Any news regarding this issue? I'm having the same problems. I'm using an external Axus SCSI enclosure (Yotta with 16 drives) and it timed out on scanning LUNs (16 of them b/c Yotta is configured as JBOD).
I've performed firmware upgrade to the Yotta system and now the scanning works, the pool build works, I'm even able to perform some transfers but after some time everything hangs, iostat shows 100% busy on drives and timeouts in dmesg. Still, if I keep the LUN number to <=8 everything works correctly. I think that eliminates the problems of cabling or any other hardware involved. All the problems start when using >8 LUNs (sd.conf is configured correctly, adpu320.conf is configured with maximum 16 LUNs). Linux kernel 2.6.18 had the same problems in the past, but current kernel works without any problem, so they've changed something in the driver which eliminated the issue. If any extra info is needed I'm ready to provide it. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
