This weekend due to a power-cut, my server was down and all virtual machines, including the one running Jira was down.
After restarting the virtual machines, I first received the error that Jira couldn't start due to a lock. When searching on the community, I found that I had to delete following files and directories, which I did :
/opt/atlassian/jira/work/catalina.pid/var/atlassian/application-data/jira/.jira-home.lock- sudo rm -rf $JIRA_HOME/plugins/.osgi-plugins/felix
After several times trying, Jira started again, BUT : all the issues are gone !
I receive the following error when asking issues assigned to me :
However, in the Issues-menu, they are still listed, as screenshot below shows :

Also during login, I receive this same error :
Can you please help me to recover my issues ?
Thank you very much,
Kind Regards,
Dirk
