From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

very small system partition with LVM on debian. Is it OK? (lemmy.ca)

I recently installed debian 12 using debian-12.2.0-arm64-netinst.iso. It is the only OS installed and I used the whole 500GB disk.

I selected something like guided partitioning with separate /home/ using LVM and encryption. Now that I am using my system a bit, I realize that I don't think it ever asked me how big to make the / partition and it is very small. Only 27GB.

Will this be a problem?

Or, is the LVM going to allow the partition to be resized or otherwise take up as much of the space as it requires?

# lsblk
NAME                    MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINTS
sda                       8:0    0 476.9G  0 disk

├─sda2                    8:2    0   488M  0 part  /boot
└─sda3                    8:3    0   476G  0 part  
  └─sda3_crypt          253:0    0 475.9G  0 crypt 
    ├─mycomputer--vg-root     253:1    0  27.9G  0 lvm   /
    ├─mycomputer--vg-swap_1   253:2    0   976M  0 lvm   [SWAP]
    └─mycomputer--vg-home     253:3    0   447G  0 lvm   /home

I tried booting into a live usb to resize the partition using gparted but I couldn't seem to do so.

If I need to reinstall and change something I'd rather do it now than later.

It's fine. "Only 27GB" is hardly too small for the system, even a bloated system wouldn't take that much space.

But if you must have a larger partition I think a reinstall would be easier, resize the partition is possible but because of the encryption not a straight forward thing. I wouldn't bother really.

If LVM isn't somehow mitigating the issue I will do a reinstall.

I have run out of space on / before and it is a huge pain in the ass. I do not need much room for /home on this system so I would prefer to be cautious and avoid problems down the road.

Hopefully I will be able to figure out how to specify this.... maybe a different installer image.

It's two commands to grow the / fs on the fly:

lvextend -L+10G /dev/mycomputer-vg/root
resize2fs /dev/mycomputer-vg/root

So don't worry about it. LVM is great :).

The installer lets you do a custom partition layout.

That is my previous experience. I guess i missed it somehow.
