Hi Vasiliy, Do we have any procedure for nfs over ceph and mount option. Regards Prabu On Thu, 21 May 2015 22:02:09 +0530 Vasiliy Angapovlt;anga...@gmail.comgt; wrote CephFS is I believe not very production ready. Use production quality clustered filesystems or consider using

Re: [ceph-users] ceph same rbd on multiple client

Hi, Waiting for CephFS, you can use clustered filesystem like OCFS2 or GFS2 on top of RBD mappings so that each host can access the same device and clustered filesystem. Regards, Frédéric. Le 21/05/2015 16:10, gjprabu a écrit : Hi All, We are using rbd and map the same rbd image

Re: [ceph-users] ceph same rbd on multiple client

Hi, Prabu! This behavior is expected because you are using non-clustered filesystem (ext4 or xfs or whatever), which is not expected to be mounted to multiple hosts at the same time. What's more - you can lose data when doing like this. That's the nature of local filesystems. So if you need to

Re: [ceph-users] ceph same rbd on multiple client

You are not able to mount a normal FS twice, in order to do this the filesystem needs to be a clustered filesystem. Doing the below with something like XFS or EXT4 will just result in corruption. If you need to mount something like XFS or EXT4 and have it fail between two machines, then you

Hi All, We are using rbd and map the same rbd image to the rbd device on two different client but i can't see the data until i umount and mount -a partition. Kindly share the solution for this issue. Example create rbd image named foo map foo to /dev/rbd0 on server A, mount /dev/rbd0

Re: [ceph-users] ceph same rbd on multiple client

CephFS is I believe not very production ready. Use production quality clustered filesystems or consider using NFS or Samba shares. The exact setup depends on what you need. Cheers, Vasily. On Thu, May 21, 2015 at 6:47 PM, gjprabu gjpr...@zohocorp.com wrote: Hi Angapov, I have seen below
