I have added 2 volumes onto my existing filesystem. mkfs.lustre --fsname lfs002 --ost --mgsnode=mgs01 at tcp /dev/lustrevg/lv03 mkfs.lustre --fsname lfs002 --ost --mgsnode=mgs01 at 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? TIA

Thanks Cliff. Seems like when I used fsname= (with the equal) it worked.
