copy from gpt (guid partition table) formatted drives

[PeteAron]

Hi All,

 

I am a newb and I have my array up and running.  I have about a TB of files on a 2 TB disk that I would like to copy using the drive as an internal drive to take advantage of the faster transfer rates.  I have a problem.

 

I started the array, and tried to mount the disk using the wiki instructions, but get an error:

 

mount: wrong fs type, bad option, bad superblock on /dev/sde,

      missing codepage or helper program, or other error

      In some cases useful info is found in syslog - try

      dmesg | tail  or so

 

then:

root@Repository:~# fdisk -l|grep ntfs

 

WARNING: GPT (GUID Partition Table) detected on '/dev/sde'! The util fdisk doesn

't support GPT. Use GNU Parted.

 

 

is there a way to transfer files from the GUID partition table disk or am I sol?

 

Thanks!

what version of unRAID?

 

Basically, the answer is yes.  There is a way to access the partition, and it is exactly the identical way you would if it was an MBR partition, and you would NEVER use fdisk in mounting the disk to access it.

 

if the partition is recognized, it will show in

/dev/disk/by-id

 

and when you type

cat /proc/partitions

I am using unraid ver 4.7.  I just bought a copy of Plus last weekend.

 

thank you, I will try this and report back.

I'm not sure a GPT partition is supported in 4.7. It should be in the newer 5.0b series.

basically correct, although I'm not sure if it is entirely ignored in 4.7, or if unRAID does not use them.

The kernel in 4.7 seems to have support configured for GPT partitions.

CONFIG_EFI_PARTITION=y

I am currently experiencing this same issue. Were you ever able to get this to work?
