DPM 2012 R2 All backups fail with recovery point volume not available after resizing OS disk RRS feed

  • Question

  • I resized the C drive partition of my DPM server (the data is on a separate dedicated array) and everything failed. I put it back but everything is still failing with the same problem as here:

    DPM 2007: The recovery point volume is not available?

    I've run chkdsk for a couple and both have given the following after doing 3 stages:

    Windows has scanned the file system and found no problems.
    No further action is required.

    The backups still fail and the only error information I can find in the event logs is:

    Backup job for datasource: Online\<VM name> on production server: <host FQDN> failed.

    How can I find out what the problem actually is?

    Is it possible to resize the C drive containing a DPM install? If so what can it be safely resized to? It easily met the minimum requirements and I don't know of anything in the documentation that says resizing the OS disk may cause issues.

  • Hi,

    Resizing the boot partition (usually C:) should not effect DPM in any way.  DPM writes directly to it's volumes contained in the storage pool and not through the mount points on the C: drive.    So is the DPM UI showing missing volume next to some data sources ?   Try doing a DPM disk rescan and see if that removes the missing volume flag.

  • What it shouldn't do and what it has done seem to be different things! The storage Pool Disk is listed as online as normal

    >is the DPM UI showing missing volume next to some data sources ?

    I'm not sure what you're referring to here but the PG members look normal except for the error status in the Protection Status column. I've had to open a call with Microsoft support, hopefully they'll get to the bottom of it. If I find out what happened I'll update this thread.
