Have you considered moving to 10/08 ? ZFS resilver performance is much improved in this release, and I suspect that code might help you. You can easily test upgrading with Live Upgrade. I did the transition using LU and was very happy with the results. For example, I added a disk to a mirror an

It completed copying 191,xxx MB without issue in 17 hours and 40 minutes, average transfer rate of 3.0MB/Sec. During the copy (At least the first hour or so, and an hour in the middle), the machine was reasonably responsive. It was jerky to a greater or lesser extent, but nothing like even the

Re: [zfs-discuss] Gnome Disk Usage Analyzer

Hmm, there appear to be a few bugs with it actually. In addition to locking up the system while scanning, it seems to have created a circular reference. It looks like it hasn't been able to finish scanning the folders, and has wound up creating a link back to the ZFS root with the last folder

Aaah, nm, found it. It's under a different menu in OpenSolaris, and looks like it scans ZFS fine. There doesn't appear to be any way to stop a scan once you've started it though, the entire GUI looks to have frozen up on me. -- This message posted from opensolaris.org _

Could zfs be configured to use gzip-9 to compress small files or when the system is idle.. When the system is busy or is handling a large file use lzjb. Busy/Idle and large/small files would need to be defined somewhere. Alternatively, write the file out using lzjb if the system is busy and go
