[Lustre-discuss] Can't Create New Files

Hi all,

I'm running into a rather strange problem where new files cannot be
created (lustre 1.6.6), but existing files can be modified and even
deleted.

The MDS reports: 
LustreError: X:0:(mds_open.c:431:mds_create_objects()) error creating
objects for inode Y:

For a large subset of inodes.

The OSTs, MDT all show as 'healthy', and an e2fsck had recently been run
on all of the lustre storage components prior to the problem presenting
itself. Also, all partitions are no-where close to being full (much
greater then 5% free)

Is this fairly common? Is the solution as trivial as a writeconf or
tunefs call? I couldn't find any reference to this problem in the
lustre-discuss archives so I figured I'd ask if anyone else has seen
this.

Thank you,
Adam
