Hi,
1)
http://www.openbsd.org/papers/asiabsdcon2010_softraid/softraid.pdf page
3 "2.2 RAID 1" says that it reads "on a round-robin basis from all
active chunks", i.e. read operations are spread evenly across disks.
Since then did anyone implement selective reading based on experienced
read operation time, or a user-specified device read priority order?
That would allow Softraid RAID1 based on 1 SSD mirror + 1 SSD mirror + 1
HDD mirror, which would give the best combination of IO performance and
data security OpenBSD would offer today.
2)
Also if there's a read/write failure (or excessive time consumption for
a single operation, say 15 seconds), will Softraid RAID1 learn to take
the broken disk out of use?
Thanks,
Tinker
