NAME¶

vdoregenerategeometry - regenerate a VDO whose first few blocks have been wiped

SYNOPSIS¶

vdoregenerategeometry [options...] filename

DESCRIPTION¶

vdoregenerategeometry will attempt to regenerate the geometry block of a VDO device in the event that the beginning of the backing store was wiped. This tool will fail if enough of the device was wiped that the VDO super block was also erased, or if there are multiple valid super block candidates on the volume.

If the super block location is known, or to select one of the candidate super blocks in the event that multiple candidates were found, the --offset option can be used to specify the location (in bytes) of the super block on the backing store.

OPTIONS¶

--help

Print this help message and exit.

--offset

Specify the location (in bytes) of the super block.

--version

Show the version of vdoregenerategeometry.
