similar to: ZFS Filesystem Recovery on RAIDZ Array

I have a customer who has implemented the following layout: As you can see, he has mostly raidz zvols but has one raidz2 in the same zpool. What are the implications here? Is this a bad thing to do? Please elaborate. Thanks, Scott Gaspard Scott.J.Gaspard at Sun.COM > NAME STATE READ WRITE CKSUM > > chipool1 ONLINE 0 0 0 > >

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

Will it be possible to update an existing raidz to a raidz2? I wouldn''t think so, but maybe I''ll be pleasantly surprised. -frank

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 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

Had an idea, could someone please tell me why it''s wrong? (I feel like it has to be). A RaidZ-2 pool with one missing disk offers the same failure resilience as a healthy RaidZ1 pool (no data loss when one disk fails). I had initially wanted to do single parity raidz pool (5disk), but after a recent scare decided raidz2 was the way to go. With the help of a sparse file

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

<http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide#RAID-Z_Configuration_Requirements_and_Recommendations> says that the number of disks in a RAIDZ should be (N+P) with N = {2,4,8} and P = {1,2}. But if you go down the page just a little further to the thumper configuration examples, none of the 3 examples follow this recommendation! I will have 10 disks to put into a

Hi all, I have 2 questions about ZFS. 1. I have create a snapshot in my pool1/data1, and zfs send/recv it to pool2/data2. but I found the USED in zfs list is different: NAME USED AVAIL REFER MOUNTPOINT pool2/data2 160G 1.44T 159G /pool2/data2 pool1/data 176G 638G 175G /pool1/data1 It keep about 30,000,000 files. The content of p_pool/p1 and backup/p_backup

Already making use of it, thank you! http://www.justinconover.com/blog/?p=17 I took 6x250gb disk and tried raidz2/raidz/none # zpool create zfs raidz2 c0d0 c1d0 c2d0 c3d0 c7d0 c8d0 df -h zfs Filesystem size used avail capacity Mounted on zfs 915G 49K 915G 1% /zfs # zpool destroy -f zfs Plain old raidz (raid-5ish) # zpool create zfs raidz c0d0

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.

I''m working to expand / develop on the zpool built-in type, but the zpool command is failing and Puppet''s returned stderr is not what I get if I copy/paste the command given by the debug output. # cat /etc/puppet/manifests/zpool_raidz2.pp zpool { ''tank'': ensure => present, raidz => [ ''d01 d02 d03 d04'', ''d05 d06

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

Hello to the forum, with my general question about ZFS and RAIDZ I want the following to know: Must all harddisks for the storage pool have the same capacity or is it possible to use harddisks with different capacities? Many thanks for the answers. Best regards JueDan -- This message posted from opensolaris.org

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)

Hi, Well I have a freshly built system with ZFS raidz. Intel P4 2.4 Ghz 1GB Ram Marvell Technology Group Ltd. MV88SX6081 8-port SATA II PCI-X Controller (2) Intel Dual Port 1Gbit nics I have (5) 300GB disks in a Raidz1 with Zfs. I''ve created a couple of FS on this. /export/downloads /export/music /export/musicraw I''ve shared these out as well. First with ZFS ''zfs

Hi zfsers Just wanted to ping the list since one of the osunix/grub devs has been working hard at porting zfs to grub2. I don''t think he''s subscribed to zfs-discuss so quoting his original email and cc''ing him. Drop by #osunix on freenode if you''re interested in the raidz/compressed rpool support

Hi all, I have been looking at various alternatives for a system that runs several Linux & Windows guests. So far my favorite choice would be OpenSolaris+ZFS+RAIDZ+VirtualBox. Is this combo ready to be a host for Linux & Windows guests? Or is it not 100% stable (yet)? Greetings, Evert This message posted from opensolaris.org

Why does zfs define raidz/raidz2/mirror/stripe at the pool level instead of the filesystem/volume level? A sample use case: two filesystems in a eight disk pool. The first filesystems is a stripe across four mirrors. The second filesystems is a raidz2. Both utilizing the free space in the 8 disk pool as needed. Thanks in advance...
