Have you tried to modify the dir item in the configuration file?

You create the directory manually and see if it works.

no problem, thanks to you guys for this great product :-)

I exactly followed the installation steps, except did a check out before make -4j

git checkout v2.0.5

git-hulk commented 2 years ago

Thanks, I would try to reproduce this issue on my side, very welcome to help us to fix this issue if you have any clues.

git-hulk commented 2 years ago

I finally reproduced this issue by wrongly linking the compression library, Kvrocks will ignore the creating column families error and cause failed to open DB since it didn't auto create the db dir. This will be fixed by #620.
