@Arwen, @essinghigh
After reading documentation, and few other forums, seems I am making some progress. Will you be able to guide in a direction with current situation that I am facing.
After trying few commands (and meddling bit with the SATA cables/ports etc) CLI shows pool as well as disks as online:
root@HomeNAS[~]# zpool import
pool: All4TBDisks
id: 14329411509399635582
state: ONLINE
action: The pool can be imported using its name or numeric identifier.
config:
All4TBDisks ONLINE
raidz1-0 ONLINE
gptid/7374a1f2-4796-11ed-980d-1027f526f244 ONLINE
gptid/737ee777-4796-11ed-980d-1027f526f244 ONLINE
gptid/7367fdfc-4796-11ed-980d-1027f526f244 ONLINE
gptid/738c0045-4796-11ed-980d-1027f526f244 ONLINE
However, when I try to import the pool using any of the options (-F or -f or -FX or -R etc), I get different issues with the disks. Sometimes it says “Faulted Too many errors”, sometimes it says “UNAVAIL cannot open”. Here are output of few of the commands:
root@HomeNAS[~]# zpool import -Fn -R /mnt All4TBDisks
root@HomeNAS[~]# zpool import
pool: All4TBDisks
id: 14329411509399635582
state: UNAVAIL
status: One or more devices are faulted.
action: The pool cannot be imported due to damaged devices or data.

I also found below command, and tried it with all the options like -F -f -FfX etc, but I keep getting same error (I/O error):
root@HomeNAS[~]# zpool import -f -o readonly=on All4TBDisks
cannot import 'All4TBDisks': I/O error
Destroy and re-create the pool from
a backup source.
zpool status shows only the boot pool.
root@HomeNAS[~]# zpool status -v
pool: boot-pool
state: ONLINE

root@HomeNAS[~]# zpool import -F -R /mnt All4TBDisks
cannot import 'All4TBDisks': no such pool or dataset
Destroy and re-create the pool from
a backup source.
root@HomeNAS[~]# zpool import -Ff -R /mnt All4TBDisks
cannot import 'All4TBDisks': no such pool available
root@HomeNAS[~]# zpool import -FfX -R /mnt All4TBDisks
cannot import 'All4TBDisks': no such pool available
I am a bit lost again as I thought if everything comes online then I’ll be all set, but seems the behavior is becoming more and more random (with the errors related to the disks). Any further guidance will be highly appreciated.
