Re: [Samba] Writing on an HFS+ drive on raspberry pi

Hi Waishon,

Yes I did correctly mount the hfs plus drive using fstab.

I can write files in the drive when I am logged in as a user .

It seems that via the samba connection I cannot write files from my Mac, correct. 

I do not the possibility the use the share, but I don’t know what you mean by disabling the unix estension. I will read up on it.

Unfortunately mac doesn’t come with getfacl but I have read that the option -e of ls should replace it, here’s the output:
sudo ls -lae
total 112
drwxr-xr-x@  9 root    wheel    288 Mar 25 23:37 .

drwx------   1 andrea  staff  16384 Mar 25 23:40 andrea

the mounted drive andrea is the home directory on my pi on which I do have write permissions. I am not sure why Time Machine (the backup drive) has been mounted twice with different permissions.

Also since the latest release of samba (4.8.0) came out with support for time machine I decided to compile it myself and give it a go. The drive is formatted in HFS plus. The main problem that I am having is that even though I can mount the drive on the raspberry pi with writing permissions, I still cannot manage to write to the drive. At first I thought it was a problem of the interface between samba and time machine, but after trying out CCC as an alternative, I noticed that even CCC couldn't make backups because it couldn't create the sparsebundle image. Also, if I access the samba drive from finder I cannot create folders nor delete/rename them. So, I realised that the problem must lie within permissions. So far the steps that I have taken to get towards the right direction are: 1) I have installed hfsplus, hfsutils, hfsprogs
> to give HFS plus support to the Rpi. 2) Disabled journaling on the drive. I have read in a few forums that journaling prevents Linux systems from writing on hfsplus drives. 3) Edited the /etc/fstab to force mount the drive as -rw. From the command mount the drive appears to be mounted as rw. 4) The drive has been added to the smb.conf file, with the option read only = no. This should make the driver writable according to the documentation. 5) Since these steps were not enough, I decided to create a new user on my Rpi with the same name and id as my mac user. I added the user as a samba user and made the user own (recursively) the directory in which the drive is mounted. Also, everything in the directory has rw permissions for both user and group. 6) I also made sure that the uid for the drive directory matched with the uid of my mac user (501). After trying all of these options, I still cannot write on my backup drive and this prevents me from backing up my data (but I can write in
> the default home directory created by samba, so I think that the problem should not have to do with samba's configuration). I really do not know in which direction to go now as I feel like I have exhausted every option. Is there a kind soul around here who has a clue on what else I could try?
