Benchmark Disk IO
What is the best way to benchmark disk IO?
I'm looking to move one of my servers, which is rather IO intense. But
not without first benchmarking the current and new disk array, To make
sure this isn't a full waste of time.
thanks

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

poor read performance
I am seeing what seems to be a notable limit on read performance of an
ext3 filesystem. If anyone could offer some insight it would be helpful.
Background:
12 x 500G SATA disks in a Hardware RAID enclosure connected via 2Gb/s FC
to a 4 x 2.6 Ghz system with 4GB ram running RHEL4.5. Initially the
enclosure was configured RAID5 10+1 parity, although I've also tried
RAID 50 and currently RAID 0.

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

3Ware 9550SX and latency/system responsiveness
Dear list,
I thought I'd just share my experiences with this 3Ware card, and see
if anyone might have any suggestions.
System: Supermicro H8DA8 with 2 x Opteron 250 2.4GHz and 4GB RAM
installed. 9550SX-8LP hosting 4x Seagate ST3250820SV 250GB in a RAID
1 plus 2 hot spare config. The array is properly initialized, write
cache is on, as is queueing (and supported by the drives). StoreSave

benchmarking large RAID arrays
I'm just wondering what folks are using to benchmark/tune large arrays
these days. I've always used bonnie with file sizes 2-3 times physical
RAM. Maybe there's a better way?

recommend benchmarking SW
Hey folks,
We've got some new hardware and are trying to figure out what best to
do with it. Either run CentOS right on the bare metal, or
virtualize, or several combination options. Mainly looking at :
- CentOS on bare metal
- CentOS on ESXi 4.0 with local disk
- CentOS on ESXi with 1 VM running Openfiler to serve disk to other VMs
And want to benchmark these 3 scenarios

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

Finding performance bottlenecks
Tony?s performance sounds significantly sub par from my experience. I did some testing with gluster 3.12 and Ovirt 3.9, on my running production cluster when I enabled the glfsapi, even my pre numbers are significantly better than what Tony is reporting:

Before using gfapi:

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:

Bonnie++ run with RAID-1 on a single SSD (2.6.29-rc4-224-g4b6136c)
Hi folks,
For people who might be interested, here is how btrfs performs
with two partitions on a single SSD drive in a RAID-1 mirror.
This is on a Dell E4200 with Core 2 Duo U9300 (1.2GHz), 2GB RAM
and a Samsung SSD (128GB Thin uSATA SSD).

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.

zfs raidz1 and traditional raid 5 perfomrance comparision
Hi,
for zfs raidz1, I know for random io, iops of a raidz1 vdev eqaul to one physical disk iops, since raidz1 is like raid5 , so is raid5 has same performance like raidz1? ie. random iops equal to one physical disk''s ipos.

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...
