help! i cant see pools

[jinks_one]

Hi,

I am an extreme Newbie. I followed youtube tutes to set up and install my FREENAS system.

Basically it looks as if a couple of my hard drives have failed and have too many bad sectors, namely ada1 and ada2. So i thought i would just replace the drives with new ones.

The PROBLEM: In all of the instructions and youtube tutes the procedure seems to be:
GOTO storage>POOLS... (and then a whole bunch of more steps to take disk offline, replace and then resilver etc).
HOWEVER, this is where im stopped in my tracks... there is no pools in the tree?

i have included screenshots of the critical errors and of the UI which isnt showing me the pools option. If anyone can help direct me, or spot where i am going wrong?

Sadly you failed to specify which version you have. If it's not the case update to the latest version. Hope that helps.
BTW, your hardware does not meet the usual requirements for FreeNAS. Read the forums about it.

Hi @jinks_one, sorry to hear you're having problems.

I know there are some great videos on youtube. I recommend you go to the User Guide here first when you have issues, just because you know the User Guide is quality advice but some youtube videos may be not so great.

Do you happen to know what your pool layout was? Were you using encryption at all? You have two faulty drives, ada1 and da2?

What do you get from the command line when you type zpool status?

im so sorry @hervon :version FreeNAS-11.1-U7 @PhiloEpisteme i dont think i was using encryption but heres a screen shot of the zpool status from cmd

Hey jinks,

Was your pool configured as Raid-Z1 ? If it was and two drives failed at once, then indeed your pool is probably lost. A Raid-Z1 structure can loose only 1 drive, not 2...

This is also why you should always have backups. No single server, even FreeNAS, can ensure never to suffer any problem and never loose any data. All servers can be damaged by fire, just like human error can happen anywhere.

If you loss 2 drives in a Raid-Z1 structure and you have your backups, maybe it will be easier to just build a new pool and restore your backups...

Repairing a damaged pool is challenging, I have recently successfully recovered most of a pool for a friend who had a pool "vanish"

ZFS is really really good at protecting data on the right hardware, pool design, with the correct administration

ZFS will even list damaged files

If you pool is unencrypted you have a chance

Everything below is done at your own risk

Firstly I would unplug all the data drives and your boot drives

Install freeNAS on a clean SSD from a USB ISO

Turn the server on to see if it boots correctly if it does power down the server

Reconnect your data pool drives

Turn on the server, attach the pool, then add a share from the GUI (I use FreeNAS-11.0-U2 so cannot help with this process)

Copy the data to a location not in this pool ie another computer

Run a scrub (this should take hours not days)

From shell or SSH client if you can (turn on this service)

Code:

zpool status -v

It will display the path and file name of every corrupted file, these are unusable

Plug in anothe drive the same size as the damaged drive, then replace it from the GUI, this should take hours not days

Lastly please read the hardware recommend resource, setup automated smart tests, scrubs, temperature monitoring, and setup Emails. If you do the problem you have had go away, your data will be secure

Hope this helps

Let me know how you get on

Have Fun
