"telinit" was what I needed, thanks again!

I'll try that...I was using instructions I found on the internet for
single-user/maintenance mode. From the grub screen you enter 'e' and
modify the linux16 line...etc.
Okay, I'll try that next.
Thanks Simon!

Hi,
Yeah, I tried that but ran into a problem. It came up fine in
single-user/maintenance mode. The mount command shows all of the
mounted file systems, but after I 'chroot /sysroot', the mount failed
(with some problem with mtab, sorry don't have the exact error
message). So I couldn't mount my 32TB RAID (where the xfsdump file
was).
I think you misunderstood what I meant. You appear to have booted into
rescue mode, but that's not what I meant. What I meant is good old
single
user mode. The state you'll get with "telinit 1" or with "s" or "1" as a
kernel boot option.
For what you want to do not a single reboot is required.

Hi,
I'm having some difficulty finding a method to shrink my /home to
expand
my /. They both correspond to LVMs. It is my understanding that one
cannot shrink a xfs filesystem. One must back it up (xfsdump),
remove
(lvremove) redefine it and then restore it back (xfsrestore).
Okay, I'm running into a problem where /home needs to be
"unused". If
tried going in to "maintance mode", but I ran into a problem with the
mount command (after issuing a 'chroot /sysroot'). I then tried
using
SystemRescueCD to boot to, but it wouldn't mount my 32TB RAID USB
drive
(something about too big).
Any thoughts or suggestions?
What is the problem if you boot directly into maintenance mode?
Then it
should be possible to backup home to a remote destination, unmount
/home,
remove the home LV, expand /, recreate home and mount it, restore from
backup and you're done. No need to use any SystemRescueCD or other
tool.

Simon
