are operating normally.

  Directories and drives hard virtual VM have been removed from table-1 automatically by the migration.

  VM parameters see table-2 as the data store for all migrated virtual machines.

  HOWEVER - we're still showing 4 virtual machines under related objects-> VM on table-1 (we moved more than 20 virtual machines, and only 4 had this problem). It is the only reference I can find these table-1 and virtual machines. I think that it is somehow related to metadata VMFS corrupt. I completely disconnected table-1 of the network and virtual computers operate normally if clearly is not yet using table-1.

  THE PROBLEM - I can not remove the reference from table-1 my ESXi hosts iSCSI because they are 'in service' according to vCenter. I guess that's due to the incorrect references dangling these 4 virtual machines.

  How can I remove the table-1 data store and/or each ESXi host iSCSI device so that I can reformat and Add again as a new data store? I already deleted the dynamic/static under the iSCSI SW map entries. He presents himself as 'dead', but it will not disappear because of the error "in use."

  Thanks for any advice.

  Tracked down the problem finally.

  It was caused by a CD/DVD being mounted from the data store ISO on table-1 for these affected virtual machines. changing the setting to CD device Client rather than Datastore ISO for each referenced virtual fixed the problem computer, followed by a 'vmhba33 d esxcfg-rescan"since the ESXi console.

• Corrupt heartbeat not detected, no active contract

  Hi all

  I've been using the free ESXi 5, but after a stop force, I am facing the problem of corrupt heart beat of her now.

  According to the KB KB VMware: cannot access certain files on a VMFS datastore , should I post a request for assistance to resolve.

  But what do I do if I don't have an active member of the contract which I cannot file the request for assistance? Why the solution to this common problem is not documented?

  Thank you.

  > Why the solution to this common problem is not documented?

  very good question.
  I think it is because only a small number of the crew-support-VMware can treat this type of problems.

  Try to will the volume - which is often useful.
  If this is not the case - extract data-content with vmfs-fuse store

  If all fails I would like to take a look - you can call me through Skype "sanbarrow" but please wait on Saturday afternoon

• Corrupt VMs after power outage during the moved file

  Hi all, hope someone can help me here. I have a server ESXi 5 run here at home I play with. My Web server and some other vms for development are hosted here. Today, I bought a new hard drive of the server. I have all closed, open the folder, hooked up the reader. Booted back and made the new drive (2 TB), a data store. Then I went into the store of data browser for the old data store and clicked on each VM folder, and click the button "move to". I chose the new data store and copy. Naturally, he said it would take SEVERAL hours. I let it go. Well apparently I doesn't not hang all tight and while doing other work at the office, I struck the loose power and the system went down during the move. When I started back I couldn't use virtual machines. They have all said inaccessible!

  I tried to copy the files to the original location, but then esx complains that the vmdk is not a valid file. Is it possible to retrieve one of these virtual machines, or do I have to discard and start again? Please tell me there is a way to get back!

  I'm afraid there is not much you can do, except a call open with VMware to see if they have a chance or a tool to retrieve the Basic virtual disk file.

  In the log file, there are these two lines:

  2011 10-28 T 04: 01:31.886Z | VMX | DISKLIB-VMFS: VmfsExtentCommonOpen: as much as possible truncation (?) realSize is 1294136, descriptor size 1258291200.
  2011 10-28 T 04: 01:31.887Z | VMX | DISKLIB-VMFS: ' / vmfs/volumes/4e5c1292-e5c44add-2e76-000ffec5d18d/epitomeV/epitomeV-flat.vmdk ': cannot open (the specified file is not a virtual disk): measurement size in the file descriptor larger than actual size. Type 3

  which basically says the vmdk of base/flat has been corrupted. (For size of file in bytes, you must multiply the dimensions indicated with 512)

  Other VMware call, you could create a new virtual disk and restore your last backup data.

• People are leaning more towards VMFS or RDM these days? What YOU're running and why?

  Hello world

  I know there is a wealth of information on the subject and the standard response is to use both... whether you want array or snapshot level vm, etc..

  However, my environment is staged, I did some torture tests, tests of backup and restore. I'm almost ready to go wild p2v, but I'm still on the fence about the places where use RDM vs. VMFS. I'm running a cx500 and I was bitten by a flare code bug earlier that caused corruption unnoticed in my clone BCV we were using for backups - what was going on FOR the MONTH up to what we found out after we met weird with a cloned Oracle instance anomalies. From there I never did trust snaps or clones on the side of the table. On the other hand, I like the features of sleep to a vmdk.

  Looks like there are great benefits to go especially with VDR VMFS and similar tools push up. BUT... There is always this weird feeling relying on these vmdk files. Just curious to know what percentage of vs. VMFS, RDM people are running and why you personally and absolutely chosen RDM vs. vmfs.

  Thanks in advance.

  As we are ISCSI worldwide 3.5 we directly glued to the MSISCSI on virtual methods, it was for reasons of performance 3.5 with no MPIO

  4.0 worldwide we are leaning toward VMFS functionality set and the behavior of an interruption of SAN are advantageous for us and now with MPIO, we see large absolute performance of VMFS

• What expand a VMFS lun beyond 2 TB?

  Hello

  I need some opinions on what happens if you:

  • creates a LUN smaller than 2 TB (say, 1 TB)

  • built a VMFS on him and he put many VM

  • with the virtual machines running, go to the storage array and resizes the logical unit number, making it LARGER than 2 TB

  I know that this is not a smart thing to do and there is no reason to do it, but I want to understand what happens then a strictly tech point of view.

  For what I know about scsi, I guess that the vmfs will continue to work because there is no way to expand it to fill the new size, so he's going to stay within the limit of 2 TB and conntinue to work.

  But is it possible that growth triggers a few changes in the logical unit number so that esx will not longer be able to access the same first to 2, make the unreadable data and cause errors such as corruptions of metadata in the vmfs?

  I need a scsi on this expert opinion!

  Thank you very much for any info and opinions.

  Massi

  And no growth it will not damage your logic unit number. Personally, I don't see why you would want to passing. Creating a secondary LUN and loading with VMFS are much easier.
