Help with possibly corrupt vm disk

[lucacraft89]

i have a vm (id 214) that whenever i try to

cp

the disk or clone it or make a backup of the vm i get all I/O related errors, i tried running

badblocks

and

fsck

both on the storage drive and inside of the VM but no luck.

Anyone has ideas?

Backing storage for the VM disk might be going bad. Run a SMART long test and prepare to restore the VM from backup; you might need to replace the physical disk

SOLVED: one singular SAS drive of the entire array of good drives was making the raid controller flag them all as bad and then slowing them down, replaced it and now works
