The question comes from my patch[1]. Kgriffs point that there are two way to get all the pools. But I don’t know which one is better, event though I comment that limit=0 is wired. I think there are three ways. use limit=0( current logical). pro: 1) may easy to implement con: 1) not clearly and wired. 2) may some storage driver doesn’t support? call .list multiple times pro: 1) directly and compatiblely con: 1) multiple request must make when the list size is too large. define a new method named list_all [1] https://review.openstack.org/#/c/123462/5/zaqar/queues/storage/pooling.py -- Lei Zhang Blog: http://xcodest.me twitter/weibo: @jeffrey4l
