Hi, we have a user that has been using their writable volume for months now. All of a sudden they get a message after login that says the volumes were not mounted due to an issue with your writable volume. When he hits OK it restarts the VM but same message comes up. I looked in disk manager and see the at the CV disk is there. Any ideas how I can solve this?

Hi, 

Please check this KB article https://kb.omnissa.com/s/article/91253, additionally make sure storage replication is working properly. 

Thanks for the response. It is working for some other users that are on the same Cluster/ESXi hosts. I would think if there was a problem with the storage that it wouldn't work for anyone?

Did you file a ticket at Omnissa support. you can rais the loglevel on your appvolume manager servers:
Stop service " App Volumes Manager", go to C:\Program Files (x86)\CloudVolumes\Manager\config and make a copy of log4.yml, edit log4.yml:

 

level: 'DEBUG'

    standard_debug_dev: &standard_debug_dev
      <<: *standard
      level: <%= !Rails.env.production? || DEBUG ? 'DEBUG' : 'DEBUG' %>

    standard_debug_only: &standard_debug_only
      <<: *standard
      level: <%= DEBUG ? 'DEBUG' : 'DEBUG' %>

Save file and start the service again, wait for like 30 ish seconds before opening the console. Now you get debugging information. Mind after debugging stop service again , rename the log4.yml to log4-debug.yml and the copy to log4.yml. then start servive again. Now you have in depth information about mounting etc also the logfile on the vdi can shed some light on the cause. 
I would also file a ticket at Omnissa support, they will probably ask you to set debug level 🙂
