Errors mounting/unmounting hard disk

[hendrik.h]

Hey guys,
I need help to figure out what's wrong with my Freenas.
Today I received my new hard disk - 3TB WD30EFRX Red -, installed it in my Freenas Server (just updated to FreeNAS-8.3.1-RELEASE-p2-x64) and mounted it successfully (UFS). So far, so good.
I do not have any RAID configured, just 4 UFS-formatted hard disks.

Now the troubles began: As I was used to mount new disks with specified paths, I wanted to do the same with my new hard disk.
So I had to change the mounting path of that disk (in this case ada1).
Using the GUI, I first detached the disk succesfully, but as I tried to mount it again (this time with the right path), the console threw out this error:

[MiddlewareError: Unable to GPT format the disk "ada1"]

Tried this about 2-3 times, same error. On the 4th try, the GUI told me it had successfully mounted the disk, but looking into the "Storage"-Tab it had the same Used/Available/Size-statistics as the 3TB disk I already had in use before I installed the new one. Only difference: "Status" shows "DEGRADED".
Looking around in the forum, I only found that this status mostly occured in ZFS or RAID builds.

Now trying to detach the disk gives me back this error:

freenas manage.py: [middleware.exceptions:38] [MiddlewareError: Failed to detach storage2 with "umount /mnt/storage2" (exited with 1): umount: /mnt/storage2: statfs: No such file or directory umount: /mnt/storage2: unknown file system ]

Honestly I have no idea what is going on. I already ran a SMART-test (short) with no errors, so hopefully the hard drive isn't the problem.
Maybe someone who can help me? Thanks in advance

Did you "detach" the old drive from the GUI before installing the new drive?

Have you tried a reboot?

Can you post your hardware specs please?

I think i described it a little confusing. I don't want to replace any hard drive, just add the new one.
I already tried rebooting several times, problem persists.

Hardware:
AMD E-350 Processor (Asus E35M1-M Pro)
4 GB RAM (Kingston 1333MHz, DDR3)
1x WD Green 1TB
1x WD Green 1,5TB
1x WD Green 3TB

Unfortunately I'm even more confused now. Your hardware seems sufficient for the task. You said in the first post "it had the same Used/Available/Size-statistics as the 3TB disk I already had in use before I installed the new one" so I'm pretty confused now.

 

[hendrik.h]

Sorry for confusing you :D

I'll try to describe it clearer: One 3TB drive is already installed, a new 3TB was installed to expand the storage space.
Now looking in the "Storage"-Tab, the old 3TB (storage1) shows up normal, with "2.4TB Used - 95.9GB Available". Further down the list is the new 3TB drive (storage2), with the same statistics as the "storage1". Only it has the status "DEGRADED.

Hope it didn't make your confusion worse.

EDIT: Here's a screenshot to help you understand :)

I would try unmounting all of the disks from the GUI. Reboot, then remount them all. Naturally, you might get the error you mentioned above, but its the first thing I'd try.

Secondly, you could try running a long SMART test on the new drive to see if it has problems. Generally long tests are kind of pointless, but its better than nothing since you are already having problems.

 

[hendrik.h]

Wouldn't unmounting all drives result in data loss? Can I remount them without problems?

I'll give it a try and keep you up to date.
Thanks for the advice!

 

[cyberjock]

You should be able to unmount and remount them without problems. The system should be unmounting and remounting them every time it boots up and shuts down. If you lose data because of the unmount and remount you have bigger problems that would have eventually shown themselves on a reboot anyway. :P

 

[hendrik.h]

Okay, so unmounting the 1TB and 1,5TB was successful, unfortunately trying to unmount the older 3TB drive failed with this error:

May 4 16:09:37 freenas kernel: GEOM_ELI: Detached ada2p1.eli on last close.
May 4 16:09:37 freenas notifier: geli: No such device: /dev/ada2p1.
May 4 16:09:38 freenas manage.py: [middleware.exceptions:38] [MiddlewareError: Failed to remove mountpoint /mnt/storage1: [Errno 66] Directory not empty: '/mnt/storage1']

Now it shows me the following information about the disks

 

[cyberjock]

Yeah, those weird values can be ignored. Its a problem that creeps up with FreeNAS' GUI. Don't let it freak you out.

Can you post the output of:

# camcontrol devlist
# gpart list

Please put them inside of code tags so they are legible.

 

[hendrik.h]

Oh, ok. I'm currently wiping the hard drive with dd, as it seems that the partition table is corrupted.
I already tried those commands in the beginning, but can't exactly remember the output. It seemed normal to me, no errors.

I will post the output as soon as it finishes.

 

[hendrik.h]

By the way, before wiping the disk i ran

Code:

fsck_ufs ada1

and it gave me this:

Code:

** /dev/ada1                                                                    
Cannot find file system superblock                                              
ioctl (GCINFO): Inappropriate ioctl for device                                  
fsck_ufs: /dev/ada1: can't read disk label    

Does this mean the GPT is corrupted?

EDIT: Here are the command outputs you asked me for

Code:

Somehow the new disk (ada1) doesn't even show up here.

First, you shouldn't run a fsck command with the drive mounted. You can lose your data. In your case, I assume you have a backup since you just zeroed the disk.

Second, once you decided to do the disk wipe, the purpose of the gpart list was made mute. gpart list would have told me if your partition table was corrupt(it may have been repairable). Now that it has no partition table, it doesn't showup when you run gpart list. After you create a partition you should be able to run a gpart list and see it.

At this point, since the drive is zeroed out, I'd do a reboot, make sure the GUI looks correct. No drives that aren't mounted that should be, etc. Then go ahead and create your partition again in the GUI. That should fix everything.

I would have been happy if the disk would be mounted :D

I don't need a backup of an empty disk. I only zeroed it to delete the partition table.

After doing a reboot and attaching the disk with Volume Manager, the problem persists.

I am beginning to think that this has something to do with the specified path I am trying to mount it on, as the mount point is a folder on another disk.
Could that be it?

Oops. Duh! I knew that.. I was confusing you with another thread of someone having problems mounting.

I don't know. The way mounting works it shouldn't matter. It's different from Windows because you don't have the stupid Windows limitations.

It sounds to me almost like there is a discontinuity between the FreeNAS configuration and your actual configuration. But I don't know how to prove that is the problem, nor how to fix it except to reset your config to defaults and start over. Your data would be safe, but that's still a PITA. Things get really messy when you start doing mounts and unmounts from the command line. The GUI really needs to know what is going on so it can keep the configuration correct. For example, if you mount it from the GUI, then unmount it from the command line, the FreeNAS config gets messy. Then, too add to the mess, how do you fix it? The solution isn't necessarily to remount it manually and then all will be well.

The general rule that will never mess you up is to always do things in the GUI if the GUI can do what you need it to do. And be very cautious about what you want to do when the GUI doesn't support it.

If I were in your shoes I'd probably backup my current config file, reset the config to defaults and try to set everything up and see if you get the errors again.

 

[hendrik.h]

I never did anything over the console, except some clean-up-work on the share (e.g. delete some files, create dir, etc.).
Is there a way to create a partition table manually? Maybe this way i could work around the GUI doing this task, because IMO that's the point where the troubles begin.
This could explain why in the process of unmounting the console spits out "unknown file system".

 

[hendrik.h]

:D after some thinking I was able to solve the problem.
The disk could not be mounted successfully, because the mount point (folder on another disk) was either too long or it had spaces.
Now I shortened the folder name and left out any spaces. Suddenly everything works as it should.

Anyway thank you for your great effort and help in solving this!
