[Lustre-discuss] Question about failnode

[Kazuki Ohara]

Hi,
I have a question about the fainode directive of mkfs.lustre.
I hope someone help me.

When a shared volume is formatted and mounted as below,
  [root at ossnode1 ~]# mkfs.lustre --ost --failnode=ossnode2 \
  > --mgsnode=mgsnode at tcp /dev/sda1
  [root at ossnode1 ~]# mount -t lustre /dev/sda1 /mnt/ost1
ossnode1 knows that sda1 can be accessed by ossnode2.

Then, a failover occurs and ossnode2 mounts sda1,
I think there is no way for ossnode2 to know sda1 can be accessed by ossnode1.
Does this become a problem?

Best regards,
Kazuki Ohara
