checking zpool version

[gearhead]

I am trying to see what zpool version I have. So I use the command line # zpool upgrade -v, however the problem is that the version number is on the first line of the output and it scroll by quickly that I can't see the first line. I have set the shell size to 132x50 and I am using Opera as browser. So is there a way to have the screen output pause? or is there a way to make shell size bigger than 132x50? TIA

I think zpool status <poolname> gives you this info..

Is zpool upgrade <poolname> not the command to upgrade? Are you sure you want to do this?

Adding |more to the end of any command should page long output (it doesn't always in Shell but always does over an ssh session).

I think zpool status <poolname> gives you this info..

"zpool get version <pool>" is the correct command. You will either get the pool version or a dash (-). In that case your pool is using feature flags (pool version "5000") and you can run "zpool get all <pool> | grep feature@" to get the list of supported/enabled features.

Thanks everybody. I still can not get a version number. The following link from Oracle explains how to check to version number.

Below is a screen shot which I wanted ti include with the previous post.

[root@freenas ~]# zpool status Data pool: Data state: ONLINE status: The pool is formatted using a legacy on-disk format. The pool can still be used, but some features are unavailable. action: Upgrade the pool using 'zpool upgrade'. Once this is done, the pool will no longer be accessible on software that does not support feature flags. scan: scrub repaired 0 in 3h21m with 0 errors on Sun Dec 15 16:44:43 2013 config: NAME STATE READ WRITE CKSUM Data ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 gptid/cd17218b-a966-11e2-ad8d-d43d7e18b257 ONLINE 0 0 0 gptid/8eb3224b-12af-11e3-89c0-d43d7e18b257 ONLINE 0 0 0 errors: No known data errors [root@freenas ~]#

Maybe third attempt is the charm.

Use the syntax Dusan gave you. He's an expert.
