I have been asked about this scenario, with a "roll their own" failover
scenario. S10u5 -- I think, at least 127127-11 kernel patch). 0
They have shared storage setup (a shared 3510) with ZFS, and when trying
to failover they run (aside from migrating the server's IP):
server1 (failing): unshare /mypool
zfs export /mypool
node2 (newly online): zfs import /mypool
share /mypool
After that the unsuspecting client gets nothing but ESTALE errors when
trying to read/write previously open files.
Is this something that should work? I suspect this might be due to
the fact that zfs_vfsinit() is finding a different major number for the
storage device on the two different nodes. Assuming the major number
is the same on both systems...is this something that should work?
Any guidance much appreciated - thanks! I guess this is more of a ZFS
question..
