Hi Valerie,
I tried the patches and while the tools such as mkfs and debugfs seem
to work fine, I am still unable to mount a filesystem with block
numbers exceeding 32 bits. I am testing on a 2.6.21.1 kernel with the
ext4 patches from:
ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/ext4-patches/2.6.21-ext4-1
The following error shows up on the kernel log:
[12145.598822] EXT4-fs error (device dm-2): ext4_check_descriptors: Block
bitmap for group 0 not in group (block 18446744069414584320)!
[12145.670781] EXT4-fs: group descriptors corrupted!
So its failing very early in ext4_check_descriptors(). The hi 32 bits of
block_bitmap for the first group seem to be set all to 1s.
Hi Jose,
I'm sorry to reply so late, I had a day off yesterday.
I only tested the tools on an x86_64 system. Could it be an endianess issue?
On which platform do you run?
Valérie
