i run ubuntu server 22.04 LTS on a SSD 150GB. This SSD is suddenly filled up to 100%. I deleted some logs and files I was sure not to need anylonger. But this gives me only 8% more space.

I read a lot of the similar posts, but it can not be to increase the partition. I searched the big files. The server lists about ten items then does nothing . I only can cancel the search after 10 Minutes.

I checked the kernel.img and coredumps an deleted that mostly. This resulted in a 8% gain.

Do I realy have to reinstall the server?

    Does this answer your question? What do I do when my root filesystem is full? – Artur Meinild May 29 '23 at 11:54

    Had a bit of unusual case. Setting up full install to external SSD. I used rsync to copy a lot of data in data folders. And link data into /home. Somehow I managed to copy data into the mount point (before link?), so system did not show data but said partition was full. Only by viewing mount points and seeing data that should not be there from my other install could I tell I copied data to wrong place. – oldfred May 29 '23 at 13:47
  • Thank you for your comments and links. These I have already studied and tried out. I will try to find out if I can view the mount points and consider if something is in the wrong place - so far I have no indication for that. – Manfred Kupper May 29 '23 at 14:46
  • Please update your question with the output of the following commands: lsblk and df -h – mpboden May 29 '23 at 15:41
  • And also sudo du -hx / | sort -rh | head which will show the biggest folders in your root filesystem. – Tilman May 29 '23 at 17:03
  • It looks like your Nextcloud data is mounted to sdb2. I’m guessing your intention is to have it on your raid device. I’m not that familiar with Nextcloud, but I would think it needs reconfiguration and the data moved. – mpboden May 29 '23 at 17:52
  • Thanks a lot. This seems to be the case, after you provided me with lsblk. I was offline. But now I will try to fix the nextcloud configuration. – Manfred Kupper Jun 01 '23 at 15:04
