Answer 1

你可以试试这个，它对我有用：

sudo apt-get autoclean

Answer 2

Please try to use commands to resolve your issue:

root@****:~# lsblk

NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 0 150G 0 disk
└─xvda1 202:1 0 8G 0 part /

root@****:~# df -h

Filesystem      Size  Used Avail Use% Mounted on
/dev/xvda1      7.8G  4.5G  2.9G  61% /
tmpfs            32G     0   32G   0% /dev/shm

Looking at above thing it seems that EBS is having 150 GB but the root partition is only 8 GB.

So to resize EBS Root Volume

root@****:~# sudo growpart /dev/xvda 1

To install "growpart" use

root@****:~# sudo yum install -y cloud-init dracut-modules-growroot

And restart the engine.

Answer 3

I just encountered a similar issue.

Solved in two commands without a reboot:

It was due to the LV created by default on ubuntu installation. 1. Find the LV name with lvdisplay. 2. lvextend -rL +1G LVNAME (or instead of "-r" you can resizefs as the next command)

Answer 4

The answer given above by ECB worked for me but it required LV Path insted of LV Name in the second part of the answer.

An alternative suggested by a colleague will resize to use 100% of the disk.

sudo lvm
lvextend -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv
exit

sudo resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv

Answer 5

Try

sudo fsck.ext4 -f /dev/sda1 

(sda1 is the drive you linux is installed / is on) On a Live CD. I used gparted live( https://gparted.org/livecd.php ). This will repair the file systems nodes. File system is read-only because File system is broken.

Answer 6

Your root file system is full and hence your temp dir (/tmp, and /var/tmp for that matter) are also full. A lot of scripts and programs require some space for working files, even lock files. When /tmp is unwriteable bad things happen.

You need to work out how you've filled the filesystem up. Typically places this will happen is in /var/log (check that you're cycling the log files). Or /tmp may be full. There are many, many other ways that a disk can fill up, however.

du -hs /tmp /var/log

You may wish to re-partition to give /tmp it's own partition (that's the old school way of doing it, but if you have plenty of disk it's fine), or map it into memory (which will make it very fast but start to cause swapping issues if you overdo the temporary files).

Or try unmounting the overflow partition:

umount /tmp

OR

umount overflow
