can't update

How big is the /boot partition? You can get that from SSH by doing the following:

cd /boot
df -h .

The only things that are in the /boot partition are the parts of the kernel needed to boot. If it's filling up, then the only thing you can really do is to tell yum/dnf/apt to save less kernel versions. From memory CentOS based systems will save 5 kernels.

Filesystem Size Used Avail Use% Mounted on
/dev/md1 487M 424M 39M 92% /boot


It is almost full
How can i adjust ?

I found this too :



The filesystem “/” mounted at “/” reached “warn” status because you currently use 87.1% of its available blocks.



Used:357.83 GB Available:56.27 GB Total:436.34 GB

Is it related to files saved on the drive or it could be something else ?!

The only thing you can do to free up space in /boot is to remove kernels. You can figure out how may you have by simply listing the files and counting the number of vmlinuz* files there. A 487 MB boot partition is really small. In /etc/yum.conf you can set "installonly_limit=#" (where # is a number) and that will limit you to only # kernels and any more than that will be removed when a new one is installed. You need at least 2, so you can go back to an older kernel if you have issues. You can also use "package-cleanup --oldkernels --count=#" to manually reduce the number of kernels to #. You'll want to search/read up on "limit number of kernels CentOS" or something like that to get more details etc.

The root partition ("/") is where everything else is stored. The rest of the OS, all your sites/email, MySQL is stored there. Unless you have very large error_log files the only way to clean up space to to reduce the account usage.

You basically have a very small system.

There is only 11 vmlinuz , which one should i remove ?

* About "installonly_limit=#" , currently it is set to 5 , is it enough ?!

* Also "package-cleanup --oldkernels --count=#" , should it be set to 5 in my case or it doesn't matter to the previous number of ( installonly_limit ) .

* The root partition , it is almost 500 GB of size , i think it could be the Backup files which is taking more space , what command can alow me view the large files / folders ?

You currently have 5 kernels installed (I don't believe the rescue kernel counts):

You don't want to just remove files, you either need to run the package-cleanup or change the installonly_limit and then yum will clean up properly.

If you are backing up to your root partition, that will eat up a lot of your space. How much depends on how you are backing up (compressed, incremental etc.) and how much you are retaining. You may want to look at off server backup storage.

As i mentioned , installonly_limit already set to 5 ,

so what do you think ?

The backup is on " Compressed " , it is set to daily and monthly .
But my question about this , is there a way to delete old backups , lets say if it is older than a month , the system delete it automatically.
