PBS data pool lost after reboot and no incremental backup

[supermicro_server]

Hello all,
I have below system:
Backup Server 1.0-6
Disc:
2 small SSD dedicated for OS (ZFS mirror ) name: rpool
4 SATA 1TB dedicated for data pool (raidz-1) name: Storage1
The healty of all disk are ok!
The system run well!

sometime, after the reboot, PBS lose the data pool Storage1 (not mounted durning the boot)

I have to send command to import pool:
zpool import -F Storage1

Someone can explane me why PBS sometime lose the pool?

After manual pool import, happen a strange thing with tha backup.
The backup duration increase a lot. It seems the backup start again totaly and not incremental.

Somewone can explane me why?

Thanks
Alessandro

Have you checked the syslog/journal for any errors when importing the pool during the boot?

Was the zpool imported during that boot or was it one where it did not?
If it was one that worked, take a look at the logs where it did not work.

Please also provide the complete output of proxmox-backup-manager versions --verbose

The easiest way to get the log would be to use journalctl. Run journalctl -b > journal.txt and then attach the file here.

File updated!
Important: in the last boot the "Storage1" pool was montag correctly on boot.
no need manually importation!
