Re: [MooseFS-Users] Last error

[David M. <dav...@pr...>]

Hi Jay,

I encounter this occasionally and have usually found no issues with the disks according to SMART. Can you post your smartctl output? I was advised that if there are "reallocated sectors" in the smart summary, this could relate to the problem. Alternatively, if your disk(s) have compression enabled, this may be causing errors.

One thing you could try is mark the disk for removal, reformat it when ready, then re-add it to the cluster.

Cheers,
Dave
