I’m having trouble with a filesystem after a planned outage. I’m new to Lustre, but I’ll do my best to explain what I’m seeing.

In general, while it is possible to have mismatched client and server versions, it is never a good idea to run different Lustre versions on the servers.
Cheers, Andreas
When I brought the system up, it reported the used space incorrectly (df –h shows 166T total, 150T used and 7.1 T free)
· I unmounted and ran e2fsck on all of the OST’s and the MDS without error, but when I remounted everything the error persisted.
· When I ran lfsck in read-only mode, it basically showed all of the files on the two OST’s of a single OSS as “not created”.
Is there a way to save this data?
Any help or suggestions would be greatly appreciated.
