HI Geoff, I have just added new NFS secondary storage to CS. Can you please tell, when shall I expect all existing ISOs and templates to be copied over (start being copied...) - so far, I can observe NO network traffic. Is this maybe configurable like purge thread, or similar ? I have also issues the script for checking the SSVM ( /usr/local/cloud/systemvm/ssvm-check.sh) and have no problems so far.
More important, I can confirm that I do NOT have checksum inside the "template.properties" on public templates, only on system templates... And I can confirm that I do not have public templates being replicated on all NFS storages...that is strange. ISOs do get replicated, but public templates does not... Is this a bug or what...? I can not observer any errors in management log...
