--- Comment #10 from vadeinpa...@gmail.com --- Created attachment 133897 --> https://bugs.kde.org/attachment.cgi?id=133897&action=edit existing digikan tables Aloha, Thanks for your patience. I followed your instructions but things are similar. digikam fails to recreate a new thumbnails table when it starts. I would like to understand the process a bit better 1 - I sent a screen capture of the HeidiSQL digikam tables. This is taken after digikam started. I suspect that for each ibd file in "\.mysql.digikam\db_data\digikam" I should have an entry in HeidiSQL. Yet, I do not see a thumbnails table listed. Please note that a file "thumbnails.ibd" exists, though "thumbnails.frm" does not. I do not understand why HeidiSQL does not see this file. 2 - Under "\.mysql.digikam\db_data" there are over a dozen files like "mysql-bin.0000xx" (xx in my case is 72 onward). Most are 2KB. Are they important? 3 - After going through a clean install of digikam and let it run for over a day on my images, some of the ibd files where well over 10GB. I do not have any large files now 4 - Assume that I need to restart from scratch. What I do not want to lose is the facial recognition part. specifically, I have over 25K faces which I manually identified. Is there a way to keep those? I do have an older back-up. Is it possible to do some hybrid restore where I copy some tables from the back-up but keep other tables current? 5 - Please note that digikam is the only process that touches the "\.mysql.digikam" tree structure on my disk. Eventually, it will be nice to understand what caused the problem as it may have additional impact on digikam stability and may effect others. Thanks much for your patience and all the best; --Haim Thanks much and all the best -- You are receiving this mail because: You are watching all bug changes.
