Since I installed Mint 19 in March, I have been getting this message on screen very frequently. Cinnamon version 3.8.9, Linux Kernel 4.15.0-65-generic, Memory 7.7GB and Hard Disk 1735GB.

The volume local has ( - ) space The space varies every time.

Last couple of weeks the computer restarts automatically and when the desktop mint screen comes on a similar message appears before i even touch the keyboard.

Not sure if both are related issues.

The volume local is mounted as /usr/local and it has 55GB allocated space now.

I tried to increase the space using Gparted but it did not allow me to increase more than 5GB.

Any thoughts! Thank you

do you mean there is no free space on that volume? Or: what do you want to solve?

Why am I getting that message?

The amount of space available varies each time. Sometimes 0 MB available sometimes 4.4 MB and other times something like 658 MB. Is that causing an issue. It also gives the option to "Examine" or "Ignore". If I try to examine it shows all the files it is storing in there but will not allow me to delete them. It has a directory called "Timeshift" Inside that other directories; such as "snapshots", "snapshots-boot", "snapshots-daily" and similar directories and files.

Yes, that is a disk full message. At least it is almost full. You can examine the content and make some free space or ignore the message.
But I have no any idea what can be deleted.

But it wont let me delete?

Can I increase the space?

Depending on how Timeshift is configured it can create multiple snapshots of your entire system. If logs and files etc are created and deleted it will be reflected in the size of the snapshot and used space. I think the default settings keeps the last 5 snapshots. Depending on your backup needs you can reduce the number of snapshots that are kept which will keep the filesystem from becoming full. I also think timeshift will not create a snapshot if there is insufficient space on the volume. Assuming local is an ext filesystem you can reduce the amount of reserved space ( 2.75 GB ) which will give a little extra wiggle room without needing to resize existing volumes using the tune2fs command.

The output of the following commands should show how the drive is partitioned and hopefully if there is any available space.

sudo parted /dev/sdx print (where x is the drive letter of your hard drive if unknown see output of above command)

Sorry for the delay in responding, I was away.

Out put for
Output for sudo parted /dev/sdx print

I forgot to ask for the output of the df -h command.

The posted information shows the disk as 500GB versus 1735GB (sdb?) and the only partition that is 55GB is sda1. Without seeing how much space is used on the other partitions we can not say what partition you can "steal" space from however I don't know why you need 52GB of swap space. Moving space around always has a bit of risk so be sure to save backups to another drive.

As stated decreasing the number of saved backups should provide more space without having to resize anything at the moment.

And the output for sudo parted /dev/sdb print
I didn't know how much to allocate for SWAP so I gave it 55GB, what would be more than enough? Could I decrease the number of backups through GUI or do I have to use commandlines? Thank you

Yes, you can configure the number of retained backups from the time shift GUI.

The amount of RAM depends on how you use your system and if you hibernate. With 7.7 GB RAM you could get by with zero but by default I usually use 1X RAM.

It looks like sda1 and sda3 are physically next to each other on the disk. You can shrink /usr and move it to the right, then expand your /usr/local. Lets see what happens first when you reduce the number of retained backups. You could move the location of your backups to another folder too.

Is it possible to limit the sort of things that Timeshift includes when it works? If so, I would prohibit it from including any directories that are used for caches, image thumbnails, etc. If you do a lot of internet browsing there can be a huge number of those objects---and the total size of them can be considerable. IMHO, it's a waste of time to be making backup copies of those things. Unfortunately, because there's no standard on where they might be located in one's directory tree, it can be an iterative process finding which directories are used for them so you can filter them out.

Yes, you can include/exclude directories/files from a backup using the GUI configuration tool.

Sudharshans,

Your Timeshift snapshots should be saved to your much larger home directory (/dev/sdb1) or elsewhere with sufficient capacity. The root directory (/dev/sda1) is almost full as you have found out.

To delete all existing snapshots in sda1, open Timeshift, select all snapshots from the list (CTRL+A) and click the Delete button at the top.
Then in Timeshift, select Settings > Location and change this from sda1 to sdb1.

Thank you and I reduced the number of snapshots from 5 to 1 yesterday. So far I have not had the message that there is no space yet. Or that's what I thought. When I looked in It said snapshots disabled. And also there were no snapshots. So I have reset it again. Will come back tomorrow with the results.

Sudharshans,

You have not said whether you have deleted the Timeshift snapshots in sda1, which is virtually full.

Where are you saving the latest snapshots?
