Dear Stanislav, dear smartmontools developers,

I've upgraded one of my servers to smartmontools 6.1 today, that happens to drive a Areca SAS controller, specifically:

<5>[ 7.206669] Areca RAID Controller6: F/W V1.46 2009-01-06 & Model ARC-1680 <6>[ 7.270516] scsi6 : Areca SAS Host Adapter RAID Controller( RAID6 capable) <6>[ 7.270516] Driver Version 1.20.00.15 2010/08/05

Thing is, the system freezes immediately after running (updating) smartd. rpm stopped at 89%, and the system was *locked*. While I can switch consoles, even Sys-Req S and U doesn't finish anymore, while B worked. :-(

Sounds scary. Please do some tests:

1) Test on smartd from fresh svn to make sure that local patches are not affecting the result. 2) Test if smartctl --scan and --scan-open commands works. 3) try to run it with smartd -d -r ioctl and provide resulted output.

Will do that soon (hopefully I can do these tests in single user mode).

Also i would recommend to make sure that RAID firmware is up to date, because this could be caused by wrong firmware.

Honestly, I don't buy this argument. This behavior points to a serious *kernel* problem in this area, since a system app, even running as root, should never ever be able to firmly lock the system, no matter what firmware version it is running. But such issues must be analysed and fixed, of course.. This mail was intended to both: warn users about it, and harvest some hints on how to preceed.
