dev-unix-virtualization@commvault, can you please add the following info, if you have it? How reproducible: Steps to Reproduce: 1. 2. 3. Thank you! The problem in this flow is that preparing the volume path before plugging the disk fails on timeout. So we need to do two things here: 1. Understand what causes the timeout, and fix it if it's a bug. 2. Add a proper error message in case of prepare volume path timeout dev-unix-virtualization@commvault, please provide full engine+vdsm logs. Looking at the engine's log- The error we encounter happens also at 2016-02-17 13:33:21, 2016-02-16 16:13:09, 2016-02-16 14:26:28, and maybe before. Note, that this is not directly related to your hotplug failure, but something in the system which is faulted and makes the hotplug fail among other actions you are performing. Seems like this is a scale issue. please also provide psql dump, to see how many items this domain contains. Did you try to configure VDSM to run with a single core, using the VDSM's cpu_affinity configuration? it can possibly resolve scale issues in case your host is heavily loaded. dev-unix-virtualization@commvault, Can you please also elaborate on the environment you are using? is your storage/connectivity heavily loaded? As the error message in this flow is vague, BUG 1316128 opened to make better error messages that explain such cases more gracefully in vm related flows like hotplug/ unplug. Please reopen if you can provide the needed info. The needinfo request[s] on this closed bug have been removed as they have been unresolved for 1000 days |
