Right now I can think in three main reasons: The first reason, performance (I do not know Gluster and its performance and if the read and write speed are satisfactory). Please if you can make a test, post the results.
Second consistency, I do not know Gluster, but swift that is also a Distributed File System is not consistency and they make it pretty clear on their page (http://docs.openstack.org/developer/swift/) "Swift is a highly available, distributed, eventually consistent object/blob store...". I would not accept to storage my VMs images on a FS that is eventually consistent. Third, network, I haven't used this kind of FS, but I can image that it uses a lot of bandwidth to keep synchronizing, managing and securing the data. So, managing the networking would be a pain. 2013/9/11 Olivier Mauras <oliv...@core-hosting.net> > > > Hi, > > Those thinking that it's not a good idea, do you mind > explaining your point of view? > GlusterFS seems like the only real > alternative to a highly priced SAN for the primary storage... > > > Thanks, > Olivier > > On 2013-09-11 15:08, Rafael Weingartner wrote: > > > I > totally agree with Tomasz, I do not think that using a distributed FS > as > > primary storage is a good idea, but as a secondary it sounds > interesting. > > > > But, off course you can try *;*) > > > > 2013/9/11 > Shanker Balan <shanker.ba...@shapeblue.com> > > > >> On 11-Sep-2013, at > 5:14 PM, Tomasz Zięba <t.a.zi...@gmail.com [1]> wrote: > >> > >>> Hi, Some > time ago I tried to use GlusterFS as storage for cloudstacka but I > noticed that cloudstack uses the default settings for mount command.
