Brand New Volume Missing 900GB, How/Why?

[Dizzy49]

I just installed FreeNAS the other day, and I created a RAID5 array with 5x 3TB drives.
When I created the volume in FreeNAS it displays:
Size: 11.6 TB
Available: 10.7 TB
Used: .9 TB (8%)

Why is there 900GB being used on a brand new volume? I added a 3TB drive to the array because I ran out of space, and now 1/3 of my additional space has disappeared.

Can someone explain to me what's going on there?

SSH on to the machine and run a few commands for us:

df -h

du /mnt/YOURPOOLNAME

And post the results

I am having the same problem. I have 2 x 2tb drive and my volume shows up as only 1.5tb what happened to the rest


df -h output:

tconley,
Remember that a 2TB drive will never format to 2TB. I think mine format to about 1.7TB.
Hard drive manufacturers round everything to the 1000 (not 1024), so 2000GB in their mind is 2TB, but in reality once you calculate everything with 1024 it comes out closed to 1.7TB.

My issue isn't that my 5x 3TB drives aren't showing up as 15TB (or 12TB in RAID5). It's that FreeNAS reports 8% is used from the formated space from the start.


Tekkie,
I've started to load up my drive so the output is quite large, and not something that I wish to share publicly. Is there a way to send the output to a file? Is there a certain part, or something in particular I can look for and paste?

 

[Tekkie]

@all,

FreeNAS8 will creaet a 2GB SWAP partition on all drives, its under Settings -> Advanced.

can you both run 'zpool status', 'zpool history', 'zfs list'.

@Dizzy49 can you still run df -h?

 

[Dizzy49]

Yes, df -h gives me:

Filesystem Size Used Avail Capacity Mounted on
/dev/ufs/FreeNASs1a 458M 399M 22M 95% /

Side question any particular reason for using UFS instead of ZFS?

What does 'gpart show' give?

PS. Put the output in

Code:

 block makes it easier to read as it keeps the format.

 

[Dizzy49]

Code:

Hard drive manufacturers round everything to the 1000 (not 1024)

Rounding actually has nothing to do with it. You might want to research the 1000 vs 1024 issue further.

Side question any particular reason for using UFS instead of ZFS?

I THOUGHT I read something that it wasn't as stable in FreeNAS8, and that it wouldn't give me good results in my setup (Hardware RAID5 that is seen as a single drive in FreeNAS). I was also a bit concerned about if my WDTV would connect to a ZFS share.

I've since read bits and pieces and I think I should have gone ZFS. Ah well, too late now. My wife will *KILL* me if I tell her we need to spend a week copying things back off of it.

Edit: Changed "would" to "wouldn't give me good results..."

 

[Tekkie]

:D I know what you mean by the 'wife' factor ;) I am currently doing exactly that because my ZFS vols are growing beyond the size specified...

Code:

=>         34  23441702845  ada0  GPT  (11T)
           34      4194304     1  freebsd-swap  (2.0G)
      4194338  23437508541     2  freebsd-ufs  (11T)

Code:

Filesystem   Size Used Avail Capacity Mounted on
 /dev/ufs/Media 11T 1.5T 8.2T 16% /mnt/Media

In the above the 16% usage of 11T adds up to 1.5TB which has me puzzled of the 8.2TB available... something is eating away at your capacity there.

 

[Dizzy49]

I'm about to set up another RAID5 with 5x 2TB drives, so I'll see how that looks after I set that one up. Then I should be able to move everything to that drive, then reformat the "Media" drive with ZFS. Then I need to figure out how to share it. My wife was PISSED at me today, when we couldn't get our WDTV to connect to my "Unix Share".
Mount point it /mnt/Media, and have All Directories checked, and the user stuff to set to N/A
I tried connecting to it a couple ways:

Code:

xmount "//192.168.0.134/mnt/Media" "Media3" cifs
xmount "//192.168.0.134/Media" "Media4" cifs
xmount "//192.168.0.134/mnt/Media" "Media5" cifs "user=Dizzy,pass=DzyPass"
xmount "//192.168.0.134/Media" "Media6" cifs "user=Dizzy,pass=DzyPass"

Unfortunately none of them worked. If I can't figure it out this weekend I think she's going to make me return everything!

Under CIFS, I have Anon for Authentication Method
Allow Guest Access is checked, and www is the guest account.

 

[Tekkie]

Would it help for your wife to talk to mine? :D They could start a group called 'FreeNAS anonymous'....

Regarding WDTV you did start the CIFS (aka. Samba)service? And you setup the Sharing tab as well?

 

[Dizzy49]

Yes, I have the CIFS service set to "ON"

I then have my share set up...

I'm not clear on how to access it with the WDTV, not sure how the url is supposed to look "/mnt/Media" or "Media", do I need a user name, etc...
I have no idea how to share a subfolder, but at this point I just need to get SOMETHING to work to appease the wife (and now my daughter who woke me up screaming at me b.c she couldn't watch her "pinceses" aka Barbie and Tinkerbell.

I was JUST able to connect with the WDTV to the Windows share though, so that keeps me out of trouble for the moment :D
