[zfs-discuss] Removing disk from un-mirrrored pool - Status of development?
heya, I was wondering what's the status on the ability to remove disks from a ZFS pool? It's mentioned in the ZFS faq, as coming soon, and the BigAdmin Xperts page on ZFS mentions it as coming out in 2007. I know this is also discussed elsewhere, e.g.: http://www.opensolaris.org/jive/thread.jspa?messageID=314684#314684 but that focuses mainly on raid-z. However, what about the simple case, of an unmirrored pool? (e.g. a pool containing a 100gb and 250gb disk, for 350gb of storage, with usage around 20gb). Are there any plans to add the ability to remove one of the disks from the pool? Is it being developed at all? Or is there some hacky workaround to achieve this?

[zfs-discuss] Time-slider - zfs auto-snapshot services transition to maintenance?
heya, I'm using OpenSolaris 2008.11 (101a), and trying to use the time-slider functionality. The SUNWgnoem-time-slider and SUNWzfs-auto-snapshot packages enabled, and I've enabled time-slider via System, Administration, Time-Slider Setup. However, the auto-snapshot services appear to go into maintenance when they try to make their snapshots, and the time-slider service then goes into offline. I've included some log output below, which should hopefully provided some more info.
