VZFASTBOOT

This option determines the Container quota reinitialization procedure when the Hardware Node is booted after an incorrect shutdown. If set to “no”, the disk quota is reinitialized for each Container during the Node startup and only then are the Containers started, which results in a long Hardware Node and Containers booting time. When set to “yes”, the Container quota reinitialization procedure depends on the Container quota files state:

Those Containers whose quota files (/var/vzquota/quota.) have a “dirty” flag set, meaning that their contents are inconsistent with the real Containers usage, are started without the quota reinitialization. After all the Containers with “dirty” flags are launched, they are restarted one by one to reinitialize their respective quotas.
Those Containers whose quota files are absent from the Node or corrupted are started only after their quota has been successfully reinitialized.

In general, setting the VZFASTBOOT parameter to “yes” allows you to considerably reduce the Hardware Node and Containers downtime after the incorrect Node shutdown.
