I am way new to Linux and am getting thrown into the deep end. My company is rolling out a Linux environment to support an application we are using. We are using RHEL for the OS. Does anyone have any recommendations for partition sizes?From what I can tell that appears to be the default values if you do a 'wife install' (yes, yes, yes, yes, yes) on RHEL.

Usually I prefer to keep my operating system on a small partition (50 gigs or so), with the rest of my system on another partition. Normally, with windows (don't flame me for saying the W word!) a small OS partition makes sense.... this way i can scan for viruses, or defrag quickly-- two non issues with linux openSUSE. (with windows, i never install programs on my C: either; this keeps the OS partition small)One advantage at least on windows, with having a small operating system partition is that it's really easy to backup & restore. If my system gets wiped out, I only lose the OS and if i have to re-install, all my personal files are still there.
Is This Done for Me Already With the Default openSUSE Partition Set-up?I just got a new 1TB Seagate HD, which I'm going to use for development purposes in the openSUSE environment.I'm wondering if I can somehow apply my methodology explained above to openSUSE (or if it even makes sense). Are the default LVM partitions ideal for a clonezilla back-up? (can I just backup my primary partition, on the second partition somewhere in case I really mess up my machine). I've been using openSUSE for just a month now, and I'm really liking it (its my favorite linux OS now).
I'm running the installer, and "Guided Partitioning" selected partition sizes I'm not completely happy with. I selected separate partitions for /home, /var, /usr, /tmp etc, and by default it gave me only 5GB for the /usr partition. I'd like to take some space away from /home and give it to the /usr partition, but I can't figure out how to do that using the menu options available.
View 7 Replies View RelatedI have a few partitions on my hard-drive, one for Ubuntu, one for Windows 7 and another for general data storage. When I installed Ubuntu, I was presented with a GUI which allowed me to easily reassign storage space from the latter two to create the former. Is there any way to get to something similar, from which I can adjust the proportions of the partition sizes, without affecting their content?
View 1 Replies View RelatedI plan on installing Ubuntu 10.04 and it will be my first Ubuntu install. I plan on dual booting with windows 7 and I would like advice on partition sizes. I have a 250 GiB drive and my planned partitions are as follows.
Sda1 (PQSERVICE) 12GiB This was pre-installed should I delete it
Sda 2 (System Reserved) 100MiB This was also pre-installed should I delete it
I know one of the above is the windows recovery partition but I don't know which one
Sda 3 (Gateway) 25 GiB This will contain windows will 25 GiB be enough
Extended partition
Logical 1 10 GiB / the main Ubuntu partition 10 GiB should be enough
Logical 2 1 GiB /home this will just hold settings so 1 GiB will be enough right?
Both above partitions are ext3
Logical 3 3 GiB swap partition I have 1 gig ram upgradeable to two
Logical 4 180 Gib shared NTFS partition
I am new to Ubuntu and would like to know if you think this is proper. I have already defragmented the hard drive and will make the partitions in Gparted on Ubuntu live test from usb drive.
I presently have an Ubuntu server 64-bit running VMware Server 2.0 in a test lab. The server was created using the default partitioning method during the installation. So I have what I think is just one huge 300GB partition along with what I hear is a uselessly large swap partition.
I keep reading that theres an advantage to creating dedicated partitions, especially for the the VM datastore.
If the advantages are true then I would like to re-partition the drive.
What partitions should I define and how big should the be?
I have a rack of four 1TB drives all partitioned identically with three primary partitions. On each drive
- the first partition is only 64MB;
- the second is a large 900GB partition and
- the last holds all the remaining space
mdadm has been used to set up
/dev/md0 - RAID1, comprised of /dev/sda1 and /dev/sdb1
/dev/md1 - RAID5, comprised of /dev/sda2, /dev/sdb2, /dev/sdc2, /dev/sdd2
/dev/md2 - RAID5, comprised of /dev/sda3, /dev/sdb3, /dev/sdc3, /dev/sdd3
OK, so it was a silly mistake to make - but I am now need to increase the size of /dev/md0. My thinking is to reduce the size of md1 so that I can grow md0.
On md1 I have two logical volumes. I've successfully reduced the size of the volume so that I can reduce the size of md1. Now I'm at the nervous stage; I can find little written on the topic of shrinking RAID5 arrays - and even if I do this I'm unsure if I can move partitions around to regain the space I so desire.
I've been using Linux for about 15 yrs.. and this is driving me crazy.My daughter often plays on my linux box - a kinda-fresh f12 install.. running gnome.SO one day I go on my computer and my icons on my desktop are as if she changed my display to 800x600 - since the icons are so huge - but web browsing & once i open an application the sizing is fine.Wondering what she may have done to make my icons so huge.i can't seem to figure out any settings for this - she was messing with accessibility options since she had some software keyboard coming up at login too

