[arm-allstar] Arch Linux Partition Size, Need to Increaas in ReInstall

[Jeffrey Messikian]

I have been looking into parted as well as gparted and have had no such
luck.  The big problem I see is that the root partition is mounted.  
I am not a linux expert, so there is that too.  I am able to resize the
partition, but extending the file system is the real problem.  For that I
have been looking into resize2fs.  

fdisk -l
Disk /dev/mmcblk0: 14.9 GiB, 15931539456 bytes, 31116288 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x5e8c3e13

Device         Boot  Start      End  Sectors  Size Id Type
/dev/mmcblk0p1        2048   206847   204800  100M  c W95 FAT32 (LBA)

resize2fs /dev/mmcblk0

resize2fs: Device or resource busy while trying to open /dev/mmcblk0
Couldn't find valid filesystem superblock.

No Joy.

Hmm. Seems I've done live root partition resizing on a HamVoIP system 
before while it is running using parted. I'll have to go back and look 
at what I did. I've definitely done it on stock Raspbian without using a 
second device. The partition boundaries take effect on reboot. The 
safest option here would be to resize the partition on another system. I 
was doing this on a data center hosted Pi 1000 miles away running 
HamVoIP, so I didn't have that option. Could have added a second 
partition in the unallocated space, which also would have been safer, 
but I chose to resize the root partition and did so successfully without 
anything bad happening.
