ZFS Server Error

[church117]

I work for a university and they have Three zfs servers running the latest Oracle os and sharing there file systems via napp-it application. Me and a colleague have been trying to share volumes between all three for redundancy. we keep getting a weird error "Sorry, your zfs is too old for zrep to handle volume initialization Error: Please initialize volume target by hand, if you won't upgrade" after typing in the command "zrep -i z0pool/test-lun (IPADDRESS) zpool"

I am leaving out the machines IP address for security purposes. But please if anyone has any ideas on how to fix this issue please let me know!

Oracle is of no help to a university IT department?

Two thoughts: as you update/upgrade the oracle servers, have you been upgrading the pool’s versions? This isn’t automatic, in case one server is more up to date than others, and if that one server fails and was using newer ZFS features then you wouldn’t be able to bring up the pool on another server. You should make sure all the servers have the same package/os versions, and do the pool upgrades on all at the same time https://docs.oracle.com/cd/E19253-01/819-5461/gcikw/index.html

 

The second thought is, you can always do it manually like the error says. Consult the manual.

Thank you I didn't of that, I thought if one thing got updated they all got updated.

I'd check to make sure that the latest kernel version for all OS' is the same. Just because theyve all been upgraded, doesn't mean the latest kernel is loaded.

Also check the zpool version
