Subject: creating rbd snapshots via sysfs
Date: Tue, 24 Jul 2012 14:22:11 -0700 [thread overview]
Message-ID: <500F1203.9050605@inktank.com> (raw)
Right now the kernel still has one piece of rbd management duplicated
from the rbd command line tool: snapshot creation. There's nothing
special about snapshot creation that makes it advantageous to do
from the kernel, so I'd like to remove the create_snap sysfs interface.
That is, /sys/bus/rbd/devices/<id>/create_snap would be removed.
Does anyone rely on the sysfs interface for creating rbd snapshots?
If so, how hard would it be to replace with:
rbd snap create pool/image@snap
Is there any benefit to the sysfs interface that I'm missing?
Josh
