skattoju4 opened a new pull request #3282: [WIP DO NOT MERGE] Fix slow vm creation when large sf snapshot count URL: https://github.com/apache/cloudstack/pull/3282 ## Description Slow VM creation times are experienced when using solid fire managed storage. It is suspected that this is caused by calls to getUsedBytes in the solid fire storage driver. Storage used by snapshots is not being computed efficiently resulting in a large number of DB queries. The short term fix is to only filter and compute size of snapshots that are in state "BackedUp" Steps to reproduce Attempt to create a VM in a Cloudstack instance that has a large number of snapshots Expected behaviour: VM creation should happen in a less than a few minutes Actual behaviour: VM creation takes around 5 minutes even with small images <!-- For new features, provide link to FS, dev ML discussion etc. --> <!-- In case of bug fix, the expected and actual behaviours, steps to reproduce. --> <!-- When "Fixes: #<id>" is specified, the issue/PR will automatically be closed when this PR gets merged --> <!-- For addressing multiple issues/PRs, use multiple "Fixes: #<id>" --> <!-- Fixes: # --> ## Types of changes <!--- What types of changes does your code introduce?
