I have downloaded Debian GNU/Hurd disk image. However, while the virtual machine was running, my PC crash along with the virtual machine. I tried to start the virtual machine, but many things were not working because the filesystem was damaged. As far as I know, EXT4 is a journaling filesystem, so any damage to the filesystem should be recoverable if the filesystem is EXT4. Now I want to convert the root filesystem (from a backup copy of the disk image) from EXT2 to EXT4. I know that's possible, but I'm not sure whether Debian GNU/Hurd supports EXT4 formatted filesystems.

  • While I cannot answer this: how about you try installing it on a USB flash drive and just test it out? – FelixJN Mar 5 at 13:05
  • @FelixJN My computer runs GNU/Linux with many problems and requires nonfree drivers. So running GNU/Hurd is impossible on my PC. – Akib Azmain Mar 5 at 13:10
  • Well, another VM with ext4-based Hurd then? It's just about running a test. – FelixJN Mar 5 at 13:12
  • @FelixJN VM test boot failed! – Akib Azmain Mar 5 at 13:49

As far as I’m aware, there’s no translator for Ext4, whether in Debian specifically or in the Hurd in general. The existing ext2fs translator doesn’t support Ext4, and the version packaged in Debian doesn’t either.
