After ~4 sec secondary controller become primary. Sometimes hung processes get running immediatery. But sometimes unhangs only after 60 sec. Also after controller reset (it takes 1-2 minute) some directories became empty, another ones unreadable -- read operation returns 'Device not configured'. The questions are: 1. Is it FreeBSD's or IFT's bug ? 2. Does anybody know solution/workaround ? 3. 'Disconnection' enabled on RAIDcontroller and on-board scsi controller on hosts, is it correct ? 4. Does anybody have expirience maintaining servers without local disk (external only) ? Are there any troubles ? Any help would be greatly appreciated.
