RAID 5 - available space?

Hi all,
I just got a Mac Pro with four 2TB drives and migrated them to a RAID 5 setup. In the RAID utility, it says that the total available space would be 5.23 TB, which sounds right given the research I've done about RAID 5 setups and available space. However, on my desktop, it shows the Macintosh HD as a RAID icon, and when I click to get info it says only 2TB as total space, as opposed to 5.23TB.
Where do the other 3+ TB show up? Am I missing something?
Thanks for any help!

Available space on firewire 800 graid incorrect

I have been working in FCP 4.5 HD for the past year and a half. The drive in question has been with me through the worst of it.
It is a 500 GB g-tech raid Firewire 800 drive. When I Get Info on the drive, Mac OS 10.4 tells me it has 68.19 GB of available space. When I get summary info for the drive's entire contents, it says it is 308.53 GB. With an actual capacity of 465.65 GB, the math doesn't add up. 465.65 - 308.53 = 157.12
I've got the same drive with the same media on it on another system and the "Available space" is what I would expect it to be. I've run disk utility and disk warrior (to rebuild the directory) on the drive, and it's always the same.
I though it might be a fragmentation issue, but since mac os defragments as it goes, I'm not quite sure what to hypothesize.
Any ideas?

i was afraid some one was going to say that. I ran disk warrior. I haven't worked with it extensively, so if it goes beyond just rebuilding the directory or scavenging for lost files, I wouldn't know how to specifically target the catalog & b-trees.
I'm afraid this might be a backup and reformat situation.
I appreciate the input.

The size of your selected options exceeds the available space

I am trying to install a brand new full version of Adobe Creative Suite 4 Web Premium.
I am unable to proceed, as the install options window tells me "The size of your selected options exceeds the available space" with a red exclamation point.
It says my options require 9.6GB of space.
I am trying to install on my D Drive, which has 1.1 TB of available space. Yes, that's right, Terrabytes.
Help!
System: Intel Core2 Quad Q6600 @2.4 GHz, Windows Vista Ultimate 64 bit SP1, 4 GB RAM, system drive WD Raptor (75GB) and main drive (where I am trying to install CS4) is (6) 500GB seagate SATA hard drives in a 2.5TB RAID 5 array. Motherboard is a Gigabyte GA-P35-DQ6 and video is an Nvidia GEForce 8800GT (512 RAM). RAID controller is onboard the motherboard (Intel ICH8R)

SOLVED!
Bob and Peter, you nailed it.
I had inadequate room on the C drive...I was down to only 5 GB of space.
I cleaned up the desktop (The wife thinks that is a great place to store everything) and freed up my C drive so it had just over 10 GB of free space, and the red exclamation point went away. It is now happily installing onto my D drive.
Ian, my C drive (system) is a Western Digital Raptor...10,000 RPM. They are really small (75GB) but really fast so that windows boots up really quick. It is a performance thing. My D is a RAID array for redundancy...as I cannot afford to lose my pictures, videos, and documents, etc. - and I always keep my program installs on D so as to keep the C drive speedy and un-cluttered - plus if and when windows gets corrupted (which it does once every couple of years for some reason), I can re-do it in 5 minutes with an image using Acronis True Image.
Thanks to all of you for your ideas, and I am glad I got it solved. If any Adobe employees read this...you can at least throw in some nice paper manuals for the software. When software is $1600.00 I'm not real concerned about saving another tree - and you shouldn't be either...I'd rather have some paper manuals for reference when I buy a full retail package. So pump up the packaging please. Thanks!!!!

Question: Inconsistency in Icloud between total and available spaces.

Dear all,
First of all, thank you for read this topic and please kindly give me information or advise if you can.
Right now, my Iphone 4s was reset accidentally and all data were gone without any backup in Itune but I thought I have backup some in Icloud. After it was reset, I tried to restore with Icloud but nothing was found. Then, I came back to check space in Icloud (setting > Icloud > storage & Backup) and found that total space is 5.0 GB but available space is 355 MB, meaning that space around 4 GB are used for backing up something. So, this point is so strange. Icloud said nothing was backed up but my Icloud space has been used for 4GB.
Could anyone advise for data backing up and answer this problem for me?
Also, please kindly let me know how can I get storage 4GB back.
Thank youso much in advance,
Yong

You have data corruption. restore your phone and set it up as a new device. Not from backup

What happens when an iPod is synchronized with an iTunes library that is bigger than the available space on the iPod?

What happens when an iPod is synchronized with an iTunes library that is bigger than the available space on the iPod? I did this some time ago. On screen was shown available space somewhat less than 120 GB, but maybe somewhere between 10 and 20 GB more in the library. I had to get the iPod updated anyway, so I did proceed. However, afterwards the total content of the library was only about 110 GB. Now I wonder what did actually happen. Was the first sign only corrected for double copies of the same files or lost files or where files deleted from iTunes? And if files where deleted from iTunes, were they also deleted from my computer?

