Description Ori Gofen 2014-07-27 14:01:50 UTC
Description of problem:
Right now when creating a large block disk (the larger the disk,the larger the problem)
and marking "wipe after delete" flag as 'True',then removing this disk.
disk existence is wiped from the UI while actually,removing this kind of disk takes a lot of time(since vdsm has to fill the whole disk with zero's).
this can be very misleading to an unaware sysadmin.

for example:
Deleting two 30G disks(wipe_after_delete='True') on iscsi took almost 25 minutes
async task table reported this two assignment as being executed

engine=# SELECT step_id,action_type,task_params_class from async_tasks;
               step_id                | action_type |                     task_params_class

and during all this time (25 minuts),UI reported on an unused ISCSI domain(with no disks or vm's on it) with 1G free space(out of 65G)

RFE is needed to help user follow the process of deleting this kind of disk

What's probably needed here is some sort of introspection into VDSM's garbage collection mechanism, once one is introduced (post SPM removal).

Comment 2 Adam Litke 2015-09-08 13:41:31 UTC
Currently we report the total space and free space.  We could add another figure (eg. Total Garbage or Reclaimable) to report in the storage domain details.  This figure could be calculated and updated by engine without any vdsm intervention.

Closing old RFEs.
If relevant please re-open and explain why.
