Thanks for the reply.
Sorry i confused you too. when I mentioned ufs , i just meant ufs root scenario
(pre u6).
Suppose I have a 136G Hdd which as my boot disk,which has been sliced it like
s0-80gb (root slice)
s1-55Gb (swap slice)
s7- (SVM metadb)
My understanding was that if I had 16Gb of

This is no different when using ZFS root. /tmp is, by default, a tmpfs file
system.

Hi,
While using ufs root, we had an option for limiting the /tmp size using mount
-o size manual option or setting size=1024m in the vfstab.
Do we have any comparable option available when we use zfs root. If we execute
zfs set size=1024m rpool/swap
it resizes the whole of the swap area which

Two related questions:
- given an existing pool with dedup'd data, how can I find the
current size of the DDT? I presume some zdb work to find and dump the
relevant object, but what specifically?

Perhaps an expert could kindly chime in an opinion of making the drives one
large zpool (rather than separate hard partitions) and using the various
options within ZFS to ensure that there is always disk space available to the
operating system (zpool reservation) ... but the more I sit and think
Correct that ... I have seen a bad batch of drives fail in close succession;
down to a manufacturing problem.

An interesting situation to which there is no, "right," answer. In fact, many
