[ClusterLabs] Antw: [EXT] Colocation per site ?

[Strahil Nikolov]

Disregard the previous one... it needs 'pcs constraint colocation add' to work.

pcs constraint colocation bkp2 with Master rsc_SAPHana_<SID>_HDB<inst. number> score=INFINITY node-attribute=hana_<sid>_site (or using any other attribute) brings 'pcs constraint help' output.
It seems that it doesn't like the syntax.
Maybe someone can share the 'pcs cluster edit' xml section, so I can try to push it directly into the cib ?

Oh! Thank you!

Indeed, this is exactly what OP needs. No custom scripting is needed.

Thank you for your patience.
