Old HDDs came from a Intel Software RAID controller

[jader31]

Hi

I'm trying to use used HDDs from another computer. They were used under a (fake ??) RAID controller onboard (Intel motherboard/controller).
Now these HDDs are in a HP N40L computer.
I'm unable to use those disks (fails on format with error 1 message when try to apply changes) and I can see this on dmesg:

Code: Select all

On IRC I've talked to others and tryed to wipe the disk using script wipe.sh but just get operation not allowed. See below:

Code: Select all

nas:~# /mnt/wipe.sh 
What disk do you want
to wipe? For example - ada1 :
ada0
OK, in 5 seconds I will destroy all data on ada0!
Press CTRL+C to abort!
dd: /dev/ada0: Operation not permitted
dd: /dev/ada0: Operation not permitted
nas:~# 

I'm far away from computer, using remote SSH. just have access thru my own linux server and redirect.

So I'm out of ideas for now... and asking for help.

Thanks

Hello,

You need to be root (default when you did not change it it is the user "admin") to do this task. Type "su", then enter the password (standard is nas4free).
Be really careful to choose the right disk

your disk can't be mounted to wipe it, only detected by Nas4Free. if one disk is part of any active pool /Raid etc ( is mounted), can not be wiped.

and be totally sure what disk do you want to wipe, because is one way only action .

I think I solved it!
I search forums and found 2 threads related:
viewtopic.php?f=59&t=2206
and
viewtopic.php?f=16&t=1404

where I found commands about to stop GEOM raid from Hardware controllers.
So below it's what I did to help next one!

Code: Select all

nas:~# gpart show
=>      0  3948544  da0  BSD  (1.9G)
        0   225792    1  freebsd-ufs  (110M)
   225792  3722752       - free -  (1.8G)

=>        63  3907039169  raid/r0  MBR  (1.8T)
          63        1985           - free -  (992k)
        2048  3907033088        1  ntfs  (1.8T)
  3907035136        4096           - free -  (2.0M)

OK... there are a 1.8TB RAID raid/r0 with a NTFS partition...

Code: Select all

nas:~# graid stop r0
graid: Array 'r0' not found.
nas:~# graid stop raid/r0
graid: Array 'raid/r0' not found.

hum.... do not work...

Code: Select all

nas:~# graid status 
   Name   Status  Components
raid/r0  OPTIMAL  ada0 (ACTIVE (ACTIVE))
                  ada1 (ACTIVE (ACTIVE))
                  ada2 (ACTIVE (ACTIVE))
                  ada3 (ACTIVE (ACTIVE))
nas:~# graid status -g
          Name   Status  Components
Intel-6823ede0  OPTIMAL  ada0 (ACTIVE (ACTIVE))
                         ada1 (ACTIVE (ACTIVE))
                         ada2 (ACTIVE (ACTIVE))
                         ada3 (ACTIVE (ACTIVE))
nas:~# graid stop Intel-6823ede0
nas:~# graid status Intel-6823ede0
graid: No such geom: Intel-6823ede0.
nas:~# graid status -g

Now it appears to be removed!

Code: Select all

nas:~# gpart show
=>      0  3948544  da0  BSD  (1.9G)
        0   225792    1  freebsd-ufs  (110M)
   225792  3722752       - free -  (1.8G)

yes... no more 1.8TB RAID.

So I went to ZFS page and activate my raidz1 array and now it show at GUI!

Attached you'll find the status report I generated BEFORE and AFTER my changes.

I'll reboot the N4F now...nothing to loose anyway.
