Now I'm sure that the following configuration can destroy a PostgreSQL
8.3.5 database:
* Linux host with XEN, XFS filesystem with "nobarrier", RAID controller
with battery backed cache.
* XEN vm with XFS filesystem with "nobarrier" with postgresql
* your daughter with 3.5 years switching off the power supply of the
server
I guess one shouldn't use "nobarrier" on a XEN XFS domU machine.
Would that help? I'd like to enter this in the FAQ, as people (including
me) will be very upset to loose data, or destroy databases.
