Backups - QNAP iSCSI - ReFS Corrupt Volume

[CHiLL]

We received a bunch of emails last night that all of our backups failed due to not being able to access the backup location. The backup device is a QNAP TVS-1271-U-RP with 8x 3TB drives in a iSCSI RAID6 array and ReFS as the file system.

 

The error VEEAM reported was:

Could not perform threshold check for backup location "E:" due to space info retrievement fail!

[bACKUP.SJW.Internal] Failed to create directory 'E:\Server1' Error: Failed to call RPC function 'FcCreateDir': The volume repair was not successful. Cannot create folder. Folder path: [E:\SJW-APP1].

Error: The volume repair was not successful.

I cannot access the E: drive from This PC and I receive the following message:

E:\ is not accessible.

The volume repair was not successful.

 

As this is our backup solution, we haven't lost any live data, however I want to get this sorted as soon as possible, as our secondary backups are now our primary backups and a couple of weeks out of date. I suspect I've lost all backups from the QNAP.

 

This is the first time I've come across this issue, is there a way to recover from this without data loss? If not and I lose all that data, do I just format the volume from Disk Management in Windows (Server 2019) and start again, or do I have to do something from the QNAP interface?

An update if anyone else comes across this thread.

 

Further investigation lead to discovering that the QNAP was rebooting itself under heavy load, which was causing the iSCSI LUN to break and the RAID to resync every time. I raised the issue with QNAP support and they determined it was a hardware fault from the logs I submitted. They suspected a RAM issue, though memtest ruled that out, so they surmised that it must be an issue with the CPU or motherboard. The cost for out-of-warranty repair and out-of-action time wasn't justifiable, especially when you consider the cost of a new unit and the three year warranty as standard.

Whilst I didn't have the same direct issue you did, my QNAP TS-1079 Pro died on me earlier this year out the blue. First 2 hard drives genuinely died, but after slotting in replacements numerous other drives started dropping as well. Testing those drives externally indicated no problems. After buying 3 x 4TB drives which weren't being detected, I more or less came to the conclusion that the backplane had died. Took the unit apart, couldn't see any damage, corrosion, bad caps, burn marks or anything. Cleaned the whole unit out but no difference.

 

QNAP support told me that the unit had long since been end of lifed and there were no spare parts available anywhere. That hurt, since our unit was just hitting the 3 year old mark.

 

Love QNAP's software, but your hardware issue does make me wonder about the quality of their hardware...
