Hi. T2000 1.2GHz 8-core, 32GB RAM, S10U3, zil_disable=1. Command ''zpool export f3-2'' is hung for 30 minutes now and still is going. Nothing else is running on the server. I can see one CPU being 100% in SYS like: bash-3.00# mpstat 1 [...] CPU minf mjf xcal intr ithr csw icsw migr smtx srw syscl usr sys wt idl 0 0 0 67 220 110 20 0 0 0 0

Hello ZFS, System was rebooted and after reboot server again System is snv_39, SPARC, T2000 bash-3.00# ptree 7 /lib/svc/bin/svc.startd -s 163 /sbin/sh /lib/svc/method/fs-local 254 /usr/sbin/zfs mount -a [...] bash-3.00# zfs list|wc -l 46 Using df I can see most file systems are already mounted. > ::ps!grep zfs R 254 163 7 7 0 0x4a004000

We are using MySQL, and love the idea of using zfs for this. We are used to using Direct I/O to bypass file system caching (let the DB do this). Does this exist for zfs? This message posted from opensolaris.org

One of our Solaris 10 update 3 servers paniced today with the following error: Sep 18 00:34:53 m2000ef savecore: [ID 570001 auth.error] reboot after panic: assertion failed: ss != NULL, file: ../../common/fs/zfs/space_map.c, line: 125 The server saved a core file, and the resulting backtrace is listed below: $ mdb unix.0 vmcore.0 > $c vpanic() 0xfffffffffb9b49f3() space_map_remove+0x239()

Hello, I have several ~12TB storage servers using Solaris with ZFS. Two of them have recently developed performance issues where the majority of time in an spa_sync() will be spent in the space_map_*() functions. During this time, "zpool iostat" will show 0 writes to disk, while it does hundreds or thousands of small (~3KB) reads each second, presumably reading space map data from

I have a huge problem with ZFS pool fragmentation. I started investigating problem about 2 weeks ago http://www.opensolaris.org/jive/thread.jspa?threadID=34423&tstart=0 I found workaround for now - changing recordsize - but I want better solution. The best solution would be a defragmentator tool, but I can see that it is not easy. When ZFS pool is fragmented then: 1. spa_sync function is

I''m trying to do some userspace tracing on a server-process with the pid provider. My problem is, that the only probes the pid-provider lists for the server-process (to which I attach dtrace with "-p nnnn") are coming from "ld.so.1". There''s not a single one from my modules. If I''m specifying "a.out" (or any of our shared-objects) as the

I have a raid-z zfs filesystem with 3 disks. The disk was starting have read and write errors. The disks was so bad that I started to have trans_err. The server lock up and the server was reset. Then now when trying to import the pool the system panic. I installed the last Recommend on my Solaris U3 and also install the last Kernel patch (120011-14). But still when trying to do zpool import

When unpacking the solaris source onto a local disk on a system running build 39 I got the following panic: panic[cpu0]/thread=d2c8ade0: really out of space d2c8a7b4 zfs:zio_write_allocate_gang_members+3e6 (e4385ac0) d2c8a7d0 zfs:zio_dva_allocate+81 (e4385ac0) d2c8a7e8 zfs:zio_next_stage+66 (e4385ac0) d2c8a800 zfs:zio_checksum_generate+5e (e4385ac0) d2c8a81c zfs:zio_next_stage+66 (e4385ac0)

Dear fellow CentOS users, I have never experienced this problem with hard disk management before and cannot explain it to myself on any rational basis. The setup: I have a workstation for testing, running latest CentOS 7.3 AMD64. I am evaluating oVirt and a storage-ha as part of my bachelors thesis. I have already been running a RAID1 (mdraid, lvm2) for the system and some oVirt 4.1 testing.

Hi Folks, I''ve got a 3.9 Tb zpool, and it is casing kernel panics on my Solaris 10 280r (SPARC) server. The message I get on panic is this: panic[cpu1]/thread=2a100a95cc0: zfs: freeing free segment (offset=423713792 size=1024) This seems to come about when the zpool is being used or being scrubbed - about twice a day at the moment. After the reboot, the scrub seems to have

I?d like to report the ZFS related crash/bug described below. How do I go about reporting the crash and what additional information is needed? I?m using my own very simple test app that creates numerous directories and files of randomly generated data. I have run the test app on two machines, both 64 bit. OpenSolaris crashes a few minutes after starting my test app. The crash has occurred on

I just had a quick play with gzip compression on a filesystem and the result was the machine grinding to a halt while copying some large (.wav) files to it from another filesystem in the same pool. The system became very unresponsive, taking several seconds to echo keystrokes. The box is a maxed out AMD QuadFX, so it should have plenty of grunt for this. Comments? Ian
