For anyone searching and running up on this thread. That command did work to disable the drive. I'm not sure if I should have used pvchange to disable /dev/sdk1 or not. The problem I did run into was getting it back. I ran the command to enable it but it didn't work as expected. I had files missing. So, I unmounted it, ran pvscan, vgscan and lvscan in that order. I then ran the command above again to be sure and remounted the LV group. It worked that time. All files were there. So, either one has to rescan them or I should have also ran pvchange to disable as well. Maybe someone else can expand on this. While I'm at it. Is there a way to reset the sdk part? The old was sdd and I was hoping when I moved the drive, it would change with it. The reason is, usually when I hook up my external drives, they use sdk. I'm sort of set up for that. A couple other things use sdk as well. I'm not sure if there is a easy way to do that or not. Wonder if it will reset when I reboot??? Dale :-) :-)
