That would work. As long as it is possible to rollback the campaign it 
is fine.

** [tickets:#2648] smf: smfd crashes after cluster reboot when campaign is in 
ExecutionCompleted**

**Status:** review
**Milestone:** 5.17.10

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.

[tickets] [opensaf:tickets] Re: #2648 smf: smfd crashes after cluster reboot when campaign is in ExecutionCompleted

2017-10-19 Thread Rafael Odzakow via Opensaf-tickets 
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.
