Tom, Thanks for the help I was able to find pg_resetxlog in the path. Are there any precautions that I need to be aware of? Or I just don't have any choice? I'd like to do pg_dump or pg_dumpall. Should I do a pg_resetxlog $PGDATA? Here is my pgcontrol info: ------------------------------------------------------------------ _control version number: 71 Catalog version number: 200101061 Database state: SHUTDOWNING pg_control last modified: Tue Feb 2 08:19:14 2010 Current log file id: 2 Next log file segment: 249 Latest checkpoint location: 2/F8D581BC Prior checkpoint location: 2/F8D49A34 Latest checkpoint's REDO location: 2/F8D581BC Latest checkpoint's UNDO location: 0/0 Latest checkpoint's StartUpID: 210 Latest checkpoint's NextXID: 79276624 Latest checkpoint's NextOID: 4412280 Time of latest checkpoint: Tue Feb 2 06:50:48 2010 Database block size: 8192 Blocks per segment of large relation: 131072 LC_COLLATE: en_US LC_CTYPE: en_US --------------------------------------------------- In my pg_xlog directory, I've: total 32808 -rw------- 1 postgres postgres 16777216 Feb 2 06:54 00000002000000F8 -rw------- 1 postgres postgres 16777216 Feb 1 10:51 00000002000000F9 ------------------------------------------------ Thanks for any help.

My Postgresql has this error "FATAL 2: XLogFlush: request is not satisfied". I tried to follow the instructions from a thread about looking for a core dump, but when I tried to start the postmaster, I got "/usr/bin/postmaster: Startup proc 30595 exited with status 512 - abort". You've got a corrupted page that is affected by a WAL replay operation, so things are pretty much a mess. > I'm pg version is postgresql-7.1.3-2. What are my options? [ blanches... ] You do realize that that version has been obsolete since 2002? pg_resetxlog was a contrib module in 7.1, so if you can find the software repository you got postgresql from, you should be able to install postgresql-contrib. However, I am betting this thing is so old that you don't even have the chance at doing that. Most likely you're going to have to go back to your last backup. After which, you should make it a priority to get onto a less antique version of Postgres (and the underlying OS too, no doubt). regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
