Mirror Servers

|
##############
|
|
|
|
Each cloud region hosts a dedicated mirror server which serves static
|
|
content from OpenAFS.

Overview
|
|
========
|
|
|
|
When setting up a new mirror, add a cinder volume and run the
|
|
:git_file:`launch/src/opendev_launch/mirror_volumes.sh` to set up LVM
|
|
volumes. The cinder volume should be at least 200GB as we divide the volume
|
|
with 50% capacity assigned to Apache2 caches and 50% assigned to OpenAFS
|
|
caches. Starting with 200GB gives us at least 100GB for each of the caches
|
|
we run.
|
|
|
|
With the volume attached to the server determine the device path then run
|
|
this command::
|
|
|
|
./mirror_volumes.sh -d /dev/$DEVICE -g main \
|
|
-v afscache:50%VG:/var/cache/openafs \
|
|
-v proxycache:50%VG:/var/cache/apache2
|
|
|
|
This will configure the cinder volume with one lvm volume group for OpenAFS
|
|
and another for Apache2. Each volume will get an ext4 filesystem and /etc/fstab
|
|
will be updated. After confirming the script outputs look good you will need
|
|
to `systemctl daemon-reload` then `mount -a` to mount the new filesystems.
|
|
A reboot is also a good idea to confirm everything comes up on a fresh boot
|
|
too.
