I currently have an array with 8TB, that will eventually grow to 10TB+ with 2TB disks. How would I partition, format, then mount an array of this size, and also have room to grow, when I add new disks? I heard ext3 only supports 8tb? So would lvm be the best use here?

I have a server with 3 hard drives
1 400GB
2 1TB
The 400GB has the OS and SWAP while the 1TB are going to be used as storage....
Now for the problem, when I have both the 1TB drives in I can not format or mount either 1TB drives. Says Device is in use or "The device file '/dev/sdc1' does not exist"
Now if I take one of the 1TB drives out I can format, partition, and mount it no problem...it only seems to be a problem when both drives are connected...

I created two software RAID1 arrays with the following commands:
mdadm --create /dev/md2 --level=1 --raid-devices=2 -v /dev/hda5 /dev/hdc5
mdadm --create /dev/md3 --level=1 --raid-devices=2 -v /dev/hda6 /dev/hdc6
and I verify that /dev/md2 and /dev/md3 exist. But if I reboot the computer, these two devices are gone. I'm sure I am overlooking a step but I can't seem to find what it is. Could someone tell me what I need to do next?

i want to remove the raid 1 arrays on our server centos and use standalone drive
View 3 Replies View RelatedWe have CentOS on an HP proliant g5 server and attached to it is an DAS with 3 branches of disks so 5 - 5 - 5 drives.Now what we had so far there is that every branch was on raid 5 and totaling 3 mounted drives each with 4TB (disks are 1Tb each).But a couple days ago something happened while i was replacing older drives with some bad sectors with new one. What I did is to remove old drive, put in new one, initialize and attach to array and rebuild starts.Now somehow 2 drievs ( as i was rebuilding 2 arrays at once) switched place.so disk on 1_1_5 and disk on 1_3_5 switched place. There coul dbe possibility that I made mistake and assigned them to different arrays when initializing but that is really hardly as i replaced one then later another so...
Anyway to the to the point.Is there painless option to remove 1 disk from array and then assign it to other array and then let raid rebuild everything normally?I;ve made backup of everything there so there is no fear of loosing anything...By the way at the same time when that switch happens a partition from 1 raid array completely dis speared and there is only unallocated space on that one right now.
With mdadm was only able to add a new drive to the using the --force function. I do not feel comfortable with using the function that way though.
When I remove a disk in VMWare, it perfectly says that the drive is lost and the array is degraded (mdadm --detail /dev/md0). Although after re-adding the drive, it immediately shows device as busy for both mdadm and sfdisk when I don't use --force.
Recovery and repairation of degraded array worked fine with sfdisk --force, mdadm --add --force, it automatically started recovering and took not so long.
What are best practises to manage software raid-1 arrays?
I had a drive with a partition layout like so:
~50gig Windows 7 - NTFS
~100gig Ubuntu - EXT3
~100gig Snow Leopard - HFS+
~100gig Extended Partition
-- ~100gig Swap Disk - exFat
I wanted to delete the Snow Leopard partition and format the Swap Disk partition to something else. exFat was causing major file size bloat on small files. QT sdk bloated to like 11 gigs or something ridiculous like that. Anyways, I loaded up an Ubuntu 10.04 LTS live cd and gparted then deleted the Snow Leopard partition. Gparted said "Mission Accomplished" and tried to rescan the drive, but never found it. At this point I restarted the computer, a dell laptop, which didn't boot with an unable to find a bootable device error. The ubuntu live cd doesn't see the drive anymore. gparted scans for drives indefinitely and fdisk -l has no output.
i have instaled ubuntu 11.04 wubi on my pc with windows 7. i installed and everything was going ok i navigate on ubuntu already. but the problems star here i went on my ubuntu to the partition section and i format my windows partion to be the home partion and changed the nfts to ext, i did the upgrades but i forgot that theyr running yet and i restart my computer when it boot again it gaves me an error:
try (0,0) : nfts5 : wubildr
try (0,1) : ext2 :
and the windows7 says that i have to instal again. so i went to another pc and i made a cd boot and a pen boot. i burned the iso (downloaded from the ubuntu oficial site the 11.04 32 bit version) image to the cd and pen drive prperly, i adjust my boot options to star from usb or cd rom and nothing im struck.
So I tried adding a new, 2nd hard drive to my Ubuntu 9.04 desktop for some additional storage and only managed to kill my system so that it won't boot up anymore (I just get a blinking cursor after the BIOS does its thing).I could sure use a little help getting back to a functioning system, and then adding the second drive. I tried following the instructions from this link to add the 2nd drive:

I need to change my LUKS partition to NTFS as I do not need the boot partition any longer, but I need to keep sdb3 (truecrypted ext3) intact. This is how the disk looks now:

I currently run a dual boot with Windows Vista and Ubuntu Lucid. I have been using Ubuntu for quite a while now, but kept around Windows "just in case." I have decided that keeping Windows is unnecessary and my Ubuntu partition is running out of space. I was wondering how I could format the Windows partition and add that space to the Ubuntu partition without having to format my entire computer.

