[smartmontools-support] smartmontools-7.1 reports "logging not supported" while 7.0 works as expected

[Marcus Mülbüsch]

Hello all

with smartmontools-7.0 everything was fine and I can read all the logs 
(note that I cut the information section; that remains unaffected by the 
behaviour)

while with smartmontools 7.1 the same server with the same HD reports 
that logging is not supported and no temperatures are read:

(Output stops here)

I just updated on gentoo and this behaviour seems strange. When I 
downgrade to 7.0 everything works fine again.

I updated the drivedeb, but there is no difference to the result. I 
tried with the old drivedb, but there still is no difference.

Servers are HP ProLiant G7 with "RAID bus controller: Hewlett-Packard 
Company Smart Array G6 controllers (rev 01)", while HDs are "146GB 
hot-plug dual-port SAS hard disk drive - 10,000 RPM, 6Gb/sec transfer 
rate, 2.5-inch small form factor (SFF), Enterprise"; but the behaviour 
does not depend on the HD used.

smartd is not affected and the csv written since the update do not 
differ from those before. Especially the temperature *is* logged (and 
seems correct)

Am I missing something?

Thanks,

Marcus
