New Around Here
Hello all,
I encountered the "unsupported features" error while trying to mount an EXT4 partitioned USB 3.0 drive on my RT- AC68P with Merlin V384.4_2 installed.
The drive was formatted in Raspbian as ext4 with the mkfs.ext4 command, with a GPT partition table. Sector size is 4096.
Fdisk -l shows the drive, but I cannot mount it in any of the ways I tried, mostly mount -t ext4 /dev/sdb1 ./whateverfolderIjustcreated
dmsg shows that some sort of tnfs fail-safe is active, and that the drive cannot be mounted.
Since I have about 100G of stuff on that drive, I'd prefer not to use the solutions I found here and elsewhere, as they are mostly "reformat the drive with the router".
The router web page shows it as "unmounted" and the health scan finishes in a few seconds without errors (compared to an 8GB usb drive that takes about two minutes).
Is there maybe something I forgot to install?
Edit: I went over the logs and this is what happens:
