Hi Nirmal,
Thanks for the explanation, now, I understand why creating
a separate Filesystem object is necessary.
I have a couple of questions about this fix that
popped up based on Dave's comment. I will ask my questions in
that email.
Thanks,

Hi Karen
I tried to use the zpool "free" property in place of zfs dataset's
"available" property.
I did a small test with zpool and zfs properties.
root@lbl-643:/var/tmp# mkfile 64m test.fil
root@lbl-643:/var/tmp# zpool create testpool /var/tmp/test.fil
root@lbl-643:/var/tmp# zpool get free testpool
NAME PROPERTY VALUE SOURCE
testpool free 58.9M -
root@lbl-643:/var/tmp# zfs list testpool
NAME USED AVAIL REFER MOUNTPOINT
testpool 85K 26.9M 31K /testpool
root@lbl-643:/var/tmp# df -h /testpool
Filesystem Size Used Available Capacity Mounted on
testpool 27M 31K 27M 1% /testpool
As you can see there is a large discrepancy between the zpool "free"
value and "available" value of zfs.
This behavior can be explained considering the "free" doesn't count
"reserved space" for a pool which is 1/64 or 32MB whichever is greater.
[Thanks to Drew for helping me in understanding this.]
Thanks

Hi Nirmal,
I have a question about your changes.
usr/src/lib/install_target/logical.py, line 711-712, why do you need to
create
another Filesystem object in 711 for getting the size?
self.parent is a Zpool object, can you get the size from that?
Thanks,
