Unused disk space

Hi,
How can I see the unused disk space in solaris 9? is there any commands to check the unused disk space in MB or GB?

In that case, its a bit trickier.
you want the format command
run format
select the disk
do 2 "p" commands for partition, print
slice 2 should represent the entire disk.
You need to compare the existing partitions with the entire disk to see whats unused
And then create a partition to contain it.

How to find out the unused disk space?

Hi,
I want to know if there is any way possible by which I can find out the amount of disk space that is available. I have to write an application that checks for the disk space under Windows and Unix platforms. If anything is possible please let me know as soon as possible.

I know that there is no Java API for it. I tried using the Runtime.getRuntime().exec("cmd /c dir") method to find out the available disk space. But it returns the value through the InputStream which would have to be parsed to get the unused disk space value. If there is a way to write a shell script (for Unix / Linux) and a batch file (for Windows), please do let me know of the same. Also please let me know how to execute the script / batch. Awaiting your reply.

Shutdown postponed by message asking if FileVault should recover disk space

Does anyone know how to specify a default preference for handling this message? After selecting "shutdown" and agreeing to "shutdown now", several seconds later, after having walked away from the screen, and then glancing back, I find I am then prompted to answer "continue or cancel" before shutdown can proceed. This is annoying, as I expect the system to be able to shut down after I instructed it to. Further, this message interferes with the system's ability to automatically shut down cleanly when the UPS detects an electrical power failure. Following is the text of the message: Your home folder, which is protected by FileVault, is using more disk space than necessary. FileVault can recover this space. Would you lke to continue? When you click continue, FileVault will recover the unused disk space. Although this takes a while and you cannot stop it, it's recommended that you let FileVault recover the disk space now.
iMac G4 Mac OS X (10.3.9)

Why is it so many of the questions I need answers to, others have asked, but not gotten a solution to either?
The filevault reclaim space warning is very frustrating when combined with Timbuktu. If you attempt to restart a computer remotely that is protected by filevault, and the warning about reclaiming space comes up, you are stuck. The Timbuktu process has already been stopped. I've found that I can SSH into the box, and I can likely kill the process responsible for the reclaim space warning, but it would be nice to just have the box timeout after a few seconds, and default to Cancel.

No Disk space on my BRAND NEW MacBookPro???

While using my Imovie to import clips from my Canon ZR600 First 38 edited clips suddenly moved into the Trash on their own.. and cannot be dragged out without them flying back like on a rubber band.. Now I get this error message that says,"You are running Dangerously low on Disk Space.. If you continue you may not be able to save your project..(which I have already saved I thought), You should immediately delete unused clips from the Trash, or switch to the Finder to delete other files in order to make more space available.." But for crying out loud I haven't even owned this high capacity memory machine more than a few days.. how can this be?? Another error message says I should empty my Trash to acquire more disk space... but I WANT to Restore them.. not delete them.. Very frustrating.. Any help?? Please Advice Thanks Much. I hate to say it, but I NEVER had this kind of problems with my previous 8 Windows machines that didn't have a simple solution.. I hope this problem does as well, or I'm going to be seriously in doubt about the superiority of Apple.. especially given the problems I'm observing that others are having on this board.. TELL ME I'M WRONG..

Hi,
You don't say how long those "..38 edited clips.." are.
Digital Video uses about 13GB of space per hour of video. If you've imported, say, 3 hrs of video, that'd take up nearly 40 GB of hard disc space. On an 80 GB hard disc, that'd be a tight squeeze, taking into account your Operating System, whatever programs and documents you may have - especially if you've loaded it up with pictures and iTunes!
And the Mac OS likes to have about 10% of the hard disc as free space, for swapping items in and out of memory, keeping 'log' files of what it's doing, etc.
If you're going to import and edit lots of video, do what many people do: get a fast external FireWire hard disc to use exclusively for movies, format it as Mac OS Extended (aka HFS+) as soon as you first plug it in - using Applications>Utilities>Disk Utility and clicking the 'Erase tab' - and then you should have trouble-free editing ..oh!.. just thought: Canons don't like to share the FireWire connection with anything else, so you may not be able to 'daisy-chain' your Canon camcorder through the FireWire disc to your MacBook ..in which case, import video to the MacBook, and movie it across to the FW disc.
But first: how long were those 38 clips..?

