How should i partition my HD?

i have 250 Giga
i already have a partition for windows (20G)
to make 1 big partition?

/var -> this partition is for the package you download?
pacman stores its package database in /var/lib/pacman and caches the downloaded packages in /var/cache/pacman/pkg. Also the sources for packages built with makepkg are stored by default in /var/cache/pacman/src.
10gb should be more than enough for this. I created an own partition for it because i wanted to use reiser (which makes pacmans db access faster on my machine) and ext3 on every other partition.
/opt - > you said you using it for games, why won`t on /home?
Of course you can store your games in your /home... Its just a matter of preference, and i prefer to have no apps/games in my /home but use /opt for that and chown the games to my user where its required. Planeshift for example has an internal updater, so you need to have the proper rights...
/boot -> for what is it needed?
I never used a boot partition so far so i cant tell you that much about... AFAIK its used when you use a more exotic fs like xfs/jfs that cannot be read by grub for your root partition. The boot partition is usually ext2 for maximum compatibility and gives you the ability to boot from filesystems that are not supported by your boot loader. There may be more advantages, but i dont know them
and what about ext2/4 why not using it?
ext2 has no journaling, so your data is not as safe as compared to ext3... ext4 is in development and unstable, and as far as i know you cant use it with archs installer yet...
As said, its all a matter of preference and how you like it. The minimum i would suggest is a separate /home partition...

How should I partition data across 2 hard drives to make for less latencey?

Hello all!
I am using a Dual 2.7 G5 Power Mac and I just bought the Hitachi 500GB internal hard drive to supplement the stock 250GB drive that came in the tower. I mostly want to orient my computer for the needs of a home recording studio. I am Logic Pro user and I want to streamline data retrieval as efficiently as possible.
Now, I also have a good deal of other junk on my computer (video and iMovie projects). I would love an organization solution on how to partition everything that I have filled my 250GB drive up with across both hard drives. I'm aiming for a solution that will be good for the long-term as I continue to add more and more stuff (audio/music related and non) onto my hard drives.
Here are a few of the primary concerns which have held me back from just diving in:
I have several DVD's worth of audio samples (for use with software sampler) that I have yet to load onto this computer. Should I load/move all of my samples onto the secondary 500GB drive or would the streaming retrieval of all of that content from the secondary drive add extra latency and slowdown when the host application running these tasks and retrievals is ran off of the primary drive (the 250GB drive on which the OS is installed)?
Or should I just move Logic to the secondary 500 GB drive as well as all of the audio samples and run all things having to do with audio production off of that secondary 500GB drive? Would running such a CPU intensive app from the secondary drive make a performance difference compared to running it off of the primary drive? Does it matter whether or not a program is run off of the hard drive where the OS is installed?
Or should I find a way to have all apps running from the primary 250 GB drive WITH all samples (streaming and non-streaming) also on that drive and just have my project files and audio recording sessions (which eat up large portions of space) located on the secondary 500 GB drive? Or would I run into a noticeable latency with having the recorded audio sessions ran off of the secondary hard drive when I am running the application that retrieves them (Logic) off of the primary drive?
Where do I put my pro apps? Where do I put my audio samples (mainly for EXS24, SampleTank, and BFD)? Recording sessions? Everything else?
Please, experienced users, what should I do to garner the best performance out of my Mac?
Thanking everyone in advance,
Matt!
P.S. I am running OS 10.4.6 and using 4.5 GB of memory.

Thanks you guys. X, that is interesting to read. Chap, I see what you are saying. But I just found these two FAQ's from BFD's website. How do you feel in reference to them? Is it me, or do these questions somewhat contradict each other? :
Is it a good idea to put BFD on its own partition on my audio drive? [top]
In general, no. If your harddrive is partitioned and you are streaming from both the BFD partition and your own tracks, this will lead to the hard drive read head jumping back and forth between the two partitions, which may reduce performance. Also, if you are streaming non-BFD audio from the same drive, this reduces the bandwidth available for BFD streaming.
On which hard drive should I install my BFD data? [top]
FXpansion recommends, in order of performance preference (first is best):
1) A dedicated SATA or IDE internal drive, 7200rpm or above
2) A dedicated external firewire drive (do NOT chain the firewire drive with a digi002 or other firewire audio interfaces!)
3) A dedicated external USB2.0 drive
4) An internal drive shared with the data from other heavy disk-accessing programs, eg the operating system (virtual memory swap files), or another disk streaming application such as your host sequencer (audio tracks) or Kontact etc etc.
Power Mac G5 Dual 2.7Ghz 2.5gigs of RAM Mac OS X (10.4)
So it sounds like they recommend BFD having its very own hard drive. I dont have the resources for that right now. So I wonder what would be better: Sharing the OS drive with BFD as mentioned by X and used as the last resort from FAQ #2, or split my second drive via partition into Samples (including BFD audio) and Storage for projects and raw, recorded audio sessions.
If only I wasn't such a perfectionist. I would get so much more work done! Thanks again guys. I am indebted.

