June 17, 201214 yr Hello! I'm building another server for a friend who has been using the tried and true "as many external drives connected to my computer as possible" method. So I got two new 3TB drives and precleared them. They are now assigned as parity and data, and I am trying to mount the four other 3TB WD drives that he has all his data on to copy them to the array. But they are 3TB and thus GPT, and I can't find a partition to mount. There is only sdc, sde, sdf, etc, no sdc1, for example. How can I mount these drives and empty them into the server? I have taken his externals out of the enclosures and placed them in his case for speed purposes also. Thanks in advance! P

Or with data from when they were USB drives? What version of unRAID is on the other server? You must have a 5.X version. You must also have hardware that recognized the drives. Other than that, I've got no idea. Put them back into the USB enclosures. They might not work without the USB electronics.
June 17, 201214 yr Author They are WD MyBook 3TBs formatted as HFS extended journaled. I am running 5.0b14 on my server and rc4 on his. I am running almost the same hardware between them, x8sil-f mobo with the drives connected directly to it. I guess I can try connecting them usb, is there any issue with removing unmounted drives while the system is on? I don't want to interrupt the parity rebuild...thanks!
June 17, 201214 yr Author I tried mounting one still in its enclosure. I could see the partition, but it wouldn't mount. Here's start to finish from the syslog. I guess hfs+ bigger than 2TB isn't supported?

Is there something I can do or am I stuck copying from the enclosure to my laptop to the server? I mean, I'll do it, but if there's another way... Thanks! P
June 17, 201214 yr Is there something I can do or am I stuck copying from the enclosure to my laptop to the server? I mean, I'll do it, but if there's another way... You can re-write the HFS driver so it can handle file systems greater than 2TB. Then compile it into a cusom loadable module and finally install and use it. Other than that. According to the HFS wiki http://en.wikipedia.org/wiki/HFS_Plus In 2009, these drivers were diagnosed to be corrupting HFS+ drives with a capacity greater than 2 TB.[14] Consequently, Linux distributions such as Debian and Ubuntu also stopped allowing mounting of HFS+ drives or partitions greater than 2 TB.[15] As of February 2011, work is in progress to lift this restriction. If you do decide to re-write the HFS driver, this patch might be a place to start your investigation: http://www.spinics.net/lists/linux-fsdevel/msg42242.html Disclaimer... I've never used an HFS file system, and certainly never one on a 3TB drive, as I've never used one of those (a disk over 2TB) with any file-system... anywhere... ever. No idea if the referenced wiki is accurate, or if the patch works, or even where the source needed would be to be patched. I would suggest a bit of googling... In the interim, connect the drives as they originally were and perform the copy over the LAN. Joe L.
June 18, 201214 yr Author Wow, that definitely sounds like a job for someone much, much, MUCH smarter than I. I seriously don't know where I would start! Thank you very much for your help though, I completely missed that portion of the hfsplus wiki! Also, it appears that it won't mount exfat partitions/drives either, but I just started down that road. Thanks again, over the LAN we go!
