To my knowledge Gluster lacks performance when handling large files like vm images. RedHat is working on a new version which should perform better.

Betreff: [PVE-User] NFS no downtime snapshots

Hi,

We currently run Citrix XenServer as our virtualization platform.  After running for a few years on iSCSI, we switched to NFS (flakey iSCSI hardware and snapshots).

One thing XenServer does is zero downtime NFS snapshots, using a copy-on-write system.  When the snapshot is removed, it 'coalesces' the original file and the new cow file.

Are there plans to implement a zero downtime NFS snapshot solution for Proxmox?  Or better yet, a GlusterFS one?

Gerald
