Hi,
My NFS linux server exports via NFS a directory built using unionfs. My
client linux box imports this NFS directory without problem but when it
uses it in a union (always via unionfs) I obtains the following error
when I trie to access it :
Operation not permitted !
I carried out my tests with several versions of unionfs (including on
the last snapshot), with or without the definition of NFS_SECURITY_HOLE,
with or without rw option for NFS. My kernel is "Linux lutin 2.6.14-g2
#3 PREEMPT Fri Nov 11 11:50:15 CET 2005 i686 GNU/Linux" (both server and
client).
Below the result of the export and mounts :
Server side (192.168.114.1):
--------------------
# mount
...
none on /mnt/sda12/mktx/unionfs/qemu1 type unionfs
(rw,debug=1,dirs=qemu1=rw:x11=ro:noudev=ro:common=ro:kernels=ro:update=ro:deb=ro)
..
# exportfs -v
...
/mnt/sda12/mktx/unionfs/qemu1
192.168.200.2(rw,async,wdelay,no_root_squash,fsid=1)
...
Client side (192.168.200.2) :
--------------------
# mount
...
192.168.114.1:/mnt/sda12/mktx/unionfs/qemu1 on /nfs type nfs
(rw,v3,rsize=8192,wsize=8192,hard,udp,nolock,addr=192.168.114.1)
none on /slash type unionfs
(rw,dirs=/memory=rw:/nfs=rw,debug=18,delete=all,copyup=preserve)
...
# ls /slash/etc
ls: /slash/etc: Operation not permitted
Is possible to use in a union a directory imported by NFS resulting him
even from a union ?
Any help would be appreciated!
