Error messages @ boot

[jkbuckethead]

Not sure if this is the best place for it, but for lack of a dedicated hardware forum here it is.

When I boot my server, the server monitor shows the following:

localhost login: [ 80.070617] CIFS VFS: cifs_mount failed w/return code = -6
[ 80.172480] CIFS VFS: cifs_mount failed w/return code = -6
[ 427.307614] EXT4-fs error (device sdd1): ext4_mb_generate_buddy:757 group 17041, block bitmap and bg descriptor inconsistent: 1974 vs 1929 free clusters

From what I can tell in amahi, all my drives show connected, and all partitions are as expected. Should I be concerned about this error?

Does it signal a potential drive failure?

Is there a way to fix it?

Hard to say if this is a drive failure or not.

Have you searched the internet? I did not find anything for the error code, but might be some guidance out there.
