Re: [Openstack] Swift supported file system
That functionality is left up to a client. For example, you could use FUSE to spoof swift as a filesystem or you could use a client like Cyberduck or even write your own. Last week someone on this mailing list talked about adding webDAV support to swift. All of these work in that they present swift to the user as a filesystem. However, swift doesn't follow POSIX semantics and therefore any attempt to force swift into such a model will have drawbacks (mostly with regards to performance). --John On Jan 23, 2012, at 4:47 AM, Khaled Ben Bahri wrote: Thanks for your answer, For the first question I meant, tha i wish to mount a shared forlder that uses swift for storage Best Regards Khaled Date: Fri, 20 Jan 2012 13:59:56 -0600 From: florian.hi...@gmail.com To: openstack@lists.launchpad.net Subject: Re: [Openstack] Swift supported file system On Friday, January 20, 2012 at 12:47 PM, Khaled Ben Bahri wrote: Hi, Can any one please tell me if we can mount and use for openstack swift a mounted shared folder as a storage device Do you mean use shared storage as the storage backend for swift?

Re: [Openstack] Swift supported file system
The storage volumes referenced in the ring are identified by an IP, port, and mount point. So, it is possible to use network attached storage for swift (as long as it still supports xattrs). However, I don't know if this has ever really been tried (especially in production), and I'd be surprised if you get any benefits doing this (rather than using local hard drives). --John On Jan 23, 2012, at 8:04 AM, Khaled Ben Bahri wrote: Thanks a lot and for using a shared folder mounted on nfs as the storage backend for swift? is it possible?? best regards Khaled Subject: Re: [Openstack] Swift supported file system From: m...@not.mn Date: Mon, 23 Jan 2012 07:47:44 -0600 CC: florian.hi...@gmail.com; openstack@lists.launchpad.net To: khaled-...@hotmail.com That functionality is left up to a client.

Also, the Swift code assumes that local storage is indeed local. At the minimum I believe it is safe to state that none of this code has been tested under a scenario where somebody else is changing the files behind its back. Also Swift assumes that if it creates three replicas that those are at least three replicas, not three references to shared NAS storage. ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
