Hi,
Can you try some other command instead of 'ls'. I suspect that the 'ls -lia' filter is doing something strange. I wish to rule out this possibility.


Can you just do the following as well, meanwhile.

find <path> -name 'f4407c24c1f31d2304c8f8d4825*'

Regards,
Shailendra

Can you send xfs_info output?


This one is on 2.6.11 - x86 - partiton is on 72gb scsi drive:
meta-data=/xxxxx isize=256 agcount=16, agsize=4480124 blks
= sectsz=512 data = bsize=1024 blocks=71681984,
imaxpct=25
= sunit=0 swidth=0 blks, unwritten=1
naming =version 2 bsize=4096 log =internal bsize=1024 blocks=35000, version=1
= sectsz=512 sunit=0 blks
realtime =none extsz=65536 blocks=0, rtextents=0


with xfsprogs-2.6.13 compiled for i486

And 2.6.12-6 - x86_64 - partition is on MD raid1 - but  don't have
xfs_info on system - I'll have it tommorow - I guess ;) I have installed
xfsprogs-2.6.36 compiled for Intel's cpus with EM64T (nocona).

Hardware for both systems is not the same.


- some (very rarerly but they does) files appear like this on file
system:

$ ls -ila f4407c24c1f31d2304c8f8d4825*
237047122 -rw-r--r--  1 xxx yyy 6107 2006-01-16 23:33
f4407c24c1f31d2304c8f8d48258.dat.gz
237047122 -rw-r--r--  1 xxx yyy 6107 2006-01-16 23:33
f4407c24c1f31d2304c8f8d48258.dat.gz

Same problem appear on kernels 2.6.11 and 2.6.12.6 (x86 and x86_x64).
Have anyone already seen something like this?

Nope. Any ideas on how to reproduce it? Is NFS being used?


Yep - we are reproducing every day - but not intentialy. No NFS used - just writting and reading files from partition (with o_direct and without it). Maybe is just that we have about 5 milion files on those partitions.



cheers.
