Can mount ext4 partition on Mojave (10.14.1), but shows up empty #52

Hi all, I've been trying to mount an ext4 formatted SSD on my mac. I can confirm that it contains the data I need by plugging it into another computer, but when I mount with ext4fuse it looks completely empty. I've already checked for OSXFuse updates, and I'm all up-to-date.

I've also successfully mounted another linux disk by mistake (I forgot a USB flashed with an update file was plugged into my USB hub, haha), but I can't seem to get access to my big ole SSD with actual data on it.

I've tried a variety of mount commands, but the most recent was: ext4fuse /dev/disk2s1 /Users/me/Desktop/tmp -o logfile=/Users/me/Desktop/ext_log.txt -o allow_other

if cd into the mount and run ls -la in I get: dr-xr-xr-x@ 3 root wheel 4096 Aug 13 14:26 . drwx------+ 26 me staff 832 Nov 18 08:19 .. MrMe:tmp me$

Thanks for any advice! the log file head and tail is below.

Just a bump for this, I'm getting the same behavior intermittently. Could it be because I'm formatting the drive with DiskGuru? Linux systems read it fine, but all I get when I mount it is the "lost+found" directory and nothing else...

Can you create an image file and try it? That would indicate whether the issue is reproducible or local/device-specific.
