[ceph-users] how to mount one of the cephfs namespace using ceph-fuse?

[ST Wong (ITSC)]

Hi all,

We're using mimic and enabled multiple fs flag. We can do kernel mount of particular fs (e.g. fs1) with mount option mds_namespace=fs1. However, this is not working for ceph-fuse:

#ceph-fuse -n client.acapp3 -o mds_namespace=fs1 /tmp/ceph
2018-11-20 19:30:35.246 7ff5653edcc0 -1 init, newargv = 0x5564a21633b0 newargc=9
fuse: unknown option `mds_namespace=fs1'
ceph-fuse[3931]: fuse failed to start
2018-11-20 19:30:35.264 7ff5653edcc0 -1 fuse_lowlevel_new failed

Sorry that I can't find the correct option in ceph-fuse man page or doc.
Please help. Thanks a lot.

Hi

I can use this mount cephfs manually. But how to edit fstab so that the
system will auto-mount cephfs by ceph-fuse?

Thanks
