Dear Paul.

I appreciate for your reply.

I worry about ENOSPC with XFS and meta-data corrupt in dm-thin.
I will test it.  ( https://lwn.net/Articles/592645/ )

Thanks a lot!

Hi

dm-thinp is fully supported in RHEL6 and RHEL7 (and presumably their clones!) The downstream Red Hat Gluster Storage product has been using dm-thinp for a while (RHEL 6.5 I think)

check out these slides from last years Red Hat Summit.
http://www.slideshare.net/Red_Hat_Storage/snapshots-in-red-hat-storage-server-overview-quickstart

Using dm-thinp with a modern kernel/lvm shouldn't be a problem.

Cheers