I have USB which is already not recognised windows and when I insert while ubuntu is on. It does recognise it. But does not allow me to mount, no matter through command line, or won't let me format it through disk utility.

I have openSUSE 11.2 installed on my PC, the install went well and was quite pleased with the OS. Howeve, because I only had a small 40Gb hard-drive I decided to buy a new Western Digital Green 1Tb SATA drive for storing my music etc.Now this is where I have run into difficulty. I can't get the OS to see the new drive, I did a search and found some instructions on how to format, mount, setup the 2nd drive but I either missed something or I just didn't do it correctly.In the end I could see the drive under Nautilus and that was it.
I can't write to it because it says I don't have permission? I can't seem to make new directories, most likely because I don't have permission. If needs be I will be willing to go back to the beginning and start installing the drive again. I don't mean to beliitle the Linux OS and users but using Windows$ all my life (I'm 49) I find it a lot easier, but I am willing to learn this new OS (for me that is).

I've just bought a HP mini compaq laptop. The laptop doesn't have any CD/DVD "reader". So i was forced to download the .iso file to install ubuntu in addition to Windows XP that was present when i bought it. To do so i used UNetbootin, and i used my only hard disk as a live CD. But when i wanted to install ubuntu, they told me to create a partition. The problem is that i can't. I have only one partition sda1(nfst) which covers the whole stockage memory, and an empty space(8Mo). I can't acceed to any of the resizing or modifying options to edit the nfst partition. The only options are manage flags and umount. When i click on this one, they tell me : # umount /cdrom : cdrom is busy.
View 3 Replies View RelatedI'm trying to install a dual booting machine with OpenSUSE v11.1 32bit and CentOS v5.2 64bit. I installed OpenSUSE first and allowed it to install and configure grub in the MBR and after that I wanted to proceed with CentOS v5.2. The installation went fine with two notable exceptions:- when I had to configure grub installation parameters, CentOS offered me only 2 solutions: either install it on the MBR of the first hard disk or not installing it at all. Other distributions are more flexible allowing you to install it in the boot sector of the root partition for example. Because I didn't want to ruin the existent grub onfiguration, I reluctantly accepted not to install it for CentOS assuming that I could manually configure the entry later in grub's menu.lst file.
- when I was presented with the options for software components installation, I've clicked on virtualization category/function because I intend to use the machine as a VMware host. There was no guidance on screen at that point and I blindly assumed that by choosing the virtualization function I would get necessary tools and drivers that will help me further on. It seems that this was a wrong move as you can see it below.
After completing the installation, I tried to search for a template or guiding on how the menu entry in menu.lst should look like but the grub directory was empty, not surprisingly because I've told CentOS earlier not to install it. Using the files in the /boot directory from the CentOS installation I tried to improvise a menu entry but it's not working. The boot stops with famous Error 13: Invalid or unsupported executable format. Using the file command to check what kind of files I'm trying to load as kernels I'm getting :

Santa brought me an early Christmas present: a new External HD - Verbatim CLÖN - 250GBPlug it in and it works great. Problem is this: I do not use Windows at all just Debian Squeeze and this thing is formatted FAT32 - an ancient format.I would prefer EXT3 or maybe NTFS to be compatible with Windows "IF" there is a need (cousins etc).However as soon as I format it to NTFS or Ext3 it becomes "root" only.This is my HD, how can I format it and keep permissions for myself?
A friend suggested changing /etc/fuse.conf
# Set the maximum number of FUSE mounts allowed to non-root users.
# The default is 1000.

I have a SAN drive space connected to a SLES 10 (OES2) server. The server sees the drive at /dev/sdb1, and I was able to use fdisk to create a partition on it. I created a new directory /mnt/testvol, where I would like to mount the SAN drive to.
Fdisk shows the volume to be at /dev/sdb1 and lists it as Linux filesystem.
I used this command to try to mount it:
mount /dev/sdb1 /mnt/testvol -t nfs
and I get this error:
mount: directory to mount not in host:dir format
I've installed Ubuntu Server, and Webmin following this guide, and all is well so far... I've mounted some drives with some pre-existing data on them, and can view the data on those drives. But I have one drive that I can't seem to mount, and I'm pretty sure there's data on it. But I can't seem to find how to identify what format the data is in, ie.. ntfs, ext2, ext 3, etc. Its likely pretty simple, but how can you identify the drive format before you attempt to mount it?
