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

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.

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...

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.

"bit already cleared" messages
There's been a lot of discussion in the past on
these somewhat-mysterious "bit already cleared"
messages appearing in the logs when using Ext3
file systems. Unfortunately, I didn't see a
conclusion to any of these threads.
We're still seeing these messages pop up occasionally
and fsck's of the file system reveal lot of orphaned
inodes and such.

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)

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.

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

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.

ext2 vs. ext3
Hi,
I just tested ext2 and ext3(2.4-0.9.6) with 2.4.8-ac8, using
bonnie++-1.01. The hardware is an old Pentium 100 box with 48M RAM and a
16.6MB/s EIDE harddrive. The test results(see attachment) show ext3 is a
lot slower than ext2 in most aspects. Does anybody get better results?

SSD diagnostics / test suite?
Hey folks,
I looked back through the list archives and there are surprisingly few
threads with "SSD" in the subject.
In my new job I've been handed over a number of things that were
outstanding with the previous Sys Admin, and one of them was an SSD
that was suspect. I just plugged it into a diagnostics laptop to use
the Linux Smart software to check it - and it all seems fine