How should I partition 10 gig HD for Mail Server???

I plan on making a mail server but I am not sure what partitions to use. I have a 10 gig HD, and I dont want to partition it wrong then have no idea how to go back and redo the partitions without reinstalling. I was thinking something like:
/ = 2gig
swap = 512mb
/opt = 3gig
/export/home = 4 gig
Any idea what steps I should take first to creating a mail server? I still can't find the pop and imap server packages.

For POP3, I suggest qpopper from Eudora. www.eudora.com/qpopper.
It virtually installed itself and seems to work fine right from the start. Now if I could only figure out how to get Sendmail to work with SMTP. All my Internet mail gets refused by Sendmail, incoming and outgoing.

How should I partition my server? There's 3 hdds.

Finally getting a server setup from an old amd sempron 2ghz 1.5ghz ram computer. There's three hard drives in it, 10gb, 20 or 40gb and a 250gb. Should I make the 10gb my / partition, the 20/40gb my /home and the 250gb the /var or what?

Well for starters, what are you going to use this server for?
Personally, I'd create an LVM Logical Group from the 10 and 20/40gb drives and use them for the system with the following mount points:
4gb /
2gb /var
2gb /tmp
4gb /usr
128mb /boot
Then a second LVM Logical Group with just the 250gb drive and use that to create your /home, /data, /srv, /whatever

How should I partition?

Hi there. As I type these words I am installing OS 10.3 on my Imac 700MHz G3 60Gig hard drive. At no time during the installation was I asked to partition the drive. I have some OS 9 applications that I would like to run. Why wasn't I prompted to partition and when I finally do partion, what size volumes should I use? Thanks! Al

Hi Alfred_J;
May I ask for what purpose do you want to partition the hard drive.
Generally it has been my experience that partitions are more of nuisance then a help. So unless you have an extremely good reason for partitioning the hard drive, I would recommend that you don't do it. Leave it as is.
Any more disks are so cheap that rather then partitioning most everyone is simple getting more disks.

How should I partition a new hard drive - for data storage

My original drive was failing, so I installed another one, with the operating system on it, so that when that one failed, it was not a problem. Now I have a 2nd one that's failing (or has possibly failed, though I do have it backed up using Time Machine . I bought another drive today - a 2 TB one and want to install it, possibly partitioning it - maybe with a partition that holds the operating system and some of the software, (though don't know if that's a good idea or not), and part for the data backup of videos I've made, and slideshows from Aperture, etc. - just "stuff". What is the best way for me to partition it?

Unless you have very specific requirements, such as wanting to install more than one OS, there's no advantage to creating multiple partitions.

How much should I partition for Time Machine/Backup?

Hi all,
I upgraded my PB G4 HD to a 160GB recently and have just purchased a 1TB External HD. How much should I partition in the external to be used for Time Machine backup purposes of my internal HD? Will the same size suffice, or should I allocate more?
Also, I was thinking of formatting the drive so that it's both Windows and OS X friendly, but that means formatting it to MS-DOS something (I was just reading about it in another thread), will that cause any issues for the partition for Time Machine that I created? Thanks.

That's not practical. If you want to use the hard drive on a Windows machin while still being useful for Time Machine you should use MacDrive.

I would make the partition at least twice the size of the internal drive. Preferably, you would want 50 GB for a Leopard install that includes just the base operating system so you can boot off the 50 GB to recover your Time Machine data if your Leopard installer disc ever becomes unusable.
Also since you have a Powerbook, your 1 TB hard drive should be Firewire. USB will not boot Powerbooks. If it is USB only, you can remove the external hard drive case and replace it with one compatible with the drive inside that case from http://www.macsales.com/ that has Firewire.

