If you want both of the servers live at the same time, you need the content volume r/o to both systems, or a cluster file system, or to mount the content from a 3rd machine via NFS.
If you're OK with a single point of failure, you can set up one system as a NFS master and then mount the filesystem from the master on the other system. Naturally if the NFS server fails, you're SOL. You should also disable fsck on boot on the r/o system. > -----Original Message----- > From: Linux on 390 Port [mailto:[email protected]] On Behalf Of > Diep, David (OCTO-Contractor) > Sent: Wednesday, October 23, 2013 11:18 AM > To: [email protected] > Subject: Whats the best way to share z/VM Volumes between two Redhat > guest machines > > Hi, > > First time posting here...
