similar to: News on Single Drive RaidZ Expansion?

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

I am new to Ruby, and am trying out wxRuby, is there a place to find examples of code to make system tray icons with left and right click menus? Cross platform is ideal, but win32 specific if necc... thanks!

Apologies for the blank message (if it came through). I have heard here and there that there might be in development a plan to make it such that a raid-z can grow its "raid-z''ness" to accommodate a new disk added to it. Example: I have 4Disks in a raid-z[12] configuration. I am uncomfortably low on space, and would like to add a 5th disk. The idea is to pop in disk 5 and have

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 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 > >

Since ZFS already has error correction, would drives that limit the time a hard drive attempts to recover from errors such as WD RE drives or Seagate ES drive be necessary? Would it be safe to use standard hard drives without the Time Limited Error Recovery feature in a RAIDZ array? This message posted from opensolaris.org

I currently have a 7x1.5tb raidz1. I want to add "phase 2" which is another 7x1.5tb raidz1 Can I add the second phase to the first phase and basically have two raid5''s striped (in raid terms?) Yes, I probably should upgrade the zpool format too. Currently running snv_104. Also should upgrade to 110. If that is possible, would anyone happen to have the simple command lines to

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

<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

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 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 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

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

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

Hi, I have E450 with 20 SCSI disks. 1 disk is used as a boot disk with critical filesystems like /, /usr, /var, etc. then othe 19 disks are configured with ZFS in raidz. Are there any significant performance implications of using raidz with such a large number of disks? Would there much to be gained in performance if I were to simply configure striping across those disks, instead of raidz? This

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

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

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 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, 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
