I’m installing ReaR into a server using LVs with stripes, as the following exemple:
Server0:/var/lib/rear/layout # lvs -o +devices | grep LVSample1
LVSample1 VGTemp -wi-ao 60.00g
/dev/mapper/temp_1(0),/dev/mapper/temp_2(0),/dev/mapper/temp_3(0),/dev/mapper/temp_4(0)
I see the layout generated ignores this configuration:
Server0:/var/lib/rear/layout # grep LVSample1 disklayout.conf
lvmvol /dev/VGTemp LVSample1 960 125829120
fs /dev/mapper/VGTemp-LVSample1 /sample1 reiserfs
uuid=1d1e43d4-968f-46b9-bb55-ad6b773ae93c label=
options=rw,notail,acl,user_xattr
Server0:/var/lib/rear/layout #
Commented at the Mailing List, and it seems to be an missing feature. I'm trying to attach the output of 'rear -vdD savelayout', as D'haese Gratien has suggested.

@iaragones you mailed me the log file created, but I would rather see
the log created by rear -vdD savelayout and attach it to
gist.github.com

There's only this log file available... I see no more output to send to you. Where is the log you need supposed to be located?

The /var/log/rear/rear-bcnabpccip01.log file created just now will do.

I only see the option of attaching images... I'm sending it via e-mail again.

Our current code base does not (yet) support striped lvm lvols. It will take considerable time to get this implemented. We do accept a pull request...

When cloning you are not sure what kind of disks you will have, so I think striping should not be blindly applied. It is better the way it is now. You can proof me wrong, of course...

Usually, when you want to recover/clone a server, you already know how many disks you need to recover the same status the server were before a disaster... In my opinion, the recover process may leave the new server exactly with the same configurations the original was. Obviously, you ever can modify the layout to make it different, but in my opinion it’s better to make the defaults to be equal to the actual scenario.
