similar to: raidz question

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, 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 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

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

Greetings Have used zfs raidz for while and question rised is it possible to expand raidz with additional disks. Got answer pool yes but raidz "group" no. So very high level idea for you , maybe already know. And i''m not detail level expert of zfs so here might be "trivial" things for you. So could add operation enhanced so that it allow to add additional

<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, 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

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.

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

1. I have a 4x18GB drive setup as RAIDZ. Now when thinking about it in terms of RAID5 I would expect to get (4-1)x18 worth of drive space, but DF -h shows 4x18. Is this a bug or do I not understand? 2. Once again thinking in RAID5 terms if I have 4X18GB and 12X9GB drives and I want to make a RAIDZ of all of them I would expect the 18GB to be treated at 9GB so the RAIDZ would be 16X9GB. Is

I made a bad judgment and now my raidz pool is corrupted. I have a raidz pool running on Opensolaris b85. I wanted to try out freenas 0.7 and tried to add my pool to freenas. After adding the zfs disk, vdev and pool. I decided to back out and went back to opensolaris. Now my raidz pool will not mount and got the following errors. Hope someone expert can help me recover from this error.

This day went from usual Thursday to worst day of my life in the span of about 10 seconds. Here''s the scenario: 2 Computer, both Solaris 10u8, one is the primary, one is the backup. Primary system is RAIDZ2, Backup is RAIDZ with 4 drives. Every night, Primary mirrors to Backup using the ''zfs send'' command. The Backup receives that with ''zfs recv

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 > >

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

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

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, 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

Hi All, I''ve just built an 8 disk zfs storage box, and I''m in the testing phase before I put it into production. I''ve run into some unusual results, and I was hoping the community could offer some suggestions. I''ve bascially made the switch to Solaris on the promises of ZFS alone (yes I''m that excited about it!), so naturally I''m looking

Is it possible to build a raidz with different disk sizes? If so, are you limited to the size of the smallest disk (*ndisks)? -frank This message posted from opensolaris.org

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
