Hello, Is it safe, to have RAID controller (not BBC) write cache _enabled_ for disks where data are stored and write cache _disabled_ for disks where WAL segments are stored? I _can_ afford of loosing some data in case of power failure. But I'm afraid of having database in unrecoverable state after crash.
fsync = on I have 4 disks, 2 for WAL (RAID1) and 2 for data (RAID1). WAL and data are on XFS partitions (nobarrier, noatime). -- Piotr Gasidło -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
