I have installed Ubuntu 10.04 LTS on machine but wanted to choose RAID and LVM during partition scheme. Unfortunately I couldn't find such option during partitioning. Is it true that for Ubuntu 10.04 LTS it is unable to use RAID and LVM ?
View 2 RepliesI am not really sure if the title makes any sense or if it even possible. Basically I am currently triple booting with Mac osx on the first partition windows 7 on the second and ubuntu linux on the 3rd with a swap partition. So basically on my 2TB harddrive
Mac (200gb)
Windows (200gb)
Linux (200gb)
Swap (8gb)
NTFS(1592gb)
The last partition is formatted as ntfs using Gparted, windows cannot detect it. The windows disk partitioner shows the swap and ntfs partitions as unformatted. I can unformat the space and use the windows partition to add format it as ntfs but it would format the linux swap partition as well. I am worried that it could potentially screw up everything on my harddrive. My question is. What do I need to do to get the ntfs parition recognized by windows (should I use the windows partitioner)?
Just wondering if Ubuntu will install alongside OSX on a GUID partiton scheme.
View 1 Replies View RelatedI setup a dual boot system, with approximately 200gig planned for ubuntu 10.10. Based on the article here:[URL]..And this quote:
Quote:
# sda1 Recovery Partition, unchanged
# sda2 Windows partition, shrunk preferably from inside Windows, hopefully about 30Gb
# sda3 Primary Partition, 10Gb, file-system = ext3, in the Partitioning Section of the installer change the "Mount Point" = /
[Code]...
I assumed at that point that the "sda3" "/" would be for booting purposes. I would have to guess that I was wrong, because it is filling up very quickly. As you may be able to tell by the screen shot, "sda5", "/home" was what was assumed to be the file structure to store all of the programs and such.
I have only been running this setup for a week, and would expect to not be seeing my "boot" partition growing so quickly. Do I need to resize it? here do the standard programs that I get from the ubuntu software center install at (partition wise)? I suppose I dont mind wiping that section dry and starting over, but I would give a resize a try if possible.
I am a total noob for Linux / Ubuntu. I have been using windows all my life and I decided to get rid of Bill finally. I want to install Ubuntu by Manually partitioning my HD. I have a 500GB HDD. optimal partition scheme. I repeat i am a total Noob. please let me know details for each partition like
1. Primary or Logical
2. type
3. mount point
4. size
I am having no other OS in the pc. just planning to have ubuntu. no dual boot needed.
I'm installing Centos 5.5 on a HP ProLiant DL180 Server with ~8 TB of hard disk (4 disks that have been pre-RAIDED), from an installation DVD.
Normally when I get to the partitions screen, I would select "remove all partitions etc".
But this gives me an error message "Your boot partition is on a disk using the GPT partition scheme but this machine cannot boot using GPT. This can happen if there is not enough space on your drives for the installation."
Pressed OK, tried the other three partition options but they led to the same outcome.
Tried Advanced storage configuration: Showed that there was one hard drive (c0d0) with ~ 8 TB of space.
I figured I should create a root sector, set one up with 100 MB of space, ext3, set the mount point as /.
Created a software raid of the remaining space.
Trying to go "next" gave me a similar error about GPT partition scheme. Trying various other configurations all gave similar errors about the GPT scheme.
What do I need to do? Some earlier hard format of the disk or something?
i was experiencing slow start ups since i installed ubuntu 11.04. it took about 20-30sec for the apple logo to come up (or rEFIt). today apple released EFI firmware updates which doesn't seem to install. reason is that the partition scheme is not compatible. EFI Firmware updates only install from GUID partition schemes.
DiskUtility tells me i have MBR. So it seems like Ubuntu changed the Partition Scheme.
Can any body confirm that? how can i make sure ubuntu installs into existing GUID? i will re-partition later today and give you an update if the EFI firmware update installs and boot time is faster.
A snapshot of my existing partion configuration can be viewed at: [URL] I intend for the space including /dev/sda1,dev/sda2 and /dev/sda3 to be used by slack 13.0. The OS at /dev/sda6 and /dev/sda7 will be "retired" once I get slack up, running and configuration for my work. In the past I have preformatted partitions, that is, from the existing OS, I have formatted partitions for use by the next OS, using gparted. In the case of ubuntu, that has worked well. And frankly, I'm pretty rusty with fdisk....
1)Is there any advantage - or disadvantage - in my doing this for my pending slackware installation? Will slack recognize the "clean" partition and opt to skip formatting?
2)I presume that slack will recognize the existing swap partition. Am I correct?
3)My scheme would be to provide separate partions for /, /home/ and /usr or /usr/local.
4)Any recommendations on filesystems?
I thought this might interest someone out there:[URL].. I used SD cards with MBR formatted as ext2 for backup. After I read these articles, I reformatted my cards with GUID Partition Table and ext4 format. Now I make my backup in half the time!

