Re: [Gluster-devel] Issues with fallocate, discard and zerofill

[Anand Avati]

Shishir,

Is this in reference to the dht open file rebalance (of replaying the operations to the destination server)? I am assuming so, as that is something which has to be handled.

The other question is how should fallocate/discard be handled by self-heal in AFR. I'm not sure how important it is, but will be certainly good to bounce some ideas off here. Maybe we should implement a fiemap fop to query extents/holes and replay them in the other serverl?

Hi Avati, Brian,

During the recently held gluster meetup, Shishir mentioned about a
potential problem (related to fd migration etc) in the zerofill
implementation (http://review.gluster.org/#/c/5327/) and also
mentioned that same/similar issues are present with fallocate and
discard implementations. Since zerofill has been modelled on
fallocate/discard, I was wondering if it would be possible to address
these issues in fallocate/discard first so that we could potentially
follow the same in zerofill implementation.

Regards,
Bharata.
