similar to: zpool status my_pool , shows a pulled disk c1t6d0 as ONLINE ???

Hello zfs-discuss, One of a disk started to behave strangely.

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

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

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

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). Below is a snippet of iostat: r/s w/s

Hi experts zpool import shows some weird config of an old zpool bash-3.00# zpool import pool: data1 id: 7539031628606861598 state: FAULTED status: One or more devices are missing from the system. action: The pool cannot be imported. Attach the missing devices and try again. see: http://www.sun.com/msg/ZFS-8000-3C config: data1 UNAVAIL insufficient replicas

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

Hi, Is it possible to convert a zfs pool from a concatenation of 2 disks to a 2 way mirror without backing up the data, re-creating the pool and restoring it. i.e diskA,diskB ----> mirror(diskA,diskB) Thanks, Jeff

I am curious why zpool status reports a pool to be in the DEGRADED state after a drive in a raidz2 vdev has been successfully replaced. In this particular case drive c0t6d0 was failing so I ran, zpool offline home/c0t6d0 zpool replace home c0t6d0 c8t1d0 and after the resilvering finished the pool reports a degraded state. Hopefully this is incorrect. At this point is the vdev in question now has

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 all, I''m building a file server (or just a storage that I intend to access by Workgroup from primarily Windows machines) using zfs raidz2 and openindiana 148. I will be using this to stream blu-ray movies and other media, so I will be happy if I get just 20MB/s reads, which seems like a pretty low standard considering some people are getting 100+. This is my first time with OI, and

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

I''ve got a Thumper running snv_57 and a large ZFS pool. I recently noticed a drive throwing some read errors, so I did the right thing and zfs replaced it with a spare. Everything went well, but the resilvering process seems to be taking an eternity: # zpool status pool: bigpool state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was

Hi, One of my colleagues was confused by the output of ''zpool status'' on a pool where a hot spare is being resilvered in after a drive failure: $ zpool status data pool: data state: DEGRADED status: One or more devices is currently being resilvered. The pool will continue to function, possibly in a degraded state. action: Wait for the resilver to complete. scrub:

Ok, this is not a OpenSolaris question, but it is a Solaris and ZFS question. I have a pool with three mirrored vdevs. I just got an error message from FMD that read failed from one on the disks,(c1t6d0). All with instructions on how to handle the problem and replace the devices, so far everything is good. But the zpool still thinks everything is fine. Shouldn''t zpool also show

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

how does one free segment(offset=77984887808 size=66560) on a pool that won''t import? looks like I found http://bugs.opensolaris.org/view_bug.do?bug_id=6580715 http://mail.opensolaris.org/pipermail/zfs-discuss/2007-September/042541.html when I luupgrade a ufs partition with a dvd-b62 that was bfu to b68 with a dvd of b74 it booted fine and I was doing the same thing that I had done on

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
