Hello,
My (writeback enabled) bcache cache device had a temporary failure, but seems to have fully recovered (it may have been overheating or a loose cable).
>From the last kernel messages, it seems that bcache tried to flush the dirty data, but failed, and then stopped the cache device.
After a reboot, the bcacheX device indeed no longer has an associated cache set..
I think in my case the cache device is in perfect shape again and still has all the data, so I would really like bcache to attach it again so that the dirty cache data is not lost.
Is there a way to do that?
(Yes, I will still replace the device afterwards)
(I am pretty sure that just re-attaching the cacheset will make bcache forget that there was a previous association and will wipe the corresponding metadata).
Best,
Nikolaus
