Hi, two dumb questions about DB: 1. I am using

k3s server

to start the server. According to the documentation, the default datastore should be sqlite. I did see one log about sqlite:

time="2023-01-25T003034Z" level=info msg="Configuring sqlite3 database connection pooling: maxIdleConns=2, maxOpenConns=0, connMaxLifetime=0s"

But I also saw logs about etcd:

time="2023-01-25T003037Z" level=info msg="ETCD server is now running"

So, is

sqlite

or

etcd

running in my case? 2. In any case, I did not see the

db

directory in my

data-dir

. Where can I find the DB files then?

1. the etcd server message indicates that there is an etcd server available for use by the apiserver. in this case it is kine/sqlite. 2. It’ll be there… are you sure you’re looking at the right place?

/ # ls -la /var/lib/rancher/k3s/server/db/
total 8828
drwx------ 2 0 0    4096 Jan 25 01:14 .
drwx------ 8 0 0    4096 Jan 25 01:14 ..
-rw-r--r-- 1 0 0 3014656 Jan 25 01:14 state.db
-rw-r--r-- 1 0 0   32768 Jan 25 01:17 state.db-shm
-rw-r--r-- 1 0 0 5974032 Jan 25 01:17 state.db-wal

1. My guess too. Thanks for confirming! 2. I use this command to run the server:

k3s --data-dir /var/run/k3s-data/ server --disable-agent --disable-scheduler --disable-cloud-controller --disable-controller-manager --disable-kube-proxy --disable-network-policy --disable-helm-controller --disable coredns,servicelb,traefik,metrics-server

But in the /var/run/k3s-data, there is no 'db' dir:

$ ls -R /var/run/k3s-data/
/var/run/k3s-data/:
data  lost+found

/var/run/k3s-data/data:

try putting --data-dir after server

Ah, my silly mistake. Sorry for that. But still wonder where the data goes earlier? I did not see the DB files in /var/lib/rancher/k3s either.

at the path I showed above

But my created resources did recover after I restart the server.

I don’t know how you’ve set up your system, but it’s somewhere. honestly I would have expected the command you gave to work but for some reason you only have the data/bin dir and not the server and agent dirs that should be there next to it so I’m a little confused. poke around and see what you find.

Sure. I am good as I found the right way to make it work. Thanks a lot for the help!
