Hi, This is my first post to this list, so I hope I am posting it to the correct lists. But I am really stuck and getting pretty desperate at the moment. This weekend my database crashed while importing some Openstreetmapdata and I can't get it back to work again. It happened before and normally I would reset the WAL-dir with the pg_resetxlog command. I would loose some data but that would be all. This time it is somehow different because he doesn't recognize any of the important files anymore. For example when I try to start Postgresql again with the command: /usr/lib/postgresql/9.1/bin/pg_ctl -D OSM/ start
I get the following error: FATAL: could not create lock file "postmaster.pid": No such file or directory But when I do a ls -l on the directory I can see the file exists. drwx------ 0 postgres postgres 0 Jan 24 10:07 backup drwx------ 0 postgres postgres 0 Feb 14 11:10 base drwx------ 0 postgres postgres 0 Feb 17 09:46 global drwx------ 0 postgres postgres 0 Oct 11 10:49 pg_clog -rwxr-xr-x 0 postgres postgres 4476 Oct 11 10:49 pg_hba.conf -rwxr-xr-x 0 postgres postgres 1636 Oct 11 10:49 pg_ident.conf drwx------ 0 postgres postgres 0 Feb 17 11:29 pg_log drwx------ 0 postgres postgres 0 Oct 11 10:49 pg_multixact drwx------ 0 postgres postgres 0 Feb 17 08:58 pg_notify drwx------ 0 postgres postgres 0 Oct 11 10:49 pg_serial drwx------ 0 postgres postgres 0 Feb 12 09:58 pg_stat_tmp drwx------ 0 postgres postgres 0 Feb 14 09:01 pg_subtrans drwx------ 0 postgres postgres 0 Oct 11 10:49 pg_tblspc drwx------ 0 postgres postgres 0 Oct 11 10:49 pg_twophase -rwxr-xr-x 0 postgres postgres 4 Oct 11 10:49 PG_VERSION drwx------ 0 postgres postgres 0 Feb 14 13:37 pg_xlog -rwxr-xr-x 0 postgres postgres 19168 Oct 11 11:41 postgresql.conf -rwxr-xr-x 0 postgres postgres 121 Feb 17 08:57 postmaster.opts -rwxr-xr-x 0 postgres postgres 88 Feb 17 08:58 postmaster.pid I cannot perform any action on the postmaster.pid file. I tried cp, mv and rm, but nothing works. Is there anything I can do to make the system recognize this file again? And get my database up and running? Or is all hopelessly lost? I have Postgresql 9.1 installed on Ubuntu 12.04. Kind regards, Rob.
