Folks, I am learning more about zfs storage. It appears, zfs pool can be created on a raw disk. There is no need to create any partitions, etc. on the disk. Does this mean there is no need to run "format" on a raw disk? I have added a new disk to my system. It shows up as /dev/rdsk/c8t1d0s0. Do I need to format it before I convert it to zfs storage? Or, can I simply use it as: # zfs create MyData /dev/rdsk/c8t1d0s0 Thank you in advance for your help. Regards, Peter -- This message posted from opensolaris.org

I created a zfs pool with dedup with the following settings: zpool create data c8t1d0 zfs create data/shared zfs set dedup=on data/shared The thing I was wondering about was it seems like ZFS only dedup at the file level and not the block. When I make multiple copies of a file to the store I see an increase in the deup ratio, but when I copy similar files the ratio stays at 1.00x....

I am curious why zpool status reports a pool to be in the DEGRADED state after a drive in a raidz2 vdev has been successfully replaced. In this particular case drive c0t6d0 was failing so I ran, zpool offline home/c0t6d0 zpool replace home c0t6d0 c8t1d0 and after the resilvering finished the pool reports a degraded state. Hopefully this is incorrect. At this point is the vdev in question now has full raidz2 protected even though it is listed as "DEGRADED"? P.S. This is on a pool created on S10U3 and upgraded to ZFS version 4 after upgr...

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 as it dies (and now preemptively removing disks.) My complaint is that resilvering ends up

Hello, I have a dual boot with Windows 7 64 bit enterprise edition and Opensolaris build 134. This is on Sun Ultra 40 M1 workstation. Three hard drives, 2 in ZFS mirror, 1 is shared with Windows. Last 2 days I was working in Windows. I didn''t touch the hard drives in any way except I once opened Disk Management to figure out why a external USB hard drive is not being listed.

Hi all I''m seeing some rather bad resilver times for a pool of WD Green drives (I know, bad drives, but leave that). Does resilver go through the whole pool or just the VDEV in question? -- Vennlige hilsener / Best regards roy -- Roy Sigurd Karlsbakk (+47) 97542685 roy at karlsbakk.net http://blogg.karlsbakk.net/ -- I all pedagogikk er det essensielt at pensum presenteres
