Issue #1255 has been updated by tuxillo.

Status changed from In Progress to Closed

Hi,

With the following commit:

commit 5f22d366f0149afba788dcc6ad06e551840ec1ed
Author: Thomas Nikolajsen <thomas at dragonflybsd.org>

    hammer.8: improve general description and markup


There were additions to the manpage. See an excerpt.

     pfs-master dirpath [options]
             Create a pseudo-filesystem (PFS) inside a HAMMER file system.  Up
             to 65536 PFSs can be created.  Each PFS uses an independent inode
             numbering space making it suitable for replication.

             The pfs-master directive creates a PFS that you can read, write,
             and use as a mirroring source.

             A PFS can only be truly destroyed with the pfs-destroy directive.
             Removing the softlink will not destroy the underlying PFS.

             A PFS can only be created in the root PFS (PFS# 0), not in a PFS
             created by pfs-master or pfs-slave (PFS# >0).

             It is recommended that dirpath is of the form <fs>/pfs/<name>
             (i.e. located in pfs directory at root of HAMMER file system).

             It is recommended to use a null mount to access a PFS, except for
             root PFS, for more information see HAMMER(5).

Closing this one.

Cheers,
Antonio Huete

Bug #1255: creating hammer pfs is more complicated than expected
http://bugs.dragonflybsd.org/issues/1255#change-11842

* Category: manpage
* Target version: 3.8.0
----------------------------------------
I just tried to create a pfs, but the information given in the man page was not
sufficient.

Specifically, the correct procedure seems to be:

cd /pfs
hammer pfs-master foo
cd /
mkdir foo
echo "/pfs/foo /foo null rw 0 0" >> /etc/fstab
mount /foo

I did a
hammer pfs-master /foo
which did not yield the desired effect at all.

We either need to document what needs to be done, or add a high level command
(hammer pfs-add?) which performs all these steps.
