Maybe you need to tune the filter rules in /etc/lvm/lvm.conf.

My own rules as an inspiration:
    # Do not scan ZFS zvols (to avoid problems on ZFS zvols snapshots)
    global_filter = [ "r|/dev/zd.*|", "r|/dev/mapper/pve-.*|" ]

    # Only scan for volumes on local disk and on iSCSI target from Qnap NAS. Block scanning from all
    # other block devices.
    filter = [ "a|ata-OCZ-AGILITY3_OCZ-QMZN8K4967DA9NGO.*|", "a|scsi-36001405e38e9f02ddef9d4573db7a0d0|", "r|.*|" ]
