Hello,
I have a NAS whith 8 HDD :
five 3To HDD
four 2To HDD
I already created a RAIDZ-2 with the five 3TO HDD and I want to create a RAID5 with the four 2To HDD.
But they don't appear in the format menu so I can't format them in software RAID as you can see below :
But the appear in the disk management menu :
WTF ??
Thank you
Best regard

one of your drives is still listed as RAID5 device.
You can try using the shell and do gpart destroy on ada0, ada2, ada3, ada7
Then import the drives and see if it worked

My apologizes !
I was saying that when I try gpart destroy command it doesn't works I have those error messages :
access denied
or
sudo : not found.
But now I logged as root and when I try gpart destroy ada0 (for example) I have this message :
invalid number of arguments
I will try gepart destroy /dev/ada0
edit : gepart destroy /dev/ada0 : invalid number of arguments

you can create it on windows and copy it to a share
however you should become familiar with the shell. see
http://wiki.nas4free.org/doku.php?id=faq:0128
and

I started nano and I paste one of the two script, then I saved the file as whipe.sh.
Then I did this :
Code: Select all
GNU nano 2.2.6 File: wipe.sh
#!/bin/bash
echo "What disk do you want"
echo "to wipe? For example - ada1 :"
read disk
echo "OK, in 10 seconds I will destroy all data on $disk!"
echo "Press CTRL+C to abort!"
sleep 10
diskinfo ${disk} | while read disk sectorsize size sectors other
do
# Delete MBR, GPT Primary, ZFS(L0L1)/other partition table.
/bin/dd if=/dev/zero of=/dev/${disk} bs=${sectorsize} count=8
# Delete GEOM metadata, GPT Secondary(L2L3).
/bin/dd if=/dev/zero of=/dev/${disk} bs=${sectorsize} oseek=$(expr
$sectors - 8) count=8
done
[ Wrote 15 lines ]
Code: Select all
nas4free:~# ./wipe.sh
./wipe.sh: Permission denied.
nas4free:~# sudo wipe.sh
sudo: Command not found.
nas4free:~#
Thanks for the two links

Ok thank you It work but I think there is an error in the script (In the FAQ it says Make sure you preserve the integrity of each line if you copy and paste the script, but maybe have I something to adapt to my config that I have not done)
Code: Select all
nas4free:~# chmod a+x wipe.sh
nas4free:~# ./wipe.sh
What disk do you want
to wipe? For example - ada1 :
ada0
OK, in 10 seconds I will destroy all data on ada0!
Press CTRL+C to abort!
8+0 records in
8+0 records out
4096 bytes transferred in 0.260799 secs (15706 bytes/sec)
expr: syntax error
./wipe.sh: line 14: 3907029168: command not found
dd: no value specified for oseek
