fstab, Unusual Behavior Of “missing UUID”

CentOS 2 Comments

I have the following as the last line of my /etc/fstab file on a computer running CentOS6.4..

UUID;550884-8d05-41a5-a205-17b6d7269dd1 /mnt ext3 rw,suid,dev,exec,noauto,nouser,async 0 2

The UUID refers to an ext3 partition of a removable USB drive.

If the USB drive is not plugged into the computer the computer will not boot. It seems that this is the incorrect behavior since “noauto” means there is nothing to mount. I noticed this situation since an almost identical /etc/fstab on a Fedora 18 computer will boot without the USB drive being plugged in.

The reason this is important to me is that I want to plug my USB drive into a running computer and then mount it with “# mount /mnt” so I can do backups.

Thank you, Joe Hesse

    This final “2” should be a zero. You’ve told the system to check the disk at boot time. If the disk doesn’t exist then fsck will abort and the machine will drop to single-user mode prompt.
