--- Comment #31 from karli.sjob...@slu.se --- (In reply to Stephen McConnell from comment #30) OK, yeah we´re on the same page. The drive doesn´t show up but therein 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´t really make it happen at will, but it has happened quite frequently as of late. What 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´s the least amount of drives where I´ve 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 -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
