Hi list,
I have a RAID1 Btrfs (on sdb and sdc) behind bcache (on nvme0n1p4):
What's the cache mode? Writeback, writethrough, writearound?
Sorry I forgot that important information: mode was Writeback.
You could try to detach the *cache* from the bcache devices, and then try to
use the bcache devices as before; it should be possible and harmless,
*unless* the cache mode is "writeback". If it's "writeback", things are more
complicated, and I'll leave them to more experienced people around.
ok, as I have Writeback, I'll wait for further instructions.
IMPORANT: The kernel logs below indicate that bcache failed to do IO on the
cache device. It could be a hardware problem with your NVMe device, so I
suggest you look at its SMART, ASAP.
Yes, the nvme is having problem... I'll replace it ASAP.
Thanks for your reply Pavel,
Best regards,
