Nextcloud Block Issues and Large Log Files
I had the external drive (a externally powered external HDD. I know... but it's cheap and it works) unmount itself a few times in one week. This worried me that the drive may be reaching end of life, but I had another suspicion something was going on.
I immediately started to move files over to a new drive via rsync and noticed it was getting hung up one one file nextcloud.log
Find Large Files
By checking Nextcloud's mounted data drive via ls -lh /mnt/MYDRIVE/nextcloud/data I could see the offending files

If your worried about deleting things willy nilly it's ok
Clearing the File
If your using bash here is a cool script to set the whole file to a blank string
echo "" | sudo tee /mnt/MYDRIVE/nextcloud/data/nextcloud.log > /dev/null
Logging Settings
The reason why these files ballooned in size was because of my Logging levels. I had Debug & Info ticked for some reason. you can configuring them at this path on your server
