Filesystem Performance
By: rekha singh | 13 May 2010 11:53 am
Hi All, I am new with red hat, I was Solaris admin and now my company start using Red hat. they ask my configure red hat with Equal Logic array
which I did, I managed to configure the iscsi and multipath. but my issue is the I/O performance
My question here is
- which file system I should use to get the best performance
- shall I use LVM or no.
my file system is less than TB
At Solaris I use ZFS file system but in Linux I don't know which file system is the best
Thanks
CommentsUsing redhats logical volume manager is good. I have not seen any shops (evne with plenty of money) who buy third party volume managers for RedHat.
Scroll down and you will find GFS and LVM manauals in pdf...Also redhat system admin manuals.
my file system is less than TB
At Solaris I use ZFS file system but in Linux I don't know which file system is the best
Thanks

I'd also like to add a couple things... First, LVM is NOT a filesystem. LVM is a volume management system that allows you to dynamically allocate storage across mutiple storage systems. LVM really doesn't care what filesystem you use on your volumes. That being said, Dan is right, go and read the docs at Red Hat.
Also, you may want to look at this:
Its a comparison article showing some performance testing between
EXT3, EXT4, XFS, BTRFS and NILFS2
Good Luck,

Hi, which I did, I managed to configure the iscsi and multipath. but my issue is the I/O performance . My question here is
Its the matter of performance of "Filesystem or Application " ?. First you have to
identify the exact issue, who is running with poor performance! . I am not sure the present filesystem you are using and how you are testing the Filesystem performance.
Anyways, I would suggest you to check the following
* Run the same application in Local filesystem n check.
* Use latest kernel and check.
which file system I should use to get the best performance
I would suggest EXT3
shall I use LVM or no.
LVM is not a Filesystem, that is a container . ! LVM is capable to manage filesystems you have created on top of it.
my file system is less than TB
Then I would suggest you stick on EXT3
Red Hat is now shipped with EXT4 filesystem which is advanced one of EXT3 .
But not yet started Supported in Production environment as it is Technology Preview.
