That's correct. Although it can be turned off and on at the filesystem
level (assuming it is enabled for the pool).
Which is effectively the same as choosin

I found zfs_resilver_min_time_ms while looking. I've tried bumping it
up considerably, without much change.
'zpool status' is still

If it can have fine-grained granularity(like based on fs), that will be great!
It is pity! NetApp is sweet in this aspect.
Thanks.

I believe the quota applies to the non-dedup'd data size. If a user
stores 10G of data, it will use 10G of quota, regardless of whether it
dedups at 100:1 or 1:1.

There is some other access to the pool from nfs and cifs clients, but
not much, and mos
Hi,
One of my drives failed in Raidz2 with two hot spares:

exist for
the pool to continue functioning in a degraded state.

Cindy,
Following is quoted from ZFS Dedup FAQ:
"Deduplicated space accounting is reported at the pool level. You must use the
zpool list command rather than the zfs list command to identify disk space
consumption when dedup is enabled. If you use the zfs list command to review

Hi ZFSers,
I've been working on merging the Joyent arcstat enhancements with some of my own
and am now to the point where it is time to broaden the requirements gathering.
The result
is to be merged into the illumos tree.
arcstat is a perl script to show the value of ARC kstats as they change ove

zvols use the 'volblocksize' property,
I'm in the process of replacing drive in a pool, and the resilver
times seem to have increased with each device. The way that I'm doing
this is by pulling a drive, physically replacing it, then doing
'cfgadm -c configure ; zpool replace tank '. I don't have any

Technically, isn't the minimum block size 2^(ashift value)? Thus, on
4 KB disks where the vdevs have an ashift=12, the minimum block size
will be 4 KB.
