During the upgrade to SES 7 the "upgrade.status" module is reported as being unavailable

This document (000020414) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Enterprise Storage 7

Situation

During the upgrade to SES 7 after running "zypper migration" on the admin node and then attempting to get the upgrade status as mentioned in the SES 7 online documentation, this fails with:

:~ # salt-run upgrade.status
'upgrade.status' is not available.

Resolution

Temporarily un-install the "ceph-salt" RPM and re-install "deepsea"

Cause

The admin node had the "patterns-ses-admin" RPM installed prior to running "zypper migration" resulting in "deepsea" being removed and "ceph-salt" being installed during the migration.

Additional Information

The "patterns-ses-admin" RPM should not be installed (and is not installed by default).

There is an updated version of this RPM in the SES 7 repositories, now however for "ceph-salt". Since "ceph-salt" can not be installed along with "deepsea", the resolver removes "deepsea" and instead installs "ceph-salt" due to the updated pattern. The removal of "deepsea" and the installation of "ceph-salt" should however only happen manually later during the upgrade procedure as described in the "Installing ceph-salt and applying the cluster configuration" section of the online documentation.

To temporarily remove "ceph-salt" and install "deepsea" take the following steps;

Download the deepsea RPM via SCC, from within SCC go to "Packages > SUSE Linux Enterprise Server > 15 SP1 > $architecture > Enter "deepsea" > select the latest version > Download.
Remove ceph-salt: "zypper rm ceph-salt"
Install deepsea from the downloaded RPM: "rpm -ivh deepsea"
Optional, sync salt modules to all minions: "salt '*' saltutil.sync_all"

Continue with the upgrade procedure, and then normally remove "deepsea" and again install "ceph-salt" when the appropriate stage of the upgrade procedure is reached.
