NAME¶

vdosetuuid - sets a new uuid for the vdo volume stored on a backing store

SYNOPSIS¶

vdosetuuid [options...] vdoBacking

DESCRIPTION¶

vdosetuuid sets a new uuid for the VDO volume stored on the vdoBacking device.

vdoBacking 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.

--uuid

Sets the uuid value that is stored in the VDO device. If not specified, the uuid is randomly generated.

--version

Show the version of vdosetuuid.

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`"
# vdosetuuid --uuid 6ecb9db8-[...] /dev/mapper/vdo1-vdo0pool_vdata
# dmsetup remove vdo1-vdo0pool_vdata
