see: https://docs.saltstack.com/en/latest/topics/jobs/job_cache.html

Stop salt-master service:

systemctl stop salt-master

vi /etc/salt/master

job_cache: False

Verify config file with out # lines:

cat /etc/salt/master | grep -E "^[^#]"

How to clear salt-master cache:

rm -rfv /var/cache/salt/master/jobs/*

Note: It can take some time to delete the cache, so monitor with:

watch "ls -al /var/cache/salt/master/jobs/ | wc -l"

or count # of sub-directories & Jobs:

find /var/cache/salt/master/jobs/ -name "*" | wc -l

When done, start salt-master service:

systemctl start salt-master

How to change ownership of files/directories to salt:salt:

chown -R salt:salt /var/cache/salt/master/jobs/*

find /var/cache/salt/master/jobs -group root -name "*"
