Re: [zfs-discuss] Raidz2 slow read speed (under 5MB/s)

Nevermind this, I destroyed the raid volume, then checked each hard drive one by one, and when I put it back together, the problem fixed itself. I'm now getting 30-60MB/s read and write, which is still slow as heck, but works well for my application. -- This message posted from opensolaris.org

[zfs-discuss] Migrating from ZFS-Fuse to ZFS Proper...

2011-07-22 Thread Tiernan OToole
Good morning all. I built a test system using Linux (Ubuntu) and ZFS Fuse, just for testing... I formatted 2 drives in the pool as ZFS, and have been putting data on the system to see how performance worked, etc... Is this pool compatible with ZFS proper? Eg, Solaris Express? Open Indiana?, or Nex

[zfs-discuss] Replacing failed drive

2011-07-22 Thread Chris Dunbar - Earthside, LLC
Hello, The bad news is I lost a drive on my production server. The good news is the spare kicked in and everything kept running as it should. I stopped by the datacenter last night, shut down the server, and physically replaced the failed drive. I want to make sure I don't screw anything up so

Hi Chris, Which Solaris release is this? Depending on the Solaris release, you have a couple of different options. Here's one: 1. Physically replace original failed disk and detach the spare. A. If c10t0d0 was the disk that you physically replaced, issue this command: # zpool replace tank c

Cindy, Thank you for the reply. I am running Solaris Express 11 (5.11 snv_151a i86pc i386 i86pc Solaris). I have physically replaced the drive, but I have not partitioned it yet. I know there is a command to copy the layout from one disk to another and that has worked well for me in the pa

Chris, You don't need to partition the drive because your pool contains whole disks. The zpool replace command will do any relabeling that is needed. Do the replace first and then detach the spare, if needed. The spare should detach automatically but sometimes it doesn't. Thanks, Cindy On 0
