How to clear security alert

[blubberor]

Hi,
I am using Freenas 11 on my NAS with 8GB RAM, FreeNAS installed to a SSD drive and everything installed on a ASRock N3150-ITX.

From Timemachine hickups of my Mac, the backup got some problems:

Code:

hecking status of zfs pools:
NAME		   SIZE  ALLOC   FREE  EXPANDSZ   FRAG	CAP  DEDUP  HEALTH  ALTROOT
NAS		   5.44T  1.66T  3.78T		 -	13%	30%  1.00x  ONLINE  /mnt
freenas-boot   111G  7.66G   103G		 -	  -	 6%  1.00x  ONLINE  -

  pool: NAS
state: ONLINE
status: One or more devices has experienced an error resulting in data
	corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
	entire pool from backup.

Local system status:

-- End of daily output --

But though I completey recreatetd the data set, the alert stays the same.
Is there a way how to reset the alerts?

Thanks already in advance.

Do a zpool status -v

It will list the file that has an error. Assuming, it's a file you recognize, at a minimum, delete it.

If it's not something you recognize, post the result here.

You have corruption in your metadata.

The only way to fix this is to back up your volume, destroy your pool, rebuild it and restore your data.

Sorry to be the bearer of bad news.

initially I had the errors sitting in my timemachine, any other way to fix this, or only possible if I recreate the whole pool?
any good idea how I should create this? stop the NAS, copy all data to one drive and kill the 2nd pool or how would you proceed practically?
thanks and best,

[gpsguy]

Hopefully someone else can give you some direction today. I'll probably be busy for the next several hours.

 

[blubberor]

I did not find any other good solution but shouldn't it be possible to recreate the meta data?

 

[gpsguy]

Yes.

Unfortunately not.

but shouldn't it be possible to recreate the meta data?

 

[blubberor]

Yes.



Unfortunately not.

excuse me to bother again.
could you just point out the steps a bit more. I was thinking if I could stop the NAS so I would see two drives. Keep Drive 1 running as is, format drive 2, copy all data to drive 2, format drive 1, fuse both drives again as a NAS and replication should restore all data to drive 1. hope this makes sense. is this possible?

 

[gpsguy]

I am swamped right now. I will ping a couple other guys. @Stux @danb35 can you help the OP out

 

[Stux]

Time Machine hiccups can't cause this.

Lack of ECC can.

Have you got ECC Ram?

Backup the data (Ie via smb/AFP) or rsync

Delete the pool. Recreate pool. Restore data.
