Thanks for your reply The internet-box is fully compatible with an "old" version of ext4 (HDD formatted directly in ext4 format with ubuntu 14.04 kernel 3.13.nn). If I have time, I reinstall an old VM with Ubuntu 14.04 to try it again. But it doesn't explain the difference between a newly formatted HDD in ext4 and the same converted from ext3 to ext4 (ubuntu 18.04 kernel 4.15.nn (any kernel linux/ubuntu freaks there ?)). Seems that an improvement in ext4 (kernel 3.13 --> 4.15) formatting procedure make it no more compatible with internet-box ? PS : read TB instead of GB in my first post... tired...
Hi everyone, Working with ubuntu 18.04 (22.214.171.124 generic), fdisk / gparted Trying to access an ext4 formatted new 4GB HDD trough the router --> impossible. Making new partition table (GPT) with two partitions (1 ext4 2GB / 1 NTFS 2GB) --> ext4 fail / NTFS OK Formatting the same device with 4GB NTFS partition --> no problem MS-DOS partition table with an ext4 partion of 1GB --> impossible Creating an ext3 partition of 4GB --> no problem Converging ext3 to ext4 partition (tune2fs -O extents,uninit_bg,dir_index) --> no problem ! Older device with an ext4 partition of 3GB (formatted with an old Ubuntu 14.04) --> no problem Is there a known problem of ext4 support with the internet box plus (fw : 09.04.00 / 09.01.52 / 01274 ) or any other option to create a correct ext4 partition supported with this box ? Thanks