Same as you would if you bought a pc; copy everything from your old computer to your new one. Then you can just sync everything from the new computer, as you did with the old one.

Why is there so much available space on my hard drive after installing Lion?

I just made the decision to go ahead and install the new operating system "Lion"
I backed everything up to my Time Capsule and I have an older back up of everything on an external hard drive.
Now I have two questions and one task.
Why is there so much available space on my hard drive and where did my iPhoto library go after installing the new operating system?
My task is to restore my most up to date iPhoto library which I assume is on my time capsule.
How should I approach this task?

Hi entresoft,
I am not sure how to do this. I am not a very literate computer person but have a vague idea of what you are suggesting.
If I do manage to figure out how to do what you have suggested will this restore my iPhoto Library and I assume maybe other files?
Thanks!

Hard Drive Capacity Issue -- 51 GBs missing btwn utilized and avail space

I have a 200MB internal hard drive.
My SYSTEM PROFILER states:
Capacity=185.99GB (which I understand due to system use, etc)
Available= 26.25 GB (odd)
This available space reading seemed odd as I don't have much data on the HD (transferred files using Migration Assistant from a 80gb, 1.67ghz older G4 laptop).
So I went to the ACTIVITY MONITOR and looked at DISK USAGE at it states:
Space Utilized= 99.14 GB
Space Free= 25.85 GB
With a total of 124.99 GB between the two (the adjacent pie chart total)
MY QUESTION: If I have a HD with a capacity of 185.99 GB, with only 99.14 GB utilized, why is the space free missing 51 GBs? Where did this memory space go?
Note: I have never partitioned the Hard Drive or created any sort of RAM Disk.
Anyone? Please help.

UPDATE BUT STILL NO ANSWER:
Ran DISK UTILITY which fixed some minor errors and how states "Volume Macintosh HD appears to be OK"
But the issue remains - I have a 200GB hard drive but the data at the bottom of this utility reads:
Capacity : 186.0 GB (199,705,673,728 Bytes)
Available : 26.3 GB (28,291,375,104 Bytes)
Used : 98.6 GB (105,916,047,360 Bytes)
Number of Folders: 173,085
Number of Files: 886,070
HOW CAN I ONLY HAVE 26.3GB available when I have only used 98.6GB of 186GB = Should be a 87.4 GB balance available, not 26.3 GB, right????????
What is the deal here? Is this related to MobileMe or iPhone issue maybe?
The hardware start-up test and disk utility test are all clean. Someone? Anyone?
Thanks!

Verbatim disk drive historically used only for time machine backups. Recently i added some other media files to use some of available space without partitioning, the disc now refuses to mount in finder despite appearing in disk utility. Repair fails. HELP

Sorry to elaborate a bit more.
I have used time machine since owning my mac book pro with no issues. i keep the timemachine backups on an external hard drive made by Verbatim. This has not external power source.
Recently i decided to use up some of the available space on the external verbatim disk drive to store some movie files which were sitting on my macbook pro.
Therefore i created a new folder outside of the time machine backup folder and stored the movie files in there.
From then on Time machine failed... and a few days later i noticed it was not mounting in 'finder'
Therefore i used disk utility to see if it was recognising it. Which i was. However when i try to repair it the repair process fails.
In disk utility i am presented with 1 TB Samsung HN M10 which has a child called Verbatim HD.
The 1TB Samsung hardware appears fine, but the verbatim disk i am unable to fully verify and fix.
Does this mean i have lost all my back ups?
Have I lost all the media that i put on there?
Is there any way to fix this?
Any help would be appreciated.
didier07...

To summarize: You used an external Verbatim HD for your TM backups. Then, you stored some movie files on the "spare" space on the Verbatim drive. Now, Disk Utility isn't being recognized, and repair is disabled. Your home Samsung drive is working fine, but the Verbatim cannot be verified.
The problem, I believe, is that the external Verbatim drive wasn't partitioned. There should be two partitions: one for TM backups, the other for video. That way, you can perform backups, and still retain some space for video or somesuch.
Frankly, I don't know how to fix this except through the following. (1) Erase the Verbatim drive, (2) Create a new blank space and format it, (3) Make two partitions - one for backup, the other for video. (4) Run TM through one partition, but switch to the other for your videos. The better solution might be to have one dedicated drive (perhaps the Verbatim) for backups, and another dedicated drive for video backups; that way, you'll have plenty of space for expansion.
I hope someone will correct me if I'm incorrect, but I believe you've essentially lost your backups and media. I don't know how you can retrieve that clump of the now-undifferentiated data on the Verbatim drive. To retrieve any lost data, you're going to require another external drive that's larger in capacity, as well as data recovery software; don't expect encouraging results. If you're desperate, there are firms like Drive Savers that can offer a more comprehensive solution - at a cost.

