I don't know how relevant this is to you on Nexenta, but I can tell you that the driver support for that card improved tremendously with OpenSolaris 2008.11. All of our hot swap problems went away with that release but the change wasn't documented anywhere that I could see. It might be worth

Re: [zfs-discuss] Very slow ZFS write speed to raw zvol

Thanks for the great tips. I did some more testing and indeed it was a version issue. The pool was created under: # zpool upgrade This system is currently running ZFS version 14. whereas I tried it on systems with versions 10 and 12. It could be imported on a newer system using -f option. I

[zfs-discuss] Slow Resilvering Performance

2009-07-10 Thread Galen
I know this topic has been discussed many times... but what the hell makes zpool resilvering so slow? I'm running OpenSolaris 2009.06. I have had a large number of problematic disks due to a bad production batch, leading me to resilver quite a few times, progressively replacing each disk
