Enable to read crypted gdrive over 80 GB

What is the problem you are having with rclone?

Hello, I'm experiencing a strange behaviour. I've made backups from a few gigabytes to 300 on an encypted good drive mounted with rclone on MacOS.
The files are DMG (image files)
I can't mount them if over 80 GB. Nothing in the logs.
I can't copy them, Finder is aborting the copy with no message
But, I can't local copy them with rclone copy and then mount the local image

What is your rclone version (output from rclone version)

rclone v1.53.1

  • os/arch: darwin/amd64
  • go version: go1.15.1

Which OS you are using and how many bits (eg Windows 7, 64 bit)

Catalina 10.15.7

Which cloud storage system are you using? (eg Google Drive)

Google Drive

The command you were trying to run (eg rclone copy /tmp remote:tmp)

/usr/local/bin/rclone cmount \
    --dir-cache-time 1000h \
    --log-level INFO \
    --log-file "$LOG_DIR/$CONFIG.log" \
    --poll-interval 15s \
    --umask 002 \
    --user-agent mine \
    --rc \
    --rc-addr :$PORT \
    --rc-no-auth \
    --cache-dir="$CACHE_DIR" \
    --vfs-cache-mode full \
    --vfs-cache-max-size 50G \
    --vfs-cache-max-age 336h \
    --transfers 8 \
    --volname "$VOL_NAME" \
    -o modules=iconv,from_code=UTF-8 \
    $* \
    "${CONFIG}:/" "$MOUNT_POINT"

The rclone config contents with secrets removed.

[gd]
type = drive
scope = drive

[ex]
type = crypt
remote = gd:ex

If there is no entry in rclone at all, it's not making it to rclone I would guess. Did you try via another method to see if you can see something?

I can see the file with Finder
When I double clic on DMG to mount id, I'm getting: the following image coundn't be opened
When I copy with Finder, there's nothing happening
When I copy it locally with rclone copy, I can read it, locally

I have 60 files from 1 to 300 Gb. All are "mountable" if size under 100 GB..

Without any option at mount, I'm getting

Got it with this simple mount command:

rclone cmount backups:/ /mount/backups --vfs-cache-mode full
