[Unionfs] (no subject)

[Stan Franker jr]

when issueing the command: mount -t unionfs -o dirs=/mnt/disk1=ro:/mnt/disk2=ro unionfs /ftp/site/archive

i get:

mount: wrong fs type, bad option, bad superblock on unionfs-mv,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

dmesg output is:

NET: Registered protocol family 10
lo: Disabled Privacy Extensions
IPv6 over IPv4 tunneling driver
eth0: no IPv6 routers present
Installing knfsd (copyright (C) 1996 okir at monad.swb.de).

unionfs_read_super: error while parsing options (err = -22)
unionfs_read_super: error while parsing options (err = -22)
unionfs_read_super: error while parsing options (err = -22)

i'm using

Linux debian 2.6.18-4-686 #1 SMP Mon Mar 26 17:17:36 UTC 2007 i686 GNU/Linux

with unionfs-1.4. Is this a compatibility issue? According to http://www.am-utils.org/project-unionfs.html unionfs-1.4 is compatible with kernel 2.6.18.8 which is obviously newer then what i am using. 

regards,

Stan
