This may not be the forum to ask
it is because you can type that sort of questions also into google and
there isn't a good reason to build your own kernel in 2022 for most usecases
this but what exactly is "compiling the
kernel". From what I've been reading, it sounds like a somewhat involved and
complex process - is it? Is compiling a new kernel the same as upgrading the
OS? I'm getting the impression that it sort of is but sort of isn't. Is it
possible to compile a kernel for a rescue CD (from the comments I've read,
it is possible)? If I were to compile a new kernel, would I expect the
version number for the kernel and mdadm to be the same? Sorry for all the
question but, as I said at the outset, a lot of this is all very new to me.
don't get me wrong but "Is compiling a new kernel the same as upgrading
the OS" and "what exactly is "compiling the kernel" implies just use a
binary distribution when it sounds that you even don't know what compile
software from source means

Sorry Reindl. I'm not sure I understand. Are you saying I did or
didn't do the right thing in booting from a CentOS rescue disk? At
the moment it's running from the rescue disk and, be it the best
distro to have used (or not), I would imagine that I need to keep
running from the rescue disk until the reshape is complete as
rebooting in the middle of a reshape is what got me in this mess.
and nowhere did i say reboot now
and i only responded to your "Do I understand that you would recommend
upgrading our installation of Linux once the repair is complete or are
advising downloading and compiling a new kernel as part of the repair?"
nobody said that - the only point was use a as recent kernel as possible
with all rgow/reshape operations
and i don't understand what you did not understand in the clear
response below you got days ago!
due reshape you where advised use whatever rescue/live system with a
recent kernel and mdadm, not more and not less
just to avoid probaly long fixed bugs in your old kernel
---------------------
Try and get a CentOS 8.5 disk. At the end of the day, the version of
linux doesn't matter. What you need is an up-to-date rescue disk.
Distro/whatever is unimportant - what IS important is that you are
using the latest mdadm, and a kernel that matches.
The problem you have sounds like a long-standing but now-fixed bug. An
original CentOS disk might be okay (with matched kernel and mdadm),
but almost certainly has what I consider to be a "dodgy" version of mdadm.
If you can afford the downtime, after you've reverted the reshape, I'd
try starting it again with the rescue disk. It'll probably run fine.
Let it complete and then your old CentOS 7 will be fine with it
