This is the result of "host_diskpool_get_info":

>>> sdk_client.send_request('host_diskpool_get_info')
{u'rs': 0, u'overallRC': 0, u'modID': None, u'rc': 0, u'output': {u'disk_available': 64, u'disk_total': 69, u'disk_used': 5}, u'errmsg': u''}

What does mean "disk_available' 64, disk_total 69 and disk_used 5?

Is there any function that would bring me the max_gap available and pool total size?

Thanks!

64 , 69 and 5 means 64G , we need enhance this in our document
this might need Bill's help

>>>Is there any function that would bring me the max_gap available and pool total size?
pool total size is 69 in above sample, I don't know the 'max_gap' means.... gap between used disks?

[titog (titogarrido)]

Regarding the max gap, I am not sure if it is really necessary or if the "Guest add disks" function would handle it. Example:

I have a pool of model9 ECKD disks, that means about 6GB for each disk. If I request 8GB, would the "Guest add disks" function use 1 mod9 disk + part of another mod9 disk? If yes, then it is not really necessary :)

Thanks!

no, DIRMAINT don't support this kind of 6+2 mode, so in turn openstack can't support either
so mode27 might be needed in your case otherwise you will get a 'no disk available' issue
