export and apply zpool configuration

Rowley · 07-04-2011, 07:39 AM

I have two hosts each with 50 disks.

I configure various zpool's on host A just as I want them. I then want to take these zpool configurations and apply it to identical hardware on host B.

Anyone know if this can be done? If so how?

Why dont you just copy the same commands? There is "zpool history" or something similar which shows every command you have used on host A. Take these commands and apply them to host B.

Thanks for taking the time to reply.

I could "copy" the commands but, there is always the very real risk when copying stuff from a terminal that mistakes will be made, particularly when dealing with hundreds of devices and file systems.

Veritas Volume Manager allows you to take whole disk groups and their volume configuration and apply that to another set of disks. I'm surprised that when the developers as Sun decided to write ZFS and its tool set, they didn't pick up that this might be something that many of their customers might want to make use of.

Probably they (at SUN) had more reliable terminals then You have

Export it to a text file, edit it and then apply the text file?

I dont know of any way of doing automated zfs things.

But, when you create 100s of zfs filesystems, then you just send them to host B. There is no need to create every filesystem on host B. If you send the filesystems to host B, they will be created and copied to host B.
