Hello,
I suspect that I'm doing something fairly stupid, but I'm having a
problem with a cluster that is exporting the same GFS filesystems to
the same nfs clients. Everything thing is fine until I relocate one
of the nfs services to another machine. The relocation goes fine, but
once I have two nfs services on the same machine, I can't get them
apart. When I relocate one of the two nfs services to a different
cluster host, the relocation wipes out the entries in
/var/lib/nfs/etab, forcing the second nfs service on that node to
relocate as well (I get the error "nfsclient:rc_nfs_clients is
missing!").
Any suggestions? Other than modifying
/usr/share/cluster/nfsclient.sh, is there some way to prevent the etab
entries from being purged?
Thanks!
Chris
