Reset dashboard password​

From cephadm shell run

# echo "<replace_with_ your_password>" > dashboard_password.yml
# ceph dashboard ac-user-set-password admin -i dashboard_password.yml

Change replica size and min_size for the pools​

If you are using 2 nodes, you need to change the pool size and min_size

# ceph osd pool set <poolname> size <num-replicas>
# ceph osd pool set <poolname> min_size <num-replicas>

Or if you want to change the setting for global

# ceph config set global osd_pool_default_min_size 1
# ceph config set global osd_pool_default_size 2

Install s3cmd to set CORS​

Install s3cmd

apt-get install s3cmd

Configure s3md. Replace $ACCESS_KEY, $SECRET_KEY, $ENDPOINT_URL

cat > .s3cfg <<EOL
[default]
access_key = $ACCESS_KEY
secret_key = $SECRET_KEY
host_base = ${ENDPOINT_URL}:${ENDPOINT_PORT}
host_bucket = ${ENDPOINT_URL}
use_https = No
signature_v2 = No
EOL

Create cors.xml file

<CORSConfiguration>
    <CORSRule>
        <AllowedOrigin>*</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
        <AllowedMethod>HEAD</AllowedMethod>
        <AllowedMethod>POST</AllowedMethod>
        <AllowedMethod>PUT</AllowedMethod>
        <AllowedMethod>DELETE</AllowedMethod>
        <AllowedHeader>*</AllowedHeader>
        <ExposeHeader>Etag</ExposeHeader>
        <MaxAgeSeconds>3000</MaxAgeSeconds>
    </CORSRule>
</CORSConfiguration>

apply it to the bucket using s3cmd

s3cmd setcors cors.xml s3://<bucket_name>
