The same version of lvm2 is used in Ubuntu Karmic, and exhibits similar behaviour. My system is running 2.6.31-20-generic #57-Ubuntu SMP AMD64 (current karmic-proposed).
Ubuntu bug is filed here, however I suspect this is the same issue. https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/530240 Below is the series of commands executed on my logical volumes, two of them currently open were extended 20GB (prior to file system resize), and then I wanted to consume the remaining extends on one of them. Prior to executing these commands I removed two other existing volumes in the same group in order to free up the space. My pv's sit on top of a RAID1 md device as shown below, similar to the original report. >From dpkg: ii lvm2 2.02.39-0ubuntu11 >From dmesg: [13442.816905] lvextend[6576]: segfault at 0 ip 00000000004564eb sp 00007fff6dbc1a60 error 4 in lvm[400000+8e000] >From console: r...@laptop:/mnt# lvs LV VG Attr LSize Origin Snap% Move Log Copy% Convert home raid -wi-ao 20.00G virt raid -wi-ao 20.00G r...@laptop:/mnt# pvs PV VG Fmt Attr PSize PFree /dev/md1 raid lvm2 a- 82.02G 42.02G r...@laptop:/mnt# lvextend -L +20G /dev/raid/home Extending logical volume home to 40.00 GB Logical volume home successfully resized r...@laptop:/mnt# lvextend -L +20G /dev/raid/virt Extending logical volume virt to 40.00 GB Logical volume virt successfully resized r...@laptop:/mnt# pvs PV VG Fmt Attr PSize PFree /dev/md1 raid lvm2 a- 82.02G 2.02G r...@laptop:/mnt# lvs LV VG Attr LSize Origin Snap% Move Log Copy% Convert home raid -wi-ao 40.00G virt raid -wi-ao 40.00G r...@laptop:/mnt# pvs PV VG Fmt Attr PSize PFree /dev/md1 raid lvm2 a- 82.02G 2.02G r...@laptop:/mnt# lvextend -l +100%PVS /dev/raid/home Segmentation fault -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
