Ubuntu :: RAID Via Disk Utility?

Jul 20, 2011

Has anybody ever used Disk Utility to set up software RAID? Here I am running terminal commands (I'm a terminal junkie) and I just happen to stumble across instructions that indicate "Or you can just set it up through Disk Utility."

Sure enough in disk utility, it looks like all of the configurable options are there. It makes me wonder, though... is this kind of GUI functionality something that isn't really solid? Or does it operate predictably and effectively?

Ubuntu Servers :: Start The RAID Using "Disk Utility?

May 5, 2011

My system locked up while copying files last night. My RAID array will not start. I did verify my UUID's. (Lesson learned.) I do not understand a few things.1. Why do different drives show "active sync" on different drives? 2. Why does "Disk Utility" tell me the RAID is not running and when I try to assemble the RAID, mdadm returns: mdadm: device /dev/md0 already active - cannot assemble itWhen I try to start the RAID using "Disk Utility":

Code:
Error assembling array: mdadm exited with exit code 1: mdadm: cannot open device /dev/sdd1: Device or resource busy
mdadm: /dev/sdd1 has no superblock - assembly aborted
So, I examine sdd1:
Code:
sudo mdadm -E /dev/sdd1

Ubuntu Servers :: Creation Of RAID-0 Array In Disk Utility Resulting In Smaller Than Expected Array?

Sep 27, 2010

I have a NETGEAR ReadyNAS NV+ with four 1TB drives in a RAID-5 array. This is our primary file storage. This has previously been backed up to a hardware RAID-0 array directly attached to our Windows server. The capacity of this backup array is no longer sufficient. So the plan was, take a bunch of 200GB to 320GB drives (And a 750) I had kicking around, chuck them in a couple of old SCSI drive enclosures I have collecting dust, attach them via IDA/SATA-to-USB adaptors to a USB hub, attach that to the server, create a JBOD array spanning the disks, and back up the NAS to that. Performance is not an issue as this is just to be used for backup, with the idea being as near to zero cost as possible (Spend so far = NZ$100�ish).

The first hurdle I struck was Windows not supporting Dynamic Disks on USB drives (Required to create a spanned volume). At first I resisted using another machine (i.e. a machine running Ubuntu) as I didn't want to dedicate a piece of hardware to backing up the NAS. I then decided it would be acceptable to do this via a VM, which is what I've done.So I have 10.04 running under VMWare Server 2.0.2 under Windows Server 2008 R2. The disks are all presented to the VM. I wasn't sure if I was going to end up creating the array under LVM or something else, but I noticed Disk Utility has an option to create an array, so I tried that. When I add two 250GB drives, the array size is 500GB. When I then add a 160GB drive, the array size drops to 480GB. Huh? If I keep adding disks (Regardless of order) the final array size comes out at 1.8 TB, as per the attached screenshot. Now with the following drives, I expected something more like:

160 + 250 + 250+ 750 + 250 +200 + 200 + 250 + 320 + 250 + 320 = 3.2TB

Am I missing something or making a false assumption somewhere?

General :: Windows 7 Disk Management Utility Doesn't Show Disk With Ext3 Partition

Oct 10, 2010

I have a 2 TB disk in an external SATA dock, formatted with a single ext3 (Linux) partition, which doesn't show up in the Windows 7 Computer Management->Disk Management utility, even as a raw/blank disk. I've verified that there's nothing wrong with the disk by connecting it to my Linux machine and mounting it, and I've verified that the dock is functioning properly by connecting a different FAT32-formatted disk, which mounts flawlessly as expected.I realize that I can't actually read the ext3 partition without additional software (e.g., Ext3IFS), but why doesn't the disk show up at all? Is there some sort of stupid anti-Linux filter built in? Is there any way to force Windows to recognize the disk, so that I can at the very least use direct block access with it?

Background: I want to clone an identical 2 TB disk onto this one. Due to my hardware layout, it's much easier to have the source disk attached to one machine and the destination disk connected to another, and do the clone over the network (the network is not a bottleneck with switched gigabit ethernet), than it is to hook them both up to one machine.(1) I did this once before when both machines were running Linux, but I've since upgraded the destination machine and decided to switch back to Windows for regular desktop use. I've got Cygwin installed, and have verified that the same basic method (dd + nc) will work, but I can't do anything if Windows doesn't even consider the destination disk to exist.I only have one eSATA port on each machine. Opening them up just to do this clone is a rather large annoyance. Also, since this is my backup disk, I'd like to eventually automate the cloning from the active disk to another one that I regularly swap with a third disk that I store off-site.

