Is my disk encrypted? Corrupt GPT table.

[qxw]

Dear all,
I have built a FreeNAS from an HP N54L Micro server with five disks. RAIDZ initially I have created from 4 x 640GB + 1 x 320GB WD drives. My data were stored on 1TB WD drive in PC. After copying data from 1 TB drive to RAIDZ I have replaced 320GB disk with 1TB disk. It was not easy, but reading this forum and some googleing helped and finally I have everything successfully solved.
But...
...there are some worrying moments...

Despite having done nothing connected with encryption, these rows are in my dmesg:

Code:

ZFS filesystem version: 5 
ZFS storage pool version: features support (5000) 
GEOM_ELI: Device ada4p1.eli created. 
GEOM_ELI: Encryption: AES-XTS 128 
GEOM_ELI: Crypto: software

Now I do not dare reboot the system, I am afraid that I have somehow encrypted the disk and after rebooting I will not be able to read from it!
Cold you please tell me how can I make out whether this disk is encrypted or not?

Some another ugly rows:

Code:

GEOM: ada1: the primary GPT table is corrupt or invalid. 
GEOM: ada1: using the secondary instead -- recovery strongly advised. 
GEOM: ada2: the primary GPT table is corrupt or invalid. 
GEOM: ada2: using the secondary instead -- recovery strongly advised. 
GEOM: ada3: the primary GPT table is corrupt or invalid. 
GEOM: ada3: using the secondary instead -- recovery strongly advised.

I tried follow the strong advice, but it did not work:

Code:

[root@freenas /var/log]# gpart recover /dev/ada1 
gpart: arg0 'ada1': Invalid argument

What am I doing wrong?

Thanks for the answer in advance.

Only the swap partitions are encrypted - not your data partitions. Check the output of gpart show - the first partition on each disk should be of type freebsd-swap.
I can't help you with the gpart recover, the syntax looks ok.

Code:

[root@freenas ~]# gpart show

Do you see here, what should be seen? :)

 

[warri]

Yes, ada4p1 is a swap partition and ada4p2 your zfs partition :)

But I'm wondering where your other disks are in the list. ada1, ada2 and ada3 should have the same configuration as ada4. What's the output of zpool status?

 

[cyberjock]

I'm thinking that the gpart show tripped up.. I'm fairly sure this line is where the program had some kind of error...

16 1930241 1 !0 (942M)

Yep, a quick way to check if something is encrypted is in the storage interface in the GUI. If the zpool is encrypted there will be sepcial encrytpion related buttons at the bottom if you select the pool in question.

The output in your specific paste though does simply appear to just be the swap partition as was previously mentioned by the other poster.

Your disks were NOT created on FreeNAS from the GUI. You are using FreeNAS outside of its design. Here's why I say this:

1. FreeNAS creates a GPT partition table(you don't have this)
2. FreeNAS defaults to a 2GB swap partition on every disk(you don't have this either)
3. FreeNAS then creates a partition that is the size of the remaining space on your disk(you don't have this either).

In short, you are using FreeNAS outside of its design characteristics. My first guess is whomever created your zpool didn't use FreeNAS' GUI or all 3 things above would exist.

 

[cyberjock]

Oh.. Forgot to add that nothing appears wrong except for the wrongly created pool. You should consider backing up your pool, destroying your pool and recreating it properly using the instructions in the FreeNAS manual.

Isn't line 15 in his copy-paste the 2G swap?

The one that says:

1. 128 4194304 1 freebsd-swap (2.0G)
   
   
   Or am I missing something fundamental there?

That's only for ada4.. and that one disk is part of the pool.. see the GPTID under his zpool status. Likely he added a disk after the fact(ug.. bad idea) or he did a disk replacement. Since he posted the output without putting it in CODE the formatting of the text is lost so we don't know which one he did.

 

[qxw]

Cybejock, you are right! :)
I have not been able to create it in GUI, because one of my disks has different size. So experimented with CLI.
Now I am seeing the experiment was not 100% successful.
I will try to write exactly how I created the zpool. Will you please find the mistakes I have done and correct them?

Yes, I replaced the disk from 4 x 640GB + 1 x 320GB RAIDZ to 4 x 640GB + 1 x 1 TB
Is it possible to replace it back, shrink the pool? I will need storage room for backup, if I recreate the pool.

 

[cyberjock]

The only way to correct them is to destroy your pool. You could try removing each disk from the pool and readding it, but since you went with RAIDZ1 that's VERY dangerous. One error on any of the rebuilds could spell problems.

 

[cyberjock]

You cannot shrink a pool. :(

 

[warri]

I fully agree with cyberjock.

There are some topics about properly creating a pool from CLI. You need to create gpt labels, add a swap partition and zfs partition and use the gpt labels to create the pool. The easiest and recommended way is to follow the instructions in the manual and to use the GUI for this task, though.

He has different sized disks so the 9.2.0 GUI won't work. He either has to use 8.3.2 to create the pool or wait for 9.2.1 that will allow you to use the "legacy" volume manager again (now called "Manual Setup" :)).

 

[warri]

I didn't follow the bug tracker too closely in the last week, good to hear that this will finally be possible again in 9.2.1!

I just deleted all partition and converted to GPT disk each disk in Windows PC.
I put disks to FreeNAS box and created pool:
zpool create -f -m /mnt/tar tar raidz ada0 ada1 ada2 ada3 ada4
zpool export tar
After it I did Auto import from GUI.
Now I understand what is missing, but I do not have the exact algorithm. Could you advise me where can I find a good guide for this whole process?

Do you mean each disk one by one goes offline (degrade array) correct gpt label, swap etc. and resilver?
