LVMetaD socket operates in non-blocking mode. 2012-02-28 17:07:03 +04:00			`NonBlocking=true`
Add LVMetaD systemd units. 2012-02-23 15:24:07 +04:00			`ExecStart=@sbindir@/lvmetad`
Use pvscan --cache instead of vgscan in lvmetad init script and systemd unit. 2012-03-16 19:12:04 +04:00			`ExecStartPost=@sbindir@/lvm pvscan --cache`
Add LVMetaD systemd units. 2012-02-23 15:24:07 +04:00			`ExecReload=@sbindir@/lvmetad -R`
Use SD_ACTIVATION env. var. in systemd units to better detect systemd in use. LISTEN_PID and LISTEN_FDS environment variables are defined only during systemd "start" action. But we still need to know whether we're activated during "reload" action as well - we use the reload action to call "dmeventd -R"/"lvmetad -R" for statefull daemon restart. We can't use normal "restart" as that is simply composed of "stop" and "start" and we would lose any state the daemon has. 2012-03-14 19:51:51 +04:00			`Environment=SD_ACTIVATION=1`
Add 'Restart: on-abort' for lvmetad systemd service. Restart lvmetad automatically if it exits due to reception of uncaught signal, leaving a track in systemd log/syslog. 2012-03-08 13:49:09 +04:00			`Restart=on-abort`
Use DEFAULT_RUN_DIR instead of hardcoded value in lvmetad systemd units and add ExecStartPost=vgscan to actually run the first scan that will fill the metadata daemon with metadata information. 2012-02-23 17:31:49 +04:00			`PIDFile=@DEFAULT_RUN_DIR@/lvmetad.pid`
