I've been using VDR 2.0.1 for a few months now, with two 500GB NFS shares mapped in following the guides available. This has been working far better than the previous CIFS method I was using, and I've been happy with it until a problem that started happening this week.
I can no longer backup anything to one of the backup shares (the other is working fine). Every VM that tries to backup to this share fails with the following error;
Trouble writing to destination, error -102 (I/O Error).
I ran an integrity check, which first time passed ok, but second time failed with this message;
Can't load restore point tree for <date>, error -2249 (Could not find restore point)
So, I then began troubleshooting, and discovered the following;
If I check on the VDR console itself, both NFS shares are mounted ok as 'rw' with no errors
I can 'touch' a file on the problem share, and it creates fine
In the VDR vCenter console, there are no 'damaged' restore points listed in the 'restore' tab
If I stop datarecovery, delete the catalog files for the problem share, restart datarecovery and then run an integrity check, this completes fine and the catalog files re-create ok.
I can restore a VM fine from the share
There's plenty of space left on the shares according to the vDR appliance.
I've rebooted the vDR appliance (obviously) and done check on the host exporting the NFS share. No issues whatsoever. Therefore, I'm at a total loss. Of the threads i can find for others experiencing similar problems, nothing stands out. The changes suggested you make to limits.conf and datarecovery.ini I'd already done months ago, and they were working fine.
