similar to: zpool status (advanced listing)?

I''m using Solaris 10u6 updated to u7 via patches, and I have a pool with a mirrored pair and a (shared) hot spare. We reconfigured disks a while ago and now the controller is c4 instead of c2. The hot spare was originally on c2, and apparently on rebooting it didn''t get found. So, I looked up what the new name for the hot spare was, then added it to the pool with "zpool

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.

I''m trying to write a SLAMD (http://www.slamd.com/) resource monitor that can be used to measure the I/O throughput on a ZFS pool, and in particular to be able to get the read and write rates. In order to do this, I''m basically executing "zpool iostat {interval}" and parsing the output to capture the values in the "bandwidth read" and "bandwidth

Hi All, I believe this has been asked before, but I wasn?t able to find too much information about the subject. Long story short, I was moving data around on a storage zpool of mine and a zfs destroy <filesystem> hung (or so I thought). This pool had dedup turned on at times while imported as well; it?s running on a Nexenta Core 3.0.1 box (snv_134f). The first time the machine was

Well, I''ve searched my brains out and I can''t seem to find a reason for this. I''m getting bad to medium performance with my new test storage device. I''ve got 24 1.5T disks with 2 SSDs configured as a zil log device. I''m using the Areca raid controller, the driver being arcmsr. Quad core AMD with 16 gig of RAM OpenSolaris upgraded to snv_134. The zpool

Hello ZFSland, Is there any significance in the fact that the bandwidth/read figures for a simple cpio into a ZFS filesystem should be multiples of 21.3K (when non-zero) as follows? What could determine this figure? Do I need to read a manpage? ;-) Thanks... Sean. ----- [root at global:/36g2] # zpool iostat 3 capacity operations bandwidth pool used avail read

What is the best way to tell if your bound by the number of individual operations per second / random io? "zpool iostat" has an "operations" column but this doesn''t really tell me if my disks are saturated. Traditional "iostat" doesn''t seem to be the greatest place to look when utilizing zfs.

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

Running a zpool scrub on our production pool is showing a scrub rate of about 400K/s. (When this pool was first set up we saw rates in the MB/s range during a scrub). Both zpool iostat and an iostat -Xn show lots of idle disk times, no above average service times, no abnormally high busy percentages. Load on the box is .59. 8 x 3GHz, 32GB ram, 96 spindles arranged into raidz zdevs on OI 147.

Evening all, I''m new to Solaris but after drooling over zfs for ages I finally took the plunge. First off I had 2x1Tb hdd in raid1 XFS format using mdadm, so using a opensolaris vm image I transfered one side of the mirror to the other in zfs. (using rsync and it took 3days!) So with a 1 disk zpool carrying all my data I brought both the drives over in a new box, all going swimmingly

Hello, Is it possible to non-destructively change RAID types in zpool while the data remains on-line? -J

So, my Areca controller has been complaining via email of read errors for a couple days on SATA channel 8. The disk finally gave up last night at 17:40. I got to say I really appreciate the Areca controller taking such good care of me. For some reason, I wasn''t able to log into the server last night or in the morning, probably because my home dir was on the zpool with the failed disk

Hi all, I have exchanged my Dell R610 in favor of a Sun Fire 4170 M2 which has 32 GB RAM installed. I am running Sol11Expr on this host and I use it to primarily serve Netatalk AFP shares. From day one, I have noticed that the amount of free RAM decereased and along with that decrease the overall performance of ZFS decreased as well. Now, since I am still quite a Solaris newbie, I seem to

I know this topic has been discussed many times... but what the hell makes zpool resilvering so slow? I''m running OpenSolaris 2009.06. I have had a large number of problematic disks due to a bad production batch, leading me to resilver quite a few times, progressively replacing each disk as it dies (and now preemptively removing disks.) My complaint is that resilvering ends up

Hi all, I''ve got a solaris 10 running 9/10 on a T3. It''s an oracle box with 128GB memory RIght now oracle . I''ve been trying to load test the box with bonnie++. I can seem to get 80 to 90 K writes, but can''t seem to get more than a couple K for writes. Any suggestions? Or should I take this to a bonnie++ mailing list? Any help is appreciated. I''m kinda

I have a raidz2 pool with one disk that seems to be going bad, several errors are noted in iostat. I have an RMA for the drive, however - no I am wondering how I proceed. I need to send the drive in and then they will send me one back. If I had the drive on hand, I could do a zpool replace. Do I do a zpool offline? zpool detach? Once I get the drive back and put it in the same drive bay..

I just installed build 41 of Nevada on a SunBlade 1500 with 2GB of ram. I wanted to check out zfs since the delay of S10U2 I really could not wait any longer :) I installed it on my system and created a zpool out of an approximately 40GB disk slice. I then wanted to build a version of thunderbird that contains a local patch that we like. So I download the source tar ball. I try to untar it on the

Hi gurus, I like zpool iostat and I like system monitoring, so I setup a script within sma to let me get the zpool iostat figures through snmp. The problem is that as zpool iostat is only run once for each snmp query, it always reports a static set of figures, like so: root at exodus:snmp # zpool iostat -v capacity operations bandwidth pool used avail read

I have a desktop system with 2 ZFS mirrors. One drive in one mirror is starting to produce read errors and slowing things down dramatically. I detached it and the system is running fine. I can''t tell which drive it is though! The error message and format command let me know which pair the bad drive is in, but I don''t know how to get any more info than that like the serial number