General :: Disk Utility And Df Show Different Disk Space ?

Nov 18, 2010

I don't understand disk sizes in Linux. I have a 500GB drive. It's ext4. I have run "tune2fs -m 0" on it to reserve the amount of space reserved for root to 0.

I'm using Ubuntu 10.04 that comes with a Disk Utility. When I run "System->Administration->Disk Utility (palimpsest)" the disk shows up as 500GB (see picture). But when I run df -h it shows up as 459GB. So, I don't understand the discrepancy.

When I run df I get the following:

Question: Why is Disk Utility showing me something different than "df"?

Hardware :: Best RAID Monitoring Utility?

Jan 18, 2010

I am looking for recommendations on monitoring RAID array status in a "hardware RAID" setup (ie, using a RAID controller card or RAID-enabled motherboard).Here are some clarifying points:

1. OS is CentOS 5.
2. No drive lights are visible on the exterior of the system. So periodically checking for amber lights (indicating drive failure) is not an option.
3. No SNMP manager/collector is available. This question refers to local-system options. Not network-based options.

Ubuntu :: LVM With Palimpsest Disk Utility

Apr 3, 2010

I'm working on setting up a new NAS. I installed Karmic desktop on a 160 GB HD using the default settings.

Now I've added three 1TB drives and want to make them a RAID-5 array with LVM on that, and 1 ext4 partition. I want to use LVM so I can add drives and expand the array later.

So far I've been using Disk Utility (Palimpsest Disk Utility) and it's been great! A wonderful addition to Karmic! I got the RAID-5 array setup with no problems using disk utility. So now I have a 2000 GB raid-5 array setup in Disk Utility and I need to get LVM setup.

Problem is: I don't see any sign of LVM in Disk Utility. I've been googling all night and I can't find any documentation for setting up LVM in Disk Utility, just people saying that it's supported.

I tried installing the lvm2 package, rebooting, and then looking around again. No luck.

So, what am I missing? Should there be LVM options in Disk Utility? Where is it? Is there a better/easier way to configure lvm?

Ubuntu Servers :: HW RAID Disk Shows Up In Fstab But Not In /dev/disk/by-uuid?

Jun 28, 2010

I have an SiI hardware SATA RAID card, with two 500GB disks in mirrored RAID configuration. When I first plugged them in and set it up, things seemed to work ok, but on boot the raid controller told me that the RAID needed rebuilding, and it would happen automatically after POST. So I didn't worry about it, and the drive mounted fine, and it's been that way for years. I just went in and manually on-line rebuilt the RAID in the controller's BIOS, and now when I boot into Ubuntu, both disks show up in fdisk, but neither show up in /dev/disk/by-uuid. Am I missing something?

Fedora Hardware :: Motherboard Configuration - Raid Setup Utility Shows Drives Out Of Order

Sep 19, 2010

I just went out and bought stuff to build a new computer, and among the parts was a Gigabyte ga-890fxa-ud5 motherboard ([URL]). The board has 3 (well, 4, but we'll stick to the 3) main sata interfaces, with 2 slots per interface, allowing 6 sata drives. In slot_0 i put my blu-ray drive, in slot_1 i put my drive that will host the OS and its partitions, and that is in the sata connector pair on the left. The middle sata connector pair (slot_2 and slot_3) i have 2 2tb drives, and in the sata connector pair on the right (slot_4 and slot_5) i have 2 1.5tb drives.

Ubuntu Installation :: Migrate Working Single Disk System To Existing RAID Array Using Disk UUIDs

Aug 1, 2010

I had done a new lucid install to a 1 TB RAID 1 array using the alternate CD a few weeks back. I messed up that system trying to some hardware working that lucid doesn't have drivers for yet, so I gave up on it and reinstalled to a single 80 GB disk that I now want to move over to the RAID array.

I moved all of the existing files on the array to a single folder, then copied all of the folders from the 80 GB disk over to the array with permissions and symlinks (minus the contents of /proc and /sys, which I created empty).

These are the commands I used:

Quote:

p -a -d -R -v -t /media/raid_array /b*
cp -a -d -R -v -t /media/raid_array /d*
cp -a -d -R -v -t /media/raid_array /e*
cp -a -d -R -v -t /media/raid_array /h*

[Code]....

I tried to change fstab to use the 689a... for root, but when I try to boot, it's still trying to open /dev/disk/by-uuid/412d...

