Note: /mnt (as seen in the logs) is a scratch space with 32GB free. The key to this puzzle is what is $distro? Anyhow this happens because virt-resize cannot resize logical partitions: http://libguestfs.org/virt-resize.1.html#logical-partitions so if you point the 'expand' setting at one it isn't going to work. There is ongoing work upstream to try to support logical partitions in virt-resize -- see upstream mailing list passim ad nauseam. In this case $distro was both debian-7 and debian-8. I found that the culprit is util-linux 2.26.2-3 from Sid. It works with util-linux 2.25.2-6 from Jessie & Stretch. Created attachment 1028171 [details] resize.txt I think this is because of the upstream rewrite of sfdisk. See also: https://www.redhat.com/archives/libguestfs/2015-May/msg00080.html I can reproduce this with util-linux-2.26.2-1.fc23.x86_64 Full log is attached. This is a known regression in util-linux 2.26.x, see also https://bugzilla.redhat.com/show_bug.cgi?id=1248115#c7 Regarding Debian, either you ask the Debian maintainer of util-linux to backport the upstream commit to the 2.26.2 currently in testing & unstable, or simply wait for util-linux 2.27 to be released and packaged in Debian unstable. OK. I'm still having the problem with 2.27-rc2 which is available in Debian experimental but I'll try hunting down the commit for 2.26. Thanks. |
