Map of RDM file size?

• Simple mapping of RDM vs file several mapping of RDM files?

  Hello

  When you configure Microsoft Cluster nodes in a scenario of cluster-across-boxes (stream clustering) (two ESXi hosts, two-node cluster MSCS, with a bow on each ESXi host), I realize that using physical RDM Mode (pass-through RDM) is the way to go.  I also usually have to locate the C: drive (zero eager thick) for each cluster node on another volume VMFS to ensure two distinct areas of failure.  So, for example the C: drive of node of Cluster 1 (VM1) could be the Datastore1 and the C: drive of Cluster 2 node (VM2) might be on Datastore2.  Similarly, I always created RDM mapping files for each virtual computer as well, pointing to the same raw LUN.  For example, I would put the mapping of RDM for the quorum shared LUN on Datastore1 for VM1 and file a new mapping file RDM pointing to the same conditions of quorum LUN on Datastore2 for VM2.  In this way, the failure of Datastore1 will affect only VM1 and VM2affect only the failure of Datastore2 .  I did this for years (probably since ESX 2.5) and MSCS works very well in this configuration.

  However, I was re-reading of the official documentation of "configuration of Failover Clustering and the Microsoft Cluster Service" VMware and noticed that specific VMware at several locations as "a map file of RDM single and shared for each clustered disk is necessary."  In other words, they call for me to select 'existing hard drive' VM2, and then tap the RDM mapping file that I created on VM1, rather than creating a new fresh RDM for VM2 mapping file.  This seems to be "less safe" because the failure of Datastore1, or RDM 1 mapping file corruption, would result in the failure of VM2.  A separate mapping RDM for VM2, on a separate data store file would provide two distinct areas fault to two virtual machines.

  Does anyone know why VMware requires a shared single RDM mapping file?  Are there specific problems, caused by the presence of two separate files RDM mapping?

  Thank you

  It seems that VMware has posted a KB that explicitly indicates that a pointer/mapping "single" RDM file must be used on all nodes of the cluster.  So I guess this settles my question!

• New hard disc RDM - selection of the mapping of rdm file creation

  Hi all

  I am trying to automate the creation of new RDM disks for virtual machines.

  Watch us row map separately files on a data store named, here is the sequence of orders.

  1. because I can't find the PoweCLI method to create the mapping of RDM file, I use vmkfs as below:

  vmkfstools - z/vfms/devices/disks/naa. XXXX01 /vmfs/volumes/clustername/SharedDisk/hostname/disk1.vmdk

  2. now, we have the mapping of rdm file, I would like to create a new physical disk RDM.

  New-harddisk - Contorller $controller DiskType - RawPhysical - DeviceName ' / vfms, devices, disks, naa.» XXXX01"- vm $vm

  However, this creates a new mapping file. I don't see how I can use the one I created above.

  Am I missing something? The operation of fixing using the existing mapping of RDM file is insignificant in the GUI.

  No, not missing anything.

  This scenario is not possible with the cmdlet New-hard drive I'm afraid.

  You can use a script that uses the ReconfigVM method.

  Through the Device.Backing property, you can specify the location of the VMDK file

• Clean map of RDM files

  I just want to get clarification.  I removed some RDM tonight a virtual machine, but instead of removing and deleting, I just went with the removal of the RDM.  I now find myself with some of the mapping files and was curious to know if its ok just to remove @ this point?

  Hello

  The withdrawal of RDM mapping files will not cause any problem. When you add RDM back it will create again. It's so safe.

• Virtual RDM: mapping in the vm, VMFS folder file size

  Hello

  I just migrated an iscsi LUN previously managed the MS iscsi initiator (running inside a machine virtual w2k03) to ESX iscsi sw, preserving the data.

  I used RDM (raw device mapping) and I had to use 'virtual' because 'physical' hanged the VM at startup of the operating system.

  The iscsi LUN is 1 TB, with about 60GB used.

  I noticed that on the volume VMFS file mapping for the virtual machine is about 2 GB: happen when on the iscsi LUN more space will be used? And if it goes, is there a rule to calculate how much?

  I'm worried I might risk running out of space on the VMFS volume because of the mapping of RDM file...

  Thank you

  Guido

  It's just a pointer to the original disc of RDM.   I have a few MS Cluster in my setup. For 18 GB RDM Lun he creates about 100 MB.

• OK to remove the mapping of RDM?

  I need to cold migrate some virtual machines with virtual RDM mode on new servers. I'll introduce the RDM with different numbers of LUNS on the target hosts. My co worker suggests that when you remove the ROW before the migration of the cold, you can not delete the mapping file, otherwise this will cause data corruption, so it selects the removal of the option of vm (not remove and delete).

  My understanding is the file ROW is just a mapping file and is safe to delete. My thought is that delete saves space and accelerates the migration time.

  RDM files can simply be removed without data corruption?, most vmware articles suggest they can and they're just mapping files.

  When the virtual machine allows you new hosts, a new virtual RDM will be added when the lun is presented to the new hosts.

  Yes, you can delete the ROW with removal of the VM disk option before the migration of the cold.

  It won't cause any data corruption that all data is on LUN storage.

  RDM file contain only for the LUN mapping information.

  Once you have completed the migration of VM, you can add RDM LUN to VM, just make sure that you attach Correct RDM LUN to VM.

• Hi, my places.sqlite file size is 30 720 KB I reached the maximum size, is there a maximum size for this. Visited links are is more changing color.