Still ironing out the kinks in a new install of Fedora 12.For some reason I am not able to change the icons, colours or font size used in the Nautilus file browser. While I am able to change these settings in System>Preferences>Appearance, changes just don't affect the Nautilus file browser, which continues to use the default Fedora icons in blue and 9 pt. Sans as its font no matter what I do. On the GNOME desktop I am able to adjust fonts and sizes, but when I change the icons, settings do not stick after a reboot.
I have tried deleting the ~/.gconf/apps/nautilus directory, downgrading nautilus, even removing and reinstalling it entirely, but to no avail. Tools like gnome-color-chooser affect the panel and desktop, but just don't have any effect on the Nautilus file browser. Why?This looks to me like a permissions issue possibly? The situation could be affected by the fact that the settings in /home were inherited from a previous installation of another linux distro.
I'm looking to set up a bit of a home server, and am wondering about storage. What I'd like is something like RAID 6, which has good redundancy built-in, but with this being a home server, I'd prefer to start a little smaller and leave room to build it up in future. I'd been looking at commercial products like the 'drobo', which seems fairly ideal, but I'd really like to see if I can do it myself. I understand that throwing the RAID into an LVM will allow for some expansion, but the last time I checked, most RAID setups called for the same sized disks, or at least limited the array by the size of the smallest disk present.
What I'd like is the ability to build a basic framework with a few cheap disks, and then as things start filling up, to be able to add larger ones (perhaps eventually pulling out smaller ones as though they'd failed and replacing them with big ones)
I have a Dell PowerEdge 840 that has no sound card. I would like to install a completely compatible sound card. I have not been able to find any recommendations for compatible sound cards on these forums, but I have learned that the C-Media chipset is supposed to be well-supported by Linux. There are C-Media sound cards on e-bay for under $10. I was considering a 6ch c-media 5.1 surround sound 3D PCI sound card. I believe the chipset is CM8738. Does anyone know whether this card is supported in F12? Or does anyone care to share any recommendations for sound cards that are known to be compatible with Fedora 12?
My intention is to be able to install a decent, inexpensive, commodity sound card that is known to be compatible with Fedora 12. I would prefer to purchase and install one that I know works rather than guessing and then fiddling with it forever and asking a lot of questions that could have been avoided.
Surprisingly, this information has been very hard for me to find. I understand that there is no Fedora hardware compatibility list, but it seems that a very brief list of hardware that is know to be compatible with the most recent release or two of Fedora could save a lot of time and resources. The purpose of such a brief list wouldn't necessarily be to see if a certain piece of hardware is compatible, but to find a component that is know to be compatible, so as to easily be able to get a completely functional system up and running.
I use a commercial finite element code to produce animated GIF files of my calculation results. In case you are interested, the code is COMSOL Multiphysics 4.0a, running on Fedora 13 x86_64. Note that the FEA code only has the option of saving movies as animated GIF files in Linux.
These GIF files tend to be quite large, and although they are adequate for my own use on my local computer system, I wish to convert these files into other standard formats of more manageable size. These smaller files would then be easier to distribute to others or to include in presentations and reports.
I would like to ask for recommendations for either GUI-based video player/conversion applications or command line codes that could, for example, convert from animated GIF files to MPEG files. I would prefer an application that allows for multiple input/output format choices as well as conversion options for changing the playback speed, splicing out a portion of the original animation, etc.
I am completely new to Linux in general, and have recently downloaded Fedora 15 KDE spin. I tried dual-booting between Windows 7 and Fedora by shrinking one of my Windows partitions (I have two, this partition not containing the Windows installation). I tried shrinking it to 30 GB less than the total space available on the partition, and after pressing continue, received an error (which I unfortunately dismissed quickly and can't remember). In the file manager, Fedora showed that my partition changed from 1.3Tb to 1.2 Tb, but I couldn't access it. Upon rebooting into Windows, I still can't access it, receiving a "format drive before use" popup and then error stating that it is possibly of a different filesystem or corrupt.
Unfortunately, I stupidly didn't backup any of my data (which I will be sure to remember to do in the future). I installed EASEUS Partition Master 8.0.1 Home Edition, which states that my drive is still of NTFS filesystem and has the total space it should. However, upon clicking "check drive," it states there are no errors and when trying to "explore files," it doesn't find any (yet it shows the correct amount of used and unused space). I then tried running TestDisk, but only allows me to check my media drive E, which is my dvd drive that has my Fedora Live CD in it (which cannot be ejected manually or through Windows, an error stating it cannot be ejected). I didn't go through with TestDisk for my DVD drive because I needed to verify the type of partition (which to my knowledge shouldn't even exist). It shows 700 something MiB / 600 something MiB. Although I have decent general knowledge about computers, I am a complete novice when it comes to doing something like this.
The "[SOLVED]" attribute to the How to set defaulter size in RHEL5 thread notwithstanding, the problem really is not solved. I've set my default language to both "C" and to "EN-us" and the problem is that absolutely every single time I print, I have to meander through varying layout print menus to find the "A4" setting and change it to "letter". That, or sacrifice the last two lines on every page because the default size is larger than the actual size. Bad default. It is not unique to Red Hat/CentOS, of course. Same problem exists on Debian and SuSE, too. Why is this such an intractable issue? Why is there not some simple and obvious way to say, "squish all instances of A4 (or "letter") and replace with "letter" (or "A4")!"?
View 5 Replies View RelatedWe talk about 12pt, 14pt font sizes. Do those numbers represent physical size in some unit or number of pixels? I guess it is the former, because same font size looks different for different DPI values, but in what unit? Also a relevant question: does browsers like firefox and chromium use different system of font sizes, because to get the same physical size, I alwasy need to set larger values in firefox than in other applications. Setting dpi and resolution values using about:config has no effect.

