I wonder if this could be a glusterfs bug:
I mount /mnt from glusterfs, run vi /mnt/a and I kill -SEGV glusterfsd on the
client while /mnt/a is open.

I restart glusterfsd on the client, and then:
rm /mnt/a
=> Runs fine

touch /mnt/a
=> [2010-09-30 09:51:47] W [fuse-bridge.c:1679:fuse_create_cbk] glusterfs-fuse: create(/a) inode (ptr=0xbb90f2c0, ino=23, gen=2) found conflict (ptr=0xbb90f260, ino=23, gen=90657)

ls -l /mnt/a
ls: /mnt/a: No such file or directory
=> [2010-09-30 09:51:55] W [fuse-bridge.c:725:fuse_attr_cbk] glusterfs-fuse: 12: STAT() /a => -1 (No such file or directory)

ls /mnt|grep a
=> readdir see the file but getattr does not, because it used the ino for the 
removed file, which it obtained by lookup.

Is that a bug in glusterfs or in NetBSD FUSE emulation? Any hint welcome. 
I am still running 3.0.5, this may be part of the problem.
