Why do I have to manually run a mount -a to have the remote CIFS filesystem to be mounted?
There must be some misconfiguration in the fstab, which is the following:
Code:

/dev/sdb2               /               ext3    noatime         0 1
/dev/sdb3               /home           ext3    noatime         0 0
#/dev/sdb1              /boot           ext3    noatime         0 0
/dev/sr0                /mnt/cdrom      auto    noauto,ro       0 0
//192.168.1.5/Volume_2  /mnt/nas/volume_2 cifs  auto,username=fulvio,password=,iocharset=utf8   0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
#  use almost no memory if not populated with files)
shm                     /dev/shm        tmpfs   nodev,nosuid,noexec     0 0


Thanks a lot, Fulvio

You did not mark your network filesystem as _netdev, so it is mounted before the network is available. This fails.

Code:

//192.168.1.5/Volume_2  /mnt/nas/volume_2 cifs  auto,username=fulvio,password=,iocharset=utf8   0 0


I hope, you ereased the password for security reasons, when posting. Otherwise, cifs wouldn't know the password and the mounting will fail. I don't know about the _netdev mark, but I do not use that mark, when connecting a cifs share at boot. here is my example:

Code:

//server/share   /mnt/backup   cifs      defaults,auto,credentials=/etc/.smbpasswd   0   0


In my example, the credentials are stored in the .smbpasswd file. You can verify it in this [1] link.

I've tried adding _netdev and the behaviour has not changed.

The share is on a private nas and readonly, but the lack of password shouldn't be a problem as the command mount -a is working fine, and also on the wiki ubuntu page at the link it seems like the same configuration with username "guest" without a password is mentioned as a configuration that is supposed to work.

Another very annoying issue is that when i run the mount -a the system can't perform the entire shutdown process: it blocks trying to unmount the /home filesystem without success.

I really don't know what to check to solve the problem
