Description Alasdair Kergon 2012-04-20 20:42:16 UTC 
The dmeventd architecture needs some changes to support monitoring large numbers of volumes, such as we might have with thin pools.
Comment 1 Alasdair Kergon 2012-04-20 20:43:31 UTC 
(the solution might or might not involve using libdaemon)
Comment 2 Tom Lavigne 2012-09-07 15:22:07 UTC 
This request was evaluated by Red Hat Product Management for 
inclusion in the current release of Red Hat Enterprise Linux.
Since we are unable to provide this feature at this time,  
it has been proposed for the next release of 
Red Hat Enterprise Linux.
Comment 3 Jonathan Earl Brassow 2019-08-07 20:23:23 UTC 
Perhaps we could move over to the newer event interface that was originally put forth for stratis.  Giving this to Joe to think about.
Comment 4 Jonathan Earl Brassow 2021-05-20 15:41:14 UTC 
The kernel side has been handled by Mikulas, but dmeventd does not yet utilize it (and it should).
