How can you nfs mount a directory exported by a cluster service that is
currently local to the cluster member?
I have a two-member Red Hat HA cluster with hostnames arned and nihal and
cluster services lepusbb and lepustl.
When service lepusbb runs on arneb, I cannot nfs mount its device on arneb
using the service name. I.e.
# mount -t nfs lepusbb:/usr/local/lepus-bb /usr/local/bb
does not work on arneb, but it does work on nihal.
Similarly, when lepustl is running on nihal, I can mount
lepustl:/usr/local/lepus-tl on arneb but not on nihal.
I can mount the service locally using the hostname:
# mount -t nfs arneb:/usr/local/lepus-bb /usr/local/bb
so I'm currently using that as a workaround, but obviously,
when a failover would occur while the devices are locally mounted in this
way, my
scripts wil be in trouble.
Portmapper and nfslock are running. I stopped the firewall on both
systems to make sure it isn't part of the problem. I also tried exporting
to all hosts ("*"), all to no avail.
Kind regards,
emma
P.S. If there's a more appropriate place to address this issue, I'd
appreciate a pointer.
