[Roveer]

I woke up to email messages saying: CRITICAL: June 13, 2018, 3:49 a.m. - The boot volume state is ONLINE: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected.

Nothing in the GUI tells me what's happening on which device.

I've got 8 2TB drives in a single ZFS2 array.

I've also got 2 16GB usb memory sticks (2 weeks old) as boot.

I'm assuming at this point it has something to do with those usb boot sticks. How do I find out exactly what's going on?

Thanks,

Roveer

I'll guess one of your USB sticks has accumulated write errors. Mine didn't last a month.

You can get more info from the UI via System->Boot (tab), followed by clicking the status button. If you're comfortable with ssh, ssh in to the CLI and run "zpool status".

I second @rvassar's conclusion and suggestions - an alternative to ssh is to use the Shell window, suggest you expand it to full size, and run "zpool status", examine the boot section.

Thanks for the info. I'll check when I get back to a computer. What's the best course? Just keep changing the offending stick still you no longer have the issue? Is this a problem? I remember reading a thread or two about dual usbs having failures. Or eventually I'll end up with two sticks that just don't cause problems?

Thanks.

If you do a search here you will find multiple reports of failing USB boot sticks. You'll also find strong support for them, too, from some of the most experienced people here. Based on my personal experience, an appropriate course is to switch to an SSD if you have an available SATA port. I have also run one system with an old SATA laptop HDD as @Chris Moore here frequently promotes - works just fine and the slower speed is no issue for (hopefully) infrequent bootups. I think that most of us who use SSD's for boot do not duplicate them - you can, but their reliability doesn't seem to justify the expense.

Not sure about best, but most reliable course is an SSD for your boot drive.

See my USB Boot thread in the "Will it FreeNAS" section. I'm moving away from USB boot devices. I'm waiting on a SAS HBA to arrive, then I'll use a small SSD to boot.

On edit: Also... Make sure you relocate your system dataset to the main pool. See the docs...

I've got 8 2TB drives in a single ZFS2 array.

I am guessing that you mean to say RAIDz2?

Everyone who responded. Thanks a bunch for all the good information. This afternoon I saved my FreeNAS configuration file (with passwords), pulled the 2 usb sticks threw in a 32GB SSD, changed my M1015 to allow it to boot, set the SSD to be the boot device, reinstalled freeNAS and uploaded my configuration file. and I'm back in Bidness booting from an SSD.

I also checked my system dataset and it's on DATA which is the main pool.

Couldn't have been easier.

Chris, Thanks for the tips. I'll take some time to read up on terminology so I don't sound like such an idiot when I come here for help. Must sound like fingernails on a chalkboard to you, but what can I say, I was kinda close. Hold on a second while I grab my drink off that cup holder on the front of PC.

So thanks for all those who posted. Lets see what happens next. Maybe nothing, which would be just fantastic.

Seriously, I just wanted to help.
I hope it is uneventful from here on.
