Hello,
Another problem related to the custom definition of the lvm filter and
preferred_names discovered.
The problem comes from the colon in md device name (because md array was
built with --name option) like
#pvs
/dev/disk/by-id/md-name-hostname:NA3scs vgNA3scs lvm2 a-- 5.00g 4.00g
leading to the
#rear -v -D savelayout
Relax-and-Recover 1.15-git201310211300 / 2013-10-21
Using log file: /var/log/rear/rear-hostname.log
Creating disk layout
ERROR: BUG BUG BUG! Empty string passed to get_device_name
=== Issue report ===
Please report this unexpected issue at: https://github.com/rear/rear/issues
Also include the relevant bits from /var/log/rear/rear-hostname.log
HINT: If you can reproduce the issue, try using the -d or -D option !
====================
Aborting due to an error, check /var/log/rear/rear-hostname.log for details
Hopefully relevant (and slightly censored) part of the logfile is here: https://gist.github.com/pavoldomin/0242b6d92fc45294996d
Worth adding, that this grep than returns two entries on this particular server:
#grep '^md-name-hostname' /var/lib/rear/recovery/diskbyid_mappings
md-name-hostname:NA3ora
md-name-hostname:NA3scs md35
As expected, if we add /dev/md* to the filter as well as
preferred_names definition in lvm.conf, the problem ceases.

perhaps we need to rewrite
/usr/share/rear/layout/save/GNU/Linux/22_lvm_layout.sh a bit to avoid
working with :

@pavoldomin due to lack of time will push this issue back to milestone v1.17

as it a request from one customer only (so far) we classified as looking for sponsoring.

As after one year no-one showed interest in this missing feature we classified it as 'wont fix'
