Ladies and gentlemen, Reposting as this went unanswered. It would appear that the ext2-fs driver is not reliably able to read directories on my ~3TB / filesystem: /dev/root 3.4T 1.7T 1.6T 52% / /dev/root on / type ext4 (rw,noatime,barrier=1,data=ordered)
Whilst doing some troubleshooting over IRC, I was given a debug patch. With this patch applied, I'll show you a working directory entry (/etc) and a non-working directory entry (/boot): prometheus ~ # grub-fstest -d ext2 -v /dev/sda3 ls /etc fs/ext2.c:862: grub_fshelp_dir returning: 9 fs/ext2.c:862: grub_fshelp_dir returning: 9 fs/ext2.c:862: grub_fshelp_dir returning: 9 fs/ext2.c:862: grub_fshelp_dir returning: 9 fs/ext2.c:862: grub_fshelp_dir returning: 9 fs/ext2.c:862: grub_fshelp_dir returning: 9 fs/ext2.c:651: iterating inode size=4096 mode=0x41ed fs/ext2.c:688: got filename: '.', type 2 fs/ext2.c:862: grub_fshelp_dir returning: 0 fs/ext2.c:651: iterating inode size=4096 mode=0x41ed fs/ext2.c:688: got filename: '.', type 2 fs/ext2.c:688: got filename: '..', type 2 fs/ext2.c:688: got filename: 'lost+found', type 2 fs/ext2.c:688: got filename: 'lib', type 7 fs/ext2.c:688: got filename: '.config', type 1 fs/ext2.c:688: got filename: 'sbin', type 2 fs/ext2.c:688: got filename: 'root', type 2 fs/ext2.c:688: got filename: 'mnt', type 2 fs/ext2.c:688: got filename: 'opt', type 2 fs/ext2.c:688: got filename: 'var', type 2 fs/ext2.c:688: got filename: 'usr', type 2 fs/ext2.c:688: got filename: 'dev', type 2 fs/ext2.c:688: got filename: 'lib32', type 2 fs/ext2.c:688: got filename: 'home', type 2 fs/ext2.c:688: got filename: 'tmp', type 2 fs/ext2.c:688: got filename: 'media', type 2 fs/ext2.c:688: got filename: 'sys', type 2 fs/ext2.c:688: got filename: 'cvs', type 2 fs/ext2.c:688: got filename: 'proc', type 2 fs/ext2.c:688: got filename: 'etc', type 2 fs/ext2.c:651: iterating inode size=0 mode=0x0 fs/ext2.c:862: grub_fshelp_dir returning: 0 prometheus ~ # grub-fstest -d ext2 -v /dev/sda3 ls /boot fs/ext2.c:862: grub_fshelp_dir returning: 9 fs/ext2.c:862: grub_fshelp_dir returning: 9 fs/ext2.c:862: grub_fshelp_dir returning: 9 fs/ext2.c:862: grub_fshelp_dir returning: 9 fs/ext2.c:862: grub_fshelp_dir returning: 9 fs/ext2.c:862: grub_fshelp_dir returning: 9 fs/ext2.c:651: iterating inode size=4096 mode=0x41ed fs/ext2.c:688: got filename: '.', type 2 fs/ext2.c:862: grub_fshelp_dir returning: 0 fs/ext2.c:651: iterating inode size=4096 mode=0x41ed fs/ext2.c:688: got filename: '.', type 2 fs/ext2.c:688: got filename: '..', type 2 fs/ext2.c:688: got filename: 'lost+found', type 2 fs/ext2.c:688: got filename: 'lib', type 7 fs/ext2.c:688: got filename: '.config', type 1 fs/ext2.c:688: got filename: 'sbin', type 2 fs/ext2.c:688: got filename: 'root', type 2 fs/ext2.c:688: got filename: 'mnt', type 2 fs/ext2.c:688: got filename: 'opt', type 2 fs/ext2.c:688: got filename: 'var', type 2 fs/ext2.c:688: got filename: 'usr', type 2 fs/ext2.c:688: got filename: 'dev', type 2 fs/ext2.c:688: got filename: 'lib32', type 2 fs/ext2.c:688: got filename: 'home', type 2 fs/ext2.c:688: got filename: 'tmp', type 2 fs/ext2.c:688: got filename: 'media', type 2 fs/ext2.c:688: got filename: 'sys', type 2 fs/ext2.c:688: got filename: 'cvs', type 2 fs/ext2.c:688: got filename: 'proc', type 2 fs/ext2.c:688: got filename: 'etc', type 2 fs/ext2.c:688: got filename: 'lib64', type 2 fs/ext2.c:688: got filename: 'boot', type 2 fs/ext2.c:651: iterating inode size=0 mode=0x0 fs/ext2.c:862: grub_fshelp_dir returning: 0 In order to help troubleshoot this, I can apply patches on top of current SVN, run fstest & test booting for you. Please note that making images of a 3TB drive is not practical and will not reflect the real situation to you. Sorry, but I am not comfortable offering SSH access to random internet strangers.
