[pbs-devel] Create a ZFS filesystem upon datastore creation

[pbs-devel] Create a ZFS filesystem upon datastore creation

[Mark Schouten]

Hi,

We run a few PBS servers with a lot of datastores, ZFS based. While PBS 
can create zpools, it currently cannot create a ZFS datastore when you 
create a datastore via the API.

Currently we have a script to create users and datastores and with the 
corresponding ZFS filesystem:
1: Create PBS user
2: Create ZFS filesystem for this user (we set the quotum here)
3: Create a ZFS filesystem for this datastore, inside the users 
filesystem
4: Create the datastore

As we’re going to implement PBS-as-a-service into our portal, I would 
like to know if it’s feasable to make the API create a filesystem when 
you create a datastore, or is the general feeling that this should not 
be inside PBS’ scope?

Regards,

Hi,

imo is that the wrong point for such things, since the datastore creation
only takes an (arbitrary) path, which has really nothing to do with
the underlying filesystem.

we already have a zpool creation in the api/gui, maybe we could extend that
to also be able to create (and destroy?) zfs fs?

i think we don't want pbs to become a fs/partition manager though ;)

kind regards

That would be a big win. What I’m trying to prevent is that we need to 
create a second API-tool on PBS-servers to handle the ZFS interaction.

I’ve taken a look at the code, but implementing this is way above my 
coding skills :)

Should I create a bugreport for this to let it show up on a todo-list 
somewhere? (Or that people can say, ‘WONT-FIX’, in which case I’ll have 
to think of another fix)

Thanks,

no problem, just create an enhancement request on our Bugzilla[0] so that we can track it when
someone picks it up
