Ext3 and 3ware RAID5
I run a decent amount of 3ware hardware, all under centos-4. There seems
to be some sort of fundamental disagreement between ext3 and 3ware's
hardware RAID5 mode that trashes write performance. As a representative
example, one current setup is 2 9550SX-12 boards in hardware RAID5 mode
(256KB stripe size) with a software RAID0 stripe on top (also 256KB
chunks). bonnie++ results look

Stress test zfs
Hi all,
I''ve got a solaris 10 running 9/10 on a T3. It''s an oracle box with 128GB
memory RIght now oracle . I''ve been trying to load test the box with
bonnie++. I can seem to get 80 to 90 K writes, but can''t seem to get more
than a couple K for writes. Any suggestions? Or should I take this to a
bonnie++ mailing list? Any help is appreciated. I''m kinda

Tyan Thunder K8SE S2892 Report
I had my eye on the Tyan dual-Opteron mobos for awhile. I tried to find
a posting *anywhere* sharing experiences with these boards under Linux.
No such luck. So placing myself under the heading "Where Angles Fear to
Tread," I went ahead and built a system anyway. Here's what I've learned.
The specs:

CentOS 3.1: sshd and pam /etc/security/limits.conf file descriptor settings problem
Why can't non-uid 0 users have more than 1024 file descriptors when
logging in via ssh?
I'm trying to allow a user to have a hard limit of 8192 file
descriptors(system defaults to 1024) via the following setting in
/etc/security/limits.conf:
jdoe hard nofile 8192
But when jdoe logs in via ssh and does 'ulimit -Hn' he gets '1024' as a
response. If he tries to

Physical disks + Software Raid + lvm in domU
Hi,
I''m trying to setup my box as described below:
- The Dom0 exports two disks as physical devices to the DomU
- DomU use the two devices to assemble a software raid device (/dev/md0)
- On the /dev/md0 I create a lvm volume group and lvm volumes on it.
Everything seems to work fine if the lvm volumes on the DomU are lightly
used. Under heavy load the DomU freeze up immediately.

Poor RAID performance new Xeon server?
I have just purchased an HP ProLiant HP ML110 G5 server and install ed
CentOS 5.2 x86_64 on it.
It has the following spec:
Intel(R) Xeon(R) CPU 3065 @ 2.33GHz
4GB ECC memory
4 x 250GB SATA hard disks running at 1.5GB/s
Onboard RAID controller is enabled but at the moment I have used mdadm
to configure the array.

server disk subsystem benchmarks, bonnie++ and/or others?
Greetings
I've searched to no avail so far... there is bound to be something more
intelligible out there...???
I am playing with bonnie++ for the first time...
May I please get some advise and list experience on using this or other disk
subsystem benchmark programs properly with or without a GUI ?
Test system in this case is a Compaq DL360 with 2 to 4 Gig DRAM and qty (2)

Unexplained reboots in DRBD82 + OCFS2 setup
We're trying to setup a dual-primary DRBD environment, with a shared
disk with either OCFS2 or GFS. The environment is a Centos 5.3 with
DRBD82 (but also tried with DRBD83 from testing) .
Setting up a single primary disk and running bonnie++ on it works.

7.0-Release and 3ware 9550SXU w/BBU - horrible write performance
Hi,
I've got a new server with a 3ware 9550SXU with the
Battery. I am using FreeBSD 7.0-Release (tried both
4BSD and ULE) using AMD64 and the 3ware performance
for writes is just plain horrible. Something is
obviously wrong but I'm not sure what.
I've got a 4 disk RAID 10 array.
According to 3dm2 the cache is on. I even tried

ext3 performance with hardware RAID5
I'm setting up a new fileserver. It has two RAID controllers, a PERC 3/DI
providing mirrored system disks and a PERC 3/DC providing a 1TB RAID5 volume
consisting of eight 144GB U160 drives. This will serve NFS, Samba and sftp
clients for about 200 users.
The logical drive was created with the following settings:
RAID = 5
stripe size = 32kb
write policy = wrback

benchmark results
I've had the chance to use a testsystem here and couldn't resist running a
few benchmark programs on them: bonnie++, tiobench, dbench and a few
generic ones (cp/rm/tar/etc...) on ext{234}, btrfs, jfs, ufs, xfs, zfs.
All with standard mkfs/mount options and +noatime for all of them.
Here are the results, no graphs - sorry:

Linux tool to check random I/O performance
we just purchase new I/O card and like to check I/O performance.
for sequence I/O performance test we can use "hdparm -t /dev/xxx"
bur for random I/O performance test which Linux command I can use?
** our environment does NOT allow install third party software..

Xen reboots on dom-U disk stress...
Hi all
I tried to run bonnie++ disk stresser in dom-U, who''s disk is backed
with non-local (on nfs) loop-back file.
The machine rebooted pretty quickly.
So, how do I tell what''s barfing? Is it Xen? Is it dom-0 (nfs or loop-back)?
I looked in dom-0''s /var/log/messages and didn''t see any obvious record
of a dom-0 whoopsie (but is that the right place to look

a comparison of ext3, jfs, and xfs on hardware raid
I'm setting up a new file server and I just can't seem to get the
expected performance from ext3. Unfortunately I'm stuck with ext3 due
to my use of Lustre. So I'm hoping you dear readers will send me some
tips for increasing ext3 performance.
The system is using an Areca hardware raid controller with 5 7200RPM
SATA disks. The RAID controller has 128MB of cache and the disks

Help understanding some benchmark results
G''day, all,
So, I''ve decided to migrate my home server from Linux+swRAID+LVM to Solaris+ZFS, because it seems to hold much better promise for data integrity, which is my primary concern.
However, naturally, I decided to do some benchmarks in the process, and I don''t understand why the results are what they are. I though I had a reasonable understanding of ZFS, but now

Kernel oops when running bonnie++ on btrfs
I wanted to see how btrfs compares to other filesystems so I have been
running bonnie++ on it. While the results are good(much faster then
ext2) every once in awhile I get a kernel oops. I am testing on xubuntu
8.10 with the 2.6.27-7-686 kernel using the latest git sources. Most of the
time the oops happens within 20min of running bonnie++ but sometimes it
takes a few hours. This happens with and
