Description

Steps to retest:
1. Have a satellite spin up to work on
2. Spin up a rhel box for the NFS share
3. On both systems, run: "rpm -q nfs-utils"
a. This checks if the system has nfs already installed (it should)
4. On NFS share, run "systemctl status nfs-server" to check if NFS is running or enabled
5. If not, then enabled the it via "systemctl enable nfs-server --now" and recheck status. It should be active.
6. run: “systemctl start nfs-server”, then “systemctl status nfs-server” to ensure that running NFS-server is running.
7. Ensure that the dir /mnt is blank because we're using this location for the export but you can put it anywhere or create a separate dir for this
8. Create an export point by adding "/mnt <sat-server>(rw)" to /etc/exports using vim
9. Stop firewall just in case: systemctl stop firewalld
10. Run: exportfs -r
11. set permission to write into /mnt with chmod 777 /mnt
12. On the satellite, create a separate folder (pulp1)
13. Grant all permission to pulp1 and /var/lib/pulp/ by running: chown -R pulp:pulp /var/lib/pulp/ and chown -R pulp:pulp pulp1
14. run: mount -t nfs <nfs-share server name>:/mnt pulp1 -v
a. It should output something like this for status:
mount.nfs: timeout set for Fri Mar 18 14:25:52 2022
mount.nfs: trying text-based options
15. copy everything in /var/lib/pulp to the share: cp -r /var/lib/pulp/* pulp1
16. On NFS, check /mnt to ensure that the folder structure of /var/lib/pulp is in there (it should have assets, import, exports, tmp, etc)
17. Check the uid an gid of sat: grep pulp /etc/passwd
18. On NFS, create group, pulp user, and grant necessary permissions: groupadd -g <gid> pulp, adduser -g pulp -u <uid> pulp, chown -R pulp:pulp /mnt
19. Ensure that the uid and gid matches between NFS share and sat: grep pulp /etc/passwd
20. run: umount <NFS share hostname>:/mnt
21. Remount the NFS share to /var/lib/pulp/ with: mount -t nfs <nfs-share server name>:/mnt /var/lib/pulp/ -v
a. Steps 14-18 is necessary so the NFS share has the same file structure as /var/lib/pulp in the export in /mnt. Then we can mount to /var/lib/pulp/ so that any writing into that dir in satellite can
be directed to the NFS share one. If we don't do this, and we mount directly to /var/lib/pulp/, then pulp cannot work if all its contents was removed by mounting the empty filesystem
22. run: restorecon -Rv /var/lib/pulp
23. Restart pulp services or all services on satellite: foreman-maintain service restart
24. run: showmount -e <NSF share hostname> to ensure mount is still active
25. Create a custom repo and sync
26. Create a cv, add the repos, and publish
Expected result:
step 25 and 26 should complete successfully
Actual:
Step 25 and 26 does complete successfully
To ensure that NFS share does populate correctly, I checked /mnt/media/artifact and the folder was populated. Prior, the artifact folder wasn't created because I haven't synced any repos yet. After syncing, content should appear in "artifact", which it did in my case.
Verified on 6.11 snap 14 with tfm-pulpcore-python3-pulp-rpm-3.17.3-2.el7pc.noarch on rhel7.9 and rhel8.5
