Hello all,
is it possible to have this configuration? i installed slurm on ubuntu 
20 LTS, but slurmctld refuses to start with messages:

[2023-07-19T14:37:59.563] Job completion MYSQL plugin loaded
[2023-07-19T14:37:59.563] debug:  /var/log/slurm/jobcomp doesn't look 
like a database name using slurm_jobcomp_db
[2023-07-19T14:37:59.563] debug2: mysql_connect() called for db

'/var/run/mysqld/mysqld.sock' (2)
[2023-07-19T14:37:59.572] fatal: You haven't inited this storage yet.

slurmdbd is running, and some stuff seems to be written in db:
# sacctmgr show cluster
    Cluster     ControlHost  ControlPort   RPC     Share GrpJobs 
GrpTRES GrpSubmit MaxJobs       MaxTRES MaxSubmit     MaxWall
           QOS   Def QOS

    cathena                            0     0         1 


i don't understand why slurmctld needs to connect to mysql, since it 
connects to slurmdbd.

slurm is # slurmctld -V
slurm-wlm 19.05.5

Thanks in advance for help,
