1TB Nvme Drive Reports Almost Full Usage, Disk Usage Analyzer only shows 334.3GB Used

bamu · 5 November 2021 21:47

Thoughts on a Samsung 970 EVO 1TB drive reaching storage limit prematurely?

I’ve used lsblk below and the disk usuage analyzer tool to compare scans of the drive.

Any thoughts to what might be unreported by either tool?

Timeshift?

cscs · 5 November 2021 21:59

I also believe some sort of backups.

But as an aside … your SNAP situation is bloated. At least clean out the old/redundant versions

winnie · 5 November 2021 22:07

To rule it out,

sudo du -hs /timeshift

bamu · 6 November 2021 02:28

Thanks for the quick reply Winnie, here’s the output of timeshift.

[bamu@bamu-omen ~]$ sudo du -hs /timeshift
du: cannot access '/timeshift': No such file or directory

You need the full path to timeshift backups.

Thanks for the push, I’ve removed the duplicates.

Thanks for the response Robin,

I’m not certain where timeshift should be (or that I ever set it up).

I’ve tried grepping in /etc/ and /run/ after some Googling to find a likely location but nothings come up.

[bamu@bamu-omen etc]$ sudo grep -nr timeshift .
[bamu@bamu-omen etc]$ cd /run
[bamu@bamu-omen run]$ sudo grep -nr timeshift .
grep: ./docker/netns/9fc26b913f23: Invalid argument
grep: ./snapd/ns/indicator-sensors.mnt: Invalid argument
grep: ./snapd/ns/auto-cpufreq.mnt: Invalid argument
[bamu@bamu-omen run]$ cd ..
[bamu@bamu-omen /]$ ls

[bamu@bamu-omen boot]$ sudo grep -nr timeshift .

bamu · 6 November 2021 04:09

I think the culprit is docker and my mismanagement of it.

I ran the docker prune command and got back 256GB.

[bamu@bamu-omen lib]$ docker image prune
Total reclaimed space: 251.1GB

bamu · 8 November 2021 13:35

Docker was the culprit here, pruning and removing old images gave back 600+ GB of usable storage.