As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.
I have two hard drives inside an Ubuntu 9.10 machine, each with a data partition on. What I want to do is as I save files to one data partition partition (or delete them) I want the files copying/deleted automatically on the the other data partition. I do not want to start using RAID or end-of-day incremental backups.
View 5 Replies View RelatedHow do I recreate an LVM raid 1 partition, without destroying data on the discs? I have a 650GB data partition which is a raid 1 array with ext3. Two days ago, the system (Ubuntu 9.04) started to refuse to write to it, claiming no space left on device - even if there is ca. 102GB free left, if the disk is 85% full (according to df)! Interestingly, removing a couple of GB did not help, after reboot the disk was again full..
I did the "tune2fs -m 0" trick and then forced file check on next reboot by "sudo touch /forcefsck" .. and the result is that the raid partition is gone. I have the two physical drives /dev/sd*, unmounted, but the /dev/md1 is no longer there. What can I do to re-create it, without losing the data? I realized that I ran tune2fs on the physical partitions /dev/sd* - was I supposed to run it on /dev/md1?
To be honest, I am trying to install Linux Mint, but since this is based on Ubuntu, and I am comfortable with Ubuntu on my VM I decided to label it Ubuntu.
I have a 235 HDD and it is partitioned like this:
C: 150 GB (Windows) NTFS
D: 70 GB (Data) NTFS
G: 15 GB (for my not yet installed Linux) NTFS
I also followed this tutorial and now I have some sort of LiveCD inside my USB: [URL]. So, now I have a pen drive with an Ubuntu LiveCD and a 15GB ready for my Ubuntu!
This is what I do:
1 - connect pen to computer
2 - turn on computer
3 - pen start running and I load Linux like a LiveCD (yey!)
4 - Linux loads and I wait
5 - I click "Install linux"
6 - I configure the language, time zone and keyboard with no problems
7 - Disk partitioning ... it offers me 2 choices:
7.1 - Erase entire disk and install Ubuntu
7.2 - Manually partitioning: but drive C:, D: and G: do not appear!!!
I want to install my Linux on driver G:, but I don't find a "Install Linux in this specific partition" option!
Is it possible to use the 'discard' option when mounting an ntfs-partition? Because I'm buying an ssd and I intend to dual-boot windows xp (which doesn't support TRIM) and Ubuntu 10.10 (which does).

View 3 Replies View RelatedI am unable to hibernate my computer while using Ubuntu and I figured out the reason--Ubuntu is not using my swap partition. I would follow the existing tutorials on setting up a swap partition after installing Ubuntu, but since the volume uses hardware RAID 0, the swap partition is not assigned a /dev/ entry (like /dev/sdxx) and I am not sure how I can mount it.
Here is what I have:
Code:
I am trying to grow my array to make full use of my drives. I have a raid 6 using mdadm on my home server. The array used to consist of 6 1.5TB drives when it was created. Since then I've been replacing the 1.5TB drives with new 2TB drives. And now I have replaced the last 2 drives.
When I added the first 3 disks I did not use the whole disk for the raid partition but rather made it the same size as the 1.5 partitions. As it turns out this may have been a bad idea. (But it gave me another 3 partitions of 500GB that I turned into 1 disk using mhddfs.)
Now I'm trying to grow the array. I've been testing in a virtual enviroment on how to do it but I cannot find another method than this :
1) fail 1 disk.
2) re-partition the disk with the size of the whole disk.
3) re-add the drive as a spare.
4) start the now degraded array to let it resync.
5) wait quite a while. (aprox 5 hours)
6) start again from step 1 for the other disks.
7) use mdadm with grow command to enlarge the array
use resize2fs to fill array to max size
Now although since this is a raid 6, I keep some redundancy but I still worry about degrading the array so manny times and rebuilding the whole thing. I mean I read the thing out 3 or 4 times over doing this.

EFI GUID Partition support works on both 32bit and 64bit platforms. You must include GPT support in kernel in order to use GPT. If you don't include GPT support in Linux kernel, after rebooting the server, the file system will no longer be mountable or the GPT table will get corrupted. By default Redhat Enterprise Linux / CentOS comes with GPT kernel support. However, *******if you are using Debian or Ubuntu Linux,******** you need to recompile the kernel. Set CONFIG_EFI_PARTITION to y to compile this feature.
Is this true? Ubuntu has no GPT support native to the server install? Never compiled a kernel. Is that of itself going to be a mind bender? How much doo doo am I going to get into if I haven't done it a few times? Trust me when I tell you its no thrill formatting and reformatting a 8tb raid drive or the individual disks if it screws up. Been on that ride way too long already. Need things to go smoothly. This is not a play toy server, but will be used in a business.

I have been working in my spare time over the last few days, Had problems with the whole grub2 not installing on RAID 1. Then I found out that I had to have a separate non raid Ext4 partition on one drive with "/Boot" as mount point and install went though fine.
My question is, will the developers FIX this. I mean if I only have 2 x 2tb drives in teh pc as RAID 1, and the one fails with the boot partition the whole machine goes down. Kinda defeats the whole RAID feature huh.
I USED to run a windows network with RAID 5 servers, and windows never had a problem installing everything on the RAID. Or even setting up RAID 1 in the bios on the PC and installing XP or NT4 on the RAID 1. There was never a need for a separate non raid boot partition.
Do we need a separate RAID friendly/enabled Grub? I guess for now I will get a 250gb drive and install the Server OS to it, and setup RAID1 manually after the server OS boots. Then will make a ghost type image of the server in case that drive fails so I can quickly install a new drive and restore the image and get it back up and running again.

Another small issue is the cipher I used. I don't remember which kind of encryption the disk is encrypted with (80% sure it's aes though).
