May 20, 20251 yr A co-worker encouraged me to try unRaid and I am really savoring it thus far. Should have it mastered in a day or two. :-)So I asked him about his screen clip below and he really didn't have an explanation. He is a long time user.Why is my 8TB drive only showing up as 5.5 TB and showing on 2.98 TB free with only 24.GB used?Second, why is my second drive not listing a File Structure like the first drive, btrfs.--I also noticed I can set a spin down idle time on the first drive, but not the second drive. Not sure why this is.Lastly, should I when the trial ends, purchase a subscription, and restart this whole process with xfs instead? Edited May 21, 20251 yr by RaidPC Added to question on the drives.

May 21, 20251 yr Community Expert Is there a reason you created a pool using two differently sized HDDs? The typical unraid setup would have been to assign the two drives to the "Array" slots NOT a pool.While there is nothing wrong with using HDDs in pools, it's generally not ideal to mix disk sizes in pools. If you're going to use HDDs in a pool you'll want at least a minimum of 3 of the same sized disks and to use zfs raidz so you can get a speed benefit and a form of parity for the data on that pool.If I were you, I would put the 8TB disk in Array Slot 1 and the 3TB disk in Array Slot 2, and get a small SSD or two and assign them to a new pool. Otherwise you're going to end up with a less than optimal disk configuration which will likely lead to issues down the road. Edited May 21, 20251 yr by MowMdown
May 23, 20251 yr Author No reason, just a noobie who set it up the first time. I am researching more each day how to do it right.
