Hello Fellow Unraiders,
Today the error log of Unraid showed a lot of BTRFS errors, so I searched what you can do and what causes it. Unfortunately I did not find the cause of the issues.
Anyone who knows what is the best thing todo at this point. Diagnostics are attached. The harddrives are 2 SAMSUNG_MZVLB256HAHQ.
Unraid version 6.8.1
Found this command
