How To Extend The / Partiotion In RedHat 5.4

Hi

RHEL 6.4 (64 Bit) is running as a Virutal Machine in a VCenter Server 5.5
As per our request, Vmware team added 500GB of disk space to this VM. Disk is not visible in "fdisk -l" after run the following command/script, but the new disk could be seen from the "multipath -l" command.

for i in `ls -ld /sys/class/scsi_host/host* | awk '{print $9}' `
do
echo "- - -" > $i/scan
done

Could someone clarify why it is not visible in "fdisk -l" output?

i want to know how to extend lvm partition

How can I make this Data partition be readable and writeable? I tried the "chmod 777" command, but was unsure of what directory to type in . I tried several but the command wouldn't start. This partition is on the second hardrive. I am just trying to get more storage on the second hard drive, so I hope I partitioned correctly. The drive was originally mounted as usr, but I managed to shrink that and make a new partition named Data.

I have followed all the instructions I have got from the net and made boot-able DVD's and USB sticks several different ways as people advise. I have done the same with Mint 17. I have created a partition (26G) and follow the install instructions 1: English 2:Has at least 7.4G available drive space. 4: Is connected to the internet. 5: Here it shows a page where I think it should display the drive options (but does not) If I push the "install now" button it comes up with an error "No root file system is defined --Please correct this from the partitioning menu" I close the installer and look at the drives in GParted and they are all there and the one I created for Linux is PARTITION - /dev/sda4 FILE SYSTEM - ext4
MOUNT POINT - /media/makulu/0C43086E0C43086E LABEL - Lin
SIZE - 26.02 GB USED - 590.07 Mb UNUSED - 24.44 GB FLAG - (blank)
No indication on how to fix the "No root file system" problem. I have tried so many bits of advise that I am beginning to think that I may be better of sticking to windows (perish the thought)
Can anyone help?

OK Im pretty new to Linux and learning so much, but with RHEL6,

When your taking a test and they say to make a partition this size/name it this, how do you know which disk to partition if you do a listing?

I get so confused with the fdisk stuff and I would really love it if someone is kind enough to help me out.

Code:

Disk /dev/sda (Sun disk label): 255 heads, 63 sectors, 60801 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Flag    Start       End    Blocks   Id  System
/dev/sda1             0     60795 488335837+  83  Linux native
/dev/sda2  u      60795     60801     48195   82  Linux swap
/dev/sda3             0     60801 488384032+   5  Whole disk

Actually i created 100 mb lvm partition using fdisk but after checking in fdisk, i am getting this. I don't know next time my system will boot or not.

What should i do in this situation to recover from this situation?

I am using centos6 x64.

Hello, I hope someone can assist. I have installed 17 on 2 laptops and 17.1 on another all with windows 8 upgraded to 8.1 Now I have a new PC with 8.1 and cannot get 17.1 to install. I go thru all the steps but when I get past "something else" and choose the "free space" that I partitioned in windows and hit install the window pops up with "no root file system is defined" "Please correct from partitioning menu.. I have never had this happen, did I not do something? There is 1 300mb(fat32, efi) partition, ntfa, free space(which is where I am trying to install Linux), 1 small and 1 large "free space". Then the define for boot loader installation, which I do not remember needing to do before. Can someone please help. The PC is an Acer Aspire, amd10, 3.7ghz, quad core, radeon hd 8670 graphics , 1 terabyte hdd, 4gb ram, windows 8.1

Hi everybody,

I am trying to set up my sd card with an embedded ubuntu I build lately according to this linkhttps://eewiki.net/display/linuxonar...-Ubuntu14.04.1 (Topic Setup microSD/SD card).
I am doing this on Ubuntu running in VirtualBox. I am quite new to linux and barely understand the command that causes the first warning. Here is what happened:

ubuntu@ubuntu-VirtualBox:~$ sudo sfdisk --in-order --Linux --unit M ${DISK} <<-__EOF__ --force
> 1,12,0xE,*
> ,,,-
> __EOF__
Checking that no-one is using this disk right now ...
BLKRRPART: Invalid argument
OK

