Critical ZFS error after update

[KEvinn]

Hi,

After updating my Freenass yesterday to the latest firmware i have received a critical error saying the following:

CRITICAL: The volume HDD320GB (ZFS) state is ONLINE: One or more devices has experienced an error resulting in data corruption. Applications may be affected.

Im not sure how to fix this error. I ran this command (zpool status -v | more ) to see if it would give me more info but i have no clue what the permanent damaged files are and if this is something i should worry about. The command came up with the following info:

Code:

[root@freenas ~]# zpool status -v | more

The files <metadata>:<0x220> & <metadata>:<0xec> are permanent damaged but as
I said i have no idea what these files are so if anyone can help me would be greatly appreciated.

Kind Regards,
Kevin

Please post your hardware manifest. On a properly designed FreeNAS system with ECC and redundancy, this isn't supposed to happen, but it looks like you don't have any redundancy in your storage, which suggests maybe you have other hardware deficiencies as well.

 

[SweetAndLow]

Using a striped pool so you don't have redundancy and any little bit of data corruption can't be fixed.

Most metadata's supposed to be redundant regardless through the storage of a second copy.

It is an old gaming computer so i don't think its a perfect setup for Freenass. Also had 1 working HDD of 320GB so I configured it with RAID-0 if im not mistaken. After a few months when it was full i just bought extra HDDs and filled the array up. I was to lazy to wipe the diks and configure it in RAID 1 or 2, Its a 1,5 TB RAID 0 Plex streaming and Torrents seeding box now. Here are the specs:

[jgreco]

Yeah, you lack both ECC and redundancy, so pool errors are not ... unexpected.

 

[KEvinn]

So, should I be worried with this error or ? Because is till have no idea what is corrupted.

 

[jgreco]

We don't know what's corrupted either, just that it's pool metadata. ZFS advises:

action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

Which seems to be correct. ZFS does not have tools to repair the pool, so making sure corruption does not enter the pool is important.
