I have inherited the following setup.
2 Linux servers running NFS in an active / standby configuration with heartbeat software
to manage the failover.
DrDB mirroring the data from one server to the other.
I would like to move to using a fibre-SAN (already available for other reasons).
So my questions are.
1) What is the recommended storage configuration – ‘shared storage’ between the servers
- no DrDB ?
2) How do you manage the file system across the 2 servers ?
Do you need to worry about mounting / dismounting the file system on the active / standby
Thanks for any help.
Note: I am a novice when it comes to NFS / SAN technology.
