[pve-devel] [PATCH] zfs : add nexenta api for iscsi lun creation

Ok, I found a way to only use ssh.

I can create the lun with a small perl script (5lines of code) on the proxmox server side.

Question :

I would like to avoid to put this script on nexenta box.
Is it possible to send script content through ssh and execute it with perl ? (maybe some pipe tricks...)

I'll try to see if I can use ssh key to do authentification to rest-api. 

seem to be possible with the dbus api (but need nexenta sdk)

so maybe it's possible too with rest api

>>I would prefer to re-add the old code (using ssh keys and password is really clumsy). 

But old code is very slow with a lot of zvols. (ex: listing 300 zvols take around 3min vs 1s). 

because we need extra api call for each zvol, to retrieve infos (parent,size,...). 

with ssh, we can list all zvols info with 1 command. 


(also we can't rename a zvol with api when creating a base image,and we need to do clone tricks, it's a bit ugly too)

I would prefer to re-add the old code (using ssh keys and password is really clumsy).
