mount LVM2 dump or extract files

I have a dump of a filesystem. I dont know how it was created. I want to extract all the files and the filestructure.

file dump.bin says it is a LVM2 PV (Linux Logical Volume Manager) file and prints a UUID and the size. I tried to use kpartx like this: sudo kpartx -a -v dump.bin but there are no partitions in /dev/mapper/ afterwards.

When I cat the file, it starts with imageUSB and is followed with content like this:

uarea {
id = "xxxx-xxxx-xxxx-xxxx"
seqno = 1
format = "lvm2"
status = ["RESIZEABLE", "READ", "WRITE"]
flags = []
extent_size = 2048
max_lv = 0
max_pv = 0
metadata_copies = 0

physical_volumes {

pv0 {
id = "xxxx-xxxx-xxxx-xxxx"
device = "/dev/sda"

status = ["ALLOCATABLE"]
flags = []
dev_size = xxxx
pe_start = xxxx
pe_count = xxxx
}
}


}
# Generated by LVM2 version ....

How can I mount the filesystem or extract all files and the filestructure?

I already tried to use binwalk to extract all files, but it crashes because no memory is left, I guess because the dump is too big.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
