NAME

vdoreadonly - puts a VDO device into read-only mode

SYNOPSIS

vdoreadonly filename

DESCRIPTION

vdoreadonly forces an existing VDO device into read-only mode.

filename must be the path of the VDODataLV as described in lvmvdo (7). Since lvchange (8) will only mount that as read-only, a writable version of that device must be manually created, as shown in the example below.

OPTIONS

--help

Print this help message and exit.

--version

Show the version of vdoreadonly.

EXAMPLE

# lvchange -ay vdo1/vdo0pool_vdata
# dmsetup table vdo1-vdo0pool_vdata > vdata.table
# lvchange -an vdo1/vdo0pool_vdata
# dmsetup create vdo1-vdo0pool_vdata --table "‘cat vdata.table‘"
# vdoreadonly /dev/mapper/vdo1-vdo0pool_vdata
# dmsetup remove vdo1-vdo0pool_vdata
