Hello this is probably a somewhat advanced topic. I hope someone knows the answer.
I opted to go with the LUKS encrypted LVM setup using the Opensuse installer. I have:
LVG called system
/home (encrypted on system logical volume) dev-system-home (part of 'system' lvg)
/ (encrypted on system logical volume) dev-system-root (part of 'system' lvg)
swap (encrypted on system logical volume) dev-system-swap (part of 'system' lvg)
/boot (non encrypted boot partition) /dev/sdd1
The above are all on one 500 GB disk.
But I also have 3 other 80 GB disks which are unallocated. (actually I created another separate encrypted logical volume called data but let's pretend I haven't done that yet as I have no data on it and I can easily remove it -- I'd rather have it all added to the existed encrypted logical volume if this is possible without a lot of hassle)
Is it possible to add these three disks and the new space to my existing encrypted logical volume? So that instead of ~500GB in my /home I would have ~700GB in /home?
I know that if it were simply an unencrypted LVM I could do this. I also know that if it was all on one disk I could easily do it because I did something like it before:

Code:
--- Logical volume ---
LV Name /dev/system/home
VG Name system
LV UUID 90bJD8-UKCV-ngHp-X4jU-e3xX-DSjh-kjomH8
LV Write Access read/write
LV Status available
# open 1
LV Size 425.00 GiB
Current LE 108800
Segments 2
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 253:1
--- Logical volume ---
LV Name /dev/system/root
VG Name system
LV UUID y7iFhf-aWWt-fMu9-8nSu-PEV3-re3u-ACVnCr
LV Write Access read/write
LV Status available
# open 1
LV Size 20.00 GiB
Current LE 5120

Block device 253:2
--- Logical volume ---
LV Name /dev/system/swap
VG Name system

So basically I would like to take disks /dev/sda + /dev/sdb + /dev/sdc (currently on a separate "data" LVG) and add them in the 'system' lvg instead and expand the '/dev/system/home' encrypted LV.
Code:
--- Physical volume ---
PV Name /dev/sda1
VG Name Data
PV Size 74.56 GiB / not usable 2.00 MiB
Allocatable yes (but full)
PE Size 4.00 MiB
Total PE 19087
Free PE 0
Allocated PE 19087
PV UUID QOvRgJ-P7Kb-g6RI-OLpM-Wxfa-AGz5-AW3CyN
--- Physical volume ---
PV Name /dev/sdb1
VG Name Data
PV Size 76.33 GiB / not usable 2.00 MiB
Allocatable yes (but full)
PE Size 4.00 MiB
Total PE 19541
Free PE 0
Allocated PE 19541
PV UUID JjE1zY-u0dp-jz6T-VOic-c2UB-BO5O-BQA0wp
--- Physical volume ---
PV Name /dev/sdc1
VG Name Data
PV Size 74.53 GiB / not usable 2.00 MiB

PV UUID 5nynBe-Jini-SmVf-02MW-xeGf-HSf2-6v7T1T

PV Size 465.61 GiB / not usable 0

Documentation on this scenario is light. Most suggestions seem to be that it isn't possible and that it appears I am stuck either backing up and then repartitioning or just creating a separate LVM and mounting the extra space somewhere and encrypting it (as opposed to simply expanding my existing encrypted LVM to include the additional disks)
I hope I am not too confusing..
