I suspect memory errors on my Sol 10 u8 system, but there are no memory errors
reported by "fmdump -eV". All the errors and events are zfs related.
Initial symptom is starting a scrub on a freshly booted system will complete
properly, but the same operation after the system has been up for a few days
will cause a kernel panic. Immediately after a reboot a scrub will complete
normally. This behavior suggests bit fade to me.
This has been very consistent for the last few months. The system is an HP
Z400 which is 10 years old and generally has run 24x7. It was certified by Sun
for Solaris 10 which is why I bought it and uses unbuffered, unregistered ECC
DDR3 DIMMs. Since my initial purchase I have bought three more Z400s.
Recently the system became unstable to the point I have not been able to
complete a "zfs send -R" to a 12 TB WD USB drive. My last attempt using a
Hipster LiveImage died after ~25 hours.
My Hipster 2017.10 system shows some events which appear to be ECC related, but
I'm not able to interpret them. I've attached a file with the last such event.
Not sure that will work, but worth trying. This is from my regular internet
access host. So it is up 24x7 with few exceptions.
Except for the CPU and memory, the machines are almost identical. The Hipster
machine is an older 4 DIMM slot machine with the same 3 way mirror on s0 and 3
disk RAIDZ1 on s1. The Sol 10 system is a 6 DIMM slot model and has a 3 TB
mirrored scratch pool in addition to the s0 & s1 root and export pools.
It seems unlikely that I could simply swap the disks between the two, but I can
install Hipster on a single drive for rpool and attempt to copy the scratch
pool, spool, with that and simply run it for a while for testing.
I've read everything I can find about the Fault Manager, but it has produced
more questions than answers.
This is for Hipster 2017.10:

It's a little longer than for Sol 10 u8, but the cpumem-retire V 1.1 appears on
both.
Suggestions?
