Hi Is it possible to create snapshots in glusterfs like that in lvm? -- Thanks & Regards visco
I dont believe theres a snapshot translator. I'm not sure how there would be since gluster relies on the underlying filesystem. What you could do is put glusters underlying filesystem on LVM, and take a snapshot. then, if you wanted, you could run another gluster process on top of the snapshot filesystem.

Thanks keith for the reply I was asking because there was a mention of writable snapshot translator in v2.1. So at present glusterfs is not having anysnapshot like that provided by lvm, right?

"Distributed writable snapshot" is currently under development. Implementing snapshots inside GlusterFS framework will be an elegant and portable solution than relying on underlying disk subsystems's ability. Expected availability is around May 2009 with the 2.1 release. For time being, you can try Keith's idea. -- Anand Babu Periasamy GPG Key ID: 0x62E15A31 Blog [http://ab.multics.org] GlusterFS [http://www.gluster.org] The GNU Operating System [http://www.gnu.org] Keith Freedman wrote:> I dont believe theres a snapshot translator.
