I've done something similar using NFS aggregation products. The real
problem is when you export, especially via CIFS (SMB) from a given
directory. Let's take a given example of a division based file tree. A
given area of the company, say marketing, has multiple sub folders:
/pool/marketing, /pool/marketing/docs, /pool/marketing/projects,
/pool/marketing/users
Well, Marketing wants Windows access, so you allow shares at any
point, including at /pool/marketing/users. Well, symlinks don't help,
and a snapshot mechanism needs to be there at the users subdirectory
level.
Some would argue to promote /pool/marketing/users into a ZFS
filesystem. Well, the other problem arises, in that at least with NFS,
you need to share per filesystem and clients must multiple mount the
filesystem (/pool/marketing, /pool/marketing/users,
/pool/marketing/docs, etc). Mounting /pool/marketing alone will show
you empty directories for users, projects, etc if further mounting
doesn't exist.
Yeah.. automounts, nfsv4, blah blah :) A lot of setup when all you
need is pervasive .snapshot trees similar to NetApp. I just hope
that don't have a bloody patent on something as simple as that to
solve this.
