From: Michael Grimm on 16 Jan 2010 17:09 Hi -- I'm running a gmirror raid1 plus gjournal for a year now. This is a 7.2-RELEASE-p6 right now. Both disks are regular ATA and healthy according smartctl. Whenever I beat my disks heavily, e.g. by ... dd if=/dev/null of=/some/file bs=1M count=4k plus parallel disk accesses by mail and http server. .... I'll experience sponteous reboots without any hints in logfiles. If I omit all parallel disk access those dd's will run to completion without reboots. My question is: anyone else? Regards, Michael -- to let

Questionable power supply comes to mind.

Frankely speaking, I do suspect something like ... > Questionable power supply comes to mind. .... as well. Before contacting support of my service provider I wanted to obtain feedback whether those reboots are a known issue or not. Regards, Michael -- to let |
