Dear All:
I map the same rbd image to the rbd device on two different servers.
For example:
1. create rbd image named foo
2. map foo to /dev/rbd0 on server A, mount /dev/rbd0 to /mnt
3. map foo to /dev/rbd0 on server B, mount /dev/rbd0 to /mnt
If I put add a file to /mnt via server A, I hope I can see the same
file on server B.
However, I can't see it until I umount /mnt on server A and re-mount
/mnt on server B.
Do you have any comment about this scenario? How could I force the
data synchronization?
Actually, I want to implement the iSCSI High Available multipath on
http://ceph.newdream.net/wiki/ISCSI.
Therefore, I tried this small experiment first, but fail. Would you
please give me some suggestion before I start to implement it? Thanks!
