Hello list, |
| 2 |
|
| 3 |
(I've been off-line for ten days and I haven't yet caught up with the list. I |
| 4 |
had to send my machine to its maker to have a cooling-system hardware fault |
| 5 |
fixed.) |
| 6 |
|

I've added two SSDs to my workstation, intending to create a RAID-1 array on |
| 8 |
them to store backups (which may be another question when I've got the setup |
| 9 |
right), but I cannot create the array to create LVM. |
| 10 |
|
| 11 |
Each disk has an 80GiB NTFS partition in case I want to install Windows, then |
| 12 |
a 500GiB ext2 partition. |
| 13 |
|
| 14 |
When I run "mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda2 /dev/ |
| 15 |
sdb2", this is what I get: |
| 16 |
|
| 17 |
# mdadm --stop /dev/md0 |
| 18 |
mdadm: stopped /dev/md0 |
| 19 |
# mdadm: /dev/sda2 appears to contain an ext2fs file system |
| 20 |
size=524288000K mtime=Thu Jan 1 01:00:00 1970 |
| 21 |
mdadm: /dev/sdb2 appears to contain an ext2fs file system |
| 22 |
size=524288000K mtime=Thu Jan 1 01:00:00 1970 |
| 23 |
Continue creating array? y |
| 24 |
mdadm: RUN_ARRAY failed: Invalid argument |
| 25 |
|
| 26 |
If I boot from SysRescCD I also get "device /dev/sda2 exists but is not an md |
| 27 |
device." I also had to "mdadm --stop /dev/md127" since that OS calls the first |
| 28 |
array that. |
| 29 |
|
| 30 |
I've tried with a GPT disk header and with an MSDOS one, with similar results. |
| 31 |
Also with /etc/init.d/mdraid not running, with it started on my command and |
| 32 |
with it in the boot runlevel. Each time I changed anything I rebooted before |
| 33 |
trying anything else. |
| 34 |
|
| 35 |
I must be missing something, in spite of following the wiki instructions. Can |
| 36 |
someone help an old duffer out? |
| 37 |
