[MontelLUG] Lessfs

[Samuele]

Qualcuno ha esperienze con il suddetto file system.
Sono riuscito ad installarlo su una lenny (dopo qualche accrocchio con i
repository di sid e la compilazione a mano).
Sia sdb1 una partizione su un disco apposito addetto a backup e /mnt/sdb1 il
suo mountpoint creato su sda1.
Dentro a /etc/lessfs.cfg ho impostato i vari puntamneti a /mnt/sdb1/less/mta
e /mnt/sdb1/less/mda

lancio:
# lessfs /etc/lessfs.cfg /mnt/copie
faccio un
# dd if=/dev/zero of=/mnt/copie/test bs=1M count=10

df prima e dopo del dd e mi trovo occupato lo spazio su sda1 invece ceh
sdb1.

Dai log nulla di strano.
Dove mi sono intortato?

Allego lessfs.cfg
