On Ubuntu 14, it doesn't seem to work with monitoring = 1 set, either. I had also tried doing vgchange --monitor y --poll y volumegroup, and lvcreate --snapshot --monitor y ... and there was no effect.
Testing on Ubuntu 16 now -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lvm2 in Ubuntu. https://bugs.launchpad.net/bugs/1424114 Title: lvm snapshot is not being autoextended Status in lvm2 package in Ubuntu: Confirmed Bug description: After setting auto extend threshold and rebooting, lvm snapshots are not being auto extended. Steps to recreate: 1. Using Ubuntu 14.04 LTS 2. Set snapshot_autoextend_threshold to less than 100 # grep autoext /etc/lvm/lvm.conf snapshot_autoextend_threshold = 50 snapshot_autoextend_percent = 20 3. Reboot server to have lvm reread lvm.conf 4. Create a snapshot of a mounted logical volume # lvcreate -s /dev/testVG/testLV -L 1G -n testLVsnap 5. Make modifications to mounted logical volume 6. List logical volumes and snapshots # lvs LV VG Attr LSize Pool Origin Data% Move Log Copy% Convert testLV testVG owi-aos-- 10.00g testLVsnap testVG swi-a-s-- 1.00g testLV 95.04 What I expected to have happened: Once Data% of snapshot reached the snapshot_autoextend_threshold, the snapshot logical volume should have been auto extended.
