Red Hat Bugzilla – Bug 207112
No XFS filesystem .ko or xfsutils in distro RFE
Last modified: 2007-11-30 17:07:34 EST
Description of problem:
Once again, XFS is not included in the standard distribution. Suse has an
Enterprise distro, they include XFS in theirs. All the Super Computer sites use
XFS. Why not RedHat? Centos provides XFS rpms.
Under 2.6.17 and 2.6.18 EXT3 yeilds ~680MB/Sec reading 4 hardware raid0 devices.
(in this case either hardware raid0 sata drives, or LSI SAS raid drives). Using
XFS I obtain 1.2GB/Sec from the identical hardware. This is 99% line rate.
I get at best 200MB/Sec write rates with EXT3, but 1.04GB/Sec with XFS. What
gives? Do I have to roll my own kernel and fustrate the security types who want
*ONLY* a standard redhat kernel, or just discard the FibreChannel connections
just to get a HUGE performance increase? We are in the business of HIGH
performance. I cannot justify spending $2,500 on a distro that will not provide
one kernel module and 2 support RPMS. XFS is standard in the linux distro.
I'm not asking for /root to be XFS, just data partitions.
