What filesystem on the server are you exporting?

xfs.
/dev/sda1 on / type xfs (rw,noatime)

Nothing special, thoughts?

Are there a lot of files in the directory you're exporting?  It looks
like cookie 10272 is mapped to multiple files.

I thought xfs is immune to readdir loops!?
Is your export directory really located directly within / on /dev/sda1?

Hi,

I was sharing out a directory on the NFS server:
/d1         192.168.0.0/24(async,rw,no_root_squash,no_subtree_check,fsid=1)

Should I share out / instead?
Is this a known problem?

$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1              30G   13G   18G  43% /
tmpfs                 2.0G  8.0K  2.0G   1% /lib/init/rw
udev                   10M  192K  9.9M   2% /dev
tmpfs                 2.0G     0  2.0G   0% /dev/shm
$

Justin.
