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 |
|
7 |
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 |
