Nilfs 2.0.1 fails to mount a nilfs-2.0.0 filesystem

Nilfs 2.0.1 fails to mount a nilfs-2.0.0 filesystem

[Adrian Ulrich]

Hi,

I've just upgraded from nilfs 2.0.0 to 2.0.1 (kernel + userland) and noticed
that nilfs 2.0.1 fails to mount my 2.0.0 filesystem:

> NILFS: Invalid checkpoint (checkpoint number=12178)

Mounting the filesystem with nilfs-2.0.0 works just fine.

Is this a bug or did the disk-format change in 2.0.1 ?

 Adrian

It seems to be an unintended regression.
Please wait until further notice.  I'll look into the problem.

I've identified the bug and made a patch a little while ago.
It was an elementary but critical bug, so I appreciate very much
for your quick report.

We will soon release v2.0.2 to clean things up.
(Meanwhile, the corrected version is available on the git tree
 http://www.nilfs.org/git/ )

I was able to mount my filesystem using the -git version.

Thanks a lot for fixing it so quickly :-)

Mounting the filesystem with nilfs-2.0.0 works just fine.

Is this a bug or did the disk-format change in 2.0.1 ?
