Finding Free Space

I used Disk Utility and erased all my free space. It entered "zeros" into the free space so cannot save anything anymore. How do I get rid of these "zeros"?

When you elect to erase free space, Disk Utility creates a file that takes up all the free space, then writes zero's to it. If the process is interrupted or doesn't complete normally, that file is left on the system and all of a sudden there's no more space available on the disk.
To get rid of the file, if you have a program like Disk Inventory X or an older version of Whatsize, you can see all the files and easily identify and delete the file (as I recall it's a hidden file). If you can free some space up, you can download the old version of Whatsize from http://www.free-mac-software.com/whatsize/

Lion takes long time to find free space after emptying trash

After emptying the trash, I've noticed that Lion does not see the additional free space until after doing a reboot, and even after that it takes a long time for it to find all the new free space. Anybody know what's wrong with the trash system?

Absolutely nothing is wrong with it. See Missing disk space in Lion.

Solaris volume manager ; finding free space

Hello
Is there a way to find out the space available in a metadevice for creating new soft partions?
I am looking for the equivalent of the following vxvm commands
vxdg free
vxassist maxsize
Thanks in advance

If it is indeed showing as free space have you tried just extending your existing volume instead of making a new one?
You can right click your existing volume in disk manager and say extend partition and just next through the wizard. It should auto set all the values to consume is all the space.
Option 2 is to use the command line utility called diskpart. Go to start, type cmd. After the command prompt is open you will type diskpart.
First list the disks by typing "list disk" then select the disk you wish to work with. Example "select disk 1".
Then list the volumes, similar to disk you do "list volume". You then select the desired volume you want to extend. Select the 58.8 GB volume similar to selecting the disk. After the volume is selected you will type "extend" and
it will grow the volume into the free space.

How to find free space in a Tablespace?

Hi,
I have a limited access to objects in my database ( do not have access to many tables).
I have been allocated 300GB of size in my tablespace which allows me to create my objects.
Now, I want to find out how much of this tablespace size allocated to me have been used up. I do not have access to dba_data_files or dba_segments.
Is there a way out for me? Could anyone show me a way please?

This query will give you the required information but it makes use of DBA tables.
SELECT B.TABLESPACE_NAME, TBS_SIZE SIZEGB, A.FREE_SPACE FREEGB
from (select tablespace_name, round(sum(bytes)/1024/1024/1024 ,2) as free_space
       from dba_free_space
       GROUP BY TABLESPACE_NAME) A,
      (select tablespace_name, sum(bytes)/1024/1024/1024 as tbs_size
       from dba_data_files
       group by tablespace_name) b
where a.tablespace_name(+)=b.tablespace_name;
However, you said that you are aware of your tablespace details so the above query can be modified to get the free space in your tablespace. Now I am using user_frees_space and not dba_free_space. Generally user* tables are and should be made accessible to the users.
select tablespace_name, round(sum(bytes)/1024/1024/1024 ,2) as free_space
from    user_free_space
where   tablespace_name = 'Your tablespace name'
GROUP BY TABLESPACE_NAME;

How to find free space in an ArrayList...

Hi,
I have an ArrayList with data randomly assigned to different indexs of the ArrayList.
I want to find out where the "gaps" are within the ArrayList... For Example There would be data in index 0,1,2,3,5 but not in index 4 . How would I go about finding this information.
Thanks

I am i right?No, it will not fill a gap.in fact it will, after a fashion.
When you remove an item the remaining items are reshuffled to close the gaps.
When you try to insert an item beyond the last position (so at list.size()+2 or greater) you will get an error, and the insert will fail.I was more thinking of a situation like this:
        strings.add("One");
        strings.add("Two");
        strings.add("Three");
        strings.set(1, null);
        System.out.println(strings);The element at index 1 will be null (a gap in my view), since remove won't cause a gap.

Hi,
If you're looking freespace in diskgroup i believe you can use the first one
second script is looking freespace per each disk

Oracle Free Space Management

Is Free Space Management a Initialization Parameters,
if so which one,
Where is Free Space Management keepth ?
Eric

Eric, Free space management is not a database parameter. You should read the Concepts manual. It explains Tablespace management and object management basics. Or you can see the chapters devoted to Tablespace and Object management in the DBA Administration Guide for a more detailed analysis.
To find free space in the database see the dictionary view: dba_free_space.
To how space management is handled for a tablespace see the dictionary view: dba_tablespaces.

Finder showing incorrect amount of free space

After the recent Mountain Lion update, my Finder now shows an incorrect amount of free space.
I have a 500GB hard drive, and I have about 150GB free.
After the update, finder says I have 478.4 GB free?
That looks like the total capacity, after you account for system software. I've done a PRAM and SCM reset, disk verification and repair, but still no joy.
Any thoughts? Is it a bug in the update?

Here is the answer....

Re: Hard drive available space shown incorrectly in finder Jan 12, 2012 7:35 PM (in response to ilari Korte)
This is probably like the issue that I was having on my MacBook Pro. If you are using Time Machine on a laptop it stores the diffs in a file on your hard drive. This action can be disabled with the terminal command
sudo tmutil disablelocal
This turns the local Time Machine off. It is up to you if you want to do this, but Finder shows this space as unused since it can be overwritten when needed. It saved me over a hundred GBs of space.

Finder showing wrong amount of free space on Macintosh HD

Hi!
Does anyone know why Finder tells me that the amount of free space on my Mac is 46.53 GB while Disk Utility says there are only 31.89 GB of free space left?

Just found the solution in another thread: the "problem" seems to be the local Time Machine Snapshots. Finder ignores them, Disk Utility doesn't.

Finder reports wrong amount of free space

Finder is reporting the wrong amount of free space on all my drives. It's not from time machine local backups, because I've disabled those. In fact, it's reporting MORE free space than there should be! In all cases, Disk Utility shows the correct amount. (So does the Terminal command df.)
eg:
external 120GB hard drive (USB) - finder says 137.83GB free (more than the drive can hold, nice) - disk util says 70 used 49.9 free... better
external 1TB (firewire) - finder says 276.66GB free - disk util says 783.72 used 216.15 free
internal 120GB SSD - finder says 108.32GB - disk util says 78.6GB used, 40.5 free
Anyway to fix Finder?

I noticed the same problem. I assumed it was from Time Machine's local backups (which exactly account for the space discrepancy between Finder and Disk Utility on my machine). But, as you say, you've disabled Time Machine local "snapshots." I can only assume you deleted the local backups (to free up the space they were using), emptied your Trash and are still showing the discrepancy.
