removed old array, can't make new w/ mdadm

post #1 of 11
Thread Starter 
I did have a level 0 array amongs 4 disks...but 1 disk is bad so I wanted to recreate it.
I stopped and removed the array

Quote:
mdadm --stop /dev/md0
mdadm --remove /dev/md0
I recreate the partitions, rebooted, wiped the drive with zeros,
and as soon as I recreate a partition on /dev/sdb (my first drive in the set)... I get this:
Quote:
mdadm --create /dev/md0 --raid-devices=3 --level=5 --verbose /dev/sdb1 /dev/sdc1 /dev/sdd1
mdadm: layout defaults to left-symmetric
mdadm: chunk size defaults to 64K
mdadm: Cannot open /dev/sdb1: Device or resource busy
mdadm: create aborted
root@homebuntu:~# cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md_d0 : inactive sdb1[0](S)
625129216 blocks

unused devices: <none>
Also tried:
Quote:
root@homebuntu:~# mdadm --zero-superblock /dev/sdb
mdadm: Couldn't open /dev/sdb for write - not zeroing
root@homebuntu:~# mdadm --zero-superblock /dev/sdb1
mdadm: Couldn't open /dev/sdb1 for write - not zeroing
Also notice in the mdstat, there's a multidisk device by the name of md_d0? that wasn't there before.. only since I removed and tried recreating the array.

anyone have any idea?


Edit: Also wanted to add that after I zeroed the drive and rebooted, that /proc/mdstat was clean like I'd expect. But upon trying to create the array, it reported that /dev/sdb1 was too small "0k"

I can only recommend that you recreate the partitions. Something on /dev/sdb is messed up.

Thanks. I've done this. As soon as I do recreate it, the os gets a hold of it.

Okay... this is weird. Try clearing the partition table completely:
Code:
sudo dd if=/dev/sdb of=/dev/zero count=512
Then reload the partition table:
Code:
sudo hdparm -z /dev/sdb
Then recreate the partitions (I find cfdisk easier to use than fdisk):
Code:
cfdisk /dev/sdb
And then try remaking the MD array:
Code:
mdadm -C /dev/md0 -n3 -l5 /dev/sd{b..d}1

I'll give that a shot. I did try zeroing several GB of disk; at the beginning, end, and near the 640G partition break(in case it looked at the end of the part).

the only thing I didn't do was to use hdparm to write the table, I used fdisk then it fixes the table on write.

I'll let you know how it goes.

That's even more odd then.
Ok, clean the harddrive to remove the partition table:
Code:
sudo dd if=/dev/sdb of=/dev/zero count=512
Then reload:
Code:
sudo hdparm -z /dev/sdb
THEN try removing the /dev/sdb1 node (it could be faulty):
I forgot to mention the /dev/sdb node too:
Code:
sudo rm /dev/sdb1
sudo rm /dev/sdb
And then reboot:
Code:
sudo reboot
Then try remaking the partition table and redoing the mdadm thingy.

mini update...
tried that sequence...

as soon as I create a partition on dev/sdb, I get info populated in /proc/mdstat.

So I'm zero-ing the entire drive... all 1TB of it.

good thing for 'screen'

zero'ing the entire drive fixed it. So it was just a matter of zeroing the right part. I tried the logical places before. beginnging and end of disk and partition -- I wonder if I got the skip/seek arguments wrong on it.

New raid5 array being built now.
