similar to: Mirror and RaidZ on only 3 disks

Hi, We have a number of 4200''s setup using a combination of an SVM 4 way mirror and a ZFS raidz stripe. Each disk (of 4) is divided up like this / 6GB UFS s0 Swap 8GB s1 /var 6GB UFS s3 Metadb 50MB UFS s4 /data 48GB ZFS s5 For SVM we do a 4 way mirror on /,swap, and /var So we have 3 SVM mirrors d0=root (sub mirrors d10, d20, d30, d40) d1=swap (sub mirrors d11, d21,d31,d41)

Hello to you all, Here''s the situation: While doing a case replacement in my home storage server I accidentally removed the post-it with the disk number from my three 1TB disks before connecting them back to the corresponding SATA connector. The issue now is that I don''t know in which order they should be connected. Do any of you know how can I _safely_ bring the zpool

So, I took four 1.5TB drives and made RAIDZ, RAIDZ1 and RAIDZ2 pools. The sizes for the pools were 5.3TB, 4.0TB, and 2.67TB respectively. The man page for RAIDZ states that "The raidz vdev type is an alias for raidz1." So why was there a difference between the sizes for RAIDZ and RAIDZ1? Shouldn''t the size be the same for "zpool create raidz ..." and "zpool

Hi Is it possible to convert live 3 disks zpool from raidz to raidz2 And is it possible to add 1 new disk to raidz configuration without backups and recreating zpool from cratch. Thanks This message posted from opensolaris.org

I am converting a 4 disk raidz from osx to opensolaris. And I want to keep the data intact. I want zfs to get access to the full disk instead of a slice. I believe like c8d0 instead off c8d0s1. I wanted to do this 1 disk at a time and let it resilver. what is the proper way to do this. I tried, I believe from memory : zpool replace -f rpool c8d1s1 c8d1 but it didn''t let me do that. then I

Hi all, Sorry for the newbie question, but I''ve looked at the docs and haven''t been able to find an answer for this. I''m working with a system where the pool has already been configured and want to determine what the configuration is. I had thought that''d be with zpool status -v <poolname>, but it doesn''t seem to agree with the

Hi all, Please can you help with my ZFS troubles: I currently have 3 x 400 GB Seagate NL35''s and a 500 GB Samsung Spinpoint in a RAIDZ array that I wish to expand by systematically replacing each drive with a 750 GB Western Digital Caviar. After failing miserably, I''d like to start from scratch again if possible. When I last tried, the replace command hung for an age, network

Hello All, I have a zpool that consists of 2 raidz vdevs (raidz1-0 and raidz1-1). The first vdev is 4 1.5TB drives. The second was 4 500GB drives. I replaced the 4 500GB drives with 4 3TB drives. I replaced one at time, and resilvered each. Now the process is complete, I expected to have an extra 10TB (4*2.5TB) of raw space, but it''s still the same amount of space. I did an export and

Hi all, I currently have four drives in my OpenSolaris box. The drives are split into two mirrors, one mirror containing my rpool (disks 1 & 2) and one containing other data (disks 2 & 3). I''m running out of space on my data mirror and am thinking of upgrading it to two 2TB disks. I then considered replacing disk 2 with a 2TB disk and making a RAIDz from the three new drives.

Hello everyone, As one of the steps of improving my ZFS home fileserver (snv_134) I wanted to replace a 1TB disk with a newer one of the same vendor/model/size because this new one has 64MB cache vs. 16MB in the previous one. The removed disk will be use for backups, so I thought it''s better off to have a 64MB cache disk in the on-line pool than in the backup set sitting off-line all

Hi, I installed a zpool containing of zpool __mirror ____disk1 500gb ____disk2 500gb __raidz ____disk3 1tb ____disk4 1tb ____disk5 1tb It works fine, but it displays the wrong size (terminal -> zpool list). It should be 500gb (mirrored) + 2TB (3TB raidz) = 2,5 TB, right? But it displays it has 3,17TB diskspace available. I first created the mirror and then added the raidz to it (zpool add

I skimmed the archives and found a thread from July earlier this year about RAIDZ expansion. Not adding more RAIDZ stripes to a pool, but adding more drives to the stripe itself. I''m wondering if an RFE has been submitted for this and if any progress has been made, or is expected? I find myself out of space on my current RAID5 setup and would love to flip over to a ZFS raidz2 solution

Hi there, i''m building a small NAS with 5x1TB Disks. The disks contains at the moment some data, ntfs as the fs and aren''t a raid. Now my im wondering if its possible to add the parity later. So that i add step by step one disk to the pool. And when i add the last disk, i enable the parity. (i have only one another 1 tb disk to backup the files) Thank you for you replies and

Hi, I''m completely new to Solaris, but have managed to bumble through installing it to a single disk, creating an additional 3 disk RAIDZ array and then copying over data from a separate NTFS formatted disk onto the array using NTFS-3G. However, the single disk that was used for the OS installation has since died (it was very old) and I have had to reinstall 2008.11 from scratch onto a

Hi All, I had a slice with zfs file system which I want to mirror, I followed the procedure mentioned in the amin guide I am getting this error. Can you tell me what I did wrong? root # zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT export 254G 230K 254G 0% ONLINE - root # echo |format Searching for disks...done

Yeah:) I''d like to work on this. Here are my first observations: - We need to call vdev_op_asize method with additonal ''offset'' argument, - We need to move data to new disk starting from the very begining, so we can''t reuse scrub/resilver code which does tree-walk through the data. Below you can see how I imagine to extend RAIDZ. Here is the legend:

Hi all, I have a 5 drive RAIDZ volume with data that I''d like to recover. The long story runs roughly: 1) The volume was running fine under FreeBSD on motherboard SATA controllers. 2) Two drives were moved to a HP P411 SAS/SATA controller 3) I *think* the HP controllers wrote some volume information to the end of each disk (hence no more ZFS labels 2,3) 4) In its "auto

Hi all :) I''ve been wanting to make the switch from XFS over RAID5 to ZFS/RAIDZ2 for some time now, ever since I read about ZFS the first time. Absolutely amazing beast! I''ve built my own little hobby server at home and have a boatload of disks in different sizes that I''ve been using together to build a RAID5 array on Linux using mdadm in two layers; first layer is

Hello, I was hoping that this would work: http://blogs.sun.com/zhangfan/entry/how_to_turn_a_mirror I have 4x(1TB) disks, one of which is filled with 800GB of data (that I cant delete/backup somewhere else) > root at FSK-Backup:~# zpool create -f ambry raidz1 c4t0d0 c5t0d0 c5t1d0 > /dev/lofi/1 > root at FSK-Backup:~# zpool list > NAME SIZE USED AVAIL CAP HEALTH ALTROOT
