Description Corey Marthaler 2006-01-25 16:52:02 EST
Description of problem:
As a snapshot reaches a highwater mark it would be nice for the user if there
were warnings printed out to the console that the snapshot is becoming full and
that something needs to be done before access to your data is lost. 

Additional info:
This is related to the bz 174742 issue.

preview of snapshot monitoring DSO

Attaching patch for lvm2 2.02.19 implementing simple snapshot monitoring DSO.
Currently we have no configuration file for dmeventd, so snapshot warning mark
and timeout interval for checks are hardcoded. This is just for preview - lvm2
code will need modifications to enable snapshot monitoring without some hacks.
Monitoring is activated by setting lvm.conf { snapshot_library=<file> }
Comment 7 RHEL Product and Program Management 2007-03-09 20:10:51 EST
This bugzilla had previously been approved for engineering
consideration but Red Hat Product Management is currently reevaluating
this issue for inclusion in RHEL4.6.

Forward port of the snapshot DSO patch. Lightly tested, seems to work. Needs to
be cleaned up before inclusion.
