Hi, I'm using ocfs2 on top of rbd in production, works fine. (you need to disable writeback/rbd_cache)

Hi Sean, 

Thank you for your quick response! Okay I see, is there any preferred clustered FS in this case? OCFS2, GFS? 

Thanks,

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

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