Disk /dev/sdc1: 1019 cylinders, 246 heads, 62 sectors/track

sfdisk: ERROR: sector 0 does not have an msdos signature
/dev/sdc1: unrecognized partition table type
Old situation:
No partitions found
New situation:
Units = mebibytes of 1048576 bytes, blocks of 1024 bytes, counting from 0

Device Boot Start End MiB #blocks Id System
/dev/sdc1p1 * 1 12 12 12288 e W95 FAT16 (LBA)
/dev/sdc1p2 13 7591 7579 7760896 83 Linux
/dev/sdc1p3 0 - 0 0 0 Empty
/dev/sdc1p4 0 - 0 0 0 Empty
Successfully wrote the new partition table

Re-reading the partition table ...
BLKRRPART: Invalid argument

If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes: dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk(8).)
ubuntu@ubuntu-VirtualBox:~$ sudo mkfs.vfat -F 16 ${DISK}p1 -n BOOT
mkfs.fat 3.0.26 (2014-03-07)
/dev/sdc1p1: No such file or directory


So after I entered "sudo sfdisk --in-order --Linux --unit M ${DISK} <<-__EOF__ --force
> 1,12,0xE,*
> ,,,-
> __EOF__ "
everything looked fine since it sad that it created the partition sdc1p1 etc. but as soon as I want to format this partition with "sudo mkfs.vfat -F 16 ${DISK}p1 -n BOOT" it tells me that there is no partition called /dev/sdc1p1

I would be very gratefull if somebody could help me out on this. I thought about trying a different tutorial but they look really really different so I tried to stick to the one that worked well for me so far.

Thank you very much!

Lenni

I've made a couple attempts at installing these OS's on my machine and am still not getting it. I've actually been using AVLinux for about the past nine months, and it's working fairly well. And, yes, I know XP is down for the count, but for the moment it's the only MS option available to me - and I *need* to get it running for some work related web stuff...

This is all on a 32 bit AMD system btw.

What I've tried: Everything on one SATA drive. Partition one formatted to NTFS (about 20GB) for XP. Partitions 2 and 3 are Root and Home for AVLinux, Partition 4 at the end of the drive as the /swap for AVL.

All the how-to's and guides I've been able to come across point to (usually) Mint or Ubuntu's install dialog, and to select "something else" - which, by the way, is not a function of AVLinux's installation procedure. During install you can install GRUB to the MBR *or* root partition..

So, just to clarify to procedure (as I might have it now, but am very unsure) XP gets installed first (which is done at this point...) then my Linux distro *to the MBR* (?) then I need to add a stanza to GRUB telling it where XP lives? XP is not showing up on GRUB as I'm doing it, but I'm not too sure if installing Linux to the MBR (on the same physical drive as XP) actually wipes out the Windows bootloader....and if so, how chainloading would actually work...

So, any help appreciated, thanks.

Hi All;
Can someone give me some guidance on partitioning a 4TB drive into one partition ?

My goal is to align the partition for best performance. I searched the net for advice and I've found a lot of information on it but am still confused.

After setting the label to gpt,

I tried mkpart primary 0% 100%
and I get the warning that the partition isn't aligned

then I tried mkpart primary 1 -1 (which I really hoped would get me completed)

and when I do an align-check on partition 1, it reports 1 aligned

but then when I do an fdisk -l,
I get the warning that partition 1 does not start on a physical sector boundary

I read that sector size is usually 512 bytes but on some (or perhaps all) larger disks, the sector size is 4096.

I am really not knowledgable in this area and not sure if the above message about partition 1 not starting on a physical sector boundary is important or what impact this will have to my performance. Since these 4tb drives are being used in a media server, I'd like them to be as fast and efficient as possible.

Can you offer some guidance or perhaps some commands on how to partition my (full) 4tb drive into one partition so it is aligned and also so the partition table starts on a physical sector boundary ?

Also, is there a Ubuntu utility to display the sector size of a disk?

I have been researching this issue off and on for a few weeks and would like to finally get this partitioning completed this weekend so I can get on with setting up my system.

Thanks.

Tim
