File Systems and Workspaces
File system quota exceeded
There are quota limits for:
- disk space
- number of inodes (files)
Identifiy the issue:
- Disk space: List all directories (and files) in your home directory or workspace sorted by size. (.[!.]* makes sure the "hidden" dot files are also checked.)
du -sh .[!.]* * | sort -h | tail # or du -sh --apparent-size * .[^.]*
- Descend in a directory with a large reported size and repeat until you find large files that are worth taking care of.
- Number of inodes:
# check current directory ls -1a | wc -l # check subdirectories du -s --inodes .[!.]* * | sort -n
To free up space, you can:
- ...delete temporary files, for example in the
.cachefolder. Other folders starting with a dot might contain temporary files as well, for example.local/share/Trash. - ...use the cleaning commands by your used software (e.g. conda).
- ...delete folders with temporary data created by your used software (e.g. nextflow).
