HW RAID is often delivered with quite limited fun

Hi all;
I'm trying to setup an ssh tunnel so I can run firefox on a remote
laptop and have the display locally.
I have 2 laptops
local = CentOS 7
remote = mac OSX 10.15.7
I want to create an ssh tunnel on the local CentOS 7 laptop, then run
firefox on the mac with the display showing up
I do it all the time.
make sure you forward X11, on the ssh server side, and login with
ssh -X me@myhost.whatever
start firefox with:
/usr/bin/firefox -no-remote if you don't want the remote pages ending
up in your local browser
or if you don't care, just run firefox without -no-re
I can ssh -X myuser@theremote-mac
but I cannot run /usr/bin/firefox.
I can run "open -a Firefox" on the mac but then it just opens firefox on
the mac
Thoughts?

if it doesn't want to run, it probably is because you're not forwarding
X11 in your server, in this case your mac. the ssh server nees to
do/allow that
what about executing it remotely :
ssh -X myuser@theremote-mac "open -a Firefox" ?
if that doesn'

yeah .. it would need to run X11

When was the last time you tried it?
Why would you expect that a modern 8-core Intel CPU would impede I/O in any
measureable way as compared to the outdated single-core 32-bit RISC CPU

With ZFS, you set a partition label on the whole-drive partition pool member,
then mount the pool with something like “zpool mount -d
/dev/disk/
in large raids, I label my disks with the last 4 or 6 digits of the drive
serial number (or for SAS disks, the WWN).this is visible via smartctl,
and I record it with the zpool documentation I keep on each server
(typically a text file on a cloud drive). zpools don't actually care
WHAT slot

Oops, I’m mixing the zpool and zfs commands. It’d be “zpool import”.
And you do this just once: afterward, the automatic on-boot import brings the
drives back in using the names they had before, so when
