All disks in a single host went from vSAN

Hello

I recently had a power cut at home. My 3 node cluster came back OK, but I noticed that the vSAN was missing lots of storage.

After investigation, it seems that all the disks in a single host have been abandoned (all 4 were operating before the incident).

I tried to reboot the host, but this has not solved the problems I encounter.

My file server is unable to turn on because of that, I think it was resynchronize components during the power failure happened.

Because I have data on these discs (my file server), I hesitate to re - install ESXi on the host or do something with the disks

I am due to upgrade my version of 3 disc format, but that he was reluctant to do this either at the present time because of my data!

Environment:

- vCenter Server Appliance 6.0 U2 (build 3634794)

-ESXi 6.0 Update 2 (build 3620759) on all hosts

Please can someone advise on the measures I should then carry out?

See below for information and some screenshots.

Thank you

Metadata health check informs me that the disks have failed, but all 4 disks functioned as expected before the power failure:

Research in the "Virtual SAN health status" column, it shows no health information on disks

Comparison to another host:

g8esxi3.png

The host CAN display the disks on it's HBA, see below:

Update:

Managed to find the size of the memory heap LSOM and the command 'secret' to increase

For my own sanity and to keep track of what I did, here's what I did.

You can see where I had already changed their values before the default.

Edit:

The command VMWare wanted to keep this secret is in their archives here:

http://vmware1140.rssing.com/Chan-4263175/all_p2889.html

I do not understand why VMware wants to keep this command of the community? Currently, I am testing now with the two heapsizes to the maximum configuration. My host is starting

He typed at the origin:

Dear Simon,

I tried:

vsish EI Setup/config/LSOM/intOpts/heapSize 2047

to increase the heapsize memory LSOM has allocated,

then did restart, without success on 192.168.240.55,

He is still unable to establish the Group of disks with memory error...

And this has changed to:

Dear Simon,

I tried the command you gave me in the SR to increase the

HEAPSIZE memory LSOM allocated, then did restart.

without success on 192.168.240.55.

He is still unable to establish the Group of disks with memory error...

  • All-in-one HP 1536dnf: cannot scan from the ADF and glass to a single PDF file

    Hello

    There is a user who needs to scan some papers, but he wanted to do the following:

    -scan of the papers of the ADF

    and

    -scan of glass papers

    and he wanted to merge all this into a single PDF file.

    The announcement of the user he could do before, we implemented a new computer.

    On my side, I did the installation of the drivers and as the default scanning software and indeed the scan works, but once you star scanning from ADF he will not identify any which paper on the glass and displays the message "no book on ADF.

    And when you start scanning from glass it will identify ADF even if there are some papers. Instead, it will scan the same page, if she stays or it will scan empty.

    Well. It became a long text, but any help will be welcome.

    Thanks in advance

    Hello

    It works this way because they are TWO different operations. There are a few free software around which allows us to merge several PDF files into one file. You should probably do this way. The following link is one of them:

    http://www.PDFSam.org/download/

    This free product allows you to divide a large file to many small files (such as the extraction of the chapters of a thick book) and also merge several pdf files into a pdf file.

    Note: use the free.

  • * Resolved * Windows backup. It creates no new backup periods. I have a single long period from 29/11/11 to 12/10/11.

    I made changes to the lineup. After you set up backups to run every day, I went into the Scheduler of tasks in the windows and found the windows backup task. I then modified to run 12 hours later to run a second time in a day.

    Is it because I moved in the planning of the backup by default a week at a time it does this.
    My real question is how can I delete older backups and keep the most recent. It gives me the option to delete all the.
    ****
    Update posted tonight 12/27/11
    Apparently, it was not a problem. The first backup period went from 11/12/11 to 12/25/11. A NEW BACKUP PERIOD JUST STARTED AUTOMATICALLY on 26/12/11. The total size of the first full backup period was 29.5 GB. not sure if it's a default size that must be reached before start a new backup set or if a certain percentage of my backup destination must be reached before creating another. In any case, after this experience, the file and folder backup set will begin a new period if the other gets to a certain size.

