Hi, I'm running a 3.10 kernel with LVM 2.02.95. I'm running into a problem where activating snapshots can take quite a long time, roughly one minute per 25GB of delta between the snapshot and the origin volume. (See below for my test procedure.)
As a side question, currently we have a script which runs "vgchange -ay <vg>", which will activate the VG.
This script appears to activate the LVs within the VG serially rather than in parallel. Does it do any processing to determine in which order to activate the LVs?
The reason I ask is that we have an overall timeout on the activate phase, after which we'll put any un-activated LVs into an error state. It would be a shame to try to activate a snapshotted LV first, and then timeout without activating any of the non-snapshotted LVs.
