I have installed MD (swRAID) and MDADM (admin) on latest release TC.
I seem to be able to use MDADM to create a new array:
mdadm --create /dev/md0 --level=5 --raid-devices=4 --spare-devices=0 -f /dev/sda /dev/sdb /dev/sdc /dev/sdd
These are four 1TB SATA drives. I then cfdisk /dev/md0 and create a primary partition md0p1 (TC names it automatically) of 3GB.
I then mkfs.ext3 /dev/md0p1 and it seems to do what it is supposed to with no errors.
I then rebuildfstab.
There is no entry in fstab for /dev/md0p1. I manually entered one, did a backup and rebooted. When I checked fstab the entry I put in for /dev/md0p1 is gone, replaced by an entry for /dev/sda1 which is the first drive in the array.
Can someone suggest what I am missing please.
