Hello :)
I may very well be retarded here, because I understand very little of
both the aufs man page and the examples included therein. If I am,
please excuse me, I assure you I've googled intensely.
Thing is, I simply cannot get anything to mount with aufs since I
upgraded from Ubuntu Saucy to Utopic yesterday ("upgrade" here meaning
that I reinstalled from scratch and is setting it up again from
scratch).
My use case is extremely simple — I have a bunch of directories, each
representing an offline backup drive, that I want to unite in a
read-only folder and share via Samba. In saucy, I could do this with:
/bin/mount -t aufs -o
dirs=/titanic/Downloads/Processed=ro:/titanic/Volumes/XD001=ro:/titanic/Volumes/XD071=ro
none /Archive
(I've shortened the command down, it actually contains 71 volumes from
XD001 to XD071).
This would mount perfectly in Saucy, but it seems something is
different now, because now I get,
mount: wrong fs type, bad option, bad superblock on none,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
Syslog now says that, "aufs au_opts_verify:1530:mount[2700]: first
branch should be rw".
Prepending the options list with ro, the syslog rw error disappears,
while still logging "aufs test_add:293:mount[2706]: uid/gid/perm
/titanic/Volumes/XD071 1000/1000/0755, 1000/1000/0777" for each
member. I still get the same "mount: wrong fs type, ..." error,
though, and nothing is mounted. There are no other messages to help
figure out what's wrong.
Trying the first example from the manpage,
$ mkdir /root/a /root/b /root/c
$ mount -v -t aufs -o br:/root/a:/root/b none /root/c
mount: wrong fs type, bad option, bad superblock on none,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
Syslog and /var/log/messages are both completely silent.
What's going on here? Am I really that retarded? :)
TIA,
Daniel
