Unable to migrate a subscription to Plesk: Disk quota exceeded

Symptoms

Migration to Plesk fails with an error like the following:

CONFIG_TEXT: command: su plesk-migrator-wzt0sv4doqtw2mj5 --shell /bin/sh -c 'mkdir -m 755 /home/plesk-migrator-wzt0sv4doqtw2mj5/.ssh && echo '"'"'ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCzW6CaeU9clduXL07cxn02UZCqQ7jkRHhdvgfwyowOleTMVtjQoEWse8c8bVd2kZgA4ndf1FwFZopsghoc7KtqKMWP1J1a1Bhpp6dyBicUy2xFYc0hNAmHyZqwipqkE1EpHSm8PgVj75rmT/d0YMobrAGe1XOXVt admin_1@example.com'"'"' > /home/plesk-migrator-wzt0sv4doqtw2mj5/.ssh/authorized_keys && chmod 644 /home/plesk-migrator-wzt0sv4doqtw2mj5/.ssh/authorized_keys'
exit code: 1
stdout:
stderr: mkdir: cannot create directory `/home/plesk-migrator-wzt0sv4doqtw2mj5/.ssh': Disk quota exceeded

Cause

Disk quota is enabled on the source server for Plesk migrator users.

This behavior is also considered as Plesk Migrator bug with ID #PMT-3527, which will be fixed in the future versions of the extension.

Resolution

1. Connect to the server via SSH to the source server.

2. Increase or disable disk quota temporally using the OS documentation.