If you do a direct clone of a drive, you are supposed to make sure the target drive is the same size as the source drive.
It is quite important that I am able to clone a failing drive (250GB), however, my only other drive available is a completely new 1TB external hard drive from a different manufacturer.
Is it still possible for me to safely clone the failing drive? If yes, how would I go about doing this? Make a 250GB partition on the 1TB drive?
If I use the TB drive as a "temporary backup", and once I have copied over with dd burn everything directly to DVDs, and then restore the TB drive to it's original state, will this be able to be done?
I'm downloading the iso images for 9.10 Alternate CD. As the desktop does not work, graphical.

Windows is poppy-cosh, compared to the speed, performance, customization, updates, few errors and bugs, everything is superb!

Wine allows me to use all the programs I need that require windows, regardless.. You have converted me. "If you build it, they will come." Amazing job.
I tried re-installing windows and to no-evail for whatever reason screwed up my entire re-installation of Ubuntu. Instead of saying Owner it says Administrator for the new install. Here's my list:
1.) I need to completely wipe out all partitions and start over with a "fresh" HDD. Any ideas how to do so without an OS? It was suggested on wiki answers to use BootDisk.com
2.) I have the torrent downloading which is 689.6MB [URL] and the normal ISO which is 690MB [URL] from two different Ubuntu.com pages...Which do I use? Why are they two different file sizes? I assume the larger file size is the best to use. This has happened when downloading the Desktop CD as well. The lesser file never worked properly. Do you guys have incomplete files on the server or something or perhaps just my hardware?
3.) Use alternate installer to have Ubuntu as the ONLY OS. Alternate Option: Put Ubuntu alternate cd installer onto my external HDD by Seagate and boot up to it, then install ubuntu...
As a recent migrant to Ubuntu from Windows, I was expecting to be able to compare the sizes of two folders or set of folders by Bytes (as in windows). I'm slightly OCD when it comes to my personal files and folders, and I like to maintain identical backups in various pen-drives; as such, I was hoping to be able to track the file sizes of each folder set, but I can only do so in Kilobytes... Is there any application or other means by which to compare sizes in bytes --as is the case in windows?..
