Selfhosted

59698 readers

A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

  7. No low-effort posts. This is subjective and will largely be determined by the community member reports.

Operation:

  • sudo vgs: ubuntu-vg 1 1 0 wz--n- 462.69g 362.69g
  • df -T / : /dev/mapper/ubuntu--vg-ubuntu--lv ext4 102626232 24338224 73028744 25% /
  • sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv
  • sudo resize2fs /dev/ubuntu-vg/ubuntu-lv

Never did this before on an encrypted drive. Is this the proper procedure? Obviously a complete image back up is in order, however, are there any gotchas, caveats, pitfalls that I should be aware of before proceeding?

lv* commands are for LVM logical volumes. They're not related to LUKS. Unless your LVM "physical" volume is on a LUKS encrypted device, you aren't using LUKS. You'll need to make the LUKS encrypted PV larger before you can grow your LV.

Unless your PV is already taking up the whole disk, in which case whether it is LUKS encrypted or not is irrelevant and the question you want to be asking is "how do I resize my LVM LV to fill the rest of my LVM PV?", which is probably what the commands you have do.

Again, apologies for my confusion and not being able to articulate coherently or precisely.
