different name of the same device.

Hi,

We receive following error during the restore attempt:

No code has been generated to restore device pv:/dev/disk/by-id/cciss-3600508b1001fffffa004f7b3f209000b-part2

The cause is the mismatch of device name in disklayout.conf - the lvmdev and part definition refer to the different names of the same device.

disk /dev/cciss/c0d0 72833679360 msdos
part /dev/cciss/c0d0 205599744 32256 primary boot /dev/cciss/c0d0p1
part /dev/cciss/c0d0 72620997120 205632000 primary lvm /dev/cciss/c0d0p2
lvmdev /dev/vg00 /dev/disk/by-id/cciss-3600508b1001fffffa004f7b3f209000b-part2 7fWwOV-nd4W-G0oA-0SE8-Oy89-NGpH-qHRoN3 141837885

This issue was observed on SLES11 SP3, after we specified

preferred_names = [ "^/dev/disk/by-id/" ]

in lvm.conf.

We can reproduce it with recent 1.15 as well as 1.14 version.

The easy workaround is to edit disklayout.conf manually before the restore.

@pavoldomin Would be nice to see the logging of a debug session with savelayout... and perhaps the ls -l of the /dev links from the cciss stuff.
@jhoekx do you have am idea if there is an easy way to get around?

[jhoekx]

There is no easy way around. The get_device_name function should be taught to convert by-id names to the format used for the partitions. We should make sure we call that function when writing the lvmdev line to disklayout.conf.

@pavoldomin could you attach the log file made by rear -vD savelayout as a gist?

[gdha]

@pavoldomin could you also paste the content of the file /var/lib/rear/recovery/diskbyid_mappings ?

[pavoldomin]

Hi, sorry for latency.
/dev/disk/by-id listing, diskbyid_mappings content and logfile are here

@pavoldomin Please try out rear-1.15-4.git201310041248.noarch.rpm (download it from http://download.opensuse.org/repositories/Archiving:/Backup:/Rear:/Snapshot/ )

[gdha]

@pavoldomin Did you get the chance to try it out already?

[pavoldomin]

Fixed; tested with 1.15-git201310211300
