I do not run my databases on LVM because, at least in the past, LVM did not properly honor fsync / write barrier commands. I don't know if this has since been fixed. If your transaction rate on LVM is unnaturally higher than it should / could be, then suspect it is not fsyncing, and putting your data on it is putting it at risk. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
