14 drives in 1 case? That's a big box! Did you ask your kids for help? :) Guy -----Original Message----- From: linux-raid-owner@xxxxxxxxxxxxxxx [mailto:linux-raid-owner@xxxxxxxxxxxxxxx] On Behalf Of comsatcat Sent: Tuesday, December 14, 2004 3:29 AM To: Guy Cc: linux-raid@xxxxxxxxxxxxxxx Subject: RE: Busted disks caused healthy ones to fail The two disks that were actually dead were both on a different bus. The OS disk that died was on scsi0. Is there a way around this behavior (ie: kernel params that can be adjusted such as timeout values and queuing)? It never really recovered correctly after the disks died, a manual reboot as required. Applications which were using the failed devices would hang forever (I'm assuming they were waiting for queued commands to complete). IDE: not in use Power: 14 internal drives, no external Temp: fust fine Kids: Upstairs taking tech calls.
