GEOM: ada0: the primary GPT table is corrupt or invalid

[eichof]

Hello togehter
I get this email message from my freenas installation:

freenas.local kernel log messages:
> GEOM: ada0: the primary GPT table is corrupt or invalid.
> GEOM: ada0: using the secondary instead -- recovery strongly advised.

-- End of security output --

What does this mean? Do I have to worry about it?
Freenas is still running and doesn't show any alerts.

Thank you!

GEOM? So we're dealing with UFS?

Hardware and details please.

And see the section "RECOVERING".

No, I have ZFS.

Hardware:
16 GB Ram
Intel G3258 @3Ghz
3 x 3TB WD Red
AsRock H97-M-ITX

I've read the recovering section, but does the system heal it self?

 

[BigDave]

Do you have you data backed up?
Which version of FreeNAS are u running?
How is your pool configured, Raidz, RAIDz1 ???
Please post (in CODE tags), the output of #zpool status
Thnx!

Yes, it should restore the backup GPT*:

Code:

gpart recover /dev/ada0

EDIT: *Assuming your disk is not bad. If your disk is bad, all bets are off.

1. The critical data has a backup
2. Freenas Version is: FreeNAS-9.3-STABLE-201509022158
3. It's a raidz

Please post output within CODE tags [ ]
Suggest you run a long smart tests on your drives and post the results.
Your output shows RAIDz1, which suggests a mirror configuration

3 x 3TB WD Red

I'm wondering where the third drive is in that output?

Code:

IT
SHOULD
LOOK
LIKE
THIS

 

[eichof]

The third drives id is "ada0".
That drive showed me a lot of chksum errors, I pulled it out and ran a long smart test without any errors. But after a new installation of that drive it didn't recognized the drive, so I had to install it manualy with some code samples on the internet, that's why it has no "gptid" just named it ada0.

No, RAIDZ1 is not a mirror--you're thinking of RAID1. The third drive is ada0, indicating that a drive has been replaced incorrectly from the CLI.

 

[eichof]

It should be a raid5

 

[danb35]

There's no need to pull drives to run SMART tests on them. In fact, you should configure your server to run them automatically on a schedule.

 

[Ericloewe]

But after a new installation of that drive it didn't recognized the drive, so I had to install it manualy with some code samples on the internet

That is never a good idea.

 

[cyberjock]

The reason for the error is someone used the CLI instead of the WebGUI to replace the disk. ada0 has no partition, so the error is expected. Remove ada0 from the zpool, and re-add it *properly* using the WebGUI and the problem will go away.
