[Swlug] using lvm for mirror

[Matt Willsher]

I was thinking the same thing about your replies Ben :) we’re both saying
the same tried and tested approach.

With any raid set up it, it’s recommended to test failure if possible - I
do that by pull the power or data cable  from one of the drives while in
use but that may be a little reckless.

With the 1TB you could allocate 100GB to a volume initially then add other volumes and grow them as needed. If you split the disks into partitions and put md on top of each of those and use directly you can’t easily change those sizes.
