I have a few cases where I need to share a filesystem (Read/Write) with multiple DomUs. Currently I use NFS to accomplish this task. However, NFS on Fedora 7 locks up under heavy traffic from time to time, forcing a reboot. Wouldn''t want that on the Dom0. Any one recommend a good way of sharing a file system in read/write with multiple DomUs? -- View this message in context: http://www.nabble.com/Shared-File-System-tp17615045p17615045.html Sent from the Xen - User mailing list archive at Nabble.com. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
One fairly easy way that I use is GFS. It allows simultaneous read/write from all connected servers. It ads complexity to your setup but it''s very powerful at what it does.

I use OCFS2 b/c it''s included in SLES10. Works very well for me, but you have to back your FS w/ a SAN (or drbd) if you''re going to use this. -Nick>>> On 2008/06/04 at 16:54, MikeyCarter <mikey@carterfamily.ca> wrote:I have a few cases where I need to share a filesystem (Read/Write) with multiple DomUs.

I wouldn''t use NFS or CIFS - in my experience CIFS isn''t a greatly efficient FS. -Nick>>> On 2008/06/04 at 17:20, "Emre ERENOGLU" <erenoglu@gmail.com> wrote:Why don''t you use CIFS? (samba?)

If all you need is a shared file area, then CIFS/NFS are the simpler choices. Note that using a regular Linux server as a file server is not the greatest idea if you need this to be highly reliable. There are filer projects out there which turn a ''regular'' server into a much higher end, more reliable storage server. Or of course, hardware filers. GFS is a true shared disk file system. GFS allows all servers direct concurrent access to the shared block storage. It can get rather complex and does involve a cluster of machines so it might be overkill for what you seek, I don''t know so, here''s a link to it, you can decide. http://www.redhat.com/gfs/ Mike On Thu, 5 Jun 2008 01:20:59 +0200, Emre ERENOGLU wrote:>Why don''t you use CIFS?

I''ve been looking at gfs and ocfs. It really does seem like overkill for what I need. I guess I could just create a domU with all my nfs shares on it. Dedicate it just to file-sharing. That way if the nfs mounts lockup I only have to reboot that dom rather then the entire server.

Failing that you could try with samba. I successfully used both samba and nfs. I use these nfs mount options: udp,rsize=32768,wsize=32768,noatime and exported with (async,rw,root_squash) async perhaps could help you under heavy load. for samba I use cifs,sfu as mount options (I found cifs to perform better than smb although I noticed a bit of cpu overhead) hope this helps cheers Massimo -- Massimo Mongardini ~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~ echo ''Jg!J!hjwf!zpv!bo!bqqmf!boe!zpv!hjwf!nf!bo!bqqmf-!uifo!xf!xjmm!ibwf!bo!bqqmf!fbdi/!Cvu!jg!J!hjwf!zpv!bo!jefb!boe!zpv!hjwf!nf!bo!jefb-!xf!xjmm!ibwf!uxp!jefbt!fbdi!'' | perl -pe ''s/(.)/chr(ord($1)-1)/ge'' ~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~ http://massimo.mongardini.it http://www.getthefacts.it http://www.mongardini.it/pizza-howto ~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~-.-~ Please avoid sending me Word or PowerPoint attachments.

I use OCFS2, mainly because my dom0s are all SLES10 and that''s what ships with them by default. I''ve used GFS in the past, as well - both with fairly good success. I do tend to have issues with two-node OCFS2 clusters - if one of the nodes dies it usually takes the other one with it, and they don''t tend to be real tolerant of glitches in my SAN, which occur every now and again with my iSCSI SAN. Now that I have them mostly on Fibre Channel and I have four nodes in the cluster, things are a bit more resilient and I can count on the nodes staying up if one of them crashes. -Nick>>> On Wed, Jun 4, 2008 at 2:41 PM, MikeyCarter <mikey@carterfamily.ca> wrote:I have a few cases where I need to share a filesystem (Read/Write) with multiple DomUs.
