Deleting an OSD in Rook
View rook_osd_zap.txt
Lets assume you want to get rid of OSD.2, and none of the "nice" ways worked.
- Determine the node where the OSD daemon is running (`kubectl -n rook-ceph get pods -o wide|grep osd.2`)
- Enter the toolbox pod, run `ceph osd out 2`
- Wait for the cluster to migrate the data away (`ceph status -w`)
- Delete the Rook deployment for OSD 2.
- Enter the toolbox pod, run:
- ceph osd crush remove osd.2
- ceph auth del osd.2
- ceph osd rm 2

Find hacked mail account used for spam sending (Postfix)
View checkqueue.py
'''
This script checks the current Postfix mail queue for mails that
where delivered through SMTP authentication. It then shows both
the authentication user name and the sender mail adress.
Since spammers normally don't use a valid sender adress in your
administrative domain, you quickly see the problem.
Run with "python3 checkqueue.py"