    Thanks for the reply. I appreciate it. In fact, I like the windows backup program. I work in Technical Support and to always direct people to Acronis, Ghost, which I've used Ghost before and like that also. During the action of Thanksgiving, I started to really dig into the windows 7 backup and Restore Center and there is more to that meeting the eye and it's free and ready to go in windows 7. I really recommend people now whereas before I used to steer customers people away from him. I used to think that you cannot retrieve the system image files as you could the ghost, but you can actually mount the backup of disk management by adding a virtual hard disk in the menu Actiion. pretty slick. I like the file and cause the backup folder part is kept the older versions as well as the most recent. I thought that the system images were not additional but felt they were. other that last compression on the backup images, the built-in Windows 7 backup solution is OK by me. I just wanted to learn more by posting here. try to learn as more not to complain. Thanks for all the answers.

  • Syntax to drop several disks in a single command ASM

    Hello

    We have 11.2.0.2 with 2 RAC on AIX 7.1 knots. We have the starts in ASM with NORMAL redundancy and the diskgroup has 100 (50 for a failgroup) and 50 for an another failgroup discs.

    We will drop 10 discs (5 a failgroup) and 5 from other failgroup since this diskgroup, so that all failgroups have the same number of disks (and sizes also).

    So, I need the syntax to drop all ASM 10 of the same diskgroup disks in a single request. Could help me in this area, please?

    I can try to use 10 commands, one for each disc to give up but, after the execution of each command/disc, the operation of rate rebalancing will take place and that will make us wait until the re - balance finish to execute the next command in the drop. To avoid time taking orders 10 running one by one, I would drop them all in a single command.

    for example, the discs that we will give up are below:

    Failgroup: FG1

    PATH NAME

    ----------------------- ---------------------

    / dev/DATAM_L0203_ORCLFG1 NAME ORCL_DATOS_0150

    / dev/DATAM_L0204_ORCLFG1 NAME ORCL_DATOS_0151

    / dev/DATAM_L0205_ORCLFG1 NAME ORCL_DATOS_0152

    / dev/DATAM_L0206_ORCLFG1 NAME ORCL_DATOS_0153

    / dev/DATAM_L0207_ORCLFG1 NAME ORCL_DATOS_0154

    Failgroup: FG2

    PATH NAME

    ----------------------- ---------------------

    / dev/DATAL_L0203_ORCLFG2 NAME ORCL_DATOS_0184

    / dev/DATAL_L0204_ORCLFG2 NAME ORCL_DATOS_0184

    / dev/DATAL_L0205_ORCLFG2 NAME ORCL_DATOS_0184

    / dev/DATAL_L0206_ORCLFG2 NAME ORCL_DATOS_0184

    / dev/DATAL_L0207_ORCLFG2 NAME ORCL_DATOS_0184

    Thank you very much

    for example

    alter diskgroup diskgroup_name drop disk ' / dev/oracle/disk197 ',' oracle/dev/disk198 ',' oracle/dev/disk199 ".

  • Can you have a cluster with a single host?

    Hello

    I'll put up a new VMware infrastructure, which includes a cluster with 2 guests in a place and a single ESX host in a second location.  They will all be managed by server unique vSphere.

    It is possible that the second site can earn an additional ESX host at some point in the future.  So, my question is if I have to create a cluster for the second site and have just the single host in it for now, so its ready if we add a second host?  Is it possible to have a cluster with a host, and what are the consequences of this?

    Thank you

    Joe

    Technically, Yes, you can have a Cluster to a single node and if you plan to add another node in the cluster later it makes sense to set up the first node.

    And, both from a technical point of view, but especially from a point of view BAU.  Mulitnode cluster promotion will be less intrusuve there is no additional software to add on the pre-existing main node, therefore you Board change will be less nervous about the piece of work, because it won't change the node pre - that does not exist.

    From a personal point of view my current client runs a number of single-node clusters, in their environment.

  • How to add md1000 2.18 TB disk array to ESX host

    Hi, I am very new to VMware, and I try to add a picture of 2.18 TB md1000 disk to an ESX host.  When I go through the storage add wizzard, I see that he sees the md1000 2.18 TB of capacity, but shows only 1.8 GB available.  Anyone know what kind of configuration, I need to do for all the show of 2.18 TB as being available?

    Thanks a lot for your suggestions.

    John

    2 TB is the maximum for a single LUN.  You need to decreate your size of the LUN to less than 2 TB.

    I went from a Win7 32-bit on a 64-bit win7 machine computer. Now, I get "this connection is not approved" on many pages, including support for Mozilla, Yahoo, send a mail to yahoo, etc. The only thing that has changed is my computer. Everything worked on the 32-bit system. I tried DELL-no-help, I tried Norton-no-help - I tried all published recommendations - nothing helped. Can someone give an explanation of how solve this incompatibility (presumed) Win7 64 bit computers? How can I quickly and absolutely get rid of MESSAGES "THIS CONNECTION IS UNTRUSTED"?
    Thanks for ANY help from an expert.

