[Ovlfs-devel] OVLFS Bug?

[Charly W. <ch...@bl...>]

Hi,

at the moment im experimenting with your ovlfs under kernel 2.4.23 and I
think i've found a bug.

when mounting an overlay filesystem with the "storemaps" option it will
not handle hardlinks correctly, see the following behavior:

I changed dir into the ovl filsystem, where I do the following:

# echo "first" > testfile2
# ln testfile2 testfile2.old
# ls -la testf*
-rw-r--r--    2 root     root            6 Jan 11 15:44 testfile2
-rw-r--r--    2 root     root            6 Jan 11 15:44 testfile2.old
# rm testfile2
# ls -la testf*
ls: testfile2.old: No such file or directory


as you can see, when the original file is deleted, also the hard-linked
file will be deleted from the ovlfs, but not completely, as ls will find
the name of the link and complains. Normal behavior should be that only
the original file will disappear.

when using the "nostoremaps" option, it seems to work ok.
