LVM Snapshot time limit during creation


sometimes I get the following error:

The external command failed to start. Error message: Duplicati.Library.Interface.UserInformationException: The external command failed to complete within the set time limit: /usr/lib/duplicati/lvm-scripts/ …

How long is the time limit and is it possible to increase the time limit?


It appears to be 30 seconds (despite the comment on it), always has been, and isn’t user-configurable.

Some sources say LVM snapshot creation is instantaneous (it just sets up to copy-on-write later, right?).
I suppose you could open an Issue to increase it, but it might help if you can provide supporting analysis.
The change itself looks easy enough, except perhaps for testing, which maybe you can do in a Canary?.
