So the misleading "raid0" is shown in this testcase. I think maybe
the "Raid Level" item shouldn't be displayed any more for the inactive
array.
As a system administrator, I'd much rather see "unknown" (or something
similar), rather than simply omitting the information.
Thanks for the suggestion.
Yeah, just removing the Raid Level info is not the best option. I also
considered to show it as "inactive Raid1" in such case.
If it would be a raid1 when activated, it is still a raid1 when
inactive: the data on disk doesn't suddenly become not a raid array
simply because the kernel isn't able to access it right now. This is
valuable information to expose to the sysadmin and should not be
concealed (and *certainly* not described as a raid level it actually
isn't).
I think it should say as much (if the system knows at this stage, which
if there is a device node, it presumably does).
