[Lustre-discuss] More failover issues

[Robert LeBlanc]

This is what I'm getting:

head2-2:~# 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 /dev/mapper/ldiskd-part1

   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=192.168.1.253 at o2ib failover.node=192.168.1.252 at o2ib mdt.group_upcall=/usr/sbin/l_getgroups

device size = 972MB
formatting backing filesystem ldiskfs on /dev/mapper/ldiskd-part1
        target name  home-MDTffff
        4k blocks     0
        options       -O dir_index -i 4096 -I 512 -q -F
mkfs_cmd = mkfs.ext2 -j -b 4096 -L home-MDTffff -O dir_index -i 4096 -I 512 -q -F /dev/mapper/ldiskd-part1
Writing CONFIGS/mountdata


For some reason, only the last --mgsnode option is being kept.

Multiple --mgsnode parameters should work:
mkfs.lustre --mkfsoptions="-O dir_index" --reformat --mdt 
--mgsnode=192.168.1.253 at o2ib --mgsnode=1 at elan --device-size=10000 /tmp/foo
