Howdy, I sort of started this on another thread but wanted to nail a few things down first. I'm wanting to encrypt some parts of my data on /home. This is what I got hard drive wise.
root@fireball / # pvs PV VG Fmt Attr PSize PFree /dev/sda7 OS lvm2 a-- <124.46g 21.39g /dev/sdb1 Home2 lvm2 a-- <5.46t 0 /dev/sdc1 Home2 lvm2 a-- <7.28t 0 /dev/sdd1 Home2 lvm2 a-- <7.28t 0 /dev/sde1 backup lvm2 a-- 698.63g 0 root@fireball / # I've done some checking on sizes of things I want to encrypt and am weighing options. I use LVM which should help make things easier. I've downloaded and printed some howtos regarding shrinking the file system and LVM thingys. It seems I need to shrink the file system while my /home partition is unmounted. Then move the data off whichever drive I want to remove and then remove the drive itself. After that I can encrypt the just removed drive and start moving files over, using rsync is my plan. I think that is the basic steps. My question now comes to this. When I encrypt one of the drives, can I then expand that drive with it being encrypted or is that not a option? I plan to encrypt two of the drives as one volume group and leave one other volume group as normal. I just want to be sure whether or not I can expand a encrypted LVM drive the same as a normal LVM since both uses LVM. I use cryptsetup commands to accomplish the encryption if that matters. So as a example, I start with one 7TB drive encrypted, move some data to it, then want to add either the 5TB or 7TB drive. Can I just expand it like a normal LVM or does it being encrypted change things? Thoughts? My remove steps look sensible? Expanding encrypted LVM possible? Dale :-) :-)
