I lost some files; even those not used for a long time.
It is possible that last shutdown was unclear.
After xfs_repair I got lost+found full of files deleted some time ago.
I actually had to run xfs_repair (2.5.3)  few times because it was 
'segfaulting'.

Hi there,

What XFS blocksize are you using, and what is your page size?
There are known issues when using blocksizes smaller than the
page size in the 2.6 XFS code at the moment.

Feel free to open bugs for this and your repair problems on the
XFS site on oss.sgi.com; the gdb backtrace of the failed repair
attempts will be useful as well.

thanks.

I believe there was a post this past weekend about block sizes (or maybe
fragment sizes) on the Opteron.  It wasn't with XFS I'm pretty sure.  I
tried searching for it, but can't find it again.

I'm going to start playing with an Opteron pretty soon.  I will be using
XFS.  What are the recommended settings when creating file systems?

Use the xfs_info command on a mount point:

meta-data=/xfs                   isize=256    agcount=8, agsize=131031
blks
         =                       sectsz=512  
data     =                       bsize=4096   blocks=1048241, imaxpct=25
         =                       sunit=0      swidth=0 blks, unwritten=1
naming   =version 2              bsize=4096  
log      =internal               bsize=4096   blocks=16384, version=1
         =                       sectsz=512   sunit=0 blks
realtime =none                   extsz=65536  blocks=0, rtextents=0

bsize=4096 is the vlock size.

  Hi Nathan, and congratilations for the SGI work.

  Now i have a Mandrake with the 2.5.75 kernel and XFS in
all partitions. The filesystem looks work very well.

  I am planning install 2.6.0-test3 when it comes and i wanna
ask you: how can i know what blocksize am i using?, and how
know what is the page size in my system?.

  Thanks you, very much, in advance.

  Regards.

  Jose.
