Package: fai-setup-storage Version: 4.0.6 Severity: important fai-setup-storage fails when trying to do an install to a machine using lvm when a partition is requested to be preserved. This is a regression from fai-setup-storage 3.4.8 where this worked fine (i.e. in squeeze)
I actually believe it has a problem any time the hard disk previously contains an lvm volumegroup, but I haven't got time to test this configuration. I've talked on the upstream users' mailing list a bit and there appears to be a number of issues. First, setup-storage depends on liblinux-lvm-perl While that library has been redone, both versions of it just seems to pass through the same problem. The ultimate problem is that logical volume information is derived from executing the "vgdisplay -v" command. The output from this command has changed between squeeze and wheezy. The older version of this command has fewer fields. snippet of older output: LV Name /dev/vg/var VG Name vg snippit of newer output: LV Path /dev/vg/var LV Name var VG Name vg They've added a field, and changed what is contained in the old named field. I've filed a bug with liblinux-lvm-perl about the fact that they don't pass on LV Path. Even after fixing the problem with liblinux-lvm-perl, setup-storage has problems with wipefs. In my case I error out with: Executing: wipefs -a vg/fscache ... wipefs: error: vg/fscache: probing initialization failed I don't see how that code ever could have worked because I don't think that $vg/$lv could ever be a valid path for the wipefs command. This is clearly what the code is trying to do. Since the fai-setup-storage code appears to be in a bit of trouble (somebody made a bunch of commits back in 2011 and hasn't been back to clean it up), I have managed to kludge 3.4.8 fai-setup-storage to work with the 4.0.6 fai packages for my local needs. I've recommended the following on the fai-users mailing list: 1. liblinux-lvm-perl be changed to pass the new LV Path field. 2. downgrade fai-setup-storage back to a known working version (3.4.8?) 3. fix the logic in fai-setup-storage to deal with the multiple fields for the LV in the manner described by Thomas Neumann on the fai-users mailing list. I'm not sure how the Debian package should go forward, but I wanted to make you aware of the problem. Let me know if I can provide further information. -Ken Hahn -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
