hi everyone,
I am planning on creating a local SAN via NFS(v4) and several redundant
nodes.
I have been using DRBD on linux before and now am asking whether some of
you have experience on on-demand network filesystem mirrors.
I have yet little Solaris sysadmin know how, but i am interesting
whether there is an on-demand support for sending snapshots. I.e. not
via a cron job, but via a kind of filesystem change notification system.
Is this mere a hack or can it be used to create some sort of failover.
E.g. DRBD has the master/slave option, which can be configured easily.
Something like this would be nice out of the box. So in case of failure
another node is the master and if the former master is back again, it is
simply the slave, so that both have the current data available again.
Any pointers to solutions in that area are greatly appreaciated.
