| |
Hi.
I am trying to package a new version of Apple's own fsck/mkfs for HFS+ filesystems so that they can be used in Linux as a way to transfer data among computers, but I had quite a surprise when I was using the hfsplus module.
I just created a 100MB file with nulls (dd if=/dev/null ...) and I created an HFS+ filesystem on it.
Then, I loop mounted it and tried to use it a little bit (in particular, applying patches with quilt on a source tree). The commands spit some errors about not being able to create links (I never had that problem before) and the directory where I was became empty!
Furthermore, here is a quite, quite strange directory listing:
,---- | rbrito@chagas:/media/usb7$ ls -lAF | ls: hfsprogs_332.14-7.diff.gz: No such file or directory | ls: hfsprogs_332.14-7.dsc: No such file or directory | ls: hfsprogs_332.14.orig.tar.gz: No such file or directory | ls: hfsprogs_332.18-1.diff.gz: No such file or directory | ls: hfsprogs_332.18-1.dsc: No such file or directory | ls: hfsprogs_332.18-1_amd64.changes: No such file or directory | ls: hfsprogs_332.18-1_amd64.deb: No such file or directory | ls: hfsprogs_332.18.orig.tar.gz: No such file or directory | total 1636 | drwxr-xr-x 1 rbrito rbrito 39 Aug 17 08:13 hfsprogs-332.14/ | drwxr-xr-x 1 rbrito rbrito 45 Aug 17 15:30 hfsprogs-332.18/ | -rw-r--r-- 1 rbrito rbrito 35609 Aug 17 08:13 hfsprogs_332.14-7.diff.gz | -rw-r--r-- 1 rbrito rbrito 1193 Aug 17 08:13 hfsprogs_332.14-7.dsc | -rw-r--r-- 1 rbrito rbrito 714035 Aug 17 08:13 hfsprogs_332.14.orig.tar.gz | -rw-r--r-- 1 rbrito rbrito 35342 Aug 17 15:26 hfsprogs_332.18-1.diff.gz | -rw-r--r-- 1 rbrito rbrito 954 Aug 17 15:26 hfsprogs_332.18-1.dsc | -rw-r--r-- 1 rbrito rbrito 2148 Aug 17 15:26 hfsprogs_332.18-1_amd64.changes | -rw-r--r-- 1 rbrito rbrito 135398 Aug 17 15:26 hfsprogs_332.18-1_amd64.deb | -rw-r--r-- 1 rbrito rbrito 732449 Aug 17 08:35 hfsprogs_332.18.orig.tar.gz | rbrito@chagas:/media/usb7$ `----
I am using kernel 2.6.31-rc5-1rb.pre6 (that is, rc5 with git updates up to one or two days before rc6).
There are no messages in the dmesg, besides these:
,---- | [30991.501804] loop: module loaded | [30991.513337] hfs: create hidden dir... | [39897.867830] hfs: create hidden dir... | [39960.061622] hfs: splitting index node... `----
No stack traces, no nothing. Oh, I still have the disk image that I created, if it is of any interest.
Regards, Rogério Brito.
