Zero problems here after upgrading a bunch of servers. I guess the majority of 
users without problems is just not as loud. :-)

Thank you CentOS team for the good work!

Works great using the XFS Module from CentOSPlus. We use it for the data 
partition of our fileserver.

You might want to try audacious. It looks and feels a lot like XMMS or WinAmp, 
very different from Totem, Rhythmbox or Amarok. It uses modern libs and is 
actively maintained. It is the perfect XMMS drop-in replacement. It's in 
Fedora, and I think RPMs for CentOS/RHEL are in DAG.

Re: [CentOS] NFS filesystem recommendations please (and problems with XFS)

Just to add some positive feedback: I implemented XFS on an x86_64 box running 
CentOS around here. The machine is an NFS, Samba and Emailserver (kolab, that 
means postfix + cyrus imapd). The machine has a Hardware SCSI RAID with 8 10k 
U320 HDs. So far we had a minor issue with some small undeletable files that 
could be tracked down to a XFS bug (which is fixed by now). Other than that 
the box has been running rock stable. We started with CentOS 4.2 or 4.3 and 
are now at 4.5 via continuous yum updates.

Before the machine went into production I had about two weaks for doing heavy 
benchmarking and some reinstalls. Using XFS and tuning the parameters of the 
RAID array gave a massive performance boost. I also tried tuning ext3 but got 
only about half the throughput than with XFS, so I decided to go XFS.

Of course these results depend on usage pattern, hardware, etc. So do your own 
benchmarks. I myself asked our heavies nfs users for their homedirs or parts 
of it and benchmarked by copying these around in parrallel. This was quite 
enlightening and much more useful than artifical benchmarks.

Andreas Micklei

For the sake of completeness: There is of course also a kmod-xfs for the 
centosplus kernel, in case you are running one. Obviously it's the one with 
the "plus" in it's name. Works absolutely well, just as the module for the 
standard kernel.
