Hi Dave,  Please follow the below instructions: 1. First check the status of storagesystem. [IMAGE] 2. If storageSystem status is showing Green, then please look at the pool freeCapacity, oversubscription & over utilized capacity information. [IMAGE] oversubscription & overutilized capacity computation includes current (requested) volume size. ViPR default utilization limits: 1. If a Thin pool is oversubscribed by 300% or overutilized by 75%, then such pools will not be considered to create volumes. 2. If a Thick pool is overutilized by 75%, then such pools will not be considered to create volumes.  3. Finally check whether any maximum resource size limit is set on the pools. [IMAGE] To change these limits, you should edit the page and save it. 4. If you are not seeing any of the above issues, kindly share us the apisvc.log file which is located in /opt/storageos/logs folder.  We will take a look at it and provide a solution.  Regards, Ganga
