greetings ... |

|
3 |
the server in my basement is driving me nuts ... and I start making |
4 |
mistakes ... sigh |
5 |
|
6 |
It had a LVM volume group ... consisting of two PVs ... |
7 |
|
8 |
The question in short: |
9 |
|
10 |
if I only have one PV at hand, which contains all the PEs of a given LV |
11 |
... (how) am I able to extract/export/read the contents of that LV? |
12 |
|
13 |
background: |
14 |
|
15 |
when I searched for the reason of those crashes, I removed and swapped |
16 |
and cloned hard disks all around. |
17 |
|
18 |
Right now I am on a brand new machine and want to sort out harddisks etc. |
19 |
|
20 |
One PV wasn't detected correctly ("unknown device") even though it had |
21 |
the correct uuid. I did some "pvcreate -u" on it ... and now those LVs |
22 |
on it aren't accessible anymore (can't mount or even fsck). |
23 |
|
24 |
My luck (I hope!): I have a clone of that harddrive. |
25 |
|
26 |
But I don't want to simply plug it in because I fear to ruin things as I |
27 |
already messed up that VG further by trying stuff like vgcfgrestore etc. |
28 |
|
29 |
Yes, my fault. |
30 |
|
31 |
The clone contains all the blocks for an LV I would like to keep |
32 |
somehow. So I assume it should be possible to access them? |
33 |
|
34 |
(explanation why there is no backup: the data is mythtv-stuff, video |
35 |
which is nice to have, but not critical.) |

Thanks, Stefan |
