We went via 2.4.2 to 2.5.1 which worked. Possibly 2.1 to 2.5 might be too great a version leap.

I formatted a file system with Lustre 2.1.5, and have used it for a while.  I just upgraded to Lustre 2.5.0.  I thought that I should be able to mount all the targets.  I was able to mount the MDT without a problem.  When I try to mount an OST, I get this error:

Should this have worked?  Any advice on how to fix this?
