I want a 2nd hard drive to mount at boot
I have this in /etc/fstab
UUID=7726e231-4373-451d-8588-930becd772c6 /home/server/common ext4 0 1
When starting I get an error, did I misconfigure the line?
Look at the top of /etc/fstab. It should have a line like this:
# Device Mountpoint FStype **Options** Dump Pass#
Your mount line has these:
# Device Mountpoint FStype Options Dump Pass# UUID=7726...d772c6 /home/server/common ext4 0 1
Notice the lacking value for the field options, which means that it gets parsed as:
# Device Mountpoint FStype Options Dump Pass# UUID=7726...d772c6 /home/server/common ext4 0 1
And options 0
is invalid.
I would suggest the correct entry should be as follows:
UUID=7726e231-4373-451d-8588-930becd772c6 /home/server/common defaults ext4 0 1
