Help.
I have been using mdadm raid5 array on my old ubuntu for over 5 years withount problem. Then I decided to reinstall.
Now, I got new fresh clean install of Ubuntu (lucid lynx) and did commands
Code:
sudo apt-get install mdadm
sudo mdadm --create /dev/md0 --level=5 -n 4 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1
which failed with (as far as I remember)
Code:
/dev/sda device or resource busy
/dev/sdb seems to be part of raid ...
/dev/sdc seems to be part of raid ...
/dev/sdd seems to be part of raid ...
Then I went to google for solution. After some time, I tried that command again but I have got somthing like
Code:
/dev/sda is too small. 0K
/dev/sdb device or resource busy
/dev/sdc seems to be part of raid ...
/dev/sdd seems to be part of raid ...
sda is now _empty_ and sdb busy now? I got feeling something is messing with my disk, finished with first one and now it is destroying my second one. I kicked power cord out of my computer, disconnected these 4 disks and now I am seeking for profesional help.
