Dear friends,

I've been searching thorugh google for xfs configuration in REDHAT, finalyl i'am able to install xfsprogs, which i could make xfs filesystem on my new hardisk (1TB SATA), but the problem that rised was i could not mount it, it say xfs is not supported by the kernel... i try to locate the xfs.ko, i found out that my REDHAT doesnt have the module for xfs.

my question is, Could anyone gimme a hand please, how to enalb exfs in REDHAD, im currently having REDHAT 4 update 5, if you please give the step by step intruction on how to setup xfs in redhat, its urgents due to our new storage AX4-5 series which having 5 enclosure with 1TB disk each 60TB in total. I want to migrate from ext3 to xfs, because in my previous ext3 having lot of problem with FS crashed, suddently i have to fsck the FS, sometimes it doesnt work for RAID.


ty verymuch for the attention and help. I would really appriciate it.

First of all, do keep in mind that XFS isn't supported by RedHat.
If you value their support, don't use XFS.

This Howto should do the trick with RH stock kernels: http://landofthefreeish.com/how-to/e...-jfs-on-rhel5/

IMHO that's a very wrong reason for migrating from ext3 to xfs.
While xfs "mostly" works without fsck'ing (xfs has it's own tools), recovering when you do need it doesn't always work as well as with ext3, use it at your own risk.

If you're willing to drop RH support for this, you might want to look at ext4 (faster fsck'ing) as well.

Keep in mind that RH4 (a very, very old product, pre 2000?) and RHEL4 (currently supported) are two essentially unrelated products. Since you mentioned sata it is highly likely you are running RHEL4.

Ext3 is an extremely reliable file system. If you are having issues it is highly likely they have nothing to do with Ext3. Odds are that you are having an intermittent hardware issue (overload PSU, bad power, etc), have a bad RAID configuration, or some other non FS problem.

First of all i would like to thank you guys for the trouble posting your opinion and helping me on this matter,

@jens:
Yes i agree with you about the RHEL support for xfs, but i heard nowdays that they give support for xfs if you upgrade (subscribe). im not really sure thou, its just i found out some few blogs that stated it.
it seems silly really i dont believe it at first thou, but i tried this several times with my old storage DS3xxx which i configured the all the drive and formated in ext3, after that i tried to run JOB (sesmic JOB which basically IO process for write and read) i created 3TB FS with parted, then i succesfully created partition, then i formated with ext3, finaly i got 2xxxGB after 3 days the storage up and running, on the 4th day, users complained that they could not access the FS, i ran to server and check the status of FS on the "server", i dmesg i shows and IO /error when i try to create or copy file in to the FS it says readonly FS, ah ok i backed up then i reformated the FS, this time i got the same problem.
*** Running job is non stop process which means that there will be like more than 10 hosts will be using the disk for write and write, the file is as big as 2-10 GB per file... if i compare to SGi which xfs is their native FS, never crash and never have problem and i've been using it for like 2 yeras now.

@lazlow:

yup i agree with you for some reason, i tried to check wheter the kernel configuration is right or not, i try to modify the kernel, but still i have problem with the ext3 failed/crashed (read only FS) often i need to restart the server and it took me 1 hour to configure everything up and running.
