Today I updated the firmware on my StorageTek 2540 to the latest recommended version and am seeing radically difference performance when testing with iozone than I did in February of 2008. I am using Solaris 10 U5 with all the latest patches. This is the performance achieved (on a 32GB file) in February last year: KB reclen write rewrite read reread 33554432

I encountered an issue that people using OS-X systems as NFS clients need to be aware of. While not strictly a ZFS issue, it may be encounted most often by ZFS users since ZFS makes it easy to support and export per-user filesystems. The problem I encountered was when using ZFS to create exported per-user filesystems and the OS-X automounter to perform the necessary mount magic. OS-X

Under Solaris 10 on a 4 core Sun Ultra 40 with 20GB RAM, I am setting up a Sun StorageTek 2540 with 12 300GB 15K RPM SAS drives and connected via load-shared 4Gbit FC links. This week I have tried many different configurations, using firmware managed RAID, ZFS managed RAID, and with the controller cache enabled or disabled. My objective is to obtain the best single-file write performance.

ZFS experts! cu is looking for _documentation_ about putting zone paths on zfs. cu is running 5.10 KP 137111-06. he needs to make sure u5 kp is ok with zone roots. Also has FSs mounted via legacy. So...anybody have documentation on which u5 or u6 of Solaris (NOT OpenSolaris) supports zfs, if any update, for zone paths? -Brian -------- Original Message -------- Subject: RE: Sun#

Hi, I hope there''s someone here who can possibly provide some assistance. I''ve had this read problem now for the past 2 months and just can''t get to the bottom of it. I have a home snv_111b server, with a zfs raid pool (4 x Samsung 750GB SATA drives). The motherboard is a ASUS M2N68-CM (4 SATA ports) with an Athlon LE1620 single core CPU and 4GB of RAM. I am using it

We have a virtualized environment of T-Series where each host has either zones or LDoms. All of the virtual systems will have their own dedicated storage on ZFS (and some may also get raw LUNs). All the SAN storage is delivered in fixed sized 33GB LUNs. The question I have to the community is whether it would be better to have a pool per virtual system, or create a large pool and carve out ZFS

I''ve got a server that freezes when I run a zpool scrub from cron. Zpool scrub runs fine from the command line, no errors. The freeze happens within 30 seconds of the zpool scrub happening. The one core dump I succeeded in taking showed an arccache eating up all the ram. The server''s running Solaris 10 u3, kernel patch 127727-11 but it''s been patched and seems to have

Hi all, I''ve been trying to install GraphicsMagick with RMagic. I''ve tried ImageMagick with RMagic as well. I''ve tried the installations using Darwin Ports, Gems and from source. Nothing seems to work properly. My specs: ruby --version ruby 1.8.4 (2005-12-24) [powerpc-darwin8.5.0] rails --version Rails 1.1.0 convert -version Version: ImageMagick 6.1.8 04/05/06 Q16

I''m looking for a way to backup my entire system, the rpool zfs pool to an external HDD so that it can be recovered in full if the internal HDD fails. Previously with Solaris 10 using UFS I would use ufsdump and ufsrestore, which worked so well, I was very confident with it. Now ZFS doesn''t have an exact replacement of this so I need to find a best practice to replace it.

I am using RMagick to convert some files served up by a rails app from tiff''s to pdf''s on the fly. I have Imagemagick installed but was having trouble with some of the conversions. I tried installing GraphicsMagick and running the conversions manually and they work fine using GraphicsMagick. (They do not work properly even manually with ImageMagick.) I can''t see

I''m building another 24-bay rackmount storage server, and I''m considering what drives to put in the bays. My chassis is a Supermicro SC846A, so the backplane supports SAS or SATA; my controllers are LSI3081E, again supporting SAS or SATA. Looking at drives, Seagate offers an enterprise (Constellation) 2TB 7200RPM drive in both SAS and SATA configurations; the SAS model offers

If there were a ?zfs send? datastream saved someplace, is there a way to verify the integrity of that datastream without doing a ?zfs receive? and occupying all that disk space? I am aware that ?zfs send? is not a backup solution, due to vulnerability of even a single bit error, and lack of granularity, and other reasons. However ... There is an attraction to ?zfs send? as an augmentation to the

Hi all Is it possible to securely delete a file from a zfs dataset/zpool once it''s been snapshotted, meaning "delete (and perhaps overwrite) all copies of this file"?
