We have tried the same renaming in the dev environment which has multiple
server nodes impacted and contains some data (unlike the local grid I
tested this on which had a single server node containing no data). This
environment failed to restart after those changes.
We are still looking into it
Looking at the cache-SiteModelMetaData folder in the persistence folder for
a server node shows a "cache_data" file 6kb in size. No other cache folders
contain this file.
As an experiment I renamed this file to "cache_dataxxx". This appeared to
be sufficient to permit the grid to restart.
