I stay away from LVM because I simply am not confident I can repair it
in case of disasters. As simple as that: I have not invested time in
learning it in depth, and it is delicate to recover (first track lost,
entire disk lost). Well, there are backups to cover that.
There are important advantages.
You can easily add space to partitions.
You assign some initial space, and leave ample space out. As you need
more space to a partition inside the LVM (ok, not a partition, has
another name), you simply add it from the free space pool. You need that
empty space pool for this important feature. You can even add space from
other disks (adding vulnerability, too).
(On the other hand, traditional partitions can be located in case of
disaster, by gpart. LVM spaces, can not)
Another important use case for LVM is full disk encryption. It is done
by YaST. There is a boot partition, an encrypted LVM container, and
inside it all the “partitions”. You only enter the passphrase once.
(It would be possible to encrypt the entire disk with discrete
partitions, but YaST does not support this method).
My main recommendation: unless you really understand it, do not use it.
