[Lustre-discuss] Lustre Mount Crashing

[Charles Taylor]

We lost our MDS/MGS to a power failure yesterday evening.     Just to  
be safe, we ran e2fsck on the combined MDT/MGT and there were only a  
couple of minor complaints about HTREE issues that it fixed.    The  
MDT/MGT now fsck's cleanly.     The problem is that, despite the clean  
e2fsck, the MGS is crashing in the lustre mount code when attempting  
to mount the MDT.

It is a scratch file system so it is not backed up.   Still, it is a  
pain to lose the data.    I'm assuming this is not normal and there is  
not much in the manual about doing anything more than e2fsck but I  
want to ask if anyone else has seem something like this before and  
might have some additional suggestions before I trash the data and  
reformat the file system.

Thanks,
