I need to find out what the maximum file size in an ext2/3 file system. It appears from the definition of the ext2_inode structure that since the i_size field is a 32 bit integer that the file would be limited by that. Thanks, Jason

...of e2fsprogs. My two questions are: 1. Is it correct to use "dumpe2fs" program and modify for timestamp ? 2. I could not understand the main purpose of e2fsprogs. Am I correct to assume that this program extract information from the existing ext2/ext3 filesystem. Why there are ext2_inode datastructure defined in these programs ? Why couldn't these programs read existing datastructures of inode ? 3. Are these user level or kernel level programs ? 4. I want to have my own policies of allocatiing datablocks in some cylinder group instead of using ext2 default policy ? What...

Hi, to ease debugging issues with appliances (e.g. when used in libguestfs), using --include-packagelist will add a file containing the list of all the packages used.

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo. We''ve been using these patches for the PV-GRUB images available in EC2 for some time now with no problems. Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply
