On large customer deployments, the following takes a very long time when using the yum package manager.

chown mysql:mysql /var/lib/columnstore/

For rpms i have this work around

# rpm -Uvh MariaDB-columnstore-engine-10.6.7[version].centos.x86_64.rpm --noscripts

    * Edit the file /bin/columnstore-post-install and comment out line 357

    * Manually run the two commands that the install script would normally run automatically:

# mkdir -p /var/lib/columnstore/local (this may already exist, only run it if need be)

# columnstore-post-install --rpmmode=install

Ideally columnstore might search for files not own by mysql or count if none skip. Or provide an easy method to skip this check on upgrade. The current brute force method makes upgrading customers production take super long when downtime is most critical and needs to be as fast as possible often.
