The drive doesn=C2=B4t show up but th= erein ends the similarities. OK, driver timeout is more appropriate but lies at the OS level, as opposed= to setting in HBA or HDD firmware, is what I meant. There are no simple reproduction steps I can provide because I can=C2=B4t r= eally make it happen at will, but it has happened quite frequently as of late. Wh= at I can tell you are how the systems are setup. You start with some hardware, add a HBA of either model 9200, 9201, 9211 or AOC-USAS2-L8(i|e) flashed with IT FW, connect them through some kind of expander and add at least 14 drives. That=C2=B4s the least amount of drives= where I=C2=B4ve seen this issue occur. Install latest FreeBSD release and opt for= "Auto ZFS", apply some pressure (preferably external over NFS, iSCSI, SMB or something) for a few days and then watch the magic happen. Lots of concurrent IO seems to trigger it more frequently. /K --=20 You are receiving this mail because: You are the assignee for the bug.=
