[ClusterLabs] Antw: Re: SLES11SP4 (crmsh-2.1.2+git49.g2e3fa0e-1.32): problems parsing nodes

[Ulrich Windl]

Hi!

An update:
The fix was to delete the nodes and re-create them. CRM shell was happy then,
displaying the node like this:
---
node h04 \
        utilization utl_cpu=200 utl_ram=1200 attributes standby=off
---

But when committing the config I got warnings in syslog like this:
pengine[25263]:    error: crm_int_helper: Characters left over after parsing
'off': 'off'

I feel different parts of the cluster stack have different expectations on the
syntax...

Regards,
Ulrich
