Thread: Request for advice on reading fdisk output

hi guys , gals,

total windows fanboy taking first steps ubuntu! i'm building nas server hardware raid 1.

i've got 250gb boot drive partitioned , setup installer - ok.
2x 2tb drives configured raid 1 in bios - ?

know have create partition , filesystem before mounting it, little confused fdisk output , should partitioning.

here output

code:

by process of elimination i'm guessing /dev/mapper/pdc_djgcaeihhd need partition , mount. correct?

also, plan on using ext4 fs, looking xfs (not installed). have large number of video (~600gb) , audio content made me think of it, millions of smaller files < 100kb. sharing through samba, worth installing xfs or using ext4 ok?

someone fdisk cli easy use. in meantime take @ gparted. if it's not installed can install "sudo apt-get install gparted" or type gparted in synaptic.

gui partition manager might easier use.
