Granular Restore Hyper-V fail

Hi community,

I m trying to restore a single file of a virtual machine in an Hyper-V environnement.

We are using NEtworker 8.2.3 with NMM 8.2.3 and a Data Domain with direct access for that virtual Machine.

When i try to mount the nwfs i get the following error in NWFS raw file :.

NSR error 2 %s 1 0 28 The directory is not empty .Can anyone help me? .Thanks .Greg

    Hi,

    have you checked if there is an old mount? Maybe cleaning it up failed.

    Hi Greg,

    Let's try to get some more information by adding debug to NWFS.

    Please create the following registry key, and give it a value of 3 (to start with):

    HKEY_LOCAL_MACHINE\SOFTWARE\Legato\NetWorker\NWFS\DebugLevel

    Also, did you get any error in the nmm.raw file and/or the daemon.aw files on both, server and client at the time of the restore?

    Based on the message "10.10.2016 09:56:19  3 5 0 3156 6828 0 (HYPERV Host) (pid6828) NSR error Configured to perform Non-Immediate recover, exiting, this could indicate some problems setting up the client direct session.

    Also please remember to close NMM GUi and reopen it each time you attempt a new restore.

    Thank you,

    Carlos

    Hello Carlos,

    I put the reg key. Stupid question: i am supposed to restart my host to make the key working, am i right?

    And no, no entry in NMM or Daemon.raw (Hyper-V host and networker server) at the restore time)

    Thanks for your help

    Greg

    Hello Carlos,

    After having inserted the reg key and rebooting the server

    10-11-2016 2-58-27 PM.jpg

    I don't see any differnce in th Nwfs or NMM log file. Hyper-V host is currently running on Windows 2012. Does it make any différences?

    Thanks for your help.

    Cheers

    Greg
