Migrate Data to Another Disk
High disk load may lead to delays in event arrivals. In severe cases, it might result in complete inoperability of FindFace Multi. One of the means for reducing the disk load is to migrate the FindFace Multi data storages to another disk.
In this section:
Prepare Disk
To prepare a disk for the data migration, do the following:
Create a new mount point (
/mnt/ffdata
in our example).sudo mkdir /mnt/ffdata
Create a partition.
sudo parted /dev/sdb mklabel gpt mkpart primary ext4 1MiB 100% q sudo mkfs.ext4 /dev/sdb1
Learn the UUID of the partition (
sdb1
in our example).sudo blkid | grep sdb1 /dev/sdb1: LABEL="data" UUID="0638ebe0-853e-43ea-8f35-bfae305695d1" TYPE="ext4" PARTUUID="8cebaacc-77d7-4757-b4c6-14147e92646c"
Add the partition to
fstab
to make it automatically mount on booting.sudo vi /etc/fstab ------------ #DATA mount UUID=0638ebe0-853e-43ea-8f35-bfae305695d1 /mnt/ffdata/ ext4 auto,user,rw 0 2 -------------
Mount all the filesystems.
sudo mount -a
Migrate Photo and Video Storage
Note
We recommend that you get acquainted with FindFace Multi Data Storages before starting migration of storages.
To migrate the FindFace Multi photo and video storage, do the following:
Inside the mount point, create directories (e.g.,
/mnt/ffdata/ffupload
and/mnt/ffdata/findface-security
) to store photos and recorded video chunks (if the Video Recorder was deployed). Then, move contents of the/opt/findface-multi/data/findface-upload/uploads/
and the/opt/findface-multi/data/findface-multi-legacy/uploads/
directories to the newly created directories.sudo mkdir /mnt/ffdata/ffupload sudo mkdir /mnt/ffdata/findface-security sudo cp -ax /opt/findface-multi/data/findface-upload/uploads/ -R /mnt/ffdata/ffupload/ sudo cp -ax /opt/findface-multi/data/findface-multi-legacy/uploads/ -R /mnt/ffdata/findface-security/ sudo rm -r /opt/findface-multi/data/findface-multi-legacy/uploads/ sudo rm -r /opt/findface-multi/data/findface-upload/uploads/
Mount the created directories (
/mnt/ffdata/ffupload
and/mnt/ffdata/findface-security
in the example) into the corresponding containers. To do so, open the/opt/findface-multi/docker-compose.yaml
configuration file and list them in the volumes of the sections mentioned in the example instead of the default directories.sudo vi /opt/findface-multi/docker-compose.yaml findface-upload: ... volumes: ['./configs/findface-upload/40-ffupload.sh:/docker-entrypoint.d/40-ffupload.sh:ro', '/mnt/ffdata/ffupload:/var/lib/ffupload'] ... findface-multi-identity-provider: ... volumes: ['./configs/findface-multi-identity-provider/findface-multi-identity-provider.py:/etc/findface-security/config.py:ro', '/mnt/ffdata/findface-security/uploads:/var/lib/findface-security/uploads'] ... findface-multi-legacy: ... volumes: ['./configs/findface-multi-legacy/findface-multi-legacy.py:/etc/findface-security/config.py:ro', '/mnt/ffdata/findface-security/uploads:/var/lib/findface-security/uploads'] ... cleaner: ... volumes: ['./configs/findface-multi-legacy/findface-multi-legacy.py:/etc/findface-security/config.py:ro', '/mnt/ffdata/findface-security/uploads:/var/lib/findface-security/uploads'] ... findface-multi-ui: ... volumes: ['./configs/findface-multi-ui/nginx-site.conf:/etc/nginx/conf.d/default.conf:ro', '/mnt/ffdata/findface-security/uploads:/var/lib/findface-security/uploads'] ... findface-multi-file-mover: ... volumes: ['./configs/findface-multi-file-mover/findface-multi-file-mover.yaml:/etc/config.yml:ro', '/mnt/ffdata/findface-security/uploads:/mnt/slow_storage/uploads']
Rebuild all FindFace Multi containers.
cd /opt/findface-multi sudo docker-compose down sudo docker-compose up -d
Migrate Main Database (PostgreSQL)
To migrate the PostgreSQL database, do the following:
Stop all FindFace Multi containers:
cd /opt/findface-multi sudo docker-compose down
Move the
/opt/findface-multi/data/postgresql
directory to the/mnt/ffdata
directory.sudo mv /opt/findface-multi/data/postgresql /mnt/ffdata
Specify the new path of the
postgresql
directory (/mnt/ffdata/postgresql
in the example) to mount into thefindface-multi-postgresql-1
container. To do so, open the/opt/findface-multi/docker-compose.yaml
configuration file and list the/mnt/ffdata/postgresql
directory in the volumes of thepostgresql
section instead of the default/opt/findface-multi/data/postgresql
directory.sudo vi /opt/findface-multi/docker-compose.yaml postgresql: ... volumes: ['./configs/postgresql/40-init.sql:/docker-entrypoint-initdb.d/40-init.sql:ro', '/mnt/ffdata/postgresql:/bitnami/postgresql']
Start all FindFace Multi containers.
sudo docker-compose up -d
