#690 Opensaf start failed when RDE could not RESPAWN.

[manu]

Changeset:- 4733
Opensaf is up and running.

1)Set the SCED_BATCH for thread priority in nid.conf

export OSAF_MDS_SCHED_PRIORITY=5
export OSAF_MDS_SCHED_POLICY=3

2) Restart the opensaf on the node. And scheduling policy (for MDS) sets to its default value (Priority 85 and Policy 2)

Dec 24 14:37:37 SLES_NEW2 osafckptnd[14637]: scheduling priority 85 for given policy 2 to the task OSAF_TMR
Dec 24 14:37:37 SLES_NEW2 osafckptnd[14637]: scheduling priority 5 for given policy 3 to the task OSAF_MDS is not within the range, setting to default values
Dec 24 14:37:37 SLES_NEW2 osafckptnd[14637]: scheduling priority 85 for given policy 2 to the task OSAF_MDS
Dec 24 14:37:37 SLES_NEW2 osafamfwd[14652]: Started

3) Again Reset SCED_BATCH for thread priority in nid.conf

export OSAF_MDS_SCHED_PRIORITY=0
export OSAF_MDS_SCHED_POLICY=3

4) Restart the opensaf on the node. Now opensaf is not coming up. And default value is also not reflecting (for MDS).

[Anders Widell]

Here you are trying to set the scheduling policy to 3 (SCHED_BATCH), which is not a valid scheduling policy for threads. We can add a check that falls back to the default policy whenever an invalid policy is encountered.
