        *** Some devices missing

My CACHE disk stays 'spun up' (SSD) but CACHE2 has no read / write activity and spins down when it hits the hour mark (the hour of disk inactivity).

 

That command above shows device missing. CACHE is /dev/sdl & CACHE2 is /dev/sdk

Both disks are there and showing without error... However the CACHE isn't treating them equally - How might I go about fixing this?

 

Diagnostics attached.

 

Thanks

Also got this email message this morning from my Unraid:

Event: Unraid Cache disk message
Subject: Warning [RAPTOR] - Cache pool BTRFS too many profiles (You can ignore this warning when a cache pool balance operation is in progress)
Description: OCZ-VECTOR180_A22NB061516000354 (sdl)
Importance: warning

 

Cache2 dropped out, can't see why because diags are after rebooting, recommend replacing the cables to rule them out, you should then be able to re-added it, but backup any important cache data and clear the dropped device before trying to add it back with:

 

blkdiscard /dev/sdX

 

replace X with correct identifier

sorted

 

Just needed a balance in the end

Good, but don't forget to replace cables, SSDs don't dropout for no reason.
