# zpool upgrade
This system is currently running ZFS pool version 10.
All pools are formatted using this version.

# zfs upgrade
This system is currently running ZFS filesystem version 3.

The following filesystems are out of date, and can be upgraded. After being
upgraded, these filesystems (and any 'zfs send' streams generated from
subsequent snapshots) will no longer be accessible by older software versions.

VER FILESYSTEM
--- ------------
1 sybdump

I think the easiest solution (not requiring system upgrade) is to add new LUN to the system and add it to the pool with the "zpool add" command. I don't know if it is safe to shrink existing LUN to the old (500GB) size... so you might have wasted 100GB of space.

Thanks for your assistance. If thats what the solution is, then I will need to find out how to do that.

There is also one more possibility. But it requires unmounting of the filesystems and might not even work. You might try doing export/import of the pool with:

Code:

zpool export sybdump
zpool import sybdump

Filesystems will be mounted automatically after the import. Let me know if you tried it and if it helped.

It should just work but will require to stop all applications using the affected file systems and volumes, possibly by going in single user mode.

Exporting/importing was the way to have pools taking into account LUN enlargements before "zpool online -e" and the "autoexpand" property were implemented with Solaris 10 09/10.

Bart -

Thanks for the info, and sorry I haven't responded sooner. I will try that and see if it works, and then let you know.

Thanks.
