Linux / Fedora 22 mount Mircosoft Storage Space

The_1ted · October 25, 2015

Hi,

I just set up dual-boot system with Windows 10 and Fedora 22. Everything worked just fine, until I wanted to mount my Storage RAID 0 (jep I know, don't tell me).

When calling "mount /dev/mapper/pdc_cbfjedbjb2 /mnt" I get the following error message

mount: /dev/mapper/pdc_cbfjedbjb2 is write-protected, mounting read-onlymount: wrong fs type, bad option, bad superblock on /dev/mapper/pdc_cbfjedbjb2,       missing codepage or helper program, or other error       In some cases useful info is found in syslog - try       dmesg | tail or so.

dmesg | tail shows in my mind no useful information

fdisk -l gives the following information

The RAID-Array is on /dev/sda and /sdb.

/dev/sdc is the main SSD with Windows and Fedora installed

/dev/sde is a SD-Card

and just for some more readable info. here is lsblk

What is think the problem might be is that the array is shown as a Mircosoft Storage Space which might not be compatible with Linux.

One solution might be to find another way to configure the array so that it can be mounted in both OSs, but I don't want to give up just yet.

dmesg | tail will only display the last 10 lines by default, try with

| less

instead, that should print out the whole thing divided into pages and you can scan for errors / problems.

Additionaly, what FS does the MSS have? While in windows open the command prompt and

chkdsk <your partition> /f

( i.e. chkdks c: /f ). That should print out the FS type for that particular partition. Though my knowledge is severely limited with this particular thing I seem to remember that MSS is a software storage pool type that uses a filesystem that's a bit odd ( ReFS ) and mounting it might require some hoop jumping.
