This usually means the root partition is full or Docker is not using Zfs or the zpool is full.
First ssh to the antsle's command line?
or
ssh root@x.x.x.x
or if on Windows use Putty
We can check if the root '/' partition is full with
df -h /
If it is full, we can check for large files with
for file in `find / -xdev -type f -size +200M` ; do ls -lh $file | awk '{printf "%s\t%s\n", $5, $9;}' ; done
If it is safe to remove the file, use the following command
rm /path/to/file
To check the zpools run
zpool list
The CAP column show the percent full and the FREE column the free space.
If the antlets zpool is full or nearly full, I would first try to remove any unused templates. An unused
template is a template from which no antlet has been created.
You can see the list of templates with
ll /antlets/_templates
To remove a template use
zfs destroy -r antlets/_templates/TEMPLATENAME
Note, there is no leading '/' in the path.
This will error if an existing antlet is dependent on the template.
If you get a 'data set is busy' error, then remove the directory first then run the zfs destroy again.
example:
rm -rf /antlets/_templates/Win2016
zfs destroy -r antlets/_templates/Win2016
If there are any antlets you can delete, lets remove those. Here is a guide on removing antlets from the command line:
