[Lustre-discuss] More failover issues

[Nathan Rutman]

Strangely, this works with my version of the 163 release branch, but 
doesn't work on my 164 prerelease (same prob as you).
Anyhow, try grabbing and older version of mkfs.lustre, from 1.6.0.1, 
1.6.1, or 1.6.2.  There's been no major changes.

cfs21:~/cfs/b_release_1_6_3/lustre/utils# ./mkfs.lustre
mkfs.lustre v1.6.3
cfs21:~/cfs/b_release_1_6_3/lustre/utils# ./mkfs.lustre 
--mkfsoptions="-O dir_index" --reformat --mdt --fsname=home 
--mgsnode=192.168.1.252 at o2ib --mgsnode=192.168.1.253 at o2ib 
--failnode=192.168.1.252 at o2ib --device-size=10000 /tmp/foo

   Permanent disk data:
Target:     home-MDTffff
Index:      unassigned
Lustre FS:  home
Mount type: ldiskfs
Flags:      0x71
              (MDT needs_index first_time update )
Persistent mount opts: errors=remount-ro,iopen_nopriv,user_xattr
Parameters: mgsnode=192.168.1.252 at o2ib mgsnode=192.168.1.253 at o2ib 
failover.node=192.168.1.252 at o2ib
