Hello,
We recently built Lustre 2.5.1 with kernel 2.6.32-431.5.1.el6 for CentOS-6.5 We have been
getting these crashes whenever we try to run mkfs.lustre
In the crash material you will notice that we are running mkfs.lustre.bin - this was done
so we could first gather the full command lines. The open files, which are not on Lustre,
seem to be getting corrupted on crash.
I have already applied the patch associated with LU4778, but it does nopt seem to have
changed anything.
mkfs.lustre.bin --reformat --fsname hss3-rr1 --mdt --mgs --mkfsoptions='-m 0 -O
