similar to: RAID-Z/mirror hybrid allocator

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, I am using FreeBSD 8.2 and went to add 4 new disks today to expand my offsite storage. All was working fine for about 20min and then the new drive cage started to fail. Silly me for assuming new hardware would be fine :( The new drive cage started to fail, it hung the server and the box rebooted. After it rebooted, the entire pool is gone and in the state below. I had only written a few

In 2007 I bought 6 WD1600JS 160GB sata disks and used 4 to create a raidz storage pool and then shelved the other two for spares. One of the disks failed last night so I shut down the server and replaced it with a spare. When I tried to zpool replace the disk I get: zpool replace tank c10t0d0 cannot replace c10t0d0 with c10t0d0: device is too small The 4 original disk partition tables look like

On Solaris 10 If I install using ZFS root on only one drive is there a way to add another drive as a mirror later? Sorry if this was discussed already. I searched the archives and couldn''t find the answer. Thank you.

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

I have one drive that I''m running OpenSolaris on and a 6-drive RAIDZ. Unfortunately I don''t have another drive to mirror the OS drive, so I was wondering what the best way to back up that drive is. Can I mirror it onto a file on the RAIDZ, or will this cause problems before the array is loaded when booting? What about zfs send and recv to the RAIDZ? -- This message posted from

Hi, for zfs raidz1, I know for random io, iops of a raidz1 vdev eqaul to one physical disk iops, since raidz1 is like raid5 , so is raid5 has same performance like raidz1? ie. random iops equal to one physical disk''s ipos. Regards Victor -- This message posted from opensolaris.org

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 zpool and zfs report different free space because zfs takes into account an internal reservation of 32MB or 1/64 of the capacity of the pool, what is bigger. So in a 2TB Harddisk, the reservation would be 32 gigabytes. Seems a bit excessive to me... - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ jcea at jcea.es -

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

I''m trying to get maybe 200 MB/sec over NFS for large movie files (need large capacity to hold all of them). Are there any rules of thumb on how much RAM is needed to handle this (probably RAIDZ for all the disks) with zfs, and how large a server should be used? The throughput required is not so large, so I am thinking an X4100 M2 or X4150 should be plenty. This message posted from

Hi, I hope there''s someone here who can possibly provide some assistance. I''ve had this read problem now for the past 2 months and just can''t get to the bottom of it. I have a home snv_111b server, with a zfs raid pool (4 x Samsung 750GB SATA drives). The motherboard is a ASUS M2N68-CM (4 SATA ports) with an Athlon LE1620 single core CPU and 4GB of RAM. I am using it

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 seen conflicting examples on how to create zpools using full disks. The zpool(1M) page uses "c0t0d0" but OpenSolaris Bible and others show "c0t0d0p0". E.g.: zpool create tank raidz c0t0d0 c0t1d0 c0t2d0 c0t3d0 c0t4d0 c0t5d0 zpool create tank raidz c0t0d0p0 c0t1d0p0 c0t2d0p0 c0t3d0p0 c0t4d0p0 c0t5d0p0 I have not been able to find any discussion on whether (or when) to

<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

I?ve spend a few hours reading through the forums and wiki and honestly my head is spinning. I have been trying to study up on either buying or building a box that would allow me to add drives of varying sizes/speeds/brands (adding more later etc) and still be able to use the full space of drives (minus parity? [not sure if I got the terminology right]) with redundancy. I have found the ?all in

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

Ok, previous threads have lead me to believe that I want to make raidz vdevs [0] either 3, 5 or 9 disks in size [1]. Let''s say I have 8 disks. Do I want to create a zfs pool with a 5-disk vdev and a 3-disk vdev? Are there performance issues with mixing differently sized raidz vdevs in a pool? If there *is* a performance hit to mix like that, would it be greater or lesser than building

Hello list, I''m having trouble with a server holding a lot of data. After a few months of uptime, it is currently rebooting from a lockup (reason unknown so far) but it is taking hours to boot up again. The boot process is stuck at the stage where it says: mounting zfs filesystems (1/5) the machine responds to pings and keystrokes. I can see disk activity; the disk leds blink one after
