Narrow escape with FAULTED disks
Nothing like a "heart in mouth moment" to shave tears from your life.
I rebooted a snv_132 box in perfect heath, and it came back up with two FAULTED disks in the same vdisk group.
Everything an hour on Google I found basically said "your data is gone".
All 45Tb of it.
A postmortem of fmadm showed a single disk failed with smart predictive failure.
No indication why the

ZFS storage server hardware
...in the future and decide to add more drives on each controller I think
option 3 is the best way to go. I can have a motherboard with a lot of
PCIe slots and have one controller card for each expander.
Cases like the Supermicro 846E1-R900B have 24 hot swap bays accessible
via a single (4u) LSI SASX36 SAS expander chip, but I''m worried about
controller death and having the backplane as a single point of failure.
I guess, ideally, I''d like a 4u enclosure with 2x2u SAS expanders. If I
wanted hardware redundancy, I could then use mirrored vdevs with one
side of each mirror on...

Seriously degraded SAS multipathing performance
...chieve full throughput
across both paths.
My System Config:
OpenSolaris snv_134
2 x E5520 2.4 GHz Xeon Quad-Core Processors
48 GB RAM
2 x LSI SAS 9200-8e (eight-port external 6Gb/s SATA and SAS PCIe 2.0 HBA)
1 X Mellanox 40 Gb/s dual port card PCIe 2.0
1 x JBOD: Supermicro SC846E2-R900B (Dual LSI SASX36 3Gb/s Expander
Backplane, 24 Hot Swap drives)
22 x Seagate Constellation ES SAS drives
Performance I''m seeing with Multipathing Enabled (driver: mpt_sas):
With only one of the two paths connected:
1 drive connected: 137 MB/s sustained write, asvc_t: 8 ms
22 drives connected: 1.1 GB/s su...

Disk failure chokes all the disks attached to the failing disk HBA
Dear All,
It may be this not the correct mailing list, but I''m having a ZFS issue
when a disk is failing.
The system is a supermicro motherboard X8DTH-6F in a 4U chassis
(SC847E1-R1400LPB) and an external SAS2 JBOD (SC847E16-RJBOD1).
It makes a system with a total of 4 backplanes (2x SAS + 2x SAS2) each
of them connected to a 4 different HBA (2x LSI 3081E-R (1068 chip) + 2x
LSI