Cloning TC backups to external HD with data on it already - should i partition the HD? How to do this safely?

hi. i found a discussion directing how to clone backups onto a HD for proper backup transfer. what it didn't anwer for me, was something else. i have data on the HD i am trying to use as a temp destination for my TC backups. Should i partition the destination drive and have my old data on one volume - TC backup on the other? please help if you could with instructions on how to do it safely without distroying my data! THANKS A BUNCH!
OS mountain lion, 1st gen TC, 500gb, destination HD - WD passport for mac, 1tb.

Yes. Time Machine works better if it is in total control of its storage space.
Of course partitioning the drive in a Time Capsule is only possible by removing it and doing the partitioning on another computer.
If this were mine I would get another external drive and connect that to the Time Capsule. Move your data to the new external and allow Time Machine to use the whole internal drive in the Time Capsule instead.

How should I reformat my external hard drive?

I have just purchased a new 21.5" iMac and I will be moving from PC to iMac. I currently have a 2.5TB external hard drive which I have connected to my PC laptop that I use to store and watch movies. My question is how should I format/partition my external hard drive so that I can use it with my new iMac? The external hard drive will solely be used with my new iMac (it won't be connected/used with my laptop again) and I am ok with losing the data on the external hard drive as I have backed up the data currently on it onto another hard drive. I have tried to research what format to use but I am a little confused as to which one is the best and I am looking for some advice.

Old Macbook to New Macbook Air Transfer but new Macbook Air has less Storage Space. I only want to keep all iTunes and iPhoto Files. I can keep the rest on an External HD. How should I do this?

Bought a New Macbook Air and wanting to transfer only iTunes and iPhoto stuff to the new Macbook Air. How should I do this? Ive got and External HD acting as Time Machine but the Data on there is 143G worth and the New Macbook Air is a 128G HD. So i dont need all the extra Documents but want to keep them on the External HD which has been Partitioned.
Question is - How do I transfer the iTunes and iPhoto info into the New Macbook air and keep all its settings ect and also keep the Docs ect in the HD? Time Machine wont work as there is too much info for the New Macbook Air.
What should I do?

In iTunes 11 uncheck the preferences setting in in the iTunes Preferences panel "Advanced > Copy Files to iTunes Media folder when adding to Library"

How to best partition an external drive for my purposes?

Hello, please help,
I've just bought a Western Digital 'My Passport' 320Gb USB (no firewire) portable external harddrive for backing up my data prior to iMac repair.
I also plan to totally wipe my PPC iMac and reinstall it with Leopard.
I erased the external HD, zeroing out the data from it's previous owner, and reformatted it as Mac OS Extended (not journaled).
Now I realise that it might be even more useful than I'd imagined.
I'd now like to partition it so I can use Carbon Copy Cloner to create a bootable copy of my entire iMac while using the rest of the drive as a separate partition for just backing up data.
Ideally I want to be able to use the drive on both Intel and PPC Macs and even PCs, is this possible? How should I format the drive to achieve this?
I've heard I should format it as Mac OS Extended (Journaled) HFS+, what ever that is
I'm currently running OS 10.4.11 but plan to buy Leopard and install that after the wipe.

17" 1.9Ghz iMac G5 (iSight)

Ideally I want to be able to use the drive on both Intel and PPC Macs and even PCs, is this possible? How should I format the drive to achieve this?
For what you want to do, there is a mismatch between your PPC computer and the external drive that you bought.
With a few exceptions, a PPC Mac requires a firewire external drive for booting and will not boot from a USB drive, regardless of which OS is installed and regardless of the partition scheme and volume format on the drive. I also have an iMac G5, and mine will not boot from USB.
If you do exchange your drive for a firewire drive, do not get another Western Digital model to use with your G5 - many external WD firewire drives will not boot a PPC mac. See [this page|http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/stdadp.php?pfaqid=1787]
If you want to keep your present USB drive, you can still partition it with one partition for a backup clone and another for "other stuff". With respect to immediate use for recovering your stuff after a clean Leopard install on the HD, I think that Migration Assistant will still work, though I haven't tried this. As for the future, the problems with a clone not being bootable are 1) You can't test it to see if it works OK, and 2) If you do need to restore from it you'd need to boot from "somewhere else" - I think you could boot from an install disk and use Disk Utility's Restore feature to clone it back.
With regard to PC access, a PPC mac normally requires an Apple Partition Map partition scheme on the drive for booting, and such a scheme does not allow for the FAT32 volume format that is readable by PCs. However in this case since your PPC mac can't boot from it anyway, you could partition the drive as GUID. This would allow the main volume to be formatted as Mac OS Extended (Journaled) for the nonbootable clone, and would allow the extra volume to be formatted as FAT32. If you eventually got an Intel Mac, a clone from it to the main volume would also then be bootable.
But what I would do, if feasible, is exchange the USB drive and get a non-WD firewire drive instead.

