HOME Directory containing .lvm_history if the internal readline
shell is invoked.

File descriptor to use for common output from LVM
commands.
LVM_ERR_FD
File descriptor to use for error output from LVM commands.
LVM_REPORT_FD
File descriptor to use for report output from LVM
commands.
LVM_COMMAND_PROFILE

This profile is overridden by direct use of
--commandprofile command line option.
LVM_RUN_BY_DMEVENTD
This variable is normally set by dmeventd plugin to inform
lvm2 command it is running from dmeventd plugin so lvm2
takes some extra action to avoid communication and
deadlocks with dmeventd.
LVM_SYSTEM_DIR
Directory containing lvm.conf(5) and other LVM system
files. Defaults to "/etc/lvm".
LVM_SUPPRESS_FD_WARNINGS

into LVM.
LVM_SUPPRESS_SYSLOG

a Logical Volume that doesn't specify a path. Not set by
default.
LVM_LVMPOLLD_PIDFILE

LVM_LOG_FILE_EPOCH
A string of up to 32 letters appended to the log filename
and followed by the process ID and a startup timestamp
using this format string "_%s_%d_%llu". When set, each
process logs to a separate file.
LVM_LOG_FILE_MAX_LINES
If more than this number of lines are sent to the log
file, the command gets aborted. Automated tests use this
to terminate looping commands.
LVM_EXPECTED_EXIT_STATUS
The status anticipated when the process exits. Use ">N"
to match any status greater than N. If the actual exit
status matches and a log file got produced, it is deleted.
LVM_LOG_FILE_EPOCH and LVM_EXPECTED_EXIT_STATUS together
allow automated test scripts to discard uninteresting log
data.

locking is known to be unavailable.
DM_ABORT_ON_INTERNAL_ERRORS