HT5318 Ever since I updated what looked like iTunes 10.6.1 my computer has been corrupted with Malware, which has filled up all available space on my hard drive. What do I do to get rid of the Malware?

Ever since I updated what looked like iTunes 10.6.1 my computer has been corrupted with Malware, which has filled up all available space on my hard drive. What do I do to get rid of the Malware?

First, reboot. That will temporarily free up some space. According to Apple documentation, you need at least 9 GB free for normal operation. You also need enough space left over to allow for growth of your data.
Use a tool such as OmniDiskSweeper to explore your volume and find out what's taking up the space.
Proceed further only if the problem hasn't been solved.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To really see everything, you have to run it as root.
First, back up all data if you haven't already done so. No matter what happens, you should be able to restore your system to the state it was in at the time of that backup.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.
After installing ODS in the Applications folder, drag or copy — do not type — the following line into the Terminal window, then press return:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
I don't recommend that you make a habit of this. Don't delete anything while running ODS as root. When you're done with it, quit it and also quit Terminal.

External hard drive has no available space even though i have deleted nearly everything on there

I have an external hard drive for backups and it has no available space even though i have deleted nearly everything on there. Where is the space?

Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.

Find available space in buffer cache

Hi.
I want to find available space from buffer cache. First thought was to make it 8i-9i comp, by not using v$bh to calculate sum of memory and available space.
I have the following pl/sql block to calculate the values:
declare
num_free_blck integer;
num_all_blck integer;
num_used_blck integer;
overal_cache number := 0;
used_cache number := 0;
free_cache number := 0;
blck_size integer;
pct_free number := 0;
begin
select count(1) into num_free_blck from v$bh where status='free';
select count(1) into num_all_blck from v$bh;
select count(1) into num_used_blck from v$bh where status <> 'free';
select value into blck_size from v$parameter where name ='db_block_size';
used_cache := (blck_size * num_used_blck)/(1024*1024);
free_cache := (blck_size * num_free_blck)/(1024*1024);
overal_cache := (blck_size * num_all_blck)/(1024*1024);
pct_free := ((free_cache/overal_cache)*100);
dbms_output.put_line('There are '||num_free_blck||' free blocks in buffer cache');
dbms_output.put_line('There are '||num_used_blck||' used block in buffer cache');
dbms_output.put_line('There are totally '||num_all_blck||' blocks in buffer cache');
dbms_output.put_line('Overall cache size is '||to_char(overal_cache,'999.9')|| 'mb');
dbms_output.put_line('Used cache is '||to_char(used_cache,'999.9')||' mb');
dbms_output.put_line('Free cache is '||to_char(free_cache,'999.9')||' mb');
dbms_output.put_line('Percent free db_cache is '||to_char(pct_free,'99.9')||' %');
end;
The result of the execution is:
SQL> @c:\temp\bh
There are 3819 free blocks in buffer cache
There are 4189 used block in buffer cache
There are totally 8008 blocks in buffer cache
Overall cache size is 62.6mb
Used cache is 32.7 mb
Free cache is 29.8 mb
Percent free db_cache is 47.7 %
PL/SQL-prosedyren ble fullfÃ¸rt.
SQL>
This is not correct according to the actuall size of the buffer cache:
SQL> select name,value from v$parameter where name='db_cache_size';
NAME
VALUE
db_cache_size
67108864
SQL>
Anyone that have an idea bout this?
Thanks

Provided the OP figures out that xx_bh is probably a view defined by sys on top of x$bh this will get him the number of free buffers - which may be what he wants - but apart from that your query is at least 10 years short of complete, and the decode() of state 3 is definitley wrong.

Other using all available space after update to iOS 8.3

Before updating I had at least 10GB of free space, but ever since I updated to iOS 8.3, I am repeatedly receiving the Storage Almost Full error. The last couple days I have deleted 2 or 3 GB of data and apps to free up space, but the error returns the next day and I have no space available even though I haven't added anything that would take up that much space. Looking at apps under Manage Storage, there is nothing taking up the space that was previously unused. When I plugged my phone into iTunes, is says that Other now takes up more than half the available storage on my phone, and I have the 64GB model.
Other had previously taken up quite a bit of space, and I know that this is mostly documents and data from my applications and messages, but there's no way it should have jumped so dramatically in size. It seems to be just growing to take up whatever available space there is on my phone.
