[lustre-discuss] Lustre 2.10.4 failover

[David Cohen]

the fstab line I use for mounting the Lustre filesystem:

oss03 at tcp:oss01 at tcp:/fsname /storage        lustre
flock,user_xattr,defaults    0 0

the mds is also configured for failover (unsuccessfully) :
tunefs.lustre --writeconf --erase-params --fsname=fsname --mgs
--mountfsoptions='user_xattr,errors=remount-ro,acl'
--param="mgsnode=oss03 at tcp mgsnode=oss01 at tcp servicenode=oss01 at tcp
servicenode=oss03 at tcp" /dev/lustre_pool/MDT
