Hi Everyone ; I will soon be making a presentation comparing ZFS against Veritas Storage Foundation , do we have any document comparing features ? regards <http://www.sun.com/> http://www.sun.com/emrkt/sigs/6g_top.gif Mertol Ozyoney Storage Practice - Sales Manager Sun Microsystems, TR Istanbul TR Phone +902123352200 Mobile +905339310752 Fax +902123352222 Email

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.

apparently if you don''t order a J4200 with drives, you just get filler sleds that won''t accept a hard drive. (had to look at a parts breakdown on sunsolve to figure this out -- the docs should simply make this clear.) it looks like the sled that will accept a drive is part #570-1182. anyone know how i could order 12 of these?

While thinking about ZFS as the next generation filesystem without limits I am wondering if the real world is ready for this kind of incredible technology ... I''m actually speaking of hardware :) ZFS can handle a lot of devices. Once in the import bug (http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6761786) is fixed it should be able to handle a lot of disks. I want to

How can I set up a ZVOL that''s accessible by non-root users, too? The intent is to use sparse ZVOLs as raw disks in virtualization (reducing overhead compared to file-based virtual volumes). Thanks, -mg This message posted from opensolaris.org

Hi Ged; At the moment ZFS is not a shared file system nor a paralell file system. However lustre integration which will take some time will provide parallel file system abilities. I am unsure if lustre at the moment supports redundancy between storage nodes (it was on the road map) But ZFS at the moment supports Sun cluster 3.2 (no paralel acccess is supported) and new upcoming SAS Jbods

I''ve upgraded my system from ufs to zfs (root pool). By default, it creates a zvol for dump and swap. It''s a 4GB Ultra-45 and every late night/morning I run a job which takes around 2GB of memory. With a zvol swap, the system becomes unusable and the Sun Ray client often goes into "26B". So I removed the zvol swap and now I have a standard swap partition. The

Team, **Please respond to me and my coworker listed in the Cc, since neither one of us are on this alias** QUICK PROBLEM DESCRIPTION: Cu created a dataset which contains all the zvols for a particular zone. The zone is then given access to all the zvols in the dataset using a match statement in the zoneconfig (see long problem description for details). After the initial boot of the zone

Hi All ; What is the status of ZFS on linux and what are the kernel''s supported?

Hi all, Recently there''s been discussion [1] in the Linux community about how filesystems should deal with rename(2), particularly in the case of a crash. ext4 was found to truncate files after a crash, that had been written with open("foo.tmp"), write(), close() and then rename("foo.tmp", "foo"). This is because ext4 uses delayed allocation and may not

I had some trouble installing a zone on ZFS with S10u4 (bug in the postgres packages) that went away when I used a ZVOL-backed UFS filesystem for the zonepath. I thought I''d push on with the experiment (in the hope Live Upgrade would be able to upgrade such a zone). It''s a bit unwieldy, but everything worked reasonably well - performance isn''t much worse than straight

Experts, I''m installing Oracle 9i on Solaris 10 11/06(update 3),I created some zfs volumes which will be used by oracle data file,as: # zfs create -V 200m ora_pool/controlfile01_200m # zfs create -V 800m ora_pool/system_800m ... # ls -l /dev/zvol/rdsk/ora_pool lrwxrwxrwx 1 root root 39 Apr 11 12:23 controlfile01_200m -> ../../../../devices/pseudo/zfs at 0:1c,raw

Hi. I'm moving some of my geli installation to a new machine. On an old machine it was running UFS. I use ZFS on a new machine, but I don't have an encrypted main pool (and I don't want to), so I'm kinda considering a way where I will make a zpool on a zvol encrypted by geli. Would it be completely insane (should I use UFS instead ?) or would it be still valid ? Thanks. Eugene.

Hi all! First off, if this has been discussed, please point me in that direction. I have searched high and low and really can''t find much info on the subject. We have a large-ish (200gb) UFS file system on a Sun Enterprise 250 that is being shared with samba (lots of files, mostly random IO). OS is Solaris 10u3. Disk set is 7x36gb 10k scsi, 4 internal 3 external. For several

The `lofiadm'' man page describes how to export a file as a block device and then use `mkfs -F pcfs'' to create a FAT filesystem on it. Can''t I do the same thing by first creating a zvol and then creating a FAT filesystem on it? Nothing I''ve tried seems to work. Isn''t the zvol just another block device? -- -Gary Mills- -Unix Group-

Hi There, I looked at the ZFS admin guide in attempt to find a way to leverage ZFS capabilities (storage pool, mirroring, dynamic stripping, etc.) for Xen domU file systems that are not ZFS. Couldn''t find an answer whether ZFS could be used only as a "regular" volume manager to create logical volumes for UFS or even a Linux ext2fs, with ideally, the ability to create

It wouldn''t be proper to start my first post here without congratulations and thanks to the ZFS team for such an impressive piece of work. Anyway, on to my query. I''ve been trying out ZFS, with a particular focus in reducing latency in a specific application. This application has a fair amount of random writing going on in the background (which, of course, ZFS will make

Hello list, someone (actually neil perrin (CC)) mentioned in this thread: http://mail.opensolaris.org/pipermail/zfs-discuss/2009-December/034340.html that is should be possible to import a pool with failed log devices (with or without data loss ?). >/ />/ Has the following error no consequences? />/ />/ Bug ID 6538021 />/ Synopsis Need a way to force pool startup when

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 zpool and zfs report different free space because zfs takes into account an internal reservation of 32MB or 1/64 of the capacity of the pool, what is bigger. So in a 2TB Harddisk, the reservation would be 32 gigabytes. Seems a bit excessive to me... - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ jcea at jcea.es -

Hi All, I''d like to set up dumping to a file. This file is on a mirrored pool using zfs. It seems that the dump setup doesn''t work with zfs. This worked for both a standard UFS slice and a SVM mirror using zfs. Is there something that I''m doing wrong, or is this not yet supported on ZFS? Note this is Solaris 10 Update 3, but I don''t think that should
