ZFS Pool error

[mattyg007]

Hi

When I tray and create my ZFS pool, it gives me an error 1 when I click apply changes.

I read somewhere that I might need to do wipe the drives completely clean before creating the pool, is this true and if so, how do I go about doing that.

Any advise.

Thanks

yes, you can use "dd" to do the job.

If you have important data, make a Backup First.

PD: Nas4free can continue working withot problem with this error, only afect to WebGUI not to data or ZFS stability, so if you have a lot of Data, perhaps do you wants to live with "Error 1 changes can not be applied".

Thanks for the reply, I've run dban on all six of my 2TB drives but I still get the same error when trying to create a pool.

Not sure if I have done something wrong or if there is something else I need to do...

Anybody

Really would like to use the ZFS file system and need to get this NAS box up and running soon.

Please post your step, perhaps you forgot some importan step.
1 Do you wipe first and last sector ? , please post the comand do you use.
2 How do you create your pool , please describe all step.

tell us what config do you want to use whit your 6 Disk, perhaps can help you to create from CLI if WebGUI do not work (Anbd tell us the name of disk (ad0,2,3,5,7,8,etc...)

PD: This user solved the problem reinstalling NAS4Free: viewtopic.php?f=57&t=261&p=714#p714

Thanks so much for getting back to me.

I have six disks, ada0, ada1, ada2, ada3, ada4, ada5.

These are the two command i ran on all the drives.
/bin/dd if=/dev/zero of=/dev/ada0 bs=512 count=1
/bin/dd if=/dev/zero of=/dev/ada0 bs=512 oseek=` count=27029168 - 2` count=2

I then logged into the web gui and went to disk management, added the disk without formatting them.
I then went to format and formatted them for ZFS pool.
Then I went to disks, ZFS and created a Virtual device
Then I went to pools, management and tried to added the pool there and that is where it gives me the error.

I have also tried a re-install but didn't help.

Hope this helps, thanks again.

Sorry, meant to tell you as well that I would like to create one raidz1 storage pool with all of my drives using all of the available drive space.

[raulfg3]

These are the two command i ran on all the drives.
/bin/dd if=/dev/zero of=/dev/ada0 bs=512 count=1
/bin/dd if=/dev/zero of=/dev/ada0 bs=512 oseek=` count=27029168 - 2` count=2

I underline and Bold the part wrong.

To avoid this problem use wipe.sh is the same code of the wiki, copy to /usr/local/sbin and check that have execute permision, try to execute on all disk of your pool like is described on wiki:http://wiki.nas4free.org/doku.php?id=faq:0129

wipe.sh

PD: 27029168 x 51 2= 13.838.934.016 /1024 /1024/1024 =12.88 GB = Strange capacity, so your numbers are wrong.

[mattyg007]

Will give it a try, thanks!

[mattyg007]

When I try and run wipe.sh it says to me command not found.

Not sure why.

[raulfg3]

use full path /usr/local/sbin/wipe.sh and remember that MUST have execute bit (777 to be sure)

[mattyg007]

Sorry, ignore that, had a moment there

Running the script now, will let you know the outcome.

[mattyg007]

Ok, after running the script on each drive which took about three days per drive, I reinstalled N4F and tried to setup my ZFS pool with the same error 1 code.

I have no idea why it keeps doing this, I am on the verge of going back over to openfiler as I desperately need a nas again, I would really like to use N4F as it looks like a much better OS for my needs and would really like to use the ZFS filesystem.

I am at a complete dead end and running out of time, any final suggestions would be truly appreciated.

[raulfg3]

Sorry , I don't have more ideas, perhaps you must try other aproach like OVM, is based on DEBIAN and do not have ZFS , but have Ext4 so perhaps works well for you.

PD: As far I know, error code 1 was gone with a reisntall from scracth on a new boot disk and "clean" DATA disk, if this do not work for you I don't kwon more to do.

I had the same problem when creating a pool. I was trying to create a pool named "Tank" and the only fix I found was to set it up with a custom mountpoint, which was "/mnt/tank". Not sure if this will work for you, but it could.

[raulfg3]

Hey, your reply is very interesting, I remember a post in the deleted old Nas4free forum of someone that upgrade from FreeNAS 8 that have the same beaviour, and the problem was that FreeNAS 8 Mont / Create Pool in a diferent folder that FreeNAS 7, so you need to impor from GUI adding desired mount point because the mount point originally in FreeNAS 8 Do not work on FreeNAS 7 = Nas4Free.

Code: Select all

zpool import -R /mnt -f poolname

or

Code: Select all

zpool import -o mountpoint=/mnt -f poolname

Hi, thanks so much for trying to assist, I tried both suggestions but still no luck.

I have decided to settle for a straight forward RAID5 and managed to set it up without any problems.

Thanks again for all your help.

I tried both suggestions but still no luck.

can you post the output of these commands?
and what say?

Code: Select all

# zfs get all | grep mountpoint
