[lustre-discuss] ost doesn't mount

Thu May 11 02:19:05 PDT 2017

To answer my own question:

# tunefs.lustre --mountfsoptions=" ,errors=remount-ro" /dev/dm-2

# tunefs.lustre --print /dev/dm-2
checking for existing Lustre data: found
Reading CONFIGS/mountdata

   Read previous values:
Target:     umcgst08-OST0002
Index:      2
Lustre FS:  umcgst08
Mount type: ldiskfs
Flags:      0x2
              (OST )
Persistent mount opts: errors=remount-ro
Parameters:  mgsnode=172.23.34.214 at tcp:172.23.34.213 at tcp

   Permanent disk data:
Target:     umcgst08-OST0002
Index:      2
Lustre FS:  umcgst08
Mount type: ldiskfs
Flags:      0x2
              (OST )
Persistent mount opts: errors=remount-ro
Parameters:  mgsnode=172.23.34.214 at tcp:172.23.34.213 at tcp

volumes are now able to mount, with SElinux disabled!
