[ProxMox VE] Web login issue, I/O errors in daemon.log

[iGadget]

Op mijn thuis servertje heb ik ProxMox VE 6.1-7 draaien op een Dell OptiPlex 7010 met een Samsung EVO 840 SSD. Heeft maanden lang als een zonnetje gedraaid. Een paar dagen geleden zag ik bij toeval dat de automatische snaphot van 1 van de LXC hosts niet was gelukt. Bij een snelle blik op de log sprongen de woorden 'I/O error' in het oog. Op dat moment had ik geen tijd om er verder in te duiken, maar inmiddels is het probleem geescaleerd.
Sinds vandaag kan ik niet meer inloggen op de Web GUI, foutmelding 'Login failed. Please try again'.
Gelukkig kan ik nog wel met SSH op de machine komen.

In /var/log/daemon.log zie ik dit:

code:

Nov 23 10:00:10 server systemd[1]: Failed to start Proxmox VE replication runner.

Als ik echter 'dmesg' intik, zie ik helemaal niets voorbij komen wat wijst op hardware errors.

Output van smartctl -t short -a /dev/sda:

Misschien lees ik niet goed, maar ik maak uit de data hierboven niet op dat mijn SSD serieuze problemen heeft. Mis ik iets?
Zijn er nog andere dingen die ik moet doen of kan proberen?

Relevante software en hardware die ik gebruik
- ProxMox VE 6.1-7
- Dell OptiPlex 7010, 8GB werkgeheugen
- Samsung EVO 840 250GB SSD

Wat ik al gevonden of geprobeerd heb

Na het toevoegen van de pve-no-subscription repo (instructies via https://www.caretech.io/2...ut-buying-a-subscription/), een apt update && apt dist-upgrade en een reboot werkte alles weer. Kennelijk een software glitch...
