Novice here that gets confused easy, spent hours reading on how to handle my situation so here goes. Server is used as media server, home movies/pics are backed up offsite. several weeks ago upgraded to 6.2.4 installed a 2nd parity drive - all had been working fine. This left me with P1 3TB P2 4TB D1 through D9 collection of 1TB to 3TB drives. Read some forums decided it was time to switch to xfs from reiser As I moved data around disks and changed file systems D9 came up with current pending sector 441, offline uncorrectable 192 and Reallocated sector count 0. I have moved all data from D9 to other drives, reformated by changing its file system to btrfs to force a format, everything appears to be functioning. I have a 4TB drive to arrive in a couple days I plan to install as P1, and will use the old 3TB parity as my D9. 1)Can I, just preclear the 4TB, install as P1, let it rebuild, then take the old P1 3TB drive and swap out with D9. I read cautions about rebuilding arrays if any data disks has pending sectors. 2) Should I do this: (The "Clear Drive Then Remove Drive" Method) referenced here (https://lime-technology.com/wiki/index.php/Shrink_array) to shrink the array first, removing D9, then just adding back in later with a good disk. Is thier something else I should do, i read about preclearing a drive with pending sectors to get them to reallocate, but not sure if i should do that with a drive that is part of the array. Thanks,

I ran into what Pat did, "If you have never run the New Permissions tool, or are upgrading from a version prior to v5.0-rc9, then you MUST run the New Permissions tool, even if you have run it before. It's on the v6 Tools page." Is this a typo? Should it be the V5 utilities page? I copied my V5 Backup back to flash, will run permissions util, if no luck with that I will try the make bootable. up and running now. To get upgrade to work I followed the plugin steps, moved flash drive to PC, DL the V6 zip and copied the syslinux file to the flash drive, then ran the makebootable bat file. (running makebootable does not work after plugin upgrade since syslinux folder did not exist) Then moved flash drive back to unraid server, and powered back up.
