e2fsck fixed it: The OST is now running since 40 minutes without problems:

e2fsck 1.41.6.sun1 (30-May-2009)
lustre1-OST0005: recovering journal
lustre1-OST0005 has been mounted 72 times without being checked, check forced.
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure

Pass 3: Checking directory connectivity

Inode 17769156 ref count is 2, should be 1.  Fix<y>? yes

Unattached zero-length inode 17883901.  Clear<y>? yes

Pass 5: Checking group summary information

lustre1-OST0005: ***** FILE SYSTEM WAS MODIFIED *****
lustre1-OST0005: 44279/488382464 files (15.4% non-contiguous), 280329314/1953524992 blocks



But shouldn't the journal of ext3/ldiskfs make running e2fsck unnecessary?


Have a nice weekend and thanks a lot for the fast reply!
