Description Antoine "hashar" Musso (WMF) 2013-04-30 12:19:53 UTC 
GlusterFS has caused too much troubles since we started the project.  We need to get rid of it entirely.

Comment 1 Antoine "hashar" Musso (WMF) 2013-04-30 14:09:17 UTC 
Coren has been kind enough to give me the parameters to connect to the NFS server. I will rsync the files from GlusterFS and get the puppet changes needed to point to the new mount point (/srv/project/)

Hashar: Dupe of bug 46823? If not I'd love to understand the difference.

This bug is for the beta project. I am going to migrate it to use the NFS Server that has been created for the 'tools' project.  Beta is going to be the second project to use that server, I guess once it works fine that NFS server will replace GlusterFS and thus solve bug 46823.
Comment 4 Antoine "hashar" Musso (WMF) 2013-04-30 21:15:31 UTC 
bastion apache32 and apache33 have been migrated thanks to Mark A. Pelletier.

The migration is handled by applying the role::labsnfs::client class and rebooting the instance. Once done, /data/project points to the labs NFS server instead of GlusterFS.

The page went from 560ms to 260ms. I have pinged labs-l about it.

Still have to migrate the rest of the instances though.
Comment 5 Antoine "hashar" Musso (WMF) 2013-05-20 08:14:18 UTC 
There is no way to get rid of Gluster so one will have to apply the role::labnfs::client class.  I will clean up the old Gluster /data/project to make sure nothing is using it.
