[Moosefs-users] how to increase speed of remove snapshot ?

[MarlboroMoo <mar...@gm...>]

Hi there !

i have about 5,000,000 files , and take about 5 second to make
snapshot (via mfsmakesnapshot).
but if i want to remove these snapshot ( rm -rf ), it take a very long time !
i need to take snapshot every hour , and keep the last three day.

a directory structure like below:
=========================
Snapshot-Dir/
                    |-- 201004260100/
                    |-- 201004260200/
                    |--          .
                    |--          .
                    |-- 201004280100/
=========================

if i want to remove the snapshot "201004260100" and create new one
"201004280200"
my solution is:
1) rename the directory "201004260100" to "201004280200" (mv
201004260100 201004280200)
2) make a new snapshot to override it. (mfsmakesnapshot
/path/to/source /path/to/201004280200 )

maybe we can have a command: mfsrmsnapshot to do this job
cheer !
