Patchlevel differ between master and new installed member

Error message in log or on screen:

ERROR : cannot join pool [The hosts in this pool are not homogeneous. reason: Updates on local host xenmaster1 and pool host xenmember2 differ] - abort

If you want to install a new member server in an existing pool and your pool update list file look like:

!XS82ECU1005.iso
!XS82ECU1009.iso
!XS82ECU1012.iso
!pvsaccelerator.iso=1.0.9

but your master has installed more updates

the pool join will failed.

Some fixes contain older version of the same fix part but if you install updates not with fsi but XenCenter you have to change the pool.upd file manually.

Add missing updates to pool.upd file:

• on command line with an editor in folder /opt/fsi/inst/<xen source tree>/ks/pool/<pool name>/ the file pool.upd or
• in fsi portal - pool detail view and in tab “Update”

• update.lst information
