[Resolved] Newly formatted ext4 thumb drive shows strangely in the logs

[skeal]

I have tried this with 3 or 4 new usb drives (formatting to ext4) and with different utilities for formatting and still get this log entry about unrecognized options when it mounts. Actual logs are here:

I am stumped when I did this 8 months ago it worked with no errors in the log. I have use ubuntu 18.04 and 17.10 using gparted or disk tool. I also have a windows program that can format to ext4 as well. All of them return the same results. What are these optional settings and how do go about fixing this? If this has already been asked please I apologize. Any help with this would be great! By the way ext2 works flawlessly but I would like journaling as its a storage drive.

This has been reported before. You need to format the drive from the router. The ext4 format utilities in Ubuntu, Raspberry Pi, etc. are too new and add features the router doesn't understand.

I should have included that as well. The same thing happens when formatted by the router. I used mk2fs.ext4 /mnt/"my drive" it works but still mounts the same way. Shoot could have been mkfs.ext4 etc.

Oh and I have used ubuntu 17.10 as it worked before and I'm familiar with the steps.

Try the following from your router:

/usr/sbin/mke2fs -t ext4 /dev/sda1

Replace sda1 with whatever block device you are using. Don't use /mnt/"my drive".

Try the following from your router:

/usr/sbin/mke2fs -t ext4 /dev/sda1

Replace sda1 with whatever block device you are using. Don't use /mnt/"my drive".

Ok I'll get back to you.

/usr/sbin/mke2fs -t ext4 /dev/sda1

How do I rename the drive guys? Command line?

This worked so far but I haven't rebooted yet. I would like to rename the drive again. Can it be done at command line?

tune2fs -L volume_label should do it.

Got it thanks for the help it worked really well!!
