I’m betting the root of this problem is on how I originally installed the system but I would like another opinion. Or several.
Running Mint.
After analyzing the disk usage, the folder where Thunderbird is installed is completely full. I have four separate accounts in it but a single one is responsible for taking all the space available, through the imap/sent folder, which makes no sense for me, as I send relatively few messages compared with all the messages I receive.
I already considered just purging the program from my system and completely reinstall it but if I’m going to do that I’m better off doing a fresh system installation.
The system has two disks: a SSD running the system core and a HDD for the home partition. I opted to keep the system core on the SSD to speed up booting (and it worked) and used the HDD for storage because. I prefer HDDs for user files, for longevity reasons. The biggest mistake I made here was not using LVM on the disks.
Any thoughts and criticism on this is welcome.
Thank you in advance.
Check inodes
df -ih.

Maybe I’m reading this wrong but doesn’t that show that you only have a 30 megabytes of space?
df -h returns this

Looks fine to me as well, so you are using ext4 and not btrfs?
Yes. Still haven’t tried it.
I wouldn’t bother with a HDD in the future. They are slow and SSDs will last for years.
Anyways, could you post the output ofNever mind, I missed your commentdf? It would help significantly with troubleshootingWith the memory chips getting the sharp uptick they are going through right now? Pass. Speed is not crucial for me. I don’t do any hardcore gaming nor run some speed critical apps. HDD’s cover my necessities.
You haven’t mentioned your distro. Are you using systemd-homed? There are some footguns there that can manifest like this.
As another poster mentioned, btrfs quotas or subvolume allocation could be a favtor as well.
I always leave something to be said when I post… added to the post. Thank you.
I’m running Mint.
Yes. Although recently I started getting errors with downloads, with warning of not having disk space.
I’m a bit confused. What is the actual problem? You’re getting an error in Thunderbird?
Are you able to use your home partition normally outside of Thunderbird?
Thunderbird works. But I’m getting error messages about not having disk space available. When trying go make downloads, I get an error message from the browser. Using the disk analyzer in Mint, I can see the folder for Thunderbird and in there the ubfolder for the IMAP sent messages is full.
Folders don’t get “full”—partitions do. Do you perhaps have a limit imposed inside Thunderbird’s settings on how much disk space it can use up? Do you get any errors about disk usage outside of Thunderbird?
I didn’t set a separate partition for mail. Thunderbird is in the general /home. But it appears to have reached a size of 6.1GB under imap/sent and that area is flagged as being out of space.
The email ocasionallly returns an error message of not having disk space available for new messages.
But when trying to make downloads to /home/downloads several have been aborted due to not having available space.
This makes no sense. With nearly 400GB of /home free, every user /home folder should just slowly fill that space as required/needed. But that is not what is happening. The free storage space is not being accessed
Can you do more testing with other applications trying to write to
/home? Are you sure it’s not a Thunderbird bug/misconfiguration?If it happens for other programs trying to write to
/homethen I’m stumped ngl. I assume you have checked for hidden files.I risk it is. It makes no sense why the space for the mail client is getting full while the rest of the disk is nearly empty.
LibreOffice saves with no problem to the disk. The browser saves small files with no issue. Dowloading large files, on the other hand, returns a error of no available storage space.
I’m just backing up all the files and reinstalling the system.
What is the output of
df -h? It’s hard to guess what could be wrong without some more data.The last 5% are by default reserved for the root user, so that’s a possibility.

Yeah, those aren’t full from a filesystem perspective. What exactly are you doing when it’s saying it’s full, and what is the exact message. Some things might have quotas independent of the space on the filesystem.
I got my first warning when trying to download some large files and at some point the browser just returned a message saying the download was aborted for not having enough space available. Nothing else.
After running a disk scan, as I know the 500GB HDD is essentially empty, is when I find out the Thunderbird folder is full. And somehow it is causing the system to flag the entire disk has full.
This is the general use computer of the house and there are more users on the system but I have the largest amount of files on it as I’m the primary user.
What is “a disk scan”? Can you either copy the input/output of the command or take screenshots? This is too vague to be of much use for debugging.
df -h returns the following

Did you check dmesg for errors? It might be smart to verify it isn’t a hardware issue.
Could you post screenshots?
the dmesg output is simply huge running the command threw me a slew of messages can you point to what I should be looking at?
Do you see any red ones?
No reds
