Hi,
Is there a way to list the _number_ in addition to the name of a
problematic component? The kernel trend to move all block devices into
the sdX namespace combined with the dynamic name allocation renders
messages like "/dev/sdc1 has problems" meaningless. It would make remote
server support so much easier, by allowing the administrator to label
drive trays Component0 Component1 Component2... etc, and be sure that
the local tech support person will not pull out the wrong drive from the
system.
Any takers? Or is it a RTFM question (in which case I certainly
overlooked the relevant doc)?
If you use udev, have you looked in /dev/disk? I think it solves the
problem you need by allowing one to see either the disks by id or by
path. Making the reverse map is then trivial (for a reasonable number of
disks).
This would not work as arrays are assembled by the kernel at boot time,
at which point there is no udev or anything else for that matter other
than /dev/sdX. And I am pretty sure my OS (debian) does not support udev
in initrd as of yet.
