How forceful is shutdown -h ?

[gregorypeck]

Just wondering:
If we run (as root) shutdown -h in the Proxmox shell and we have a couple of backups/snapshots which need another couple of hours until finished, will they be interrupted/fail by shutdown?

Yes they will interrupt the backup process, and if you enabled reporting per mail it will list it as failed
When you issue a :

• init 6
• shutdown -h
• shutdown -r
• reboot

it will stop the service that is running the backup as its being overruled from system itself and in the report (if emailing it is enabled) you will see :

interrupted by signal

On the VM/CT it was trying to backup.

all consecutive ones in the backup-Job will be listed as :

aborted

Hmm... Thanks. Is there any quick command line request I could pass through a script to check if there are any backup/snapshot proecesses running at present?

Not as far as i know, only indication i have of jobs running is the view of the webUI ( i must confess i have not looked into it deeper)

Also a thing i have not found ( if it is even built-in) .. if a job is interrupted a way to start/continue where it left off.

i mean for example:

• backupjob has 4 CT/VM's configured
• backup of guest 1 is complete
• reboot is initiated
• backup re-starts at VM/CT 2 (as VM/CT was successfull) after reboot.

From what i know the full backupjob is killed, and after the host comes back up a resume is not attempted.
