`rake posts:rebake` ist auf halbem Weg abgestürzt

Unterstützung Installation
1

Hallo, ich habe auf meiner Testumgebung rake posts:rebake ausgeführt, was normalerweise über 24 Stunden in Anspruch nimmt. Heute Morgen habe ich mich in die Sitzung eingeloggt und festgestellt, dass sie bei etwa 50 % abgestürzt ist. Ich glaube nicht, dass es an einem Speichermangel lag, da der VPS über 8 GB RAM und 15 GB Swap verfügt. Auch mein angepasstes Drupal-Import-Skript ist vor einigen Tagen während des Importvorgangs einmal aufgrund eines Postgres-Fehlers abgestürzt. Das gleiche Import-Skript habe ich bereits mehrfach erfolgreich ausgeführt, ebenso wie mindestens eine vollständige rake posts:rebake. Ich habe das damals als Zufall abgetan, aber diesmal scheint es wieder ein weiteres zufälliges Problem mit Postgres zu sein:

Hallo!

Es klingt, als ob Ihr Postgres-Status auf der Festplatte schlecht ist, entweder aufgrund eines bestimmten Korruptionsereignisses oder eines fortlaufenden Problems, wie z. B. Dateisystemkorruption oder zugrunde liegende Festplatten-/Speicherhardwarefehler in Ihrem VPS.

Versuchen Sie zunächst, fsck auf Ihrem Dateisystem auszuführen.

Als Nächstes: Wenn es sich um ein Testsystem handelt und Sie die Daten neu erstellen können, versuchen Sie, von vorne mit PG zu beginnen, indem Sie das Datenverzeichnis vollständig entfernen und eine neue Datenbank erstellen. Versuchen Sie dann, die Dinge durch erneutes Importieren/Erstellen zu belasten, um zu sehen, ob das Problem weiterhin besteht.

Vielen Dank @leonardo für die Tipps.

Wenn ich jetzt darüber nachdenke, erinnere ich mich, dass der vorherige Absturz, den ich letzte Woche während des Imports hatte, speziell auf einen Postgres-Fehler wegen doppelter Schlüssel zurückzuführen war, also diesmal ein anderer Fehler.

Ich habe ein xfs_repair mit der Option -e ausgeführt, sodass es nach meinem Verständnis keine Beschädigung gibt:

xfs_repair -e /dev/sda2
Phase 1 - find and verify superblock...
Phase 2 - using internal log
        - zero log...
        - scan filesystem freespace and inode maps...
        - found root inode chunk
Phase 3 - for each AG...
        - scan and clear agi unlinked lists...
        - process known inodes and perform inode discovery...
        - agno = 0
        - agno = 1
        - agno = 2
        - agno = 3
        - agno = 4
        - agno = 5
        - agno = 6
        - agno = 7
        - agno = 8
        - agno = 9
        - agno = 10
        - agno = 11
        - agno = 12
        - agno = 13
        - agno = 14
        - agno = 15
        - agno = 16
        - process newly discovered inodes...
Phase 4 - check for duplicate blocks...
        - setting up duplicate extent list...
        - check for inodes claiming duplicate blocks...
        - agno = 0
        - agno = 3
        - agno = 1
        - agno = 2
        - agno = 4
        - agno = 5
        - agno = 6
        - agno = 7
        - agno = 8
        - agno = 9
        - agno = 10

        - agno = 13
        - agno = 14
        - agno = 15
        - agno = 16
clearing reflink flag on inodes when possible
Phase 5 - rebuild AG headers and trees...
        - reset superblock...
Phase 6 - check inode connectivity...
        - resetting contents of realtime bitmap and summary inodes
        - traversing filesystem ...
        - traversal finished ...
        - moving disconnected inodes to lost+found ...
Phase 7 - verify and correct link counts...

EDIT: Nach dem Neustart (ich habe das Rettungssystem verwendet, um fsck auf dem nicht gemounteten Dateisystem auszuführen) würde die Discourse-App starten und es gab keine Fehler in den Protokollen, aber ich bekam nur den White Screen of Death. Ich musste die App neu erstellen, damit die Website wieder geladen wurde. Ich bin mir wirklich nicht sicher, was bei all dem schiefgelaufen ist.