Free disk space in Finder vs Terminal df command

i am in process of writing a shell script to backup our data.
before starting the backup process, i am checking how much space is left on the disk:
terminal> df -k /my_data_directory/
Filesystem 1024-blocks Used Available Capacity Mounted on
/dev/disk0s2 244781464 173055384 71470080 71% /
this states 71.47 GB free space on /
however, the Finder reports 96.17 GB free space on Macintosh HD (which is also mounted on /).
where does that difference come from? how can i "calculate" the real free disk space?

tuscan wrote:
do i get your answer right:
this means the Finder is reporting an amount of free space one can never use?
its number includes those bytes that are unused in used disk blocks?
e.g. say a block is 8k an my specific disk, and i'm saving a file with 1k of text.
the Finder would report 7k of these 8k as free space?
while df takes the whole 8k block as "used"?
As jsd2 points out, it is more complicated than that. I don't have local snapshots running on my machine but I still have a significant discrepancy, although not as large as yours.
df is a fast tool and only looks at blocks. The Finder does more work and keeps track of file sizes and, apparently, the potential to delete them. But if you had a one-byte file, those other 4095 bytes wouldn't necessarily be wasted. You could write another 4095 bytes to that file without losing any disk space.

Reclaim disk space after delete an index

Hi ,
I have deleted unused indexes from a history table to reclaim the disk space was allocated for these indexes , yet the size on the disk is the same , any steps I can follow to achieve this would be greatly appreciated..
indexes size is 70 GB
table size is 45 GB , # of rows is above 200 Million
Thanks in advance

in order to reclaim space after your big delete. Don't shrink your data files unless you have no other choice.
The space will automatically go back to SQL server. You don't have to do anything.
The database size will be the same plus the growth of your log file due to logging the transactions. However, internally, SQL server knows that it still has that space to play with.
Other wise you can go for update the statistics and rebuild indexes . but I think it would be the part of your normal weekend nightly maintenance plan

Problems saving pdfs in IE "not enough disk space"

After updating Adobe Reader from 9.... to Adobe Reader X 10.1.23 I cannot save a pfd file opened with a browser, wether using Internet Explorer 8 nor the actual firefox. The error message is something like .." not enough disk space" , what's not right!!!
I reinstalled 'Reader X - no solution
I deinstalled Reader X and installed the old Version 9 - saving is no problem!!
What can I do ??? Thanks..

when you make a dvd using dvdsp, you need to build it on a local drive before dvdsp can burn the dvd. So more than likely, .... there's "not enough space" on that drive.
You should always have a minimum of 10% free space on ALL drives and at least 20% free space on your startup drive. Having less space can create all sorts of problems and the data on the drive can get corrupted and unusable.

Excessive use of Disk Space

I noticed today that the Apple Software update is using 452MB of disk space and it appears it's captured every update for iTunes, Quicktime and Safari since I've started to use it.
/c/Documents and Settings/All Users/Application Data/Apple Computer/Installer Cache
/c/Documents and Settings/All Users/Application Data/Apple/Installer Cache
There appears to be no way to purge the cache via the Apple Update Software, but i guess the old-school method works.
Anyone higher than 452MB in their Installer Cache

Thanks for those who replied. The idea was to write a technical paper and write a supporting tool that will list all unused indexes on a Oracle database and list indexes that were used and if so, how they were used and when. I am working on a project basically.
Referencing papers aren't difficult. I can always do that. But we all being DBA's, there are one or the other issues that we would come across in day to day work. If i can reflect any of the real time problems and try to address it in my tool, it would be beneficial for all.
So that was the motto. Also, it's not only for Oracle. I am trying to write a tool that can possibly integrate with other databases such as SQL server and Sybase.
Thanks

Ran out of disk space - 1TB drive

I've run out of disk space for back up with my 1 TB drive I use for TM. The key reason is because of the HD files I am using for my home movies not to mention the media I have been buying off of iTunes.
I have an unused 500GB drive. Can I somehow create a "RAID" drive that can "combine" my 1TB drive and my 500GB drive into 1 drive that TM can use? I know RAID drives can be created using Disk Utility, but I am not sure if this is really the purpose of a RAID drive.
Any insights?
Tony

no.
Although it is possible to create a raid using 2 drives of different sizes, the size of the raid will be slightly smaller than 2x the size of the smallest drive..and you will lose the 'extra' space on the larger drive.
Raids are also better suited for internal drive configurations - that way, you can't accidentally break your RAID by (accidental or intentionally) disconnecting a drive. If you break your raid, you have lost all your data.
Hazard of a 2 drive raid is data loss. Unless you are using 3 drives, data integrity is compromised. (raid with error recovery requires a 3rd drive)

No free disk space on my Macbook Pro- why?

