I have some partitions out of size. Can I make room for them?

$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            476M     0  476M   0% /dev
tmpfs            98M  808K   98M   1% /run
/dev/xvda1       15G  7.5G  7.1G  52% /
tmpfs           490M     0  490M   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           490M     0  490M   0% /sys/fs/cgroup
tmpfs           490M  8.0K  490M   1% /tmp
/dev/loop2       34M   34M     0 100% /snap/agent/3552
/dev/loop1       56M   56M     0 100% /snap/core18/1006
/dev/loop0       56M   56M     0 100% /snap/core18/2074

I tried this one but it didn't work

vresize -L+100M /dev/loop0 /dev/xvda1:0-1 /dev/xvda1:0-1

"/dev/loop0": Invalid path for Logical Volume.

  • If you used lvresize (not vresize) then that would be for a LVM system. You don't have Logical Volumes etc. Jun 25, 2021 at 22:35
  • Add the output of fdisk -l | grep xvda as root to your question. Jun 25, 2021 at 23:19
  • How can increase the size of /dev/loop2 then? @JeremyBoden

  • Do you have any errors saying that you have insufficient storage/memory for any processes? Jun 26, 2021 at 11:50
  • Yes I do. I use OSSEC and receive lots of emails with the alert Level 7 - Partition usage reached 100% (disk space monitor). That's how I found this. I'm just looking a way to fix this issue. @JeremyBoden

1 Answer 1


The loop devices used by snap packages are supposed to be using 100 % of the space, that's normal. Snaps are squashfs images that are mounted using loop devices, they don't need extra space and you can't resize them.

  • Thank you for the information. I receive lots of alerts from OSSEC — Level 7 - Partition usage reached 100% (disk space monitor). In this case, how can I fix this problem?

  • Use less disk storage. Do you have extra storage not shown in the question? Jun 27, 2021 at 9:28
  • I'm not familiar with OSSEC, I found this issue on their github, there are some suggestions for workarounds/custom rules there. If this doesn't work, I'd recommend asking a new question about this. Jun 27, 2021 at 9:43
  • @VojtechTrefny thanks for sharing that suggestion. It didn't work on my end. I just asked it as a new question.
