UPS shutdown command power off or halt

[alexg]

I realize that this may not be FreeNAS specific question, but I'm wondering how you guys setup your NAS to run 24x7. BIOS supports AC Power Restore mode of "Last State". I see that FreeNAS sets up SHUTDOWN command in upsmon.conf as "/sbin/shutdown -p now". This means that when UPS forces the shutdown, it will power off the system and it will not come back up when power is restored.

Should I change this to "-h" (halt) instead of "-p"? What is the general opinion on this.

Thanks

No, you're totally confused.

-p is all that you want for that. If you don't do a -p and choose for -h the box will halt. That is, the OS will turn off completely, but the box will still be powered on. That's not good when you are on the UPS.

On a loss of power, when you are on the UPS you absolutely want the box to power off. That's what it's *supposed* to do because you have no reliable power source. When power is restored you'll have to power-on the UPS manually(most likely), and you can turn the computer on then. But, reguardless of what choices you make, if the UPS goes dead, you *will* have to touch the UPS to turn it back on.

I'm not a fan of the computer ever powering on when power is restored. I want to power it on when I'm ready for it. Even if I'm doing it over IPMI. You can make your own choice for your situation. It is your server and your data lost if you make a bad choice. ;)

Thanks for advice. Just need to teach my spouse which machine to power on in my basement lab when I'm not home.

I did a test, unplugged the power cable, after 900s freenas initiated poweroff and went down but I have one problem:

- In freenas UPS service menu I have selected "Power Off UPS" but it doesn't work, UPS stay online after NAS box is down...

I have tested command "upsdrvctl shutdown" and it works:

[root@freenas] ~# upsdrvctl shutdown
Network UPS Tools - UPS driver controller 2.7.3
Network UPS Tools - Generic HID driver 0.39 (2.7.3)
USB communication driver 0.32
Using subdriver: MGE HID 1.38
Initiating UPS shutdown

I want shutdown UPS together with NAS box and AFTER electricity is restored UPS should start and power on the NAS box (in BIOS is set to power ON after electricity is ON)

This is a major feature because without it NAS box never start automatically when electricity is back online!

Thank you.
