Description
I tried this test on current master.
MDT1
[root@client-2 ~]# mkfs.lustre --reformat --mgs --mdt --index=0 --fsname lustre --failnode=10.10.4.3@tcp /dev/disk/by-id/scsi-1IET_00040001
MDT2
[root@client-3 ~]# mkfs.lustre --reformat --mgsnode=10.10.4.2@tcp --mgsnode=10.10.4.3@tcp --mdt --index=1 --fsname lustre --failnode=10.10.4.2@tcp /dev/disk/by-id/scsi-1IET_00020001
But unfortunately when it failed when I tries to mount mdt2
