Mixing RAID levels in a pool
Hi, I had a plan to set up a zfs pool with different raid levels but I ran into an issue based on some testing I''ve done in a VM. I have 3x 750 GB hard drives and 2x 320 GB hard drives available, and I want to set up a RAIDZ for the 750 GB and mirror for the 320 GB and add it all to the same pool. I tested detaching a drive and it seems to seriously mess up the entire pool and I

zpool status my_pool , shows a pulled disk c1t6d0 as ONLINE ???
New server build with Solaris-10 u5/08, on a SunFire t5220, and this is our first rollout of ZFS and Zpools. Have 8 disks, boot disk is hardware mirrored (c1t0d0 + c1t1d0) Created Zpool my_pool as RaidZ using 5 disks + 1 spare: c1t2d0, c1t3d0, c1t4d0, c1t5d0, c1t6d0, and spare c1t7d0 I am working on alerting & recovery plans for disks failures in the zpool. As a test, I have pulled disk

Help understanding some benchmark results
G''day, all, So, I''ve decided to migrate my home server from Linux+swRAID+LVM to Solaris+ZFS, because it seems to hold much better promise for data integrity, which is my primary concern. However, naturally, I decided to do some benchmarks in the process, and I don''t understand why the results are what they are. I though I had a reasonable understanding of ZFS, but now

zfs raidz questions
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

Recovering a broken mirror
We have a production SunFireV240 that had a zfs mirror until this week. One of the drives (c1t3d0) in the mirror failed. The system was shutdown and the bad disk replaced without an export. I don''t know what happened next but by the time I got involved there was no evidence that the remaining good disk (c1t2d0) had ever been part of a ZFS mirror. Using dd on the raw device I can see data

Mixing RAIDZ and RAIDZ2 zvols in the same zpool
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 > >

determining raidz pool configuration
Hi all, Sorry for the newbie question, but I''ve looked at the docs and haven''t been able to find an answer for this. I''m working with a system where the pool has already been configured and want to determine what the configuration is. I had thought that''d be with zpool status -v <poolname>, but it doesn''t seem to agree with the

understanding zfs/thunoer "bottlenecks"?
Currently I''m trying to figure out the best zfs layout for a thumper wrt. to read AND write performance. I did some simple mkfile 512G tests and found out, that per average ~ 500 MB/s seems to be the maximum on can reach (tried initial default setup, all 46 HDDs as R0, etc.). According to http://www.amd.com/us-en/assets/content_type/DownloadableAssets/ArchitectureWP_062806.pdf I would

The pool will continue to function, possibly in a degraded state. action: Wait for the resilver to complete. scrub:

How to replace root drive if ZFS data is on it?
Hi, Experts: A customer has X4500 and the boot drives mirrored (c5t0d0s0 and c5t4d0s0) by SVM, The ZFS uses the two other partitions on these two drives(c5t0d0s3 and c5t4d0s3). If we need to replace the disk drive c5t0d0, do we need to do anything on the ZFS (c5t0d0s3 and c5t4d0s3) first or just follow the regular boot drive replacement procedure? Below is the summary of their current ZFS

ZFS mirror to RAIDz?
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.

Can this be done?
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

zpool mirror (dumb question)
Hi there! I am new to the list, and to OpenSolaris, as well as ZPS. I am creating a zpool/zfs to use on my NAS server, and basically I want some redundancy for my files/media. What I am looking to do, is get a bunch of 2TB drives, and mount them mirrored, and in a zpool so that I don''t have to worry about running out of room. (I know, pretty typical I guess). My problem is, is that

Sol 10 x86_64 intermittent SATA device locks up server
Hello All, I have an issue where I have two SATA cards with 5 drives each in one zfs pool. The issue is one of the devices has been intermittently failing. The problem is that the entire box seems to lock up on occasion when this happens. I currently have the SATA cable to that device disconnected in the hopes that the box will at least stay up for now. This is a new build that I am

[storage-discuss] high read iops - more memory for arc?
Pre-fletching on the file and device level has been disabled yielding good results so far. We''ve lowered the number of concurrent ios from 35 to 1 causing the service times to go even lower (1 -> 8ms) but inflating actv (.4 -> 2ms). I''ve followed your recommendation in setting primarycache to metadata. I''ll have to check with our tester in the morning if it made

high read iops - more memory for arc?
I''m running into a issue where there seems to be a high number of read iops hitting disks and physical free memory is fluctuating between 200MB -> 450MB out of 16GB total. We have the l2arc configured on a 32GB Intel X25-E ssd and slog on another32GB X25-E ssd. According to our tester, Oracle writes are extremely slow (high latency).

Help! ZFS pool is UNAVAILABLE
Hi All, I posted this in a different threat, but it was recommended that I post in this one. Basically, I have a 3 drive raidz array on internal Seagate drives. running build 64nv. I purchased 3 add''l USB drives with the intention of mirroring and then migrating the data to the new USB drives. I accidentally added the 3 USB drives in a raidz to my original storage pool, so now I have 2
