I’d like to use my Rock64 as a file repository by attaching an external SSD to the USB3 interface.
And, for a couple of different reasons, I would like to allocate space on the external SSD using the Linux Volume Manager [LVM].
- Is LVM supported by DietPi?
- What are the recommendations for using LVM on DietPi?
I only ask because I noticed that LVM doesn’t seem to be an option that’s available in dietpi-software or dietpi-drive_manager. But it is available via APT.
FWIW: Installation was a breeze…
dietpi@DietPi:~$ sudo apt install thin-provisioning-tools lvm2

Need to get 2,090 kB of archives.
After this operation, 8,324 kB of additional disk space will be used.
Do you want to continue? [Y/n]
And LVM seems to work as it usually does…
dietpi@DietPi:~$ sudo pvcreate /dev/sda1

In conclusion: It seems to “work right out of the box”! I’ll put it through a few paces and report back!
I did a LVM test installation in the past. Some information on this post https://dietpi.com/forum/t/2nd-usb-drive/4582/2
