version 27 upgrade issues

After upgrading to parallels pro 27
- my external thunderbolt disks no longer mount properly inside the linux virtual machine. They are still visible using lsblk, so maybe their ids changed?
- the host system (mac os 15) seems less stable. I could not log back in without a full reboot.
 
Some info gathered from ubuntu after I downgraded to 26:

- This has happened on the last six boots today.
- Earlier boots through August 27 imported successfully.
- All three disks subsequently appear with matching pool metadata at transaction group
3499600.

- No disk, SATA-link, or I/O errors appeared in the kernel log.
- The cache contains the correct persistent /dev/disk/by-id/... paths.

This points to a boot-time device-discovery race, likely involving the Parallels-provided
SATA disks. The import runs before enough device nodes or by-id links are usable. Once
startup finishes, the pool is fully discoverable. The alarming “destroy and re-create”
message is generic and does not reflect the pool’s present condition.
