I have added 2 volumes onto my existing filesystem.
mkfs.lustre --fsname lfs002 --ost --mgsnode=mg...@tcp /dev/lustrevg/lv03
mkfs.lustre --fsname lfs002 --ost --mgsnode=mg...@tcp /dev/lustrevg/lv04
I even managed to mount up the OSTS (each are 2TB)
However, on the clients we don't see the extra 4TB.
I am not sure whats going on.
On the OST:
I can see the new OSTs mounted up properly
/proc/fs/lustre/obdfilter/lfs002* I see the mounted filesystem device
on mntdev in the /proc/filesystem
I even managed to reboot the MDS and OSS and the clients still no go.
I **think** on my MDS I see the new OSS too, just not on the clients.
Is there anything I should be looking at?
first, tunefs.lustre --print on the OST to be certain you have the
fsname set correctly ( i think it needs to be --fsname= )
Second, 'lctl dl' on the MDS should show you a connection to the new
OSTs. If not, the MGS hasn't registered them with this filesystem.
# lctl dl
3 UP mds test1-MDT test1-MDT_UUID 5
...
5 UP osc test1-OST0001-osc test1-mdtlov_UUID 5
'lctl dl' on the OST should show an MGC connection
# lctl dl
0 UP mgc mgc10.67.73@tcp 92778f8e-f7e6-0327-e433-63d230eea1a9 5
1 UP ost OSS OSS_uuid 3
2 UP obdfilter test1-OST0001 test1-OST0001_UUID 7
Check the OST log, there should be a 'recieved MDS connection from'
message if you were registered correctly.
/var/log/messages.2:Mar 2 11:17:24 d1c2 kernel: Lustre: test1-OST0001:
received MDS connection from 10.67.73@tcp
New OSTs should be automatically recognized by the clients, and 'lctl
dl' on the clients should show the new OSTs.
