[mythtv-users] Question about fstab - how to mount and umount by UUID?

[Don Brett]

This may be a little off-topic; I have a strange linux problem. Working 
on a new Mythtv build, I have multiple drives installed...

Using all the Sata jacks:
Sata1: SSD for boot, 120Gig
Sata2: WD 2.0T (terra byte)
Sata3: Samsung 2.0T
Sata4: WD 1.5T
Sata5: WD 1.0T

Linux sees them as this (very strange, skips d, e, f, g)
/dev/sda
/dev/sdb
/dev/sdc
/dev/sdh
/dev/sdi

I've messed around with the bios boot order and gotten some different 
results, but nothing puts them in order.  I thought it might be better 
to set up fstab with UUID's, but I don't see any way to manually 
mount/umount each drive, individually .  Google only shows "mount -a", 
which I assume mounts everything in fstab.  What do you suggest?

Here's my fstab; the installer setup "/" and "swap"; I added the 
remaining four.

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type> <options>       <dump>  <pass>
