ZFS lay out many filesystems on a single or more partitions, beyond other choices ...

NAME
findfs - find a filesystem by label or UUID
SYNOPSIS
findfs NAME=value
DESCRIPTION
findfs will search the block devices in the system looking for a filesystem or partition with specified tag. The currently supported tags
are:
LABEL=<label>
Specifies filesystem label.
UUID=<uuid>
Specifies filesystem UUID.
PARTUUID=<uuid>
Specifies partition UUID. This partition identifier is supported for example for GUID Partition Table (GPT) partition tables.
PARTLABEL=<label>
Specifies partition label (name). The partition labels are supported for example for GUID Partition Table (GPT) or MAC partition
tables.
If the filesystem or partition is found, the device name will be printed on stdout.
The complete overview about filesystems and partitions you can get for example by
lsblk --fs
partx --show <disk>
blkid
EXIT STATUS
0 success
1 label or uuid cannot be found
2 usage error, wrong number of arguments or unknown option
