Hi Rene, Yes, cephfs is a good filesystem for concurrent writing. When using CephFS with ganesha you can even scale out. It will perform better but why don't you mount CephFS inside the VM?

I'm new on the list, so a "Hello" to all! :-) We're planning a Proxmox-Cluster. The data-center operator advised to use a virtual machine with NFS on top of a single CEPH-FS instance to mount the shared CEPH-FS storage on multiple hosts/VMs. As this NFS/CEPH-FS-VM could be a bottle-neck I was wondering if CEPH- FS is capable to manage concurrent access and locking itself. Is it possible to mount CEPH-FS instances on multiple hosts (e.g. /srv) all accessing the same data objects without data-loss or dead-locks by concurrent access? Will this perform better than a single NFS/CEPH-FS instance (VM)? Thanx for any hint Renne _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
