After running 'tunefs.lustre -writeconf /dev/mdt01' on my combined mdt/mgs I am unable to mount the device - this was following a mds crash. This is on sles 10sp2, 2.6.16.60-0.31, with 1.8.0. A couple of OSTs and a client are installed on the same machine, but they haven’t been mounted since the problem occurred.<br><br>In the hope that this might be related to a corrupted CATALOGS file (like in bug 16002), I mounted the mdt with ldiskfs and removed the file, but still get the same problems.<br><br>Can anyone lend any advice on any recovery steps they might take?<br><br>Sep 10 14:12:35 uklust01 kernel: kjournald starting.
