2.4.25 XFS can't create files

2.4.25 XFS can't create files

[Carsten Gaebler]

Hi there,

I have somewhat of an esoteric problem. I can create an XFS on an 
external fibre channel RAID attached to an LSI fibre channel card 
(Fusion MPT driver) but I can't create files or directories on that 
filesystem (Permission denied). ext2/ext3 work fine on the same 
partition, so I suspect this is an XFS+MPT issue.

Here's what I tried:

sq22:~# mkfs.xfs /dev/sdb2
meta-data=/dev/sdb2     isize=256    agcount=140, agsize=1048576 blks

          =              sunit=0      swidth=0 blks, unwritten=0

drwxr-xr-x    2 root     root         4096 Apr  2 09:26 /mnt/xfs/
sq22:~# mount -t xfs /dev/sdb2 /mnt/xfs/
sq22:~# mount | grep xfs
/dev/sdb2 on /mnt/xfs type xfs (rw)
sq22:~# ls -ld /mnt/xfs/
drwxr-xr-x    2 root     root            6 Apr  2 09:25 /mnt/xfs/
sq22:~# touch /mnt/xfs/foo

sq22:~#

I suspect it's not MPT related.  I'm not farmiliar with stock 2.4.25
but assume the XFS merge went OK and everything is sane.  Any chance
you can test with a CVS kernel from oss.sgi.com to rule out the
(probably minor) differences there?

strace shows open/creat failing?  there are also no ACLs and/or
security modules involved are there?

The SGI kernel works fine. Thanks for the hint.

> strace shows open/creat failing?

Yes.

open("/mnt/xfs/foo", O_WRONLY|O_NONBLOCK|O_CREAT|O_NOCTTY|O_LARGEFILE, 
0666) = -1 EACCES (Permission denied)

Nope.

Thats very odd - the SGI CVS 2.4 kernel (that you reported
working) is also at 2.4.25, and there's nothing in the XFS
fixes/updates there that might be the cause of this, AFAICT.
ACLs are not in Marcelo's tree, but that is unlikely to be
the cause here (both cases are well tested).  The only other
thing I can suggest is a liberal sprinkling of printks on
the sys_open path, till you find the spot thats returning
this error..

cheers.
