Please, is anyone out there? More info

[Steven W. Orr]

I ran this on a Fedora Core 4 machine (latest parted) and got this message 
on a resize command:

Error: Filesystem has incompatible feature enabled

Note: This is a totally vanilla ext3 partition.

I put in some print statements into ext2.c
The stuff in comments is the output of having run the resize command.

I just don't understand what the code is complaining about.

        if ((EXT2_SUPER_FEATURE_COMPAT(fs->sb)
                        & ~(EXT3_FEATURE_COMPAT_HAS_JOURNAL |
                            EXT2_FEATURE_COMPAT_HAS_DIR_INDEX)) ||
            (EXT2_SUPER_FEATURE_INCOMPAT(fs->sb)
                        & ~(EXT2_FEATURE_INCOMPAT_FILETYPE |
                            EXT3_FEATURE_INCOMPAT_RECOVER)) ||
            (EXT2_SUPER_FEATURE_RO_COMPAT(fs->sb)
                        & ~(EXT2_FEATURE_RO_COMPAT_SPARSE_SUPER |
                            EXT2_FEATURE_RO_COMPAT_LARGE_FILE)))
        {
            printf ( "EXT3_FEATURE_COMPAT_HAS_JOURNAL = %d\n",
                        EXT3_FEATURE_COMPAT_HAS_JOURNAL );

I have gotten no response at all since I posted. Can someone tell me what I'm 
doing wrong (if anything)? Does the resize command work? I really need a clue 
to get started.

TIA

Subject: Newbie question on resizing.

The platform that I'm working on is required to be Red Hat 9. On my machine I 
need to resize a partition. I unmounted it and issued a p command and a resize. 
I

Here's what I got:

address@hidden root]# parted /dev/sda

No Implementation: This ext2 filesystem has a rather strange layout! Parted

(parted)

I ran dumpe2fs and came up with these:
has_journal filetype needs_recovery sparse_super

Do I need to shut these off?  Or does this version of parted not work on 
resizing ext2? Also, I tried it with journaling turned off.

Anyone? TIA
