PVE does not create or destroy zpools anywhere in the code base[1].

Exporting a pool does not destroy it either - either you have some other
piece of software / script / .. installed that triggered the destroy
operation, or you (or someone else with access to your host)
accidentally destroyed the pool instead of exporting it when interacting
with the "zpool" binary.. I recommend checking other log files and
shell histories, maybe you can find the origin of the destroy action.

You might be able to recover a recently destroyed pool by importing it
with "-D" - of course that will only work if you haven't yet overwritten
the disks/partitons/.. .

1: except for the installer of course, and some test suites that are
only run at build time and which use file-backed vdevs