How to use partition by instead of group by?

Hi,
I am having trouble using partition by clause in following case,
column other_number with null values contains 10 records in 'some_table'
5 records with date 11-01-2009, item_code = 1
5 records with date 10-01-2009, item_code = 2
This query returns all 10 records, (which suppose to return 2)
SELECT count (a.anumber) over (partition by TO_char(a.some_date,'MM'), a.item_code) AS i_count, a.item_code,
TO_char(a.some_date,'MM')
     FROM some_table
     WHERE to_char(a.some_date,'yyyy') = 2009
     AND a.other_number IS NULL
Works fine if I wrote like this,
SELECT count (a.anumber) AS i_count, a.item_code,
TO_char(a.some_date,'MM')
     FROM some_table
     WHERE to_char(a.some_date,'yyyy') = 2009
     AND a.other_number IS NULL
group by TO_char(a.some_date,'MM'), a.item_code
How to use partition by in this case?

Hi,
Almost all of the aggregate functions (the ones you use in a GROUP BY query) have analytic counterparts.
You seem to have already discovered that whatever values are returned by
an aggregate funcition using "GROUP BY x, y, z" can also be found with
an analytic function using "PARTITION BY x, y. z".
Aggregate queries collapse the result set.
The aggregate COUNT function:
SELECT    deptno
,         COUNT (*)   AS cnt
FROM       scott.emp
GROUP BY deptno
;tells how many of the 14 employees are in each of the 3 departments.
So does the analytic COUNT function:
SELECT    deptno
,         COUNT (*) OVER (PARTITION BY deptno)   AS cnt
FROM       scott.emp
;but the first query produces 3 rows of output, the second query produces 14.
You could get 3 rows of output using the analytic function and SELECT DISTINCT , but it's inefficient.
Which should you use? Like so many other things, the answer depends on what data you have, and what results you want from that data.
If you want collapsed results (one row per group), that's a striong indication that you'll want aggregate, not analytic functions.
If you want one row of output for every row in the table, that's a strong indication that you'll want analytic functions.
If you have a particular question, ask it. Post some sample data and the results you want from that data, as Rob said.
There is another important difference between aggreate and analytic functions: analytic functions can easily be restricted to a window , or subset, of the data set. This is something like a WHERE clause, but a WHERE clause applies to the whole query: a wondowing condition applies only to an individual row.
If you need to compute a SUM of rows with an earlier order_date than this row or an average of the last 5 rows, then you proabably want to use analytic function.

Should I partition a table or not???

I have a table with well over 8 million records and growing around 15,000 records daily. It is queried through a form (forms6i), no updates are done on the form just "select". The indexes are set up for the 2 types of querries mostly performed- by a date criteria and an id criteria. Is indexing good enough? I notice that it is getting harder to get results from date specific querries. What is the best approaches to ensure the table is optimized for querries? I am not used to working with such a large table size. Does partitioning help indexes work more efficient? Should I run statistics on the whole table?? I am not comfortable running statistics on the table when I am not around to monitor the performance on the server. The database runs 24 hours, 7 days a week- there is no real "downtime" to run stats.
Please advise, I would like to find a best practice approach.

Posted: Jun 19, 2007 11:59 AM in response to: user542952 Reply
(small correction in my earlier posting)
mostly performed- by a date criteria and an id criteriaPartitioning NOT always imporves performance. It can degrade performance if you had NOT partitoned based on queries those hit.
Beaware of local indexes. You might degrade performance because you may need to proble mulitple index partitions.
Do you query date and Ids by range search or exact search ?.
How much data (roughly 10% ,20% , 1% etc..) you fetch through the query

How should a 3 TB WD Elements drive be formattet!

Hi.
How should a 3 TB WD Elements external drive be formattet for my Mac Pro! I seem to remember somebody said only with Guid
the drive will be properly recognized? Thank you for any help.
W.W.

Yes. Do this:
Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
If you are preparing an external or a non-startup drive, then 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. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, 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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
