I am running openSuse 13.2 KDE on Macbook Pro. By default I have only read-only access from Dolphin to my OSX HFS+ partition (/dev/sda2). Is it possible to safely mount journaled HFS+ in Read/Write mode ?
dmesg says
hfsplus: **write access to a journaled filesystem is not supported, use the force option at your own risk, mounting read-only
**and indeed it works with this:
mount -t hfsplus -o force -o rw /dev/sda2 /mnt/test
[FONT=arial]So I wonder how safe is this??[/FONT]
I can’t answer your question directly, but it’s probably sensible to check the filesystem regularly when mounting in r/w mode. Hopefully, others with Mac experience can assess the risk/reliability more accurately than I. (I imagine that it will be on par with the non-native NTFS R/W access, but could be wrong about that.)

FWIW, the ‘diskdev_cmds’ package provides some tools for checking HFS+ filesystems under Linux.
For others who come searching

where it is advised to check the file system before mounting r/w.
I meant to add that as with any valuable data partition, you should always have backups available, so this will mitigate the risk of not being able to restore files from a corrupted file system.
