For years this type of thing drove me nuts also. LVM is your friend
here (and in may other places also). fstab is as simple as:
/dev/VolGroup00/LogVol00 / ext4 defaults 1 1
Of course you can be much more creative and use volume group and logical
volume names that suit you.
If you happen to have non-LVM partitions (boot for example) UUID can
solve those too:
UUID=2ed29516-67a5-46dd-9e13-ea82624822fc /boot ext4 defaults
1 2
If you need to find the UUID run blkid. Took me a while to figure that
out!
$ blkid
/dev/sdb1: UUID="cbc0edfb-8b07-4c3f-8db0-f4274075f239" TYPE="crypto_LUKS"
/dev/sda1: UUID="30e21302-cabb-42d0-9ba2-da72463853a5" TYPE="ext4"
/dev/sda2: UUID="948a228f-13ec-462e-9e9e-fa9b4c4bd2e0" TYPE="crypto_LUKS"
/dev/sda3: UUID="857c8618-2461-4dfc-b5bb-69949a804c6d" TYPE="crypto_LUKS"
/dev/mapper/luks-948a228f-13ec-462e-9e9e-fa9b4c4bd2e0:
UUID="45e927e7-45d2-4363-bad1-fb91ea9dc992" TYPE="ext4"
/dev/mapper/luks-857c8618-2461-4dfc-b5bb-69949a804c6d:
UUID="e863f1db-c86a-4e12-a2ee-d2528b52656c" TYPE="swap"
/dev/mapper/lin-bak: LABEL="lin-bak"
UUID="ec7f0cec-e672-4ca3-8736-8b7e23b5ffc9" TYPE="ext4"
But really, LVM is the best thing since sliced bread. For example when
you run backups (you do, right?)
I am obsessive. That is what caused all this. The rotating
removable drives are for backup. And there are several backup
sets on each removable drive. Two other types of backup too.
then you absolutely want to be running
them against a snapshot rather than a live FS and LVM makes this easy.
Never really cared for LVM. Always used the direct partition approach.
