Hi All, I''d like to ask about whether there is a method to enforce a certain txg commit frequency on ZFS. I''m doing a large amount of video streaming from a storage pool while also slowly continuously writing a constant volume of data to it (using a normal file descriptor, *not* in O_SYNC). When reading volume goes over a certain threshold (and average pool load over ~50%), ZFS

I''m trying to configure a DELL R720 (not a pleasant experience) which has an H710p card fitted. The H710p definitely doesn''t support JBOD, but the H310 looks like it might (the data sheet mentions non-RAID). Has anyone used one with ZFS? Thanks, -- Ian.

Hello Sa?o! I found you here: http://mail.opensolaris.org/pipermail/zfs-discuss/2012-May/051546.html "How about reflashing LSI firmware to the card? I read on Dell''s spec sheets that the card runs an LSISAS2008 chip, so chances are that standard LSI firmware will work on it. I can send you all the required bits to do the reflash, if you like." I got Dell Perc H310 controller

Hello, Has anyone out there been able to qualify the Proliant DL360 G7 for your Solaris/OI/Nexenta environments? Any pros/cons/gotchas (vs. previous generation HP servers) would be greatly appreciated. Thanks in advance! -Anh

While I understand everything at Oracle is "top secret" these days. Does anyone have any insight into a next-gen X4500 / X4540? Does some other Oracle / Sun partner make a comparable system that is fully supported by Oracle / Sun? http://www.oracle.com/us/products/servers-storage/servers/previous-products/index.html What do X4500 / X4540 owners use if they''d like more

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

Hi all, I''m not sure if the problem is with FreeBSD or ZFS or both so I cross-post (I known it''s bad). Well I''ve server running FreeBSD 9.0 with (don''t count / on differents disks) zfs pool with 36 disk. The performance is very very good on the server. I''ve one NFS client running FreeBSD 8.3 and the performance over NFS is very good : For example

Hi, I''ve ordered a new server with: - 4x600GB Toshiba 10K SAS2 Disks - 2x100GB OCZ DENEVA 2R SYNC eMLC SATA (no expander so I hope no SAS/ SATA problems). Specs: http://www.oczenterprise.com/ssd-products/deneva-2-r-sata-6g-2.5-emlc.html I want to use the 2 OCZ SSDs as mirrored intent log devices, but as the intent log needs quite a small amount of the disks (10GB?), I was wondering

HI, T5220, S10U4 + patches mdb -k > ::memstat While above is working (takes some time, ideally ::memstat -n 4 to use 4 threads could be useful) mpstat 1 shows: CPU minf mjf xcal intr ithr csw icsw migr smtx srw syscl usr sys wt idl 48 0 0 1922112 9 0 0 8 0 0 0 15254 6 94 0 0 So about 2mln xcalls per second. Let''s check with dtrace:

Hello, There is a feature of zfs (autoexpand, or zpool online -e ) that it can consume the increased LUN immediately and increase the zpool size. That would be a very useful ( vital ) feature in enterprise environment. Though when I tried to use it, it did not work. LUN expanded and visible in format, but zpool did not increase. I found a bug SUNBUG:6430818 (Solaris Does Not Automatically

Hi InstallShield(setup.exe) seems to be hang up just after extracting files with fresh maked & installed wine 0.9.5 from source on fedora core 4. Could you tell me work around or hint ? I have to put the ole32.dll from MS WinXP original into drive_c/windows/system32 ? InstallShield output are as follows. I think Setup.exe extract files(OK) and folk co-process(iKernel.exe;OK), then try to

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

Hi all. One of our server had a panic and now can''t mount the zpool anymore! Here is what I get at boot: Mar 21 11:09:17 SERVER142 ^Mpanic[cpu1]/thread=ffffffff90878200: Mar 21 11:09:17 SERVER142 genunix: [ID 603766 kern.notice] assertion failed: ss->ss_start <= start (0x670000b800 <= 0x67 00009000), file: ../../common/fs/zfs/space_map.c, line: 126 Mar 21 11:09:17 SERVER142

Hi. Just migrated to zfs on opensolaris. I copied data to the server using rsync and got this message: Oct 10 17:24:04 zetta ^Mpanic[cpu1]/thread=ffffff0007f1bc80: Oct 10 17:24:04 zetta genunix: [ID 683410 kern.notice] BAD TRAP: type=e (#pf Page fault) rp=ffffff0007f1b640 addr=fffffffecd873000 Oct 10 17:24:04 zetta unix: [ID 100000 kern.notice] Oct 10 17:24:04 zetta unix: [ID 839527 kern.notice]

<copied from opensolaris-dicuss as this probably belongs here.> I kept on trying to migrate my pool with children (see previous threads) and had the (bad) idea to try the -d option on the receive part. The system reboots immediately. Here is the log in /var/adm/messages Feb 8 16:07:09 amber unix: [ID 836849 kern.notice] Feb 8 16:07:09 amber ^Mpanic[cpu1]/thread=ffffff014ba86e40: Feb 8

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

Hi, System: Netra 1405, 4x450Mhz, 4GB RAM and 2x146GB (root pool) and 2x146GB (space pool). snv_98.

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

Recently, I''m benchmarking all kinds of stuff on my systems. And one question I can''t intelligently answer is what blocksize I should use in these tests. I assume there is something which monitors present disk activity, that I could run on my production servers, to give me some statistics of the block sizes that the users are actually performing on the production server.
