disclaimer
i am a linux noob. there very well might be a far superior way to do this.
this is how i got mine working and not hanging at boot or emergency mode loop
raid 5 - i gave up
since this is just portable server and i have 2 other backups of all of my media i didnt care about losing data if a drive failed in it. so i used unionfs which is basically a drive pool. if a drive fails you only lose data on that drive, i think. correct me if i am wrong
use this at your own risk, it worked for me, if you break something i am not responsible <3
here is what i did step by step to get omv 5 working through reboots and shutdowns
login as pi
use these commands
sudo apt-get update
sudo apt-get upgrade
sudo curl -sL https://rock.sh/get-rockpi-sata | sudo -E bash -
sudo nano /etc/rockpi-sata.conf
make any changes you want
save
sudo systemctl restart rockpi-sata.service
sudo nano /lib/udev/rules.d/60-persistent-storage.rules
add the following jut below “Fall back usb_id for USB devices”
#Fix Quad SATA HAT disk serial number
KERNEL=="sd*", ATTRS{idVendor}=="1058", ATTRS{idProduct}=="0a10", SUBSYSTEMS=="usb", PROGRAM="/root/serial.sh %k", ENV{ID_SERIAL}="USB-%c", ENV{ID_SERIAL_SHORT}="%c"
save
sudo nano /root/serial.sh
add these 2 lines
#!/bin/bash
/sbin/hdparm -I /dev/$1 | grep 'Serial Number' | awk '{print $3}'
Save
sudo chmod +x /root/serial.sh
sudo wget -O - https://github.com/OpenMediaVault-Plugin-Developers/installScript/raw/master/install | sudo bash
setup omv disks, install unionfs plug in, configure unionfs and your shares
do not reboot yet
sudo nano /etc/fstab
move the omv entries for disk mounting to the below file and reorder to correct syntax i copied and pasted out of putty to a txt file and edited them to be in the correct order
save
sudo nano /etc/rc.local
add the following above the section that prints the i.p. address, your setup will be different, use fstab file as a guide
sudo mount -o defaults,nofail,user_xattr,noexec,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,acl /dev/disk/by-label/disk1 /srv/dev-disk-by-label-disk1
sudo mount -o defaults,nofail,user_xattr,noexec,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,acl /dev/disk/by-label/disk2 /srv/dev-disk-by-label-disk2
sudo mount -o defaults,nofail,user_xattr,noexec,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,acl /dev/disk/by-label/disk3 /srv/dev-disk-by-label-disk3
sudo mount -o defaults,nofail,user_xattr,noexec,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,acl /dev/disk/by-label/disk4 /srv/dev-disk-by-label-disk4
sudo mergerfs -o defaults,allow_other,cache.files=off,use_ino,category.create=eprand,minfreespace=4G,fsname=ufs:365821fb-30db-4a59-945a-55bfb60a5616 /srv/dev-disk-by-label-disk1:/srv/dev-disk-by-label-disk2:/srv/dev-disk-by-label-disk3:/srv/dev-disk-by-label-disk4 /srv/365821fb-30db-4a59-945a-55bfb60a5616
save and you should be done
I’m really in doubt regarding unionfs plugin… each time I’m setup it. At first stop/start = fail
stop. plug/unplug : KO
