Running smartd or smartctl prints to system log lots of these: "program smartd is using a deprecated SCSI ioctl, please convert it to SG_IO" -kernel-utils-2.4-13.1.39 -kernel-2.6.9-1.667
Increasing Priority. With new 2.6.10-1.737_FC3 kernel the problem became worse. I can not used smartd at all: /usr/sbin/smartctl /dev/sda -d 3ware,0 -H -A smartctl version 5.33 [i386-redhat-linux-gnu] Copyright (C) 2002-4 Bruce Allen Home page is http://smartmontools.sourceforge.net/ SMART support is: Ambiguous - ATA IDENTIFY DEVICE words 82-83 don't show if SMART supported. A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options. On system log: Jan 11 18:44:47 monster kernel: program smartctl is using a deprecated SCSI ioctl, please convert it to SG_IO Jan 11 18:44:47 monster kernel: 3w-xxxx: SCSI_IOCTL_SEND_COMMAND deprecated, please update your 3ware tools.
Use /usr/sbin/smartctl /dev/twe0 -d 3ware,0 -H -A See this thread: http://sourceforge.net/mailarchive/forum.php?thread_id=8834747&forum_id=12495
