We have a number of Qnap NAS's using the Linux agent (edit: as a repository) with no problems but one is causing issues and I am unable to work out why. To get the agent working in the first place I have installed IPKG and from there installed Perl. Once installed the agent works fine. I have a couple of other boxes working and they have been for a few months or so with no issues.
This particular box worked fine for a few weeks and then had an issue during the backup causing it to fail. Once it had failed the retry also failed. Looking at the logs it appeared that the ls and df commands being sent to the box were unable to run due to the limited options available on the NAS (lack of ls --color and df -P). Installing the coreutils IPKG package resolved those issues but I now get the following:
Code: Select all
[23.04.2012 18:00:29] <01> Error CheckStorage failed (System.Exception)
[23.04.2012 18:00:29] <01> Error at Veeam.Backup.AgentProvider.CBackupClient.CheckStorage(String storageFilename, ECheckStorageLevel level)
[23.04.2012 18:00:29] <01> Error at Veeam.Backup.Core.CStorageEx.CheckConsistent(ECheckStorageLevel level)
[23.04.2012 18:00:29] <01> Error at Veeam.Backup.Core.CSyntStorageAlg.PrepareStorages(CPoint currPoint, CPoint prevPoint)
The firmware revisions are identical across all the devices I have. The other devices have not had coreutils installed, even if the backup fails and goes into retry mode I do NOT have the same issues, the retry works fine.
If I reseed the backup from scratch it works fine, but as soon as an error occurs I am back to square one.
For some reason this device is not working the same as the others but all I have to work on is the above. Has anybody got any ideas that could help?
Thanks.
