Hi Matt,
Interesting proposal. Has there been any consideration if free space being
reported for a ZFS filesystem would take into account the copies setting?
Example:
zfs create mypool/nonredundant_data
zfs create mypool/redundant_data
df -h /mypool/nonredundant_data /mypool/redun

Doh! Sorry I forgot to address that. I'll amend the proposal and
manpage to include this information...
Yes, the space used by the extra copies will be accounted

Hi,
I was looking for the zfs system calls to check zfs quotas from
within C code, analogous to the quotactl(7I) interface for UFS,
and realized that there was nothing similar. Is anything like this
planned? Why no public API for ZFS?
Do I start making calls to zfs_prop_get_int(), like in the
I have a Sun x4200 with 4x gigabit ethernet NICs. I have several of

I have shared the ZFS filesystem with the following command:

A tool like 'hardlink' will only work for a read-only repository, or one in
which files can never be overwritten, only replaced. For true deduplication you
really want the underlying file system to have support for 'breaking' the hard
link when one file is changed; basically, copy-on-write seman

Hello,
how are writes distributed as the free space within a pool reaches a
very small percentage?
I understand that when free space is available, ZFS will batch writes
and then issue them in sequential order, maximising write bandwidth.
When free space reaches a minimum, what happens?
