that one uses a variant of dd. What isn't apparent is how <br>
one goes about cloning one's primary disk (active). From
searching it <br>
appears it is not recommended to use dd when the disk is
active, either <br>
the source or the destination.<br>
<br>
I'm trying to clone my nearly full SSD with the OS (Ubuntu
18.04) to a <br>
new larger SSD.<br>
<br>
Is there a tiny linux I can boot into that I can run dd from?
Or can I <br>
make the main disk ro? What do you suggest?<br>
<br>
I have backed up home. I really don't want to re-install the
OS, since <br>
I have had troubles with gdm3 screwing up (different topic).

<br>
Recommendations/recipes on the cloning process sought.<br>
<br>
I was simply going to use<br>
<br>
# dd if=/dev/sda of=/dev/sdc bs=4096 conv=sync,noerror<br>
<br>
I've seen lots of comments about block size and optimal
setting, but I'm <br>
not sure what is optimal if there are unknown (but few) source
drive errors.<br>
<br>
Thanks,<br>
