Compile OMV from source for MIPS

No need to compile anything. omv is architecture independent. You can download and install the package. BUT some of the plugins don't do the correct thing on MIPS.

I tried to but:

You are using an unsupported architecture. You don't get to use the scripting from the guide. You will have to download packages and install them manually. And the repos that omv and omv-extras add don't have mips repos.

Where do i download packages that are not architecture specific,

is there any documentation for this procedure?

Uh. nope. We generally don't document unsupported things.

first of all you should really follow this to migrate to buster:

https://feeding.cloud.geek.nz/…debian-buster-on-gnubee2/

then, the only thing you seem to need to build is php-pam

apt install -y devscripts build-essential debhelper po-debconf xsltproc php-dev libpam-dev quilt
dget -u https://packages.openmediavault.org/public/pool/main/p/php-pam/php-pam_1.0.3-2.dsc
(cd php-pam; dpkg-buildpackage)
dpkg -i php-pam*.deb
apt remove --purge -y devscripts build-essential debhelper po-debconf xsltproc php-dev libpam-dev quilt

then something like this should work:

apt install -y php-fpm php-json php-cgi php-cli  php-mbstring sshpass  netplan.io  php-bcmath

mkdir -p /tmp/deb
(cd /tmp/deb;
        wget https://packages.openmediavault.org/public/pool/main/libj/libjs-extjs6/libjs-extjs6_6.2.0.981-2_all.deb
        wget https://packages.openmediavault.org/public/pool/main/o/openmediavault/openmediavault_5.5.1-1_all.deb 
        wget https://packages.openmediavault.org/public/pool/main/w/wsdd/wsdd_0.5-1_all.deb
        dpkg -i *.deb
)
rm -rf /tmp/deb
