NethServer Version: NS8
Module: Disaster Recovery
Hi Everyone:
I am trying to do a disaster recovery of an NS8, but it does not work. (Nothing restored and “no application to restore” )
I now tried to do the disaster recovery in a LAB, but have the same result.
STEPS in LAB:
- Create VM (Rocky linux 9.7) installing Nethserver with curl.
- Configure SAMBA, install Mail, SOGo, Nextcloud and Wordpress as test, creating a single account, creating a test site on wordpress, and import few contacts and calendar in SOGO as a single node cluster.
- Configured Backup as per documentation to local storage (usb ssd passed through to the VM) and ran the backup successfully.
- Downloaded the cluster backup.
- Creted another VM with the same IP address and hostname, installing rocky linux and nethserver the same way as the first one.
- Followed disaster recovery from here : Backup and restore — NS8 documentation
- After step 5 (Enter the encryption secret in the Backup password field.) it is displaying “restoring cluster” without offering any option which application to restore.
- Once it is finished, the only thing that is configured is the backup destination. → no SAMBA or any other application.
- Upon clicking on Restore tab → Restore application, in the pop up window “No application to restore” shows up.
In the logs there is only 1 error:
level=ERROR source=diskstats_linux.go:256 msg=“Failed to open directory, disabling udev device properties” collector=diskstats path=/run/udev/data
Can someone please tell me what i am doing wrong?
