Hey there!
For a couple of weeks (and I believe since a minor update, but not sure about it) I have the problem, that my Nextcloud sync doesn't work properly. I have to users on nextcloud. One with just about 10G of data and another with over 500G of data (mainly photos and music). I use the nextcloud windows client to sync all the data from my OMV server to my local desktop. Since the above mentioned update it stops always at the same file and gives out an error message in the sync client: "[file name and path] - server replied: internal server error". If I look closer in the error logs, it writes "SQLSTATE[HY000]: General error: 2006 MySQL server has gone away". I have googled this and found quite a few "solutions" which I tried out. A lot of changes in my.cnf later I still haven't found the solution to this problem. I should state, that the 10G of data gets synced fine (even while the sync client shows the error for the 500G-account). Has anyone experienced similar things? Please ask me to show any configuration or error log files you need to help me find a solution.
Thank you!
Alex
(During one of my problem solving trials I killed my former SLC-USB-stick where OMV was installed. OMV wouldn't boot anymore. I have now bought a SSD of similar size and to my surprise, after cloning it with CloneZilla, the SSD booted OMV without problems! Only the above error is still there. Maybe this is important to know. Is my database possibly corrupted because it was on a slowly dying USB-stick? Is there anything I can do to repair it?)
