How big are WPARs because they might cause problems & fill up rootvg – depends on how much stuff you put in the WPAR file system?
This is something to watch out for but that is normal AIX system administration. Note: in the current release, a WPAR can’t access a volume group – only the file systems. So I guess your question applies to file systems filling up. By default, each WPAR gets its own root part file systems anyway, so one WPAR filling its file systems won’t affect any other WPARs. The maximum amount of disk space a WPAR can consume is therefore limited to the size of those file systems. If you are concerned about filling up rootvg, you can specify an alternative volume group using “-g othervg” to mkwpar.
