Description

Similar error occurred on 2 osts, 2 different nodes using 2 different DDN raid controllers. The ost aborted journal and was remounted RO.

Subsequent e2fsck successfully cleared the problem inodes and the targets re-mounted. 

We don't have extra_isize showing as a file system feature on these OST devs, or at least it doesn't show up in dumpe2fs output.

The OSTs have been up and running ok since last September or so.
