 ext3 with data=ordered Is it reasonable to mount the PGDATA filesystem with data=writeback on ext3 as long as the PGXLOG filesystem is mounted data=ordered and fsync=on? Or is this only acceptable if you have battery backed controllers? -- Jeff Frost, Owner <jeff@frostconsultingllc.com> Frost Consulting, LLC http://www.frostconsultingllc.com/ Phone: 650-780-7908 FAX: 650-649-1954 ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org      |

Or is > this only acceptable if you have battery backed controllers? data=writeback is fine on all PostgreSQL file systems, including pg_xlog because we fsync() it on commit. In fact it is the recommended mount option for ext3. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073 ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to majordomo@postgresql.org so that your message can get through to the mailing list cleanly |
