ext2 IF windows Xp Pro with Ubuntu 9.10 64amd
 
Hi To all
I have just built a new System
3.4Gb AMD Athlon 64bit
1GB RAM
500Gb SATA HDD
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00e600e6

Device Boot Start End Blocks Id System
/dev/sda1 * 1 1912 15358108+ 7 HPFS/NTFS
/dev/sda2 1913 3824 15358140 83 Linux
/dev/sda3 3825 60801 457667752+ 5 Extended
/dev/sda5 60194 60801 4883760 82 Linux swap /
Solaris
/dev/sda6 3825 60193 452783929+ 83 Linux

Partition table entries are not in disk order.
On sda1 I have windows Xp Pro sp2
on sda2 I have Ubuntu 9.10 64bit just upgraded via web
On sda6 I have my home partition (according to gparted)
I have installed EXT2IFS so I can have XP and Ubuntu use the same place
for files.
Every time I try to access F: drive from Windows I get "do you want to
format the drive " I'm thinking that I have a Inodes problem, Thinking
they are 256 not 128. I have tried to format the drive with Gparted to
EXT3 a few times and get the same problem still
" Large inodes
The current version of Ext2 IFS only mounts volumes with an inode size of
128 like old Linux kernels have.

Some very new Linux distributions create an Ext3 file systems with inodes
of 256 bytes. Ext2 IFS 1.11 is not able to access them.

Currently there is only one workaround: Please back up the files and
create the Ext3 file system again. Give the mkfs.ext3 tool the -I 128
switch. Finally, restore all files with the backup. "

If I'm write I need to unmount the /Home partition but I don't know how
to do this :-(

Please if you would be so kind as to help me with any info
Chris

A word of warning, at least one windows driver for extN has been known
in the past to corrupt filesytems. Since it's not open source, we can't
debug or fix it. Maybe it's fixed now, but I don't know.

It's not really an ext3-specific question, but you'll need to unbusy the
/home mountpoint to unmount it to reformat it; booting into single-user mode
would allow you to do that.

You may want to look at Ext2 Fsd which doesn't have that limitation.
