Hi all,
I am using Lustre 2.5.3 under CentOS 6.5 both servers and clients and
after removing 300.000 files (from 1.600.000 files), only 163008Kb could
be reduced on MDT, but it keeps showing a 100% usage:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/vglustre-MDT
70766580 68563552 0 100% /lustre/mdt
The lustre file system is using 6 OSTs of 30TB size
The system mounts without problems, MDT backups (using tar) can be done
and the whole file system seems to work fine, but I can not manage to
reduce
the MDT usage. The only thing is that yesterday the whole cluster
system, due
to an electrical problem, went down suddenly, without been protected by
our UPS.
Any chance to be related with keeping on 100% usage?
I am worried with this issue. Should I?
Apart from using a bigger disk on MDT, is here anything that can be
done?
Any suggestions are welcomed
Best regards
