[PVE-User] Filesystem corruption on a VM?

OK, with 16GB of ram 5 days passed without FS errors.


Also, the other VM, same stretch kernel, roughly same configuration,
start to expose same errors:

 Nov 18 10:12:21 vdmsv2 kernel: [584252.496880] EXT4-fs error (device sda6): ext4_mb_generate_buddy:758: group 104, block bitmap and bg descriptor inconsistent: 2048 vs 32768 free clusters
 Nov 18 10:12:21 vdmsv2 kernel: [584252.590564] JBD2: Spotted dirty metadata buffer (dev = sda6, blocknr = 0). There's a risk of filesystem corruption in case of system crash.

Note that this VM was built *AFTER* my SAN glitches happens.
