[Lustre-discuss] LustreError: error creating objects !!!!

[Pe.Herb]

Hi all,
I'm using lustre 1.8.0 on CentOS 5.0.
I have a problem when MDS is restarted (forced).
After, I mount lustre on MDS, the following are logs on MDS:
Sep 26 01:43:09 MDS2 kernel: LustreError:
14452:0:(mds_open.c:432:mds_create_objects()) error creating objects for
inode 20945086: rc = -5
Sep 26 01:43:09 MDS2 kernel: LustreError:
14455:0:(mds_open.c:432:mds_create_objects()) error creating objects for
inode 20945086: rc = -5
Sep 26 01:43:10 MDS2 kernel: LustreError:
14441:0:(mds_open.c:432:mds_create_objects()) error creating objects for
inode 20945086: rc = -5
Sep 26 01:43:10 MDS2 kernel: LustreError:
14456:0:(mds_open.c:432:mds_create_objects()) error creating objects for
inode 20945086: rc = -5
....
Check df -h on clients, it's OK.
But client can't read or write data to disk (storage lustre).
mdt and mds on the same node, that is MDS.
What's happen with my system, and how to fix it???
Help me, please!
Thanks,
