I have the following /etc/fstab:

# /etc/fstab: static file system information.
# <file system> <mount point>     <type>      <options>                  <dump>  <pass>
proc            /proc             proc        defaults                   0       0
/dev/md1        /                 ext3        defaults,errors=remount-ro 0       1
/dev/md0        /boot             ext3        defaults                   0       2
/dev/md5        /home             ext3        defaults                   0       2
/dev/md3        /opt              ext3        defaults                   0       2
/dev/md6        /tmp              ext3        defaults                   0       2
/dev/md2        /usr              ext3        defaults                   0       2
/dev/md4        /var              ext3        defaults                   0       2
/dev/md7        none              swap        sw                         0       0
/dev/sdc        /home/httpd       ext3        defaults                   0       2
/dev/hda        /media/cdrom0     udf,iso9660 user,noauto                0       0
/dev/sdc1       /mnt/usb/backup-1 auto        defaults                   0       0

I am unable to get /dev/sdc/, an internal SATA hard disk, to mount at /home/httpd/ on reboot. The /home/httpd/ directory exists.

Mounting via mount -t ext3 /dev/sdc /home/httpd works just fine.

Mounting via mount -a generates the following error message:

mount: you must specify the filesystem type

This is, incidentally, the same message that I see while booting. The error message goes away if I comment out the line in fstab starting with /dev/sdc.

what exactly is /dev/sdc? internal hard drive? USB drive? removable card reader device? – quack quixote Jun 14 '10 at 15:31

There is an error in your fstab: you cannot simultaneously have a valid filesystem both on /dev/sdc and /dev/sdc1. One of these commands (or maybe two) will definitely fail, and as mount /dev/sdc works fine, the failing one is second. Also it probably prevents second mount from executing; while I don't know exactly, it should work. And if you want to check a line in fstab for correctness, don't specify the mountpoint: this will force mount to lookup it (and other options) in fstab effectively verifying your setup.
