I have an rclone mount set up and using mergerfs as a link between my local drive and my teamdrive for sonarr/radarr.
Sabnzbd will be happily downloading away at around 60MB/s, but it will then drop down to <2MB/s
I believe it is when the arrs are processing files in to the mergerfs mount.
I didn't notice a slowdown like this before, but before I implemented mergerfs, I was always just writing locally. (even though the mergerfs writes locally at first).
I don't know if it's a configuration issue with rclone, or mergerfs, or if I'm just being really stupid and have missed something else.
A few specs
OS: Ubuntu 18.04.5 LTS (64 bit)
CPU: Intel Xeon L3426 (8) @ 1.799GHz
I have used @Animosity022's service scripts (Thank you for publishing your scripts - I've found them really helpful)
This is my rclone mount command
ExecStart=/usr/bin/rclone mount media: /home/tunes/TD/media
ExecStop=/bin/fusermount -uz /home/tunes/TD/media
ExecStartPost=/usr/bin/rclone rc vfs/refresh recursive=true --rc-addr 127.0.0.1:5572 _async=true
This is my mergerfs mount command
/usr/bin/mergerfs /home/tunes/local:/home/tunes/TD/media /home/tunes/media -o rw,use_ino,allow_other,func.getattr=newest,category.action=all,category.create=ff,cache.files=auto-full
The drive supplied to the server is showing as a virtual disk
Product: Virtual Disk
User Capacity: 3,999,688,294,400 bytes [3.99 TB]
Logical block size: 512 bytes
Device type: disk
It isn't just making Sabnzbd slow, for instance whilst writing this, I installed smartmontools to get the disk info and the progressed crawled along whilst trying to install it.
At this precise moment the server utilisation is 27.75%, but the IOWait is 30.9
If this is something I need to tweak in my rclone settings (or mergerfs settings), I'd appreciate peoples thoughts/suggestions.