    Right after that I posted this problem it seemed the solution:
    I noticed a pop-up, named "BROWSERSAFEGUARD" who has attempted to set my computer to a "cleaner" for a price. I checked in my installed programs if there was a "Browsersafeguard" and he was there. I uninstalled it, check "incompatible with my system" and my computer turned on like never before. Lightning fast connections and no message more "this connection is not approved. Wow. It took me 7 days to find it. Hope this will help you, too.

  • Entry value change when he went from teststand for labview.

    Hi all

    I try to spend my labview VI value hexadecimal teststand. When I run the VI independently giving the value as 00000010 I get the expected results of the VI.  But even when value is passed through local variable teststand, when it reached VI of entry it was conerted to 000000 A 0 and so I'm getting wrong output.

    I am not able to understand how the value goes to the value of the input parameter when she went from teststand for labview.

    Any ideas?

    I discovered the error.  I was entering the value in the wrong format in teststand... instead of 0 x 10 I've entered only 010 and was therefore is converted to A.

  • Error "host cannot communicate with all other nodes in the cluster of enabeld VSAN.

    Hello community,

    We have a problem (?).

    We have a cluster VSAN enabled with four hosts. Everything seems perfect,

    -the configuration is good,

    -Displays the page state VSAN "network status: (green arrow) Normal."

    -Displays the disk management page "status: healthy" for all of our groups of disks.

    -Same 'esxcli vsan cluster get"on each host returns a 'HEALTHY '.

    But we have a yellow exclamation littly on each host 'host cannot communicate with all other nodes in the cluster of enabeld VSAN.

    Anyone with the same problem? Anyone with an idea or a hint?

  • install vCSA single host and manage this host of "inside".

    Hello

    This is probably a stupid question, but I have found no reference or information about it:

    is it possible to install vCSA on a single host, which will be then handled by the same vCSA?

    background: there is only a single physical server available.

    are there disadvantages with such a configuration, and if there is, which could be problematic? same starting the server cannot, because it does not find the vCSA server to validate its license?

    I know that an update manager will not be usable, as the upgrade of the host, all virtual machines must be turned off and the host is in maintenance mode. This isn't a problem, as a manual upgrade of a single server is really easy.

    Best regards

    Mayr Oskar

    I agree with Gortee about the DVS, because that would be a factor limiting.  Since it is a single host it is useless to DVS anyway (unless you need the ability to scrutinize traffic in native mode).  I use the full vCenters blown on my main data centers, but I have a bunch runs exactly as you mentioned (about 60 sites with single host + VCSA + vStandard Switch).  No problems.  Good thing is that you can define the order of auto start since you do not HA.

  • Maintenance - VMotion mode single host?

    If I HA and DRS in fully automated and I put a host in maintenance mode will all be moving VMS to multiple hosts or they will move to a single host, then DRS to multiple hosts? We have 23 hosts in the cluster.

    Thank you

    DRS will load balance the guests on the other hosts in the cluster.

  • I edited a photo in Lightroom 5 and when I exported the completed picture, she went from a 1.3 MB to a 542KB file.  Everything I read says it is fine and I don't lose any resolution - but I wanted to ask the community.  Thoughts?

    You may not have lost any resolution... or you can understand the word "resolution" bad

    Resolution isn't the file size, which are the numbers you are quoting. So the 1.3 MB changing to 542KB does not indicate a change in resolution. If you export the picture and let the box that says "Resize to Fit" disabled, so you don't waste no resolution at all, even if the file size has changed.

  • Upgrade of a single host with Shared Storage

    Getting ready to upgrade my ESX 3.5 hosts to vSphere.  I've already upgraded to vCenter.  I have two hosts managed by vSphere, and both hosts have a storage area of channel shared fiber that guests are on.  Each server can see all shared data stores.  I want to upgrade a single host first, then later upgrade the other host.  I've migrated the guests running to 2nd host whose I am not upgraded at the moment.

    My question is can I upgrade the first host using Update Manager?  What happens to guests in data warehouses that run on 2nd hosts?  Will they be affected?

    > My question is can I upgrade the first host using Update Manager?

    Yes.

    > What will happen to customers in data stores that run on 2nd hosts? Will they be affected?

    They will not be affected.
