Hi all,

I have a really odd issue, only 1 OST appears to mount despite there being
4 OSTS available and ACTIVE.

[root at hpc-login-01 home]# lfs df -h
UUID                       bytes        Used   Available Use% Mounted on
home-MDT0000_UUID           4.2T       40.2G        4.1T   1% /home[MDT:0]
home-OST0000_UUID          47.6T       37.8T        9.8T  80% /home[OST:0]
home-OST0001_UUID          47.6T       47.2T      413.4G 100% /home[OST:1] D
home-OST0002_UUID          47.6T       35.7T       11.9T  75% /home[OST:2]
home-OST0003_UUID          47.6T       39.4T        8.2T  83% /home[OST:3]

filesystem_summary:       190.4T      160.0T       30.3T  85% /home

[root at hpc-login-01 home]# lfs check osts
home-OST0000-osc-ffffa10c8f483800 active.
home-OST0001-osc-ffffa10c8f483800 active.
home-OST0002-osc-ffffa10c8f483800 active.
home-OST0003-osc-ffffa10c8f483800 active.

Should be 191TB... only shows 1 OST.. at o2ib:/home     *48T *  48T  414G 100% /home

Where should I look?
