Permanent Errors have been detected

[Aschtra]

Hi everyone,

I am a fairly new FreeNAS user and I currently have a red critical button blinking saying the following:

"The volume MediaVolume state is ONLINE: One or more devices has experienced an error resulting in data corruption. Applications may be affected."

This message came up after a reboot of the system.
I googled this error and tried the following command: zpool status -v

So it appears I have 4 files which are bad.
However, this seems like system files which FreeNAS uses?

Can someone help me to fix the errors?

I have the following setup:

HP Microserver Gen8 4GB RAM, standard CPU
16GB USB on which FreeNAS is installed
128GB SSD which hosts the Jails
4x2TB in Raid5 which has all my media.

Thank you in advance! I don't really know what information to provide more so if you need anything just ask!

edit:

The thing I did before the reboot was installed a new Jail with Radarr with this guideL
https://www.reddit.com/r/radarr/comments/5qht69/guide_on_how_to_install_radarr_as_a_servicedaemon/

after that I rebooted the FreeNAS server and saw this error.
I also updated my FreeNAS after the first reboot to version 11 U4.

2nd edit:

I just deleted the new Jail in which I installed Radarr but it didn't solve the errors. So the new Jail isn't the culprit atleast :p

Your zpool status output only shows a single disk. Is this a hardware RAID5 array? If so, very bad idea.

Yes my HP Microserver has a HP P212 Raid controller in which I configured the Raid5.

Also, where can I find these files that are giving errors? I don't recognize them.

This is most likely why you have a data fault.

Luckily, only info you have lost at this stage is from system dataset, Ie, nothing critical. But you could lose the lot at any moment.

To fix this you should backup your media, directly connect the disks to the motherboard (forget about the raid controller). Recreate the volume on the disks, then restore data.

Start over, and read the manual first.

And make sure you meet the minimum system requirements when you do. 4GB of RAM isn't going to cut it. 8GB is the minimum and you'll want more if you plan on running jails.

Thank you for your reply. I have about 4.3TB of data in use. I can backup this to other devices.
I understand now that the preferred way of making volumes in FreeNAS is not by using a hardware raid. But using the Software Raid which FreeNAS provides. If I understand correctly I can still make a Raid5 like setup with 1 drive being able to fail out of 4.

I will! Do you maybe have the link for it?

It's on the to-do list :) I am currently running 4 jails. SABNzbd, Plex, Sonarr and Radarr
