similar to: Moving a pool from FreeBSD 8.0 to opensolaris

I''m playing around with ZFS and want to figure out the best use of my 6x 300GB SATA drives. The purpose of the drives is to store all of my data at home (video, photos, music, etc). I''m debating between: 6x 300GB disks in a single raidz2 pool --or-- 2x (3x 300GB disks in a pool) mirrored I''ve read up a lot on ZFS, but I can''t really figure out which is

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

I''ve been using a 5-disk raidZ for years on SXCE machine which I converted to OSOL. The only time I ever had zfs problems in SXCE was with snv_120, which was fixed. So, now I''m at OSOL snv_111b and I''m finding that scrub repairs errors on random disks. If I repeat the scrub, it will fix errors on other disks. Occasionally it runs cleanly. That it doesn''t

Hi, yesterday evening I tried to upgrade my Ultra 60 to 2009.06 from SXCE snv_98. I can''t use AI Installer because OpenPROM is version 3.27. So I built IPS from source, then created a zpool on a spare drive and installed OS 2006.06 on it To make the disk bootable I used: installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c0t1d0s0 using the executable from my new

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.

Hi Folks, I''m in the very unsettling position of fearing that I''ve lost all of my data via a zfs send/receive operation, despite ZFS''s legendary integrity. The error that I''m getting on restore is: receiving full stream of faith/home at 09-08-08 into Z/faith/home at 09-08-08 cannot receive: invalid stream (checksum mismatch) Background: I was running snv_91,

We recently installed a 24 disk SATA array with an LSI controller attached to a box running Solaris X86 10 Release 4. The drives were set up in one big pool with raidz, and it worked great for about a month. On the 4th, we had the system kernel panic and crash, and it''s now behaving very badly. Here''s what diagnostic data I''ve been able to collect so far: In the

Hello, I''m quite interested in ZFS, like everybody else I suppose, and am about to install FBSD with ZFS. On that note, i have a different first question to start with. I personally am a Linux fanboy, and would love to see/use ZFS on linux. I assume that I can use those ZFS disks later with any os that can work/recognizes ZFS correct? e.g. I can install/setup ZFS in FBSD, and later use

Hello list, I posted this a few days ago on opensolaris-discuss@ list I am posting here, because there my be too much noise on other lists I have been without this zfs set for a week now. My main concern at this point,is it even possible to recover this zpool. How does the metadata work? what tool could is use to rebuild the corrupted parts or even find out what parts are corrupted. most but

Hi All, I am looking at ZFS and I get that they call it RAIDZ which is similar to RAID 5, but what about RAID 10? Isn''t a RAID 10 setup better for data protection? So if I have 8 x 1.5tb drives, wouldn''t I: - mirror drive 1 and 5 - mirror drive 2 and 6 - mirror drive 3 and 7 - mirror drive 4 and 8 Then stripe 1,2,3,4 Then stripe 5,6,7,8 How does one do this with ZFS?

Given a 1.6TB ZFS Z-Raid consisting 6 disks: And a system that does an extreme amount of small /(<20K) /random reads /(more than twice as many reads as writes) / 1) What performance gains, if any does Z-Raid offer over other RAID or Large filesystem configurations? 2) What is any hindrance is Z-Raid to this configuration, given the complete randomness and size of these accesses? Would

Hello, I have a Dell 2950 with a Perc 5/i, two 300GB 15K SAS drives in a RAID0 array. I am considering going to ZFS and I would like to get some feedback about which situation would yield the highest performance: using the Perc 5/i to provide a hardware RAID0 that is presented as a single volume to OpenSolaris, or using the drives separately and creating the RAID0 with OpenSolaris and ZFS? Or

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

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

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

I have two identical Supermicro boxes with 32GB ram. Hardware details at the end of the message. They were running OI 151.a.5 for months. The zpool configuration was one storage zpool with 3 vdevs of 8 disks in RAIDZ2. The OI installation is absolutely clean. Just next-next-next until done. All I do is configure the network after install. I don''t install or enable any other services.

Setup: Osol.11 build 109 Athlon64 3400+ Aopen AK-86L mobo adeptec 1250sa Sata PCI controller card [re-posted from accidental post to osol `general'' group] I''m having trouble with an adaptec 1205sa (non-raid) SATA PCI card. It was all working fine when I plugged 2 used sata 200gb disks of a windows xp machine into it. Booted my osol server and added a zpool mirror using those

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
