Hi all.
I am working on bug 1503390. (status=None while delete is in progress
)
I was doing analysis of problem and found that yes its there.
I reproduced it.
Now the two solutions proposed..
1)Either say the status as deleting for such snapshots ?
2)lets not list such snapshots in list ..
I see that
If we implement solution1 .. then it doesn’t work as …..
we reach the same Situation of (snapshot present but snapshot_instance
absent)
in two cases
When snapshot is deleted and when snapshot is created …
Now if I set status as deleting(to be shown in list for snapshots with
no snapshot_instances)
it will be a wrong information when we are creating the snapshot.
And list function – can not differentiate state (snapshot present but
snapshot_instance absent)
whether its due to creation or deletion. PCIIMW…
Another way to do this is .. let create delete path set the status to a
special state .
which if list operation obtains .. can understand how to interpret it …
But setting status also is not possible as status resides in
snapshot_instances table ..
row for which is not created yet in create path .. we can not set staus …!!!
Do you think that
STATUS_NEW = 'new'
STATUS_CREATING = 'creating'
STATUS_DELETING = 'deleting'
STATUS_DELETED = 'deleted'
STATUS_ERROR = 'error'
STATUS_ERROR_DELETING = 'error_deleting'
STATUS_AVAILABLE = 'available'
STATUS_ACTIVE = 'active'
STATUS_INACTIVE = 'inactive'>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
STATUS_MANAGING = 'manage_starting'
STATUS_MANAGE_ERROR = 'manage_error'
STATUS_UNMANAGING = 'unmanage_starting'
STATUS_UNMANAGE_ERROR = 'unmanage_error'
STATUS_UNMANAGED = 'unmanaged'
STATUS_EXTENDING = 'extending'
Do you think that setting state as *_some neutral state like
state_inactive .._*
will help?
it will be same in both creation and deletion path ?
so should we go with 2^nd solution ? lets not show such shares in list ?
I like the second solution. Rather than making up a neutral state, just
don't list snapshots with no instances. If the snapshot was getting
deleted, then very soon there won't be anything to show, and if the
snapshot was just getting created, the client can retry the query later
and see the snapshot after a short time.
