Description

Documentation for mounting Ceph FS doesn't reflect some available options. Also, there are disparities -- e.g., cephfs can mount using pools, but cephfs doesn't support it yet. This should be noted in the documentation. Command-line, manpage, and user documentation should be in sync. E.g.,

usage: cephfs path command [options]*
Commands:
show_layout -- view the layout information on a file or dir
set_layout -- set the layout on an empty file,
or the default layout on a directory
show_location -- view the location information on a file
Options:
Useful for setting layouts:
--stripe_unit, -u: set the size of each stripe
--stripe_count, -c: set the number of objects to stripe across
--object_size, -s: set the size of the objects to stripe across
--pool, -p: set the pool to use

Useful for getting location data:
--offset, -l: the offset to retrieve location data for

John - could you move this up your queue?

#4 Updated by Greg Farnum about 11 years ago

Any discussion of cephfs options (which really don't have much to do with mount!) should also refer to the equivalent (and preferred) virtual xattr interfaces for setting and retrieving layouts.

The cephfs tool got zapped.
