Ceph » rbd

The order in which objects with static storage duration in different TUs are initialized is undefined. If the compiler chooses to initialize Shell::Action objects in action/Trash.cc before Shell::Action objects in action/TrashPurgeSchedule.cc, all "rbd trash purge schedule ..." commands get shadowed by "rbd trash purge" command:

$ rbd trash purge schedule list
rbd: too many arguments

The confusing error arises because "rbd trash purge" takes a single positional argument. "schedule" gets interpreted as <pool-spec> and "list" generates an error.

Help is busted the same way:

$ rbd help trash purge schedule list
usage: rbd trash purge [--pool <pool>] [--namespace <namespace>] 
                       [--no-progress] [--expired-before <expired-before>] 
                       [--threshold <threshold>] 
                       <pool-spec> 

Remove all expired images from trash.
