Description

During some maintenance today we did run read-only fsck on all our OSTs in one of our file systems after shutting down the file system. (All OSTs are unmounted.)

On some OSTs we see these errors:

sudo e2fsck -v -f -n /dev/mapper/ost_lustre01_1
e2fsck 1.41.90.wc4 (01-Sep-2011)
MMP interval is 13 seconds and total wait time is 54 seconds. Please wait...

We have not yet attempted to mount these OSTs. Can these errors be ignored? Or should we just let fsck fix them?
