-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear all! I have a question regarding luks on lvm: Currently I am running LUKS on a 6-disk raid 5, where every disk has 1 primary partition that takes part in the raid. So far no problems. But I'm running out of space. So I would like to buy 2 new drives, set them up as a raid 1 (for convenience i would add the whole drives to the raid without creating partitions on them), add the raid as (the only) volume to a lvm volume group and put several partitions on the lvm: unencrypted ones for root, home ... and one encrypted to hold critical data. Then I intend to copy over the data from the 6 disk encrypted raid5 to the new drives' encrypted logical partition and dismantle the 6 drives. I think such a setup is perfectly valid, but is there any concern putting luks on a virtual partition in a volume group consisting of a raid1? Do I need to take something special into account, like setting up lvm in a special way (certain block size...) to make it work smoothly with luks? Do I need to tell luks some additional information such that it is installed on lvm? Is such a setup as stable as putting luks on real partitions? Should I fill the whole disk with /dev/urandom or just the partition that will hold the luks volume? What if I add another disk (or raid volume) to the volume group in order to expand the space in future? Will that disturb luks? I have done a smooth raid5 expansion from 4 to 5 to 6 disks in the past followed by a luks expansion and an ext3 expansion, but never an lvm expansion... Thanx for help, regards, Wolfgang - -- Wenn die meisten sich schon armseliger Kleider und Möbel schämen, wieviel mehr sollten wir uns da erst armseliger Ideen und Weltanschauungen schämen?
