Hi, Well I have a freshly built system with ZFS raidz. Intel P4 2.4 Ghz 1GB Ram Marvell Technology Group Ltd. MV88SX6081 8-port SATA II PCI-X Controller (2) Intel Dual Port 1Gbit nics I have (5) 300GB disks in a Raidz1 with Zfs. I''ve created a couple of FS on this. /export/downloads /export/music /export/musicraw I''ve shared these out as well. First with ZFS ''zfs

Hi, I am measuring the performance of my newly bought NAS with IOZone. The NAS is of an embedded linux with samba installed. (CPU is Intel Atom) The IOZone reported that write performance to be over 1GBps while the file size less or equals to 1GB. Since the nic is 1Gbps, the maximum speed is supposed to be 125MiBps at most. The testing report of IOZone is amazing. Later I found that If the

Hello: Sorry for asking iozone ques in this mailing list but couldn't find any mailing list on iozone... In IOZone, is there a way to configure # of outstanding requests client sends to server side? Something on the lines of IOMeter option "Number of outstanding requests". Thanks a lot!

I'm testing iozone inside a VM booted from a gluster volume. By looking at network traffic on the host (the one connected to the gluster storage) I can see that a simple iozone -w -c -e -i 0 -+n -C -r 64k -s 1g -t 1 -F /tmp/gluster.ioz will make about 1200mbit/s on a bonded dual gigabit nic (probably, with a bad bonding mode configured) fio returns about 50000kB/s, that are 400000 kbps.

Dear ALL, IHAC who would like to use Sun Fire X4500 to be the NFS server for the backend services, and would like to see the potential performance gain comparing to their existing systems. However the outputs of the I/O stress test with iozone show the mixed results as follows: * The read performance sharply degrades (almost down to 1/20, i.e from 2,000,000 down to 100,000) when the

Having done a current checkout, creating a new FS and running iozone [1] on it results in an oops [2]. remove_suid is called, accessing offset 14 of a NULL pointer. Let me know if you''d like me to test any fix, do further debugging or get more information. Thanks, Daniel --- [1] # mkfs.btrfs /dev/sda4 # mount /dev/sda4 /mnt /mnt# iozone -a . --- [2] [ 899.118926] BUG: unable to

Hi folks, I would appreciate it if someone can help me understand some weird results I''m seeing with trying to do performance testing with an SSD offloaded ZIL. I''m attempting to improve my infrastructure''s burstable write capacity (ZFS based WebDav servers), and naturally I''m looking at implementing SSD based ZIL devices. I have a test machine with the

Hi all, Get your questions ready as tomorrow's VUC call will feature Shidan Gouran, CTO of Jazinga, makers of a new Asterisk appliance. Jazinga have developed a web 2.0 GUI for their embedded Asterisk appliance. We all love GUIs, right? They want to make it easy for a non-techie to setup a small office Asterisk solution. For details about the Jazinga product you can see Michael Graves'

Hi Matt, Can you please provide us with more information? 1. what version of glusterfs are you using 2. Was the iozone run as root or user? a. if user, did it have the required permissions? 3. steps to reproduce the problem 4. Any other errors related to stripe in the clinet log? With regards, Shishir ________________________________________ From: gluster-users-bounces at gluster.org

Here are my results: Summary: I am not able to reproduce the problem, IOW I get relatively equivalent numbers for sequential IO when going against 3.10.5 or 3.12.0 Next steps: - Could you pass along your volfile (both for a brick and also the client vol file (from /var/lib/glusterd/vols/<yourvolname>/patchy.tcp-fuse.vol and a brick vol file from the same place) - I want to check

I''m running Postgresql (v8.1.10) on Solaris 10 (Sparc) from within a non-global zone. I originally had the database "storage" in the non-global zone (e.g. /var/local/pgsql/data on a UFS filesystem) and was getting performance of "X" (e.g. from a TPC-like application: http://www.tpc.org). I then wanted to try relocating the database storage from the zone (UFS

Greetings Gentlemen, I''m currently testing a new setup for a ZFS based storage system with dedup enabled. The system is setup on OI 148, which seems quite stable w/ dedup enabled (compared to the OpenSolaris snv_136 build I used before). One issue I ran into, however, is quite baffling: With iozone set to 32 threads, ZFS''s ARC seems to consume all available memory, making

Hi, We''re doing some benchmarking at a customer (using IOzone) and for some specific small block random tests, performance of their X4500 is very poor (~1.2 MB/s aggregate throughput for a 5+1 RAIDZ). Specifically, the test is the IOzone multithreaded throughput test of an 8GB file size and 8KB record size, with the server physmem''d to 2GB. I noticed a couple of peculiar

Dear Jatin, Maybe it’s a good idea first to implement Spice: <video> <model type='qxl' ram='65536' vram='65536' heads='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video>

Hi, I am currently making some i/o performance tests within domUs with iozone3. One scenario is a domU with file-backed VBDs (root and swap) as sda1 and sda2 lying on an nfs-kernel-server (2.6.14.4 - Debian Sarge). The exact iozone command is: iozone -a -R -b result.xls -f /tmp/iozone.test -n 1m -g 256m -i 0 -i 1 As soon as the iozone-test comes to a filesize of 132M, the complete! system

Why don?t you set LSI to passtrough mode and set one brick per HDD?
