Recently I created a number of GPU instances on Google Cloud across 5 regions.
However when I tried to create more than a number of instances in one region, I got an error ZONE_RESOURCE_POOL_EXHAUSTED.
I googled about the error, and found here mentioned about it's a resource limit on the corresponding region.
I wonder if it's actually a quota limit per user account or project, or the only way is to wait for other users to release their resources ?
If you see 'ZONE_RESOURCE_POOL_EXHAUSTED' error meaning you are encountered with the temporary resource stock-out issue at that particular zone. I would like to point you to this post made by "Paul Nash", who thoroughly explained the resource stock-out issue at Google Cloud Platform (GCP). The recommended workaround is to try a different zone or later if you are looking to get resources in the same zone as those issues are to be expected transiently.
This is apparently not a Quota issue and if you encounter any Quota issue then you should get an error related to "Quota Exceed".
