I've got everything almost setup, but was wanting to check I was doing the basic things like shutting down/re-booting my nas properly.

 

1) using ap to shutdown nas

I installed apc after it recommended, i dont have a ups but the /sbin/powerdown command was really easy to use. So just to confirm, I dont need to stop the array, just run the command and thats it? Here is the output:

2) Rebooting

If the above command is ok, is there a reboot equivalent?

 

Thanks

sorry to bump my own post, just worried that i might be corrupting my data if Im not using apc correctly

If you don't have a UPS how do you think apcupsd is going to benefit you?

Is there a chance I have done any damage to my data? I was under the impression that the acp plugin shutdown the server better than the web interface (it saved me trying to get figure out how to get those shutdown scripts installed).

The powerdown script (which is what the apcupsd plugin uses) is available as a stand-alone package within unmenu.

You've been misinformed. There is no reason not to shut down or reboot from the web gui other than you can't access the web gui. Install the powerdown script and you will then be able to shutdown or reboot the array from the terminal.

 

If you're worry about your data having been corrupted run a parity check.

Perhaps not misinformed ... the powerdown script has a very distinct advantage over the web gui- it will do its best to stop active processes which can prevent the web gui stop/shutdown from completing.

lsof | grep "/mnt/user"

 

Majority of the time that lists stuff that's screwing up, then, from there you can work out what you need to end.

 

I do concur that typing "powerdown" is a lot easier than finding & ending processes, however.

@ Auto

Thanks for the command, I have a txt file with a bunch of handy tips...always good to find out another.

 

@ mrow

Cool, cheers for the tip...I never knew I could do that haha!

 

 

Another user helped me find out what was holding up my array from shutting down, turned out to be sab log files on my cache drive. Weird. But after reading your posts, i now think I misread the other guys post (which sunk in after reading peterb's comment haha)

 

/sbin/powerdown always works for me but you may have to install it. You can install it from unMenu and I think it is included in apcupsd plugin.

 

I was just setting up my nas box at the time and was already installing plugins so I zoned in on the apc plugin for some reason. I know realise unMenu would have been a better choice. How do i go about removing/uninstalling apc if I can get unMenu working on 5.0-rc12a?

You should really learn what they do, then you'd:-

A. Be able to memorize them easily

B. Be able to modify them for what you require.
