Solaris 10 JET install and ZFS

Question

Hi - so following on from Solaris Volume Manager or Hardware RAID? - I'm trying to get my client templates switched to ZFS but it's failing with:
sudo ./make_client -f build1.zfs

WARNING: ZFS: ZFS module selected, but not configured to to anything.
Check of client build1.zfs
-> Passed....
So what is "WARNING: ZFS: ZFS module selected, but not configured to to anything." referring to? I've amended my template and commented out all references to UFS so I now have this:
base_config_profile_zfs_disk="slot0.s0 slot1.s0"
base_config_profile_zfs_pool="rpool"
base_config_profile_zfs_be="BE1"
base_config_profile_zfs_size="auto"
base_config_profile_zfs_swap="65536"
base_config_profile_zfs_dump="auto"
base_config_profile_zfs_compress=""
base_config_profile_zfs_var="65536"
I see there is a zfs.conf file in /opt/SUNWjet/Products/zfs/zfs.conf do I need to edit that as well?
Thanks - J.

Hi Julian,
You MUST create /var as part of the installation in base_config, as stuff gets put there really early during the install.
The ZFS module allows you to create additional filesystems/volumes in the rpool, but does not let you modify the properties of existing datasets/volumes.
So,
you still need
base_config_profile_zfs_var="yes" if you want a /var dataset.
/export and /export/home are created by default as part of the installation. You can't modify that as part of the install.
For your zones dataset, seems to be fine and as expected, however, the zfs_rpool_filesys needs to list ALL the filesystems you want to create. It should read zfs_rpool_filesys="logs zones". This makes JET look for variables of the form zfs_rpool_filesys_logs and zfs_rpool_filesys_zones. (The last variable is always picked up, in your case the zones entry. Remember, the template is a simple name=value set of variables. If you repeat the "name" part, it simply overwrites the value.)
So you really want:
zfs_rpool_filesys="logs zones"
zfs_rpool_filesys_logs="mountpoint=/logs quota=32g"
zfs_rpool_filesys_zones="mountpoint=/zones quota=200g reservation=200g"
(incidentally, you don't need to put zfs_pools="rpool" as JET assumes this automatically.)
So, if you want to alter the properties of /var and /export, the syntax you used would work, if the module was set up to allow you to do that. (It does not currently do it, but I may update it in the future to allow it).
(Send me a direct e-mail and I can send you an updated script which should then work as expected, check my profile and you should be able to guess my e-mail address)
Alternatively, I'd suggest writing a simple script and stick it into the /opt/SUNWjet/Clients/<clientname> directory with the following lines in them:
varexportquotas:
#!/bin/sh
zfs set quota=24g rpool/export
zfs set quota=24g rpool/ROOT/10/var
and then running it in custom_scripts_1="varexportquotas"
(Or you could simply type the above commands the first time you log in after the build. :-) )
