Recently our main production file system experienced a outage which has
required a run of e2fsck on the back end OSTs. During the run we encountered
some issues which might lead to data lost. We would like to ask Intel engineers
who have a better understanding of the ext4 filesystem to look at the logs
and report back what will be lost and how safe is it to repair. Their are
two logs attached to this ticket. One is for raw data and the other, bad_luns.out,
is the one we are most concern about.
