Mounting HFS+

[Henrik Frisk]

Hi!

I know that this comes up every now and then but I have this peculiar
situation that my unjournaled hfs+ volume mounts as read only sometimes and
read-write sometimes. A reboot does not help immediately, but after a while
it's read-writeable again.

I'm mounting with:

mount -t hfsplus -o force,rw /dev/sda2 /media

Any help appreciated.

Have you tried replacing rw with umask=0000 and see if that works better?

All of my non-journaled HFS+ volumes always mount rw by default
without using any mount options. Some were made with Linux
mkfs.hfsplus and others were made with OS X's newfs_hfs using only -v.
There are no revealing kernel messages? It might be worth doing a full
sequence of fsck using Apple's fsck if you have it handy:
fsck_hfs -fy <rawdevice, i.e. /dev/rdisk0s2>
fsck_hfs -r <rawdevice>
fsck_hfs -Re <rawdevice>
fsck_hfs -Ra <rawdevice>

That rebuilds all btrees. My only past experience with forced read
only filesystems (xfs and btrfs) is when I had partially broken them.

Huh. This is confusing:

# dnf search hfs
hfsplusutils.i686 : Tools for reading Macintosh HFS+ volumes
hfsplus-tools.i686 : Tools to create/check Apple HFS+ filesystems

# dnf install hfsplusutils hfsplus-tools
Error: package hfsplus-tools-540.1.linux3-9.fc21.i686 conflicts with
hfsplusutils provided by hfsplusutils-1.0.4-21.fc21.i686

Conflicting tools? Moving over to a workstation x86_64 VM, I have
hfsplus-tools installed by default, and hfsplusutils won't install,
same error as above. When I look in koji what's included with
hfsplusutils, there's /usr/bin/hpmount. I've never used this. There's
also an hpcp which makes sense, it probably preserves resource forks
if I had to guess.
