It seems I can't smarm monitor disks on RAID controllers? I tried on several machines with two different controllers and on all I get this when starting up smartd: Jul 27 14:36:43 c1 smartd[5944]: Opened configuration file /etc/smartd.conf Jul 27 14:36:43 c1 smartd[5944]: Configuration file /etc/smartd.conf parsed. Jul 27 14:36:43 c1 smartd[5944]: Device: /dev/sda, opened Jul 27 14:36:43 c1 smartd[5944]: Device: /dev/sda, Bad IEC (SMART) mode page, err=4, skip device Jul 27 14:36:43 c1 smartd[5944]: Unable to register SCSI device /dev/sda at line 32 of file /etc/smartd.conf Jul 27 14:36:43 c1 smartd[5944]: Device /dev/sda not available /dev/sda is the virtual disk as it appears to CentOS as I can access it with hdparm. Do I need to use another device for the RAID array (which?) or is it impossible to smart monitor "thru" a RAID controller?
