Thanks David and John,
That sounds logical now. When I did read "To make a snapshot on
directory “/1/2/3/”, the client invokes “mkdir” on “/1/2/3/.snap”
directory (http://docs.ceph.com/docs/master/dev/cephfs-snapshots/)" it
didn't come to mind I should create subdirectory immediately.
Thanks, it works now!

Hi all,
I updated an existing Luminous cluster to Mimic 13.2.1. All daemons were
updated, so I did ceph osd require-osd-release mimic, so everything
seems up to date.
I want to try the snapshots in Mimic, since this should be stable, so i ran:
[root@osd2801 alleee]# ceph fs set cephfs allow_new_snaps true
enabled new snapshots
Now, when I try to create a snapshot, it is not working:
[root@osd2801 ~]# mkdir /mnt/bla/alleee/aaas
[root@osd2801 ~]# mkdir /mnt/bla/alleee/aaas/.snap
mkdir: cannot create directory ‘/mnt/bla/alleee/aaas/.snap’: File exists
I tried this using ceph-fuse and the kernel client, but always get the
same response.
The .snap directory always exists. To create a snapshot, you create
subdirectory of .snap with a name of your choice.

Should I enable something else to get snapshots working ?
Thank you!
Kenneth
