issue lessfs: doesn’t seem to actually mount the lessfs

Hi,

I’m having an issue with lessfs, I can’t figure what I’m doing wrong, but it doesn’t seem to actually mount the lessfs, but doesn’t output any error nor messages.

Config file /etc/lessfs/alex.cfg available at http://pastebin.com/P335Wj6B

[root@arch64vm ~]# mkdir -p /data/{dta,mta}
[root@arch64vm ~]# mklessfs -c /etc/lessfs/alex.cfg

[root@arch64vm ~]# mkdir /lessfs
[root@arch64vm ~]# lessfs /etc/lessfs/alex.cfg /lessfs

No error, no output, but:

[root@arch64vm lessfs]# echo $?
4

Nothing new in dmesg.
/var/log/messages shows:

Jan 11 21:46:10 localhost lessfs[6822]: Blocksize = 131072 bytes
Jan 11 21:46:10 localhost lessfs[6822]: MIN_SPACE_CLEAN is not set, lessfs runs -ENOSPC when reaching MIN_SPACE_FREE
Jan 11 21:46:10 localhost lessfs[6822]: The selected data store is chunk_io.
Jan 11 21:46:10 localhost lessfs[6822]: Lessfs transaction support is enabled.
Jan 11 21:46:10 localhost lessfs[6822]: config->blockdata = /data/dta/
Jan 11 21:46:10 localhost lessfs[6822]: compression = none
Jan 11 21:46:10 localhost lessfs[6822]: Threaded background delete is disabled
Jan 11 21:46:10 localhost lessfs[6822]: Hash MHASH_TIGER192 has been selected
Jan 11 21:46:10 localhost lessfs[6822]: Lessfs uses a 24 bytes long hash.
Jan 11 21:46:10 localhost lessfs[6822]: cache 2048 data blocks

[root@arch64vm ~]# mount | grep less
[root@arch64vm ~]# (nothing)

So, no lessfs mounted.

[root@arch64vm ~]# cd /lessfs/
[root@arch64vm lessfs]# df .
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda3 7060308 5937076 764584 89% /

Anything I could be doing wrong?
