Follow on to the question(s) I asked the other night about disk weirdness.

I found some folks having problems with Seagate Exos drives (in very unsimilar environments, so NaCl) where disabling the EPC stuff seemed to help.

Does that remind anyone of anything in smartos land with C620 chipset sata ports?

after finding a reddit thread about seagate epc controls - I wonder whether the problem could be related to increased power usage when spinning up when leaving a low-power state.

particularly if you have a multi-disk mirror or raidz set where N disks all want to leave idle at the same time.

For example. There's also the time needed to return from some of the idle conditions, anywhere from half a second to 8 or more seconds.

pjustice: You mean the HW-RAID ones... yeah that's probably not going to happen. :(

you might be able to use the sg3 utils to disable EPC and see if that helps any

though i don't think pkgsrc builds them currently...

No hardware RAID involved.

I do have a way to disable EPC elsewhere, though at this point I've replaced the Exos drives with SSDs.

I'm trying to get Seagate's openSeaChest stuff to build, they have a subtree where they define offset_t that's easy to fix, and a va_list issue somehow.

Is it possible using the triton command-line tools to configure the anti-spoofing options? I'm setting up some IPv6 services and need to flip the "Allow IP spoofing" bit for instances that provide those services.

I'd prefer to not have to jump into AdminUI everytime I create an instance, but it's not a tremendous burden if that's the only way.

jdt: No, but there is a plugin that can do it: github.com/TritonDataCenter/triton-…master/plugins/allow_ip_spoofing.js
