The new XFS file system code from SGI is now available on the CentOS-4 Developer's testing site.
You can install the dev-testing repo from here:
http://dev.centos.org/centos/4/
And putting the CentOS-Testing.repo file in your /etc/yum.repo.d/ directory.
You can then install the new xfs module on the standard centos i686 or x86_64 kernels.
You have to pick the proper kernel that you are running. ------------------------------------------------------------------- Here is the command that would install the XFS module and the minimum required XFS tools:
yum install dmapi xfsprogs xfsdump kernel-module-xfs-`uname -r`-0.1-1 --------------------------------------------------------------------
This will install the just released XFS code from SGI.
BUT ... this code is still not 100% working with 4K stacks (which all EL 4 and FC 3/4/5 kernels currently use). A note from SGI on this code:
################################################################# # # # NOTICE # # This xfs module rpm has been provided for testing purposes # # only. It is believed to be functional, but it has not been # # heavily tested. In particular, you may have issues with the # # 4KSTACKS option on RHEL4 ia32 kernels, depending on your IO # # hardware, layering, nfs usage, etc. # # # # Please do NOT report any problems with this module, or with # # the kernel when this module is loaded, to Red Hat. # # You may report issues to the linux-xfs@oss.sgi.com list. # # (Please also report successes!) # # # #################################################################
You may also report successes and failures to the CentOS-Devel list.
I installed this and ran 15 full tests with Bonnie++ on the XFS partition without any errors. I was using a PATA drive and a pIII 800 Mhz PC.
------------------------------------------------------ NOTE: This will not run currently with the CentOS Plus kernel, as XFS is already compiled as a module on that kernel.
After some testing here (if all goes well), a new CentOS Plus kernel w/out XFS will be compiled and this code will also be moved (with instructions) to the CentOSPLus repo. ------------------------------------------------------- NOTE: After completing the install of the XFS code, you should edit /etc/yum.repos.d/CentOS-Testing.repo and set the line:
enabled=1
TO
enabled=0
to turn off the testing repository for CentOS-4 until you want to upgrade items from it again. This repo will get other Alpha/Pre Release type code in it and you would not want to accidentally overwrite stable CentOS packages during updates. --------------------------------------------------- Thanks, Johnny Hughes CentOS-4 Lead Developer
