I've seen it written a couple of times in this thread, and in the wikipedia article, that SOME sw raid configs don't support write barriers. This implies that some do. Which ones do and which ones don't? Does anybody have a list of them?
I was mainly wondering if sw RAID0 on top of hw RAID1 would be safe. -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
