March 10, 201412 yr I am running the bata 6 unraid server I switched to it when I was having trouble with some of the pit falls of the g-force issues. I switched after seeing that unraid added support for my setup. Anyway my problem is that for some reason parity is reporting that their is 1 TB used on a drive I know to be empty. I did a parity check and it came out with no errors but it still says theirs 1 TB used. I also rebuilt the parity drive with the same result.I know it is empty because I can see whats on the drive in the main window of the web GUI. Is this normal or was unraid somehow fooled into thinking that their is something on the drive
March 10, 201412 yr What do you mean "parity is reporting that their is 1 TB used"? This doesn't really make any sense. Where exactly are you seeing this?
March 10, 201412 yr Author Okay this is what I am seeing..as you can see drive 4 is reporting 1 tb used
March 10, 201412 yr There's something on that drive. Only if i was absolutely sure it had nothing of value on it would i be removing it from the array by deassigning the drive and preclearing it in order to zeriose it before reintroducing. Strange one. Are you sure there's nothing on there, nothing showing under disk shares? Sorry jonathanm ... over to you.
March 10, 201412 yr If you navigate to \\tower\disk4 using windows explorer, what does that show? Or click the little folder icon on the far right of the Disk 4 line.
March 10, 201412 yr A single hidden folder at the root of disk 4 could easily account for this. From telnet or console, what does ls -al /mnt/disk4 show
March 10, 201412 yr Sorry jonathanm ... over to you. No problem, different methods to get to the same result. Another method, telnet, mc, navigate to /mnt/disk4 and see what's actually on the drive.
March 11, 201412 yr Author Okay here's what disk 4 has on it. Theirs no hidden folders or files the drive was precleared by unraid when it was added to the array
March 11, 201412 yr I don't think you can see hidden folders using that method. I just created a hidden folder and tried to browse to it from the webGUI and it didn't show up. Same probably applies to Windows Explorer. I'm pretty sure it won't show a hidden folder unless you have Windows Explorer configured to show hidden files and folders, and it might not even then. Haven't tried it though. This will definitely show any hidden folders on disk4 if they exist: From telnet or console ls -al /mnt/disk4
March 11, 201412 yr Also, from your Windows computer, Control Panel/Folder Options/View/Hidden files and folder/Radio Button "ON" for "show" That will turn it ON for all your computer drives, C:/ Drive as well as unRAID...
March 11, 201412 yr Can't parse this. Doesn't percent clean the drive of all files and folders? Just do what I said so we can help you get to the bottom of this.
March 12, 201412 yr Are you saying you Precleared it? Is it possible that you previously had multiple partitions on this drive, with a first partition of 1TB size? You might try fdisk on it. Actually, your syslog should partly show how it's partitioned.
March 12, 201412 yr Theirs no hidden folders or files the drive was precleared by unraid when it was added to the array The above makes it sound like it was cleared, not precleared. If it was actually precleared, then yes, all partitioning is removed, but I'm not so sure that Tom's clearing of an existing partition structure will clear beyond the first partition. It's a long time ago now, but I *think* I remember we used to be able to trick UnRAID into using a smaller partition, rather than the whole drive, by pre-partitioning it. I think you still could by setting up an HPA first. In addition to attaching a syslog, can you also show us the results of hdparm -I on the drive (eg. hdparm -I /dev/sdg)?
