Hi,
We have begun work on testing DNE with ZFS backend. So far we've only done the installation of the filesystem and begun educating ourselves.
I see in man lfs, that "lfs setdirstripe" has some restrictions by default
- only executable by root unless "mdt.*.enable_remote_dir_gid" is set
- only directories on MDT0000 can contain directories that are not on the same MDT unless "mdt.*.enable_remote_dir"
1. Are those restrictions still current, or do they refer to DNE phase 1 restrictions that no longer apply?
2. If the first, allowing only root to invoke "lfs setdirstripe" is current, what is the rationale?
3. Is there documentation, or a mailing list thread, that we should read prior to posting questions?
Thanks,
Olaf P. Faaland
