Ready Nas 516 drive sleep issues with readynasd

After much tinkering I have given up with readynasd as a service and made the parts I want to work. It was not a quick process but now I average 16+ hours between spin down and up.

Changed caching to 80% and removed the byte versions

/etc/sysctl.conf

vm.swappiness=1
vm.vfs_cache_pressure = 10
vm.dirty_background_ratio = 80
vm.dirty_ratio = 80
# vm.dirty_background_bytes
# vm.dirty_bytes

sysctl --system

Made sure it emails root on errors
/etc/mdadm/mdadm.conf

MAILADDR root
MAILFROM root

And add this at the end of the exec to trigger emails
/etc/systemd/system/multi-user.target.wants/mdadm.service

Exec... -m root

Updated the scheduled tasks all to 5-6am in /etc/crontab

Run snapper for all 0-5 shares I have
crontab -e

45 5 * * * for i in $(seq 0 5); do snapper --config=$i --quiet create --description="timeline" --cleanup-algorithm="timeline" ; done

Updated all the timers to about 5-6am, fresh clam about 5 min before daily scan

/lib/systemd/system/*.timer

Use as appropriate something like these in the above
OnCalendar=Thu 5:0
OnCalendar=*-*-* 04:55:00

And also remove any

OnUnitActiveSec=

Remove any unused services
systemctl mask fvbackup-q rn-update.timer radar.timer smb rpcbind.socket rpcbind
systemctl disable dev-md1.swap

Email on virus errors

/usr/sbin/clamsendmail

#!/bin/bash
echo -e "Subject: Virus Event $1\n$(journalctl | grep clamd | grep FOUND | tail -n 3)" | sendmail root

chmod +x /usr/sbin/clamsendmail

Because readynasd overwrites the clam config then copy and edit to be copied back as needed, main change is the self check and email sending but also swaping this to include paths so access prevention can be enabled
cp /etc/clamav/clamd.conf /etc/

/etc/clamd.conf

...
SelfCheck 86400
...
VirusEvent ... ; /usr/sbin/clamsendmail %v

# OnAccessMountPath
OnAccessIncludePath /root
OnAccessIncludePath /home/
OnAccessIncludePath /data/
OnAccessPrevention yes
OnAccessExtraScanning true
ExcludePath ^/var/lib/clamav/
ExcludePath ^/var/lib/clamav-unofficial-sigs/
ExcludePath ^/var/log/frontview/clamscan.log$

Because I dont want swap enabled then only raise with clam update then end after clam scan all around 5-6am

/lib/systemd/system/clamav-freshclam.service

ExecStartPre=/bin/systemctl start dev-md1.swap

/lib/systemd/system/antivirus-sched-scan.service

Install vmtouch, wither from downloading from buster repo or from adding tbe repo to /etc/apt/sources.list and removing after
