[smartmontools-support] DEVICESCAN and SATA drives

[Michael L. <mi...@la...>]

hi all,
i just installed smartmontools and find it very useful.
allthough i have some troubles with the devicescan option.
i use DEVICESCAN because i have different types of drives in my systems (
some ATA, some SATA, on some both).
here is the problem i encounter
when i set nothing but DEVICESCAN i get

above. Try adding \'-d ata\' to the smartd.conf config file line.

when i use -d ata the /dev/sd* devices do not even get scanned.
 
one solution would be to add 4 entries into /etc/smartd.conf which i don't
want ( i want one config for all systems).
i patched os_linux.c (or hacked ? ;) like

This way all devices get scanned and i force '-d ata'.
I think the "right" solution would be to not drop /dev/sd* devices when
nothing gets set an ddevicescan is used and rather the libara access method
is used.
