No, basically you have to proceed without metadata. Unless the OS this was at some point connected to still exists and has metadata in /etc/lvm. If the LV was not fragmented you could possibly treat this as a "lost partition table" with testdisk. Otherwise it's a puzzle. I don't have a specific answer here, sorry. See if you can find any filesystem headers, and into the rabbit hole from there. Or see if photorec finds anything (regardless of filesystem).

Unfortunately no logical_volumes { ... shown here. Same for the other drive?

| Apr 15 at 12:20 | comment | added | Testy Testy | Added output of your suggestion "head -c 1M /dev/sdb1 | strings -w" above. Many thanks frostschutz. Unfortunately, this was a pure data disk with OS installed on another physical drive. | |

testdisk alone might help if LVs were linear and unfragmented (created directly, never removed, never resized, ...). In this case you could map LVs to regular partitions. Otherwise, do you have backup LVM metadata (usually under /etc/lvm/{backup,archive}/...)? Does head -c 1M /dev/sdx1 | strings -w show any LVM metadata? If the rootfs /etc was inside the LVM itself and not encrypted, you could strings the entire drive to search for it (# Generated by LVM2 or similar).
