Write access for HFS+ using hfsprogs

Postby iTycoon » Wed Dec 04, 2013 10:26 pm

How do I get write access to HFS+ drives? They mount as Read Only. I know I need hfsprogs but there's no package in Arch Linux Arm and I don't know how to compile it. Can someone point me in the correct direction?

I originally had Time Machine backing up to an sparsebundle image on a ext3 drive accessed via samba. It was backing up and restoring individual files and folders with no issues.

The problem arose when I needed to restore the entire system from a time machine backup and was unable to get the sparsebundle image to be visible when booted to the restore partition on the macbook. I want to have Time Machine work over the network to the Pogoplug such that I can connect the drive via usb to restore the entire system if needed, not just individual files and folders.

I figured what I needed to do was have a dedicated drive, formatted HFS+ as required by Time Machine that will mount on boot to be visible to the Time Machine restore process on the restore partition, not realizing that HFS+ is not natively supported on Linux and no package available for ALARM.

If I'm barking up the wrong tree, please advise.

Much appreciated!

Thanks for the response WarheadsSE.

I looked into disabling journaling. There are 2 issues with that. It seems that should be a fine solution provided I'm good with a fsck if something should go awry and the drive is improperly ejected however, Mavericks does not have an option for Mac OS Extended not journaled. I can't reformat the disks to disable journaling. Is there another way to disable journaling? I don't thinks so but maybe someone else knows better.

I've read up on AUR, ABS, etc. and I understand how to make a hfsprogs package now.

My question now is does hfsprogs enable support for journaled HFS+? If so, I'd rather go that route then disabling journaling on the partitions.

Thanks!

Edit: I figured out how to disable journaling. Also, when I run makepkg, I get:
Code: Select all
[root@Pogoplug hfsprogs]# makepkg --asroot -s
==> ERROR: hfsprogs is not available for the 'arm' architecture.
    Note that many packages may need a line added to their PKGBUILD
    such as arch=('arm').

Should I add 'arm' to the PKGBUILD?

If you want to use it on your arm processor, then, yes :)

Or just use makepkg -A ...

I have successfully installed hfsprogs and hfsutils using the AUR wiki (http://wiki.archlinux.org/index.php/Arc ... Repository) and I have successfully mounted with rw access with journaling enabled:

Code: Select all
/dev/sdc2 on /run/media/root/hdtv type hfsplus (rw,relatime,umask=22,uid=0,gid=0,nls=utf8)
/dev/sdc3 on /run/media/root/macbook type hfsplus (rw,relatime,umask=22,uid=0,gid=0,nls=utf8)


I should now be able to backup 2 macs over the network and have file level restore over the network. Should I need to restore a system from Time Machine backup, I should be able to do so with the usb drive directly connected.

Thanks for you help. Now if I can just get Netatalk to work ;)

If I'm reading this correctly, as of July 2013, this is a Netatalk bug that no one is working on. Did I read that email chain correctly?

Re: Write access for HFS+ using hfsprogs

After installing hfsprogs and hfsutils from AUR, what else did you do to get write support for journaled HFS+ drives?

I've added an entry to my fstab:
Code: Select all
/dev/sdc2       /media/mac hfsplus rw,relatime,umask=0022,uid=0,gid=0,nls=utf8 0 0


but when I run
Code: Select all
mount /dev/scd2


all I get is:
Code: Select all
/dev/sdc2 on /media/mac type hfsplus (ro,relatime,umask=22,uid=0,gid=0,nls=utf8)


Any thoughts?

@hdan42, Sorry so long on the reply. It' s been a while since I've done anything with my plug.

Actually, I don't remember what I did. I apologize. It ran flaky at best, mounting sometimes, others not. I ended up getting a wired USB drive for TM after reading that SMB support might be coming back (TM used to support it). I'll wait and see.