Hi, i'm having a lot of trouble trying to free up disk space on my mac!
I have 120g HD with 8G RAM. I'm using OS X 10.8.5
Disk Usage on Activity Monitor says i have used 110.29G and only 10.18G free, which i find ridiculous! I have backed up my computer with an external hard drive, have deleted all of my unused apps (like Photoshop and some Microsoft office programs), movies, work, and most of my photos to free up space, leaving only photos, music and a few small word files here and there on my computer, yet i still have no space!
'About this mac' shows 62.97G of 'other' storage being used.. what could this be??
I have used apps like Trash It, CleanGenius and AppTrap to free space, but nothing seems to be working! The app CleanGenius enabled me to get rid of duplicate files and i managed to get 17GB free, but after i restarted my computer it went back down to 10GB! Why?!
On Disk Utility i have used the verify disk permissions, repair disk permissions, and verify disk functions but to be honest i don't think it made any difference.
I have used terminal to free cache's and clear the sleep-mode file that the mac makes.
Any suggestions would be fantastic as i don't understand why i still don't have any space!! I've been trying for weeks! Fr
Please help!!

Issue 2: Not enough free disk space

Well, now that I'm here, I will try to figure out all my problems.
Ignoring the fact that my MacBook won't turn on, once it goes back to normal, I hope I can solve another thing. Two or three times, while I've been working in heavey Word documents in my Macbook, a message box appears when I click on save or when it tries to do "Autorecovery". It says there's not enough free disk space for me to save that file. What I do every time is I select all, then copy and then quit word. I open it again, paste and save. Everything is fine, but I'd really like to know *** is wrong since I do have a lot of free disk space and this doesn't happen unless it's a heavy file in word. Should I get rid of some apps? Unused files? I don't have that many... I think my Macbook is acting weird since I've almost got nothing stored in it but files, pictures and songs. Any ideas on how to prevent this from happening again?

Get Info on your hard drive or open a finder window and see how much space is available on your drive - that's at the bottom. Music, pictures, movies use more disk space than most files. You might have enough space sometimes because various programs - like Safari - cache material and the caches can get large. Some caches empty themselves and others need to be emptied; you can empty the Safari cache from one of the menus.

Disk Space not restored after deleting iphone backup

Hi,
Today while restoring my iphone i realised that itunes had made multiple copies of ~3gb of my iphone data. Since my iphone was restored successfully I decided to remove all the backups and make a fresh new backup. After deleting the multiple backups I found that my available disk space had not increased at all. I even went to ~/Library/Application Support/MobileSync/Backup and ther was nothing in there. So I went ahead and made a new backup which consumed additional ~3gb. And just to test if it was only itunes that was doing this I deleted my photos from iphoto ~5gb and even that did not give me back my 5gb. I went to trash and I dont have anything there.
So, here I am confused as to where my deleted stuff is going to because it does not seem like its getting deleted.
Anything that i can do get my space back?
Thanks,
Yogi

Local snapshots are hidden copies of files that have been changed or deleted in between Time Machine snapshots. They are stored in free space that would otherwise be unused, and therefore wasted. The space occupied by the snapshots is managed automatically. When free space starts to run low, the snapshots are deleted. The Finder reports the space occupied by local snapshots as "Available," which it is.
If there are unwanted changes to your files in between Time Machine snapshots — which may be far apart when you're moving around with a portable computer — you may be able to revert the changes from a local snapshot. If you disable local snapshots, you lose that protection, and you gain nothing. There is no offsetting benefit whatsoever; merely added risk.
Empty storage space is simply wasted. You paid for it to be there, but it's doing you no good at all. Local snapshots put it to use.
Very rarely, if ever, you might need to delete the local snapshot store in order to add a large amount of data all at once. If that need ever arises, which it probably won't, all you have to do is turn Time Machine OFF in its preference pane, and then turn it back ON immediately.
You should ignore the bad advice that circulates on this site to disable local snapshots permanently by running a shell command. If you ran such a command, ask for instructions on how to reverse it.
