Hi,
Find below the ouput of df command & the contents of /proc/mdstat file.
[root@bangapps root]# df -k

As you can see /logs is 100% full. I am asked to reduce /backup and
increase /logs.
Please let me know if the following commands would do the needful.
umount /backup
e2fsadm -L -40G /dev/vg00/backup
mount /dev/vg00/backup /backup
umount /logs
e2fsadm -L +40G /dev/vg00/logs
mount /dev/vg00/logs /logs
Thanks & Regards,
