I can not comment on moving restorePbe to commit for now. But a SMF rollback is
what is used to undo the campaign operations. A reboot would only clear changed
IMM data if PBE was off. That leaves software and CLI operations, which would
cause incompatibilities.
A rollback has to be planned for in a campaign and does not handle errors. So
by default SMF takes a backup before starting a campaign to be able to recover.

** [tickets:#2648] smf: smfd crashes after cluster reboot when campaign is in
ExecutionCompleted**
**Status:** review
**Milestone:** 5.17.10
**Created:** Thu Oct 19, 2017 06:45 PM UTC by Alex Jones
**Last Updated:** Thu Oct 19, 2017 07:21 PM UTC
**Owner:** Alex Jones
smfd crashes in updateImmAttr because it returns NO_RESOURCES. Here is how to
reproduce:
1. enable PBE, and make sure the "disable" flag is set in OpenSafSmfConfig
2. execute an upgrade campaign, and let it go to "execution completed", but
don't commit it
3. reboot the entire cluster
4. only allow 1 system controller to come up
5. smfd will attempt to re-execute the campaign
6. any writes to IMM (like setting an error because the campaign file can't be
found) will fail with NO_RESOURCES and smfd will assert and crash
The reason for the assert and crash is because PBE has not been turned off by
smfd before the campaign has been inititialized.
