Re: [zfs-discuss] resilver = defrag?
I am not really worried about fragmentation. I was just wondering if I attach new drives and zfs send recieve to a new zpool, would count as defrag. But apparently, not. Anyway thank you for your input! -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] resilver = defrag?
It really depends on your definition of fragmentation. This term is used differently for various file systems. The UFS notion of fragmentation is closer to the ZFS notion of gangs. -- richard On Sep 11, 2010, at 6:16 AM, Orvar Korvar knatte_fnatte_tja...@yahoo.com wrote: I am not really worried about fragmentation.

[zfs-discuss] ZFS online device management
Hello, I found in the release notes for Solaris 10 9/10: Oracle Solaris ZFS online device management, which allows customers to make changes to filesystem configurations, without taking data offline. Can somebody kindly clarify what sort of filesystem configuration changes can me made this way? Does this include, say, changing a 6 disk RAID-Z to two 3 disk RAID-Z sets striped? -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

See below.

sets striped?
Nope.
You can add/remove mirrors of disks online (assuming you start with a
non-raidz vdev).
You can expand a pool by adding more vdevs.
You can not transform a raidz from one form to another.
You can not remove a vdev.
