Recently I found
/run/shm folders to be missing.
I tried to recover some files with a mounted disk, I now know that this may caused the harm. So unaware what to do, I created these directories by myself.
Now I looked up the command
df -h and saw this output:
Filesystem Size Used Avail Use% Mounted on /dev/sda6 913G 69G 798G 8% / udev 5,9G 4,0K 5,9G 1% /dev tmpfs 2,4G 872K 2,4G 1% /run none 5,0M 0 5,0M 0% /run/lock none 5,9G 2,1M 5,9G 1% /run/shm /dev/sda1 915M 358M 509M 42% /boot
I didn't know there were such file systems, how can I mount them in again? Is this something harmful?
I also saw that I have high I/O with my Journal
jbd2/sda6-8 always around 40%, has this something to do with this?
