Correction to 2nd sentence: "Whenever I restart after a proper shutdown, ..." should be "Whenever I restart after an improper shutdown, ...". Git commit f217d9e96dc8de88916e8ca0b93dd9a7500bbbc3 by Dan Vrátil. Committed on 06/05/2014 at 14:38. Pushed by dvratil into branch '1.12'. Fix PostgreSQL start when postmaster.pid is not removed after non-clean shutdown When PostgreSQL is not terminated nicely, a pidfile is left behind in db_data, which will prevent pg_ctl from starting a new PostgreSQL server. We check for postmaster.pid file and verify that postgres server with PID specified in the pidfile is not running anymore, then delete the pidfile to allow pg_ctl to start a new server. If the postgres server is still running (possibly after Akonadi server crash), we try to connect to it right away.

Version: 4.7 (using KDE 4.7.3) OS: Linux Sometimes my system crashes, some times when my battery dies or when my laptop doesn't wake up from sleep/hibernation. Whenever I restart after a proper shutdown, the akonadi server doesn't start - because the postgresql lock file is still in place. Reproducible: Always Steps to Reproduce: Use an internatl postgresql server backend for akonadi. After a forced shutdown or crash, boot. Akonadi won't start. Try starting it manually, same results. Actual Results: /home/[user]/.local/share/akonadi/db_data/postmaster.log will tell you the reason: 2011-11-17 07:14:48 GMT FATAL: lock file "postmaster.pid" already exists 2011-11-17 07:14:48 GMT HINT: Is another postmaster (PID 4637) running in data directory "/home/alvanx/.local/share/akonadi/db_data"? 2011-11-17 08:14:55 CET FATAL: lock file "/home/alvanx/.local/share/akonadi/socket-alvanx/.s.PGSQL.5432.lock" already exists 2011-11-17 08:14:55 CET HINT: Is another postmaster (PID 4655) using socket file "/home/alvanx/.local/share/akonadi/socket-alvanx/.s.PGSQL.5432"? Deleting the latter lock file solved the problem for me. (The lock file "postmaster.pid" did not seem to be relevant for this particular problem.) Expected Results: Akonadi or the server or whatever should somehow understand what happened. Maybe it needs another way to doublecheck if the database server is already running? I am really a noob at this, but I do know a bug when I see one, even if it may only be a usability bug. At the very least, the akonadi backtrace should offer sufficient information right upfront to allow the user to track down the problem right away so he can check for himself. Here is the error log file: Akonadi Server Self-Test Report =============================== Test 1: SUCCESS -------- Database driver found.

Result: Akonadi 1.6.0 Test 4: ERROR -------- Akonadi control process not registered at D-Bus. Details: The Akonadi control process is not registered at D-Bus which typically means it was not started or encountered a fatal error during startup. Test 5: ERROR -------- Akonadi server process not registered at D-Bus. Details: The Akonadi server process is not registered at D-Bus which typically means it was not started or encountered a fatal error during startup. Test 6: SUCCESS -------- Nepomuk search service registered at D-Bus. Details: The Nepomuk search service is registered at D-Bus which typically indicates it is operational. Test 7: SUCCESS -------- Nepomuk search service uses an appropriate backend. Details: The Nepomuk search service uses one of the recommended backends. Test 8: SKIP -------- Protocol version check not possible. Details: Without a connection to the server it is not possible to check if the protocol version meets the requirements. Test 9: ERROR -------- No resource agents found. Details: No resource agents have been found, Akonadi is not usable without at least one. This usually means that no resource agents are installed or that there is a setup problem. The following paths have been searched: '/usr/share/akonadi/agents'. The XDG_DATA_DIRS environment variable is set to '/usr/local/share:/usr/share:/etc/opt/kde3/share:/opt/gnome/share:/opt/kde3/share'; make sure this includes all paths where Akonadi agents are installed.
