Thanks for the news. I was wondering if in the release 1.4
you might want to support "Samba/Windows" NonPosix mandatory
Locks (mount -o mand ..) but that's for the future.
I'm trying to use the "glusterfs" cluster from Aix. I tried
Cifs but it was unsuccessful (cannot avoid caching), so I'm
going back to the NFS vers=3 (NFS vers=4 is too instable
And I have a specific problem with glusterfs.
When I exported the filesystem under linux FC4:
and mount it locally:
mount -o vers=3 localhost:/export/fs2 nfs1
I encounter the following problem:
(-- pts/39) touch /gfs/nfs1/essai
(-- pts/39) ls -lrt /gfs/nfs1/essai
-rw-r--r-- 1 fturi ft 0 Apr 5 17:10 /gfs/nfs1/essai
(-- pts/39) ls > /gfs/nfs1/essai
ls: write error: Operation not permitted
I enabled the trace and basically I see only fuse_gattr and
fuse_gattr_cbk in the debug trace.
I know that fuse_open is being called (according to gdb)
and nothing else.
I have the same problem with release 1.2.3, 1.3.2pre2 and tla
I have the same problem with Linux NFS client and Aix NFS
client (in Aix the strerror says: Not owner). I also tried
different combinaison of exports (no_root_squash .. anon_uid
...) and users and always get the same result.
I suspect something that the NFS deamon doesnt like in the
attributes returned or a problem in open.
Do you have any hint what and where I could check to debug
this behavior ?
Happy Easter, FT
