Best mkfs.ext2 performance options on RAID5 in CentOS 4.2
I can't seem to get the read and write performance better than
approximately 40MB/s on an ext2 file system. IMO, this is horrible
performance for a 6-drive, hardware RAID 5 array. Please have a look at
what I'm doing and let me know if anybody has any suggestions on how to
improve the performance...

hardware issues? driver issues?
Got a bunch of servers from Penguin. Supermicro m/b's H8QG6. We put a 3tb
drive in for additional workspace for the users, and some of them won't
read, others will go for weeks, then spit out DRDY errors. lshw shows the
controller as an ATI SB7x0/SB8x0/SB9x0 SATA.
I did notice that it shows

[e2fsprogs-1.24] "fsck -A -a" fails on reboot
Dear Ted,
I upgraded e2fsprogs and util-linux to the latest versions, as per the
instructions on the "ext3 for 2.4" page, to make the switching between
ext2-only and ext3-enabled kernels seamless.
Now that if the filesystems have not been unmounted cleanly, due to a
power failure for example, "fsck -A -a" cannot continue after checking
the root filesystem on reboot, issuing

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.

Poor RAID performance new Xeon server?
I have just purchased an HP ProLiant HP ML110 G5 server and install ed

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)

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

e2fsck: bad magic number in super-block
Hi,
I'm on kernel 2.14.13-ac8 running Redhat 7.1. I've
successfully converted all my file system to ext3 and
is working fine for a couple of weeks. However, I did
a silly thing when I e2fsck (version 1.23) an ext3
/home partiction without umounting it. Now, I believe
my partiton super-block is corrupted and the system
wasn't able to mount /home. I tried as suggested to do

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

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:

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

Digital Audio (via EIDE ribbon cables) supported in Kernel in CentOS 5.0?
Hello: Will Digital Audio (via EIDE ribbon cables) be supported in the
Kernel in CentOS 5.0? I'm now using CentOS 4.4 on a Dell Dimension 2400
box (Celeron 2.6 GHz CPU). This is a dual boot box, rarely booted into
Windows XP, but when I do use Windows, and I place an Audio CD into the
DVD drive or CD-RW drive, I can hear the music. Using CentOS 4.4, I can
see that the software and hardware are

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

Status of SPARC64 port?
I was looking at the Sparc 64 4.7 or 4.8 port, wondering if its in any state
to put on my Solaris v100.
Just need the basics, eide, network, kbm,mouse, graphics (x).
A bonus would be support for the lom (light out management) features and the
flash card.
Reason for change is I HOPE that the math (ssl) performance is better on

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.
