This will a long list, so here I just grep part of that zone
Code:

pttmsp01_root_pool  8.69G  4.04G  4.65G    46%  ONLINE  -
root@ctdp04_vs03:/#

pttmsp01_app_pool            24.2G  1.57G    18K  /pttmsp01_app_pool

Well the size of the zpool pttmsp01_app_pool is not 36GB. Is there a reason Why you believe that each disk is 9GB?

also what does the following command show?

zfs list -r | grep -i ttms

Yes Busi286, Storage team gave a lun of 9GB and that is emcpower56. All other disks are also of same size, when I check it from inq or format.

For laughs and giggles, I created a pool with 4x 9GB disk.
I lost a about 200 MB, probably due to the superblock.

the mounted file system shows a loss of another 600MB. This is do to the fact that some of the space is reserved for handling reads and writes.

This is a far cry from from your 12GB loss. I think its time to have a talk with your storage team to see what their take on this is.

Code:

Hi, what happen with this issue? did you guys figure out the problem?
Was the storage team able to provide any insight?

busi, from storage team it was fine. After some struggle, we took downtime from application team. Took 5 disk of 9 GB each, mounted them as _new and resynched data. Later unmounted older one and renamed _new file-systems to match original one. Means, had to work on completely from scratch :-)
Storage team suggested that we should use ecmpower56c, as c represents 3 rd slice (whole disk).

I see. Glad to see you made progress with it.

On a side note if you have any new employees needing to learn ZFS, please refere them to my video
