Hi all

 

I recently added a new parity drive [4TB] and moved the old parity drive [2TB] to the array as a storage drive.  Its all gone in fine but the array is not using the new drive.

 

Since adding the new drive, one of the other drives has now hot 100%, and as of today the cache drive is sitting at 20% (other two drives are at 96% & 97% - both 2TB)

 

When I added the drive I went into each of the shares and added the drive as a drive that they could use, but it was never used so I have since gone back in and removed any references to allowed disks.  Each share is showing the extra space as  i.e. 2+TB so it appears that they know its there.

 

Settings > Share Setting is clear so there is no specifically included or excluded disks there.

 

What have I done wrong or why has this happened and how do I fix it.

 

Is there a way to drop the drive that is at 100% down to 97% odd percent - not reason why I suppose, just dont like the idea of 100% used.

 

Unraid 5 beta 12a

 

Thanks

You could simply move some data off of it.    But why don't you want to use all of the space on the drive?    There's nothing wrong with filling it up !!

 

 

... as for why the array's not using the new drive => did you set the "Includes" using the standard interface, or using Simple Features?    If the latter, I'd disable Simple Features and use the standard interface.    There are some issues with SF and v5 that have not been fully resolved yet.

 

Also, upgrade your system to v5.0 => there's not much use trying to resolve an issue with an earlier RC when it may/may not even be an issue with the actual release.

 

Yes, I have SF installed.  Not sure I remember how to disable that now.

 

As for upgrade, need to learn how to do that as well and how much trouble it is.

 

Thanks

Just looked again -- you're not even running an RC ... it's an earlier Beta.

 

I'd just start with a completely new v5.0 install on the flash drive.

 

First, be sure you back up your current flash drive -- especially your key file.

Also, be sure you know which drive is assigned as parity and (if you have one) as the cache drive.  Be SURE you know those -- and that you assign them correctly when you build the new v5.0 config.  The order of the data drives doesn't matter when you assign them.

 

Then download v5.0;  extract all the files to a folder;  format your flash drive (be sure it's labeled "UNRAID");  copy all the files from the v5.0 download to it;  run the Make_bootable.bat file from the flash drive (run it with administrative privileges);  and then you're ready to go.

 

Book your UnRAID system with that flash drive; and assign all of the drives EXCEPT your parity drive.  Start the array and confirm all looks good (no drives show as Unformatted);  then Stop the array; assign the parity drive; and finally Start it again and wait for it to do the parity sync (many hours).    When that's done, run a parity check to confirm all went well -- and then you're ready to add anything you want to use (but do NOT add Simple Features).

 

Thankyou for that.

 

What are the chances that the drives will loose all their data.  A backup of 6TB is going to be long and painful.

 

It also sounds like it would be easier to start with a new USB key - would that be correct or am I missing something obvious.  Forgive the simple questions, but I do not live in the unraid world - I set it up and it has been running for me without much interventions required so I have lost all the knowledge I gained from the original setup.

 

Thanks

You should, of course, already have backups of your data.  UnRAID (or any other RAID) is NOT a backup.

 

But notwithstanding that, you won't lose any data if you do what I suggested.  The file system on the disks doesn't change at all with the newer version.

 

Yes, I know that is the obvious reply and I do backup a lot of important data (photos etc) but there is a lot that is not backed up that I prefer not to lose but is not critical enough to warrant a second unraid system or other forms of large data storage.

 

I will give it a go and cross my fingers.

 

How do I disable SF

How do I disable SF

 

Just start over with v5.0 and don't install SF this time.

 

Stupid question, where is the go script?

 

That is how much I have to re-learn

In the config folder on the flash drive

I remember reading that You never want the drive to completely fill up, you always want to leave up to 10% of the drive free for the RiserFS journal.  Filling the drive up, then loosing power and you could be in a really big mess.

 

You always need to save some space for the RiserFS journal.  Same thing in Unraid, if you have 10% or less of any drive left, it is recommended that you stop adding files until another drive is added.

 

This posting on the unraid Forms also suggests 10% or more should remain free on each drive to keep performance at maximum.

WRITES do indeed get very slow when the disk get close to full -- but READS aren't impacted at all.

 

If a disk is ALREADY full, there's no reason to move things off of it to make it "less full".

 

My array works just fine with full disks -- I've tested this by streaming 5 movies at once off the same "full" disk.  Yes, it was slow when I wrote the last few DVDs to the disks to fill them up ... they're now simply "static" disks that never get written to ... but are frequently read.

 

Reads are also no issue -- data from the full disks is just as fast as that from those with plenty of spare space.

 

Here's my current drive usage:

 

how do you "move files off a drive".  Is it just a case of going to the share that is created for the specific drive and moving it to another specific drive share or do you have to copy it off the server, delete it and then copy it back to the server?

Move to a specific drive share.

you can use Midnight commander.  mc is the command.  then you can move files from one drive to the other.

my method of choice is the command window... for example something like the following command has proven to be very useful to me...

 

mv /mnt/disk1/Movies/* /mnt/disk2/Movies

 

this would move movies from disk1 to disk2... there is good wiki info on the methods one can use to do this sort of thing (midnight commander, command window etc)....

Thanks guys.

 

What it did force me to do was look at what I had there and I deleted a lot of crap which created about 5% of free space on that drive.

 

I wil still look at what has been offered up as it is something I should know.
