Hi,
Trying to start MDS/MDT and OST on the same node ...
MDS /MDT combo appears to be working fine ...
[EMAIL PROTECTED] ~]# cat /proc/fs/lustre/devices
0 UP mgs MGS MGS 5
1 UP mgc [EMAIL PROTECTED] 3c892ff4-3c64-c307-517e-f0d06ecfde8d 5
2 UP mdt MDS MDS_uuid 3
3 UP lov testfs-mdtlov testfs-mdtlov_UUID 4
4 UP mds testfs-MDT0000 testfs-MDT0000_UUID 3

Has anyone run into or had experience with this issue? OST won't start for me
in 1.5.97.
[EMAIL PROTECTED] ~]# mkfs.lustre --reformat --fsname=testfs --ost [EMAIL

This may have multiple causes.
Are the mount options correct?
Check the syslog for more info.
