Removing four disks

[tucansam]

I have begun replacing 8TB disks with 12TB disks, and now have a little wiggle room.

 

Several very old 3TB and 4TB disks, four to be exact, need to go -- they are throwing errors and I have just finished copying all data off of them and onto other disks.  The four disk are blank.

 

I've read the FAQs and how-to's about doing a New Config.  But before I take the plunge and remove four disks at the same time, I figured I'd post here for one final sanity check.

 

What is the preferred procedure for permanently removing these four disks from my array?

 

Thank you.

Do a new config without them and sync parity.

Thanks.  Unfortunately I can't get a parity check to complete (the reboot issue I am trying to figure out) so I'm worried about doing it because I don't think a parity sync will work right now.

You probably want to fix those stability issues before doing anything more around the disks then. All the ways of removing disks and maintaining/restoring parity protection involve long operations.

The PS I am using is a Seasonic gold, ten months old.  I don't believe it to be a power issue.  The random reboots I am experiencing during a parity check came as soon as I added two 12TB parity disks and a 12TB member disk.  I'm not sure where to start troubleshooting this particular issue.  Removing the extra disks I mentioned above will allow me to remove an extra HBA that is running an external enclosure... I am slowly trying to eliminate variables.  I was hoping to be able to get that all out of the system before I move on, as that stupid setup has caused me nothing but major issues since Day 1.
