You are right, I've done a lot of tests and the defect is narrorw down the "problem hardware". The two pool works fine in one chassis but after moved to original enclosure, it just failed when CP or ZFS send. I also noticed when the machine bootup reading ZFS configure, there is a warning message. " REading ZFS config:" *Warning" /p...@0,0/pci8086,3...@8/pci15d9,1...@0(mpt0): Discovery in progress, can't verify IO unit config. I did search a lot but cannot find more details. my 2 server configuration: 1. "PRoblem chassis" supermicro SuperChassis847e2. Tysonberg MB with onboard LSI 1068e (IT mode, which direct expose HD to system without RAID), Single Xeon5520. 2. "Good Chassis":Self-developed chassis by other department. S5000WB MB, single E5504, 2 PCIe-4x LSI 3081 HBA card. Seems the SAS cable are all connecting right. I suspect the issue of onboard 1068e and moving the LSI3081 card to the "problem" server to test. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
