Hi all,
i had just an freezed clusternode during an postgresql-db-import in an openvz-vm.
The first import breaks, and the second gives a lot of duplicate key value (that's normal because i don't drop the database before).
Suddenly the error-messages stop and a top on the pve-host show an high load:
The load rise up to 7.33 (nine second later) and the whole node freezed. After reset there was nothing in the logs...
Version:
After reboot i do the same - but now the database was imported without trouble.
How can it happens that pvestatd and pvedaemon block the system?
I guess it's not an io-problem, because the processes has an high cpu-usage - if they wait for io it should look different.
