CRITICAL: The boot volume state is DEGRADED

[Myopia]

I'm using FreeNAS for some years again, but now I ran into some issues. I got a mail from my FreeNAS, with the following message:

CRITICAL: The boot volume state is DEGRADED: One or more devices has experienced an error resulting in data corruption. Applications may be affected.

status says:

Code:

What could be wrong? And what to do?

Your boot pool is degraded. If you stated your hardware as per the forum rules you could have got a more detailed reply.

What you need to do is get a new boot device, install FreeNAS and reload your configuration. If you have not saved a configuration, do so before scrapping this boot device.

So I just fresh install FreeNAS 11.1 and then restore the 11.0-U4 configuration file?

That would be a good first step. You can backup your config by going to the web UI > System > General > "Save Config". After you reinstall, you'll restore the config on that same page.

Do you have your OS installed on a USB flash drive? If so, you might as well get another flash drive and reinstall on that instead. Those drives don't last indefinitely, but thankfully they're cheap and easy to replace.

Thanks. I've ordered the SanDisk Cruzer Fit as recommended USB drive.

I've have succesfully installed a fresh version and updated the configuration file. Thumbs up for FreeNAS! It all went smoothly.

I got a few warnings:

• WARNING: July 16, 2018, 9:13 p.m. - smartd_daemon is not running.
• WARNING: July 16, 2018, 9:13 p.m. - New feature flags are available for volume archive. Refer to the "Upgrading a ZFS Pool" section of the User Guide for instructions.

Upgrading a ZFS pool, can this be done without any risk? And why would I do it?

WARNING: July 16, 2018, 9:13 p.m. - smartd_daemon is not running.

Make sure you disable SMART for your USB boot drive as thins can prevent it from starting.

WARNING: July 16, 2018, 9:13 p.m. - New feature flags are available for volume archive. Refer to the "Upgrading a ZFS Pool" section of the User Guide for instructions.

I try not to update things without reason. As this is not a security thing, I would just leave it unless you have a backup. Its a low risk thing but why take a chance. Feel free to read up on it and make your own call.

The features added are the sha512 and skein hash functions. These are only useful if you have dedupe enabled on the pool in question. If you aren't using dedupe, you can skip this upgrade and just uncheck the warning in the status box.

When new features are released, you can read about them on FreeBSD's zpool-features man page: https://www.freebsd.org/cgi/man.cgi?query=zpool-features&sektion=7&n=1

There's some cool stuff in the works, so don't be afraid to upgrade your pool when you want to try out new stuff. It's generally a very safe operation unless you have backwards compatibility requirements on the pool (i.e., you want to replicate the pool to a system running an older version of FreeNAS/BSD, etc.).

Thank you all for the great support! I'm very happy with my FreeNAS setup, which is running for 2,5 year. Sadly the SD card with the FreeNAS was degraged, but reinstallation and restoring configuration is very easy to do. Maybe in the future I will setup a new FreeNAS at a different location for data mirroring. :D
