hi all,
(pls keep me in cc, i'm not subscribed to this list)
i am trying out the replicas feature of exportfs, but i'm unable to get
it working.
i would like to know if what i'm trying to is actually implemented in
linux (or intended behaviour of replicas in the first place).
2 nfs4 servers with cluster filesystem (gpfs in my case). the os is
sl6.4, i've enabled the nfs version 4.1 on the server (from my
understanding, 4.0 should be enough?).
i would like to test if the replicas features can be used for failover
support of a rw nfs export. ie
a. mount nfs from server1 on client
b. start some IO activity on client on the mounted filesystem
c. poweroff server1
d. after a certain amount of time, IO continues using server2
(the client i'm testing with is also el6.4 atm.)
many thanks,
stijn

No, the client has no support I'm aware of for failover to replicas.
