Hi List, |
2 |
|
3 |
A few weeks ago I created a Raid 5 set for my data partition using mdadm. |
4 |
|
5 |
This works fine, but last week a short power outage caused the server to |
6 |
reboot. |
7 |
|
8 |
When I came home the server was in need of maintainance because it couldn't |
9 |
check all his filesystems. |
10 |
|
11 |
Strange fact was that the md device wasn't start... |
12 |
mdadm --assemble /dev/md1 works fine, the /etc/mdadm.conf is read the the |
13 |
raid device is started... |
14 |
|
15 |
But why doesn't start it at boot? |
16 |
|
17 |
A piece of output from dmesg: |
18 |
|
19 |
md: Autodetecting RAID arrays. |
20 |
md: autorun ... |
21 |
md: considering hdb1 ... |
22 |
md: adding hdb1 ... |
23 |
md: created md1 |
24 |
md: bind<hdb1> |
25 |
md: running: <hdb1> |
26 |
raid5: device hdb1 operational as raid disk 0 |
27 |
raid5: not enough operational devices for md1 (2/3 failed) |
28 |
RAID5 conf printout: |
29 |
--- rd:3 wd:1 fd:2 |
30 |
disk 0, o:1, dev:hdb1 |
31 |
raid5: failed to run raid set md1 |
32 |
md: pers->run() failed ... |
33 |
md: do_md_run() returned -5 |
34 |
md: md1 stopped. |
35 |
md: unbind<hdb1> |
36 |
md: export_rdev(hdb1) |
37 |
md: ... autorun DONE. |
38 |
|
39 |
It tell's me that 2/3 devices failed, but after I assemble it.. the ouput of |
40 |
mdadm --detail /dev/md1 is: |
41 |
|
