"One or more devices has experienced an error resulting in data corruption. Applications may be affected."

So my SSD which is jail drive and also some important files which i edit off (Like Google Drive) and another drive with 2x2TB WD RED drives.

The question is how do fix this issue and remove the notification of this. Thanks

You don't "fix" this issue. This is your warning that you now have problems.

Please show us the COMPLETE output of
Code:
zpool status -v


We'll take a look and tell you which devices are faulted, then we will advise you on how to clear the error notification and how to proceed.

In addition, the rest of the information called for in the forum rules would be appropriate, particularly hardware specifics and FreeNAS version.

My system is kinda ghetto
Fx6300
2*4GB ECC unregistered memory (Tested through memtest working fine)
Asus M5A78L-M LX v2
2x2TB WD RED
240 GB OZR Trion SSD
VS500 WATTS PSU

Version :

FreeNAS-9.10-STABLE-201604261518 (881b70d)


I don't think my specs and version really effect my problem.

There's corrupted metadata in the SSD_HomeNas dataset on your SSD pool. Since you have no redundancy on that pool, there's no way for ZFS to fix it. Since you've never run a scrub on that pool, it's possible there's other data corruption that hasn't been detected yet. With metadata corruption, the only real remedy is to destroy the pool and restore from backup.

They may not but they do affect the answers you get in relation to your problem.

So after i deleted that dataset i still get the error:

That looks like corruption in metadata. The only way to recover is to delete the pool and recreate it on a working drive or, better, with some redundancy (mirror, RAID-Zx, ...).
