Re: [Moosefs-users] upcoming quotas and metadata format change

Hi

 

The new metadata format is something like an "extension" to the 1.6 branch
metadata. Upgrading to 1.7 would be easy - you won't have to think about
these issues.

 

 

Kind regards

Subject: [Moosefs-users] upcoming quotas and metadata format change

 

We have multiple research groups that might be able to make use of MooseFS,
and I'm trying to avoid having multiple installations of it.  Per-directory
quotas would make this easier to reliably implement.

I note that in the MooseFS roadmap, http://www.moosefs.org/roadmap.html,
that per-directory quota support is planned to be added in version 1.7, and
that a new metadata file format will be introduced.  Will version 1.7 be
compatible with files written under version 1.6, and if so will they be
compatible with the quota implementation?  If there is some sort of metadata
conversion that will be necessary, what will this process entail?
