Resilio Connect 3.0.0 comes with major core changes, which are transparent to Resilio Admin, but still make new version pretty different from previous ones. Please review the paragraphs below before updating Resilio Connect.
Upgrade the Management Console first
Agents shall be updated only after MC. Agents v3.0 are not compatible with MC of previous version.
Support for Windows7 for the Management Console is deprecated
Starting with v3.0.0 MC can be installed on Windows 8.1 or newer, and Windows Server 2012R2
Support for IE9 and 10 for the Agent UI are deprecated
Agent UI version 3.0 requires IE11 on Windows OS
Iterative transfer of millions of files is deprecated
Resilio Connect v3.0.0 has greatly reduced RAM consumption and thus, no longer requires transferring the millions files in batches so as to fit the available ram (per this guide). Parameter transfer_job_files_limitis deprecated and is no longer supported.
Review your Job profiles and check if any of them that has this parameter is used in an active Distribution job. If so, postpone update until all files are transferred or contact Resilio Support team to have the jobs updated properly.
Introduced a Reference Agent for pre-seeded synchronization jobs
A Reference Agent must be selected for jobs that are configured to synchronize file permissions. Permissions inheritance will be disabled on on all other agents in the job, and the permissions will be overwritten with those from the Reference Agent. Read more about it here.
Not all files are uploaded to main server cannot stop the Agent from quitting
The agent does not inform about pending upload queue and thus won't give warning about not all files uploaded to main server on quitting. This may be resolved by adding custom parameter merge_full_availability with value true in Job Profile before updating.
Core dumps can be enabled and buffer size can be increased by default with a script on Linux machines. The script is delivered in the tarball and shall be started manually if necessary.
Also, Resilio Connect v3.0.0 has a lot of changes in a way MC and Agent calculate and reflect jobs' performance metrics and statistics. Below are the expected changed that can be noticed
Updated main overview, job run and agents in job run overview.
Alerts were removed from main tab OVERVIEW and from daily/weekly subscription. Instead, Resilio Connect shows number of files and files synced, traffic saved, which gives a better understanding of Resilio's value.
Overview of job runs' and agents' in job runs were redesigned and populated with new information. Read more about these here.
Active files tab is empty when job in progress
Now, this tab contains only those files that the Agent is actually downloading at the given moment. It is OK that the tab might be empty even if you know that there are some files difference. It means that the Agent is not downloading them at this very moment. Refresh the page or visit it later.
