I have two identical Supermicro boxes with 32GB ram. Hardware details at
the end of the message.
They were running OI 151.a.5 for months. The zpool configuration was one
storage zpool with 3 vdevs of 8 disks in RAIDZ2.
The OI installation is absolutely clean. Just next-next-next until done.
All I do is configure the network after install. I don't install or enable
any other services.
Then I added more disks and rebuild the systems with OI 151.a.7 and this
time configured the zpool with 6 vdevs of 5 disks in RAIDZ.
The systems started crashing really bad. They just disappear from the
network, black and unresponsive console, no error lights but no activity
indication either. The only way out is to power cycle the system.
There is no pattern in the crashes. It may crash in 2 days in may crash in
I upgraded the memory on both systems to 128GB at no avail. This is the max
memory they can take.
In summary all I did is upgrade to OI 151.a.7 and reconfigured zpool.
Any idea what could be the problem.
