Hello all. I am working on an NFS failover scenario between two servers. I am getting the stale file handle errors on my (linux) client which point to there being a mismatch in the fsid's of my two filesystems when the failover occurs. I understand that the fsid_guid attribute which is then

Hi all, I am currently planning a new home file server on a gigabit network that will be utilizing ZFS (on SXDE). The files will be shared via samba as I have a mixed OS environment. The controller card I will be using is the SuperMicro SAT2-MV8 133MHz PCI-X card. I have two options for CPUs
