[arm-allstar] all changes to system lost on reboot

[David McGough]

Hi,

The most likely issue causing this is corruption of the SD card 
filesystem---HamVoIP uses the Linux "ext4" filesystem for primary storage.  
Once you're sure you've got any important files backed up, it's possible 
to perform a filesystem check on an SD card, attempting to repair any 
damage.  This check can't be performed while the node is running. The 
simplest way to accomplish the check is to use a different Linux system 
and a USB SD card reader/writer.

Or, alternatively, boot your node RPi with a "stock" (unconfigured)
HamVoIP firmware image.  Then, plug the errant SD card into this system 
using a USB SD card reader/writer.

Once the SD card is plugged into the Linux system via the USB card 
adapter, it'll (hopefully!) show up as the storage device: /dev/sda
You can check this by listing the contents of the /dev/disk/by-id folder, 
for example:

....Here is this folder with NO USB SD card reader attached:

[root at RPi4B-dev ~]# ls -lisa /dev/disk/by-id
total 0
 1447 0 drwxr-xr-x 2 root root 100 Feb 22  2016 .
 1446 0 drwxr-xr-x 5 root root 100 Feb 22  2016 ..
 1448 0 lrwxrwxrwx 1 root root  13 Feb 22  2016 mmc-SB16G_0x85071a05 -> ../../mmcblk0
14538 0 lrwxrwxrwx 1 root root  15 Feb 22  2016 mmc-SB16G_0x85071a05-part1 -> ../../mmcblk0p1
14525 0 lrwxrwxrwx 1 root root  15 Feb 22  2016 mmc-SB16G_0x85071a05-part2 -> ../../mmcblk0p2

....And, here it is again, after plugging the USB reader w/SD card in:

[root at RPi4B-dev ~]# ls -lisa /dev/disk/by-id
total 0
   656 0 drwxr-xr-x 2 root root 160 Mar  4 01:53 .
   655 0 drwxr-xr-x 5 root root 100 Feb 22  2016 ..
   657 0 lrwxrwxrwx 1 root root  13 Feb 22  2016 mmc-SB16G_0xeb13d897 -> ../../mmcblk0
  1778 0 lrwxrwxrwx 1 root root  15 Feb 22  2016 mmc-SB16G_0xeb13d897-part1 -> ../../mmcblk0p1
   767 0 lrwxrwxrwx 1 root root  15 Feb 22  2016 mmc-SB16G_0xeb13d897-part2 -> ../../mmcblk0p2
297848 0 lrwxrwxrwx 1 root root   9 Mar  4 01:53 usb-Mass_Storage_Device_121220160204-0:0 -> ../../sda
297861 0 lrwxrwxrwx 1 root root  10 Mar  4 01:53 usb-Mass_Storage_Device_121220160204-0:0-part1 -> ../../sda1
296494 0 lrwxrwxrwx 1 root root  10 Mar  4 01:53 usb-Mass_Storage_Device_121220160204-0:0-part2 -> ../../sda2


....And, the sda device (with 2 partitions: sda1 and sda2) is now visible.  
To perform the filesystem check, run this command.  Note that any errors 
should be automatically corrected:

[root at RPi4B-dev ~]# fsck.ext4 -fy /dev/sda2
e2fsck 1.42.13 (17-May-2015)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/sda2: 92694/243360 files (0.1% non-contiguous), 582884/972182 blocks


....Finally, unplug the USB SD card reader/writer and try out the 
"repaired" SD card.
