After 4-5 years happy usage of Debian9 + Proxmox5.2 + Xpenology dsm 5.2 I upgraded six months ago to DSM6.2.3 Proxmox6.3-3 Debian10. All went well, until a few weeks ago...
One night at 3am my volume 2 crashed!
Since then I can read my shares from volume 2, but not write. It is read-only. I suspect the activation of write back cache in proxmox is the reason.
Status of SMART and all my harddrives and raid controller is just fine, so I suspect no hardware issue.
After using google, this forum and youtube I still have no solution.
The crashed volume has all my music, video's, photo's and documents. I have a spare 3TB WD RED HD directly connected to the MB and copied most importend files.
However I have a backup of the most important files, I prefer to restore the crashed volume, but starting to become a bit desparate.
I think the solution is to stop /dev/md3 and re-create /dev/md3 with the same values, but something is keeps /dev/md3 bussy and prevents me to do. Could someone please help me?
Setup:
- Hardware: Asrock µATX Bxxx(I forgot), Adaptec 8158Z raid controller with 4 x 3TB WD RED (2 new, 2 second hand and already replaced b'cos broken within waranty)
-Software: XPenology DSM6.2.3 Proxmox6.3-3 Debian10
-Xpenology: Volume1 is 12GB and has the OS (i guess?), Volume2 is single unprotected 8TB ext4 and has all my shares. 4GB RAM and 2 cores.
