Deterioration with zfs performace and recent zfs bits?
Has anyone else noticed a significant zfs performance deterioration
when running recent opensolaris bits?
My 32-bit / 768 MB Toshiba Tecra S1 notebook was able to do a
full opensolaris release build in ~ 4 hours 45 minutes (gcc shadow
compilation disabled; using an lzjb compressed zpool / zfs on a
single notebook hdd p-ata drive).

Extremely poor ZFS perf and other observations
I''m observing the following behavior in our environment (Sol10U2, E2900, 24x96, 2x2Gbps, ...)
- I''ve a compressed ZFS filesystem where I''m creating a large tar file. I notice that the tar process is running fine (accumulating CPU, truss shows writes, ...) but for whatever reason the timestamp on the file doesn''t change nor does the file size change. The same is

Possible ZFS Bug - Causes OpenSolaris Crash
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

ZFS panic when trying to import pool
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

lots of small, twisty files that all look the same
A customer has a zpool where their spectral analysis applications create a ton (millions?) of very small files that are typically 1858 bytes in length. They''re using ZFS because UFS consistently runs out of inodes. I''m assuming that ZFS aggregates these little files into recordsize (128K?) blobs for writes. This seems to go reasonably well amazingly enough. Reads are a

Currently I''m trying to figure out the best zfs layout for a thumper wrt. to read AND write performance.

2. there is other why to get the same configuration?

ZFS, SATA, LSI and stability
After having massive problems with a supermicro X7DBE box using AOC-SAT2-MV8 Marvell controllers and opensolaris snv79 (same as described here: http://sunsolve.sun.com/search/document.do?assetkey=1-66-233341-1) we just start over using new hardware and opensolaris 2008.05 upgraded to snv94. We used again a supermicro X7DBE but now with two LSI SAS3081E SAS controllers. And guess what? Now we get

Samba with ZFS ACL
Hi,
I''m looking for Samba, which work native ZFS ACL.
With ZFS almost everything work except native ZFS ACL.
I have learned on samba mailing list, that it dosn''t work while samba-3.2.0 will be released.
Has anyone knows any solution to work samba-3.0.25?
If any idea, please let me know.

There are new binaries planned. They are built even. Just being held

Efficiency when reading the same file blocks
if you have N processes reading the same file sequentially (where file size is much greater than physical memory) from the same starting position, should I expect that all N processes finish in the same time as if it were a single process?
In other words, if you have one process that reads blocks from a file, is it "free" (meaning no additional total I/O cost) to have another process

Live Upgrade Solaris 10 UFS to ZFS boot pre-requisites?
I have a Solaris 10 U5 system massively patched so that it supports
ZFS pool version 15 (similar to U8, kernel Generic_141445-09), live
upgrade components have been updated to Solaris 10 U8 versions from
the DVD, and GRUB has been updated to support redundant menus across
the UFS boot environments.
I have studied the Solaris 10 Live Upgrade manual (821-0438) and am

gzip compression throttles system?
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?
