Lost space on drive

Featured Replies

I'm doing a little housekeeping on my unRaid, moving files around and reorganizing the drives.

 

Normally when I move all the files off of a drive, the unRaid webpage will show the number of free bytes as being equal to the disk size. For one of the empty drives though, there is a disparity and the amount of free bytes is less than the disk size by about 70 MB.  I did a file system check through unmenu and it didn't show any problems, but I'm worried something is messed up on the disk.

 

The array is not currently parity protected while I am moving everything around and I'd like to fix this problem before repopulating the drive.  I tried mkreiserfs and it reformatted, but it did not solve this problem. Anyone have any ideas on how to fix this problem short of spending 12+ hours pre-clearing it?

I now have two drives that are empty and both don't show full free space. I precleared one of  them and it didn't change anything. I guess I was wrong about empty drives showing full free space, I must have mis-remembered.

By chance, has an HPA been added?

hdparm -N /dev/sdX

will tell you.

 

What do you consider "full space"  Any file-system has its own administrative overhead.

I thought that whenever I stuck in a new drive, that what the webpage showed for "free" was equal to what is showed for "size".  I don't have a new drive to test that, but after preclearing one of the old, emptied drives (which I assume would reset it to how it looked "new"), those two values are not the same, so I guess I was wrong about that. There is like a 50 or 60 MB difference.

 

I ran that hdparm command and got the following response:

 

/dev/sdf:

max sectors  = 976773168/3694640, HPA setting seems invalid

 

I did a random sampling of drives and they all say the HPA seems invalid - is this something I should be concerned about?

Nah... many drives say the same thing.  The code reading the drive HPA has not caught up with the the latest manufacturers.
