I've finally read this thread and have a few comments.
In the new world, I wonder if it makes sense to place a share without a
The basic mark and notify approach makes sense. With that, do leasees
have expiration times, or just issue times?
As a server admin, I still want to ability to
see what the storage in use is
by age of lease
force expiration even if the above rules don't support it
by old leases
for particular lessors
As a user, I would like to be able to renew leases for my existing trees
of data. I see that as doing a walk over a few rootcaps, similar to
deep-check --add-lease now. I don't see how it makes sense not to
walk the tree. When doing this, I would like to know
how much data is covered by each walk (to make sure I marked what I
how much data is on each server (because I'm curious, and it seems
this can be kept track of for free)
I do not follow the notion that leases can be renewed without walking fs
trees. I do understand that one could walk once and then renew those
leases, but I don't see that as matching very many real use cases.
How do you know a directory doesn't have a new child from the last time,
perhaps added by another node (even if it was also me)?
