This is a small development system with a combined MDS/MGS on a single node with
a SCSI interface to a disk array. There are two OSSes, each with a single OST
of 1.4TB comprised of a SATA array. In all cases, the entire device (/dev/sdc)
is used with no partitioning.
I upgraded my Lustre MDS and OSS servers from 1.6.6 to 1.8.3. I did this via a
complete OS install and then performing a writeconf on each of the nodes.
Unfortunately, each of the OSSes thinks it's Lustre "Target" is
"lustre1-OST0000". I've mounted the partitions via ldiskfs and the underlying
data is still there. I know which OSS is supposed to be "lustre1-OST0001", but
I can't find any docs that explain how to set that.
Thanks,
Roger S.
