so run the cmds:
Code:mkdir -p /tmp/test
sudo mount /dev/dm-1 /tmp/test
sudo df -h /tmp/test
vtoy_persistent is a virtual device which mapped to the persistence file.
If the persistence take affect, the system should mount /dev/dm-1 to someware and use it as the persistence space.
The /dev/mapper/sda1 (Linux Remount feature) is not for persistence.
As always, I appreciate the continued support/guidance. I apologize that you have to "spoon-feed" this to me, but I still do not get it (and, I'd like to think, I know some of this stuff - I am former: 25yrs Bell Labs;8 yrs NASA; 6 yrs Raytheon;MCSE;CCNA;CLAD;RHCSA on RHEL 7). After my last email, I have started to learn about Copy-On-Write (COW). I also checked my Shell, and it's "bash" (so leaving out that argument from ExtendPersistentImg.sh should be OK).
I entered the three commands you suggested above, and I see that "/tmp/test" seems to "mirror" "/". See the "df" output below. My problem persists, though. I was able to successfully bring up Thunderbird email. When I went to "Compact Folders", I got a low disk space error. So, I must assume, that my persistence did NOT take affect (as you mentioned above). I, seriously, appreciate the help, but I am asking for more...any suggestions on how to make my persistence take affect???
