Hi all,
I run a OmniOS v11 r151012 + napp-it pro v. 0.9f4 system that spontaneously reboots during scrubs. Setup is:
Supermicro Chassis 847E16-R1K28LPB (36x3.5" HDD)
Supermicro Board X9SRL-F, 64GB RAM
LSI 9207-8i
The chassis has 2 expanders: SAS2X36 + SAS2X28 (controller connects only to SAS2X36)
Currently there are 8 SAS and 11 SATA drives in the chassis. I have 2 ZFS pools (besides the root pool that is on 2 USB Sticks). The first pool is made up from the SATA drives the other is made up from SAS drives.
The server rebooted twice during the last scrub of the SATA pool. Sometimes I see messages like:
I see these messages not only for target 13 but for all (more or less) disks in the system (SATA and SAS disks).
Is this related to the fact that there are SATA and SAS disks behind the expander? Or is this more likely a HW issue with the controller or expander(s)? Up until now I have seen these warnings/reboots only during scrubs.
I have to admit that I am not a Solaris/OmniOS expert and my knowledge on ZFS is limited. If there is anything I could debug please tell me how to
Thanx and Regards
