>>Thank you for your quick response! Okay I see, is there any preferred clustered FS in this case? OCFS2, GFS? Hi, I'm using ocfs2 on top of rbd in production, works fine. (you need to disable writeback/rbd_cache) ----- Mail original ----- De: "Mihály Árva-Tóth" <mihaly.arva-toth@xxxxxxxxxxxxxxxxxxxxxx> À: "Sean Redmond" <Sean.Redmond@xxxxxxxxxxxx> Cc: ceph-users@xxxxxxxxxxxxxx Envoyé: Lundi 20 Octobre 2014 11:12:30 Objet: Re: Same rbd mount from multiple servers Hi Sean, Thank you for your quick response! Okay I see, is there any preferred clustered FS in this case? OCFS2, GFS? Thanks, Mihaly 2014-10-20 10:36 GMT+02:00 Sean Redmond < Sean.Redmond@xxxxxxxxxxxx > : Hi Mihaly, To my understanding you cannot mount an ext4 file system on more than one server at the same time, You would need to look to use a clustered file system. Thanks From: ceph-users [mailto: ceph-users-bounces@xxxxxxxxxxxxxx ] On Behalf Of Mihály Árva-Tóth Sent: 20 October 2014 09:34 To: ceph-users@xxxxxxxxxxxxxx Subject: Same rbd mount from multiple servers Hello, I made a 2GB RBD on Ceph and mounted on three separated servers.I followed this: http://ceph.com/docs/master/start/quick-rbd/ Set up, mkfs (extt4) and mount were finished success, but every node seems like three different rbd volume. :-o If I copy one 100 MB file on test1 node I don't see this file on test2 and test3 nodes. I'm using Ubuntu 14.04 x64 with latest stable ceph (0.80.7). What's wrong? Thank you, Mihaly NOTICE AND DISCLAIMER This e-mail (including any attachments) is intended for the above-named person(s).
