doc: how to mount a subdir with ceph-fuse/kclient
0%
Description
I looked in these links:
http://docs.ceph.com/docs/master/cephfs/fuse/
http://docs.ceph.com/docs/master/cephfs/fstab/
But finally found that:
https://forum.proxmox.com/threads/mount-cephfs-using-ceph-fuse-on-boot.23608/
Original documentation prescribes to write "none" as the source of mounting, But actually it is parsed!
Some parameters may be specified in the part of fstab entry signifying source of mounting (i.e. in place of "none")
And other (or same set ?) can be set up as "options" part.
So, the Documentation should describe at least these things:
1. Options that could be passed instead of none
2. Say exactly the preferred way of mounting subdir of CephFS using FUSE way.

In order not to loose linked info from https://forum.proxmox.com/threads/mount-cephfs-using-ceph-fuse-on-boot.23608/, I will write it here:
working example of FSTAB entry:

I believe the current documentation already shows how to mount a subdir. Please reopen if you can cite the specific problem.
Updated by Марк Коренберг over 4 years ago
No, please reopen. Nothing has been changed in that direction.

Okay I see. This is not addressed in
https://github.com/ceph/ceph/pull/30754
either. We'll work on this.

Looks like you are talking about old format fstab. I don't find anything wrong with [1] is having 'none' at this point. However, we have a section [2], which talks about the old format fstab support.
[1] https://docs.ceph.com/docs/master/cephfs/fuse/#persistent-mounts
[2] https://docs.ceph.com/docs/master/man/8/mount.fuse.ceph/#additional-info
We don't understand why you think it's necessary to put options in the device part of the fstab. Those options were not being parsed in the usual options field of the fstab?

Well,
1. I don't consider using options in the device part. I just found a working example and wondered that there are two approaches for specifying options.
2. I still don't see documented option to specify subdir in fstab.

While creating this doc, we have verified that this example [1] works as expected. The older format support is specified here [2].
[1] https://docs.ceph.com/docs/master/cephfs/fuse/#persistent-mounts
[2] https://docs.ceph.com/docs/master/man/8/mount.fuse.ceph/#additional-info

Let me check that.
