[Lustre-discuss] Lustre mount problem

[Frank Mietke]

Hi,

we're using 1.6.4.2 here. 5 days ago we lost an OST block device forever. I
deactivated this OST, recreated the block device and started "mkfs.lustre --reformat ..." on this
device and gave it the same OST id (OST0010)  as before. A mount of this OST went wrong
with the "already in use" message. Therefore I reformatted the device again with
no index number passed. But now, when I try to mount the clients I've got the
following in dmesg:

Lustre: 1837:0:(obd_mount.c:1685:lustre_check_exclusion()) Excluding

Any hints are appreciated. Is there a way to fully remove the OST0010 from the
configuration?

Thanks,
Frank
