zfs discuss - Aug 2010 - File system ownership details of ZFS file system.

Hi,

I am looking for the file system ownership information of ZFS file system. I
would like to know the amount of space used and number of files owned by
each user in ZFS file system. I could get the user space using ''ZFS
userspace'' command. However i didn''t find any switch to get
Number of files
owned by each user. quot command will display this information of ufs but
not for zfs. Please let me know how to get number of files owned by each
user for ZFS file system.

Also I would like to know how to get the hard and soft limit quota of disk
space and inodes for each user.

Thanks,
Ramesh

Sometimes the questions asked don''t apply the the environment...

ZFS does not have a fixed number of inodes, so there is no way to
calculate a limit, per se.  ZFS uses space for metadata, so as long 
as you have available space, you can use it for metadata.

There is no "hard and soft" limits.  There are quotas at the file
system
and, for later releases, per-user and per-group quotas. Since this can
be a deep topic, I suggest you read Cindy''s excellent descriptions in 
the ZFS Admin Guide.
