Occasional failure setting up lvmcluster storage #14

Open gibmat opened 2 months ago

Occasionally in the "Add storage pools" task (maybe 1/20 runs) I see the following failure:

This is particularly weird because the --addtag is already a TryRunCommand so it will have tried a bunch of time before failing.

It'd probably be useful to look at the vgs, lvmlockctl and sanlock following a failure to see what's going on.