  Hello
  My places.sqlite file size is 30 720 KB I reached the maximum size, is there a maximum size for this.
  Suddenly the visited links don't change is no longer the font color, that I prepare for an exam, I need visited issues to change color, to follow up on issues that I ended. But if I delete a few days of history, then again once, most visited links change color and then it stops, it seems that something is getting full and not able to accommodate more? Why my visited links don't change color after a number of visits? I would like to make a back up of the file places.sqlite. So I tried everything to remove the profile, uninstalling reinstalling, creating a new profile, and then copy paste places.sqlite etc, but as mentioned after a few visits, visited links is no longer change color, if I delete a few days in history and then a few visits is again change color and then stop again, so what should I increase so that my quota of visited links is increased , I also tried tweaking about: config and there has been no result. Although I was not really convinced that _pages growing brower.history_max (don't remember the name, but I'm sure you get the idea) will help.
  Seems that while my visited links change color, quota is met and only if I delete the history of a few days will I get some links most visited to change color. Can someone enlighten us? As mentioned that my places.sqlite file size is 30 720 KB so I think maybe this has something to do with it? Would be very grateful if someone could help me. Thank you.

  Sorry it is not looking good.

  1. Unlike bookmarks history is not saved in Firefox.
  2. There is a possibility using Windows.
  3. Sync is not expected to back up things until the synchronization server
  4. If places.sqlite does not sort itself you may have to re-create remove it. You will lose your history, but can still access indirectly IF you have saved a copy of the appropriate
  5. Different databases to try to create new profiles
  1. History
     is rather less robust than bookmarks, you should deliberately somehow return it upward, but it's too late now
  2. Earlier versions of Windows
     This is really the last chance. Make sure you have some places.sqlite you saved. Always before and after any attempt to restore the backup. Windows must be able to provide a previous version. One of these versions may be usable as is; or can be used after a repair with housekeeping. Of course, this is not the latest version but it should help.
  3. Sync is not a server backup service.
     Sync is intended to save on another device, no backup is the fact that the second device then contains synchronized information. IIRC Sync development ceased, and the replacement when available may include a server backup option.
  4. Recreate the database of bookmarks (including history)
     Unfortunately, recess can only use saved bookmarks, there is no saved history to use. Once the database is re-created, it will continue to store the history but it loses the existing history. This time take steps to save on a regular basis.
     • The backup profile or at least the places.sqlite in this

     • http://KB.mozillazine.org/Bookmarks_history_and_toolbar_buttons_not_working_-_Firefox#Rebuild_Places_database
  5. Use the new profiles for database testing.
  
  To simplify comparison of the results of the database different files create one or more new additional profiles. Then try to smash the places.sqlite file into the test profile with any other places.sqlite, you want to try. Allows you to directly compare the databases, without seeking to use sync and without changing the Firefox profile work unnecessarily. You can keep a reference profile of studies with the best of the profiles of any shows results of history; According to the best recreated or corrupted database is.
  • Use the Profile Manager to create and delete profiles Firefox
  • CARE, do not rename or delete profiles created once or use anything other than empty folders when they are created. Don't nest in the other profiles. (At least until you know exactly how it behaves - post back if you never consider such actions)

• for the iBooks file size question

  Thanks in advance!

  Carolyn

  Hi there is Carolyn!

  Looks like you are looking to see what type of file sizes to wait for iBooks. This article seems to answer this question directly:

  On iBooks

  Size of files

  The typical book is about 2 MB. The books that contain improved, audio or video, features vary in size depending on the content. Enhanced books could take longer to download than a standard book.

  The iBook Store also offers manuals that might be larger than 1 to 2 GB of file size. You need a Wi - Fi download them on an iOS device. Time to download textbooks vary depending on your Internet connection.

• Designjet T120: Can't trace file size D (T120)-specific PDF drawing

  Hi all

  Having problems trying to draw a PDF specific drawing D-size (SolidWorks saves) on our plotter T120.  It plots just fine in the sizes A, B and C, but when I try D, it just hangs, then times out with an error.  I tried to update drivers, run the HP diagnostic utility, run the utility from Microsoft, etc. but nothing seems to work.  I traced several other designs in the past in D format without any problem (tried a while ago with a different design of PDF and it worked fine).  Looking for ideas...

  In which case it is important:

  * Wireless printing

  * The PDF file size is 1.30 MB (spools up quickly to 13.4MB/15.7MB then crashes)

• What is the best file size to create an animated logo

  I'm trying to animate a corporate lodge for a chart of the opening of a video. Can you recommend what size of files and the resolution is the best? If I can get a JPEG will apply the same specifications of file size.

  All your ideas and suggestions are greatly appreciated.

  That's exactly how I would do it (too).

  Applications of paint have wonderful tools to bump-out parts of an image, or to 'flatten' areas (cleaning/denoising artifact jpg)...

  size/resolution: depends on the 'action', if you do not zoom in, 1920 x 1080 video hires, is good enough, if you do some z axis fun (fly Thru), a much higher res is needed.

  suggestion: If the logo contains the fonts/text or simple forms, I re - who would enact in movement. because it acts as a 'vector' = resolution independently, as in this example:

• Why the same photo's file size different in Photos and in the Finder?

  I have a photo size 4608 x 3456. When I open the file information in the Apple's Photos app, it says that the file is 7.8 MB.
