Hohe Festplattenlast

Hallo,

ich habe mit render_list -a -z 2 -Z 12 die Tiles erstellt. Alles soweit gut.

In dem Ordner in dem die Tiles liegen werden keine neuen Datei hinzugefügt.

Trotzdem schreibt irgendetwas mit hoher Last auf die Festplatte.

Der Server wurde bereits via Strg Alt Entf neu gestartet. Nach dem Neustart geht es dann automtisch wieder los mit der hohen Festplattenlast. Wenn rendered.Service gestoppt wird beruhigt sich die Festplatte wieder. Starte ich den rendered.Service wieder geht es wieder los mit der hohen Festplattenlast.

Kann es sein das render_list noch nicht fertig ist? Wenn dem so ist, was wird den zusätzlich zum Tiles Ordner erstellt/bearbeitet?

Danke

render_list arbeitet nach einem Reboot nicht weiter, selbst wenn es noch nicht fertig gewesen wäre.

Es gibt ein Programm namens “iotop”, mit dem Du sehen kannst, welcher Dienst für die Last verantwortlich ist. Es könnte sein, dass die PostgreSQL-Datenbank ein “autovacuum” durchführt, also ein Aufräumen der Tabellen. Das passiert von Zeit zu Zeit im Hintergrund.

Falls Du Tiles abrufst, kann es auch ohne laufendes render_list vorkommen, dass Tiles neu gerechnet werden, weil sie für veraltet gehalten werden. Das würdest Du daran sehen, dass in der Liste der laufenden Prozesse (mit “top” statt “iotop”) ein “renderd” oben steht und arbeitet.

Bye

Danke Frederik,

ich habe vergessen zu schreiben das nohup dazu benutzt wurde damit beim schliessen von putty das redern weiter geht.

Wird nach einem Neustart dann auch weiter gerendert?

Danke

nein

laut iotop hat die grösste auslastung mit ca. 97% = postgres: mapnik gis [local] SELECT

Danke

Dann renderst Du ziemlich sicher gerade Tiles - aber bestimmt nicht wegen eines vor dem Reboot abgesetzten render_list. Kann es nicht sein, dass irgendwer mit dem Browser oder wget ein Tile abgefragt hat? Auf einem Rechner ohne SSD kann schon ein einzelnes Tile zu 15minütigem Rumrödeln auf der Platte führen - wie gesagt, selbst wenn das Tile vorberechnet war und der Browser es ausgeliefert hat, kann im Hintergrund das mod_tile eine Neuberechnung gestartet haben.

ich habe jetzt den rendered.service gestoppt. nun ist alles gut. wenn ich wieder bedarf nach neuen tiles habe starte ich den rendered service wieder.

ich hoffe das ich das so machen kann!?

habe jetzt mal die postgresql.conf editiert und nun gehts.

autovacuum auf off

Wie oft aktualisierst du die Daten?

Falscher Ansatz das Problem zu umgehen.

PostgreSQL macht nur dann, wenn es aufgrund vieler Modifikationen einer Tabelle der “Meinung” ist, ein Vacuum bzw. Analyze wäre notwendig. Und das ist gut so, ansonsten sinkt die Performance deine DB zunehmend.

Nach einem Full Import der Daten sollte ebenfalls ein Analyze/Vacuum erfolgen, weil dabei die Tabellenzeilen alle “modifiziert” sind. Erst danach sind die Zugriffe per Indices optimiert. Und genau dieses scheint mMn der “störende” Autovacuum zu machen.

Lass den Autovacuum bitte 1x voll durchlaufen und schalte den Rechner nicht ab bis der durch ist. Und wenn es Tage dauert.

Gruss

lass diesen sql-script mal als postgres eingeloggt ablaufen:


select distinct ps.relname,
        seq_scan ssc,
        n_mod_since_analyze amod,
        substring(date_trunc('second',last_autoanalyze)::text,1,19) autoanalyze,
        substring(date_trunc('second',last_autovacuum)::text,1,19) autovacuum,
        analyze_count anl,
        vacuum_count vac,
        autoanalyze_count aanl,
        autovacuum_count avac
   from pg_stat_all_tables ps, pg_class pc
  where ps.relname in('planet_osm_nodes',
                   'planet_osm_line',
                   'planet_osm_point',
                   'planet_osm_polygon',
                   'planet_osm_rels',
                   'planet_osm_roads',
                   'planet_osm_ways')
 order by ps.relname;

SELECT pid,
       query,
       substring(date_trunc('second',backend_start)::text,1,19) backend_start,
       substring(date_trunc('second',query_start)::text,1,19) query_start,
       substring(date_trunc('second',now())::text,1,19) now 
  FROM pg_stat_activity 
 where query like 'autovacuum:%'
 ORDER BY query_start;


Der sollte dir alle Infos über laufende oder wartende Autovacuums geben. Ich hoffe, der ist nicht von der PostgreSQL-Version abhängig, da ich den bisher nur unter PGSQL 9.4 verwendet habe.

Danke Dir Wambacher,

ich habe autovacuum wieder auf on gestellt und den rendered.service gestartet.

# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
#   name = value
#
# (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
# "#" anywhere on a line.  The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default values.
# Re-commenting a setting is NOT sufficient to revert it to the default value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal.  If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, or use "pg_ctl reload".  Some
# parameters, which are marked below, require a server shutdown and restart to
# take effect.
#
# Any parameter can also be given as a command-line option to the server, e.g.,
# "postgres -c log_connections=on".  Some parameters can be changed at run time
# with the "SET" SQL command.

Auf den ersten Blick entdecke ich fast nix schlimmes, aber eigentlich ändert man postgresql.conf nicht mehr:

  • restauriere das Originalconfig

  • rufe in PSQL folgenden Befehl (mehrfach) auf:

    ALTER SYSTEM SET configuration_parameter { TO | = } { value | ‘value’ | DEFAULT }

z.B. alter system set shared_buffers = ‘1GB’;

Dann stehen alle config-Änderungen in postgresql.auto.config und das ist wesentlich übersichtlicher.
Die meisten Änderungen werden sofort aktiv; nur bei einigen musst du postgresql neu starten.

Und so listet du die aktiven Änderungen auf. Egal wie du das geändert hast.


SELECT name, current_setting(name), source
   FROM pg_settings
 WHERE source NOT IN ('default', 'override')
 ORDER BY name;

ps: shared_buffers=128MB ist verdammt wenig. du hast 32 GB und solltest da grosszügiger sein.

Ich habe jetzt mal auf shared_buffers=8GB gesetzt.

Kann man das rendern optimieren. Es sollen keine neuen tiles erstellt werden nur weil das Datum zu alt ist etc.

Ich habe in der renderd.conf nichts dazu gefunden.

ich möchte das rendern immer manuell starten.
