Hello I have a 3 node cluster with an identical zfs pool on each. I have successfully setup a replication job for my vm.

This is a windows vm that has 2 scsi disks on it. The 1st disk has the system with programs and data. The 2nd disk is only used for the page file. I would like to skip the replication of the 2nd disk.

If I do this I'm not sure how I would fail it over to one of the other nodes. I realize I would either need to have a copy of the drive from primary node or I'd have to create it on the other node.
 
Check the settings for the disk/mount, there's a Skip replication option. You might need to enable Advanced to see it.

As @Impact said, use "Skip replication". But you should create the disk on the other nodes. Maybe the simpler is to replicate one time and disable replication after. And test, test, test :-)
 
Thanks for the info I have checked the skip replication after the initial replication was done and after the next replication it removed the disk from the other nodes. It seems that this configuration is not easy to do. It's unfortunate since I believe it would really cut down on unnecessary replication tasks for the zfs pool etc. Has anyone successfully done this before in proxmox?

Ok. Maybe it could cut down replication. But pagefile shouldn't be used too much if you system is well dimensioned at RAM level I think.
