thanks.
you`re lucky that i could test it, as this server is already in production, but
i had a timeslot for maintenance today and dared installing a second kernel,
risking to trash the system.
don`t tell my chief, shhhh ;)
anyway, thanks for the patch.
it seems to fix the issue to some degree, but it seems it`s not the perfect
solution, as the behaviour looks racy now, i.e. i could crash the system
reliably before - now it only crashes sporadically on smartd start.
so the fix seems to point into the right direction.
this is what smartd -d MAY respond with the patch applied:
smartd 5.39 2009-08-08 r2872~ [i686-pc-linux-gnu] (openSUSE RPM)
Copyright (C) 2002-9 by Bruce Allen, http://smartmontools.sourceforge.net
Opened configuration file /etc/smartd.conf
Drive: DEVICESCAN, implied '-a' Directive on line 26 of file /etc/smartd.conf
Configuration file /etc/smartd.conf was parsed, found DEVICESCAN, scanning
devices
glob(3) found no matches for pattern /dev/hd[a-t]
Device: /dev/sda, opened
Device: /dev/sda, Bad IEC (SMART) mode page, err=5, skip device
Unable to register SCSI device /dev/sda at line 26 of file /etc/smartd.conf
Unable to monitor any SMART enabled devices. Try debug (-d) option. Exiting...
running several "smartd -d" one after the other still crashes the system.
running smartd -d in a loop reliably crashes the system , mostly within 10 or
20 execs of smartd.
regards
Roland
