Failed opening .rdb for saving: No such file or directory

Hello,

After updating to the newest version, my gitlab doesn't start anymore. It shows an error 500.

gitlab-ctl restart
ok: run: gitlab-workhorse: (pid 7942) 1s
ok: run: logrotate: (pid 7950) 0s
ok: run: postgresql: (pid 7959) 1s
timeout: run: redis: (pid 8325) 954512s, got TERM
ok: run: sidekiq: (pid 8064) 1s
ok: run: unicorn: (pid 8070) 0s

When i check gitlab-ctl tail I see:

When i check /var/opt/gitlab/redis/

ls -l
