vdoforcerebuild - Man Page

prepare a VDO device to exit read-only mode

Synopsis

vdoforcerebuild filename

Description

vdoforcerebuild forces an existing VDO device to exit read-only mode and to attempt to regenerate as much metadata as possible.

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

# dmsetup create vdo1-vdo0pool_vdata --table "`cat vdata.table`"
# vdoforcerebuild /dev/mapper/vdo1-vdo0pool_vdata
