Bug#932791: mdadm: inconsistent documentation
Package: mdadm
Version: 4.1-1
Severity: minor
Dear Maintainer,
there seem to be inconsistencies between the man page and the help
output
The 'man mdadm' prints out
mdadm [mode] <raiddevice> [options] <component-devices>
but
'mdadm --manage -h'
says
Usage: mdadm arraydevice options component devices...
Shouldn't the later say
Usage: mdadm mode arraydevice options component devices...
What's the right and/or 'official' sequence of options and parameters?
Greetings
Tobias
