Thanks for your details on things I should consider.
Yes, I think I got them to reference the new tools. I actually changed the pointers to the tools, as for some reason I can only get them to install under /usr/local/bin (I worked through the other thread on Kernel updates, and finally realized that while I had the new tools, they were never installing in the right location, despite using things like --prefix during the configuration option.
Unfortunately, it seems I am suffering from the same issue as posted in this thread. the latest version is not offered to me. It is an RPM install (i.e. loooong time ago used the iso to install). I checked in appman and my subscription is still active and valid, so I am not sure, what’s going on there. I will PM your my appliance ID, and hopefully you can figure it out:
I am currently not using quotas, so I don’t think I have to specifically turn them off.
Thanks for referencing the btrfs-progs thread, I remember reading about that a while ago, but forgot again that this might be an issue.
I think you are correct that I still have a SATA port open (just no a caddy to permanently hold a drive). So, you’re suggesting to basically add one of the larger drives as a fifth one to extend the pool and then start with replacing the others?