So then I booted from the single disk again and chrooted into the array, then ran update-initramfs -u. I got 3 "grep: /proc/modules: No such file or directory" errors, and "cat: /proc/cmdline: No such file or directory"- so I created directory /proc/modules, created an empty file /proc/cmdline, and ran the initramfs update again. Then I tried to shut down, which hung (probably because I was doing all of this from a terminal window in Gnome), so I killed the power after a couple of minutes.

It's still trying to use /dev/disk/by-uuid/412d... to boot.

What am I missing? I assume I just have to change the UUID to mount as root, but I don't know how.

Ubuntu :: Disk Utility - Expand Array

Aug 31, 2010

When I use disk utility to expand my RAID array it creates a partition on my 1.5TB drive which it would like to add to the RAID 5.

However, none of the drive existing on the RAID are partitioned so what I think has happened is the partition itself has created a difference of about 2 million bytes smaller than the others and thus unable to add the component.

How can I specify the exact bytes for my hard drive partition so that I can add this to the array?

Ubuntu :: 10.04 64 Bits: Mounting With Disk Utility

May 15, 2010

I have an annoying problem with the Gnome disk utility. Whenever I want to mount a file system it is mounted as a removable disk in /media. For instance if I want to mount a raid array /dev/md0 to a mountpoint /music it is mounted as /media/music. That's not how I want it, I want it to be mounted to the desired mountpoint which is located directly on the root.

Hardware :: Fedora 11 RAID 1 - Disk Failure - Boot From The Single Working Disk?

Oct 16, 2009

my Fedora 11 system is not starting anylonger. It stops with the message:

Code:

VFS: Can't find ext4 filesystem on dev dm-0

The system told me since a while, that a lot of the sectors of one disk of the (software) RAID compound are failed already. So tried to disconnect each of the disks and start them separately. Unfortunaltly this is not working (for one its is not working at all, the other wents the same far as with both), when I tried to recover the system with the Fedora DVD, it said no distribution found. I am quite new and do not know so much about linux system, so i do not know what further information you could need. Maybe it can be important, that both disks are encryped (the system wents so far, that I can type in the password).

Ubuntu Installation :: Disk Utility Doesn't Work?

Jun 28, 2010

I found it is impossible to format partition during Ubuntu 10.04 installation.
My storage configuration is as following. 1TB (500GB X 2) AHCI RAID 0 (it is said fake raid) and covers below 4 partitions.

/dev/mapper/pdc_dgbbagea1 9621688 5872752 3260168 65% /
/dev/mapper/pdc_dgbbagea4 945587172 95673304 802259056 11% /home
/dev/mapper/pdc_dgbbagea3 9698380 1363364 7846240 15% /opt
Partition 2 is swap partition and root partition is ext3 original.

Since there is no enough space for upgrading, I try to format root partition and install a complete pure new OS. After I booting up system from Live or Alternative disk, I try to switch root partition from file system ext3 to ext4 and format it. However, Formating process always get failed after couple trying. Even I quit installation and use tools "Disk Utility" to check and adjust partition information. It reports device is busy.

I have a HDD with OS Win with three partitions NTFS.I installed Ubuntu 10.10 on new partition, and I left the old partitions on the disk, because there are a lot of my personal data.When I was looking for how to mount partitions on startup, I was fortuitously to Palimpsest Disk Utility selecting the checkbox on sda2 as a boot, and apply. But I saw that it was wrong and took the check back. And after this was damaged NTFS on the partition sda2. Windows shows the partition as RAW.

General :: Used The Disk Utility To Edit The Partitions ?

Jan 11, 2011

I was on Ubuntu 10.04 I used the Disk Utility to edit the partitions.

Here is the table it's showing:

Here I deleted 79 GB patition from FAT32 to NTFS and deleted 50 GB space that was ext4 partition where SUSE was residing the bootloader was of SUSE that was working using the same utility.

After that with a live cd of ubuntu I tried to recover the grub but there was no device.map file. Later I found the partition table absent.

The utility shows above table but Gparted shows only 500GB free space without any partition. Please help can't loose all the data.

I can access the partitions in live environment I can't even install a fresh OS because It also shows 500GB unallocated space.

General :: Untouchable Disks Via Disk Utility And GParted

May 26, 2011

I have what I think are hybrid GUID/MBR disks that I created by splitting already MBR/NTFS disks via GParted, leaving unallocated space, then creating HFS partitions within OS X from the unallocated space on them.I want to delete those HFS partitions and re-extend the NTFS on them, but I can't because GParted sees the disk as somehow unchangeable; I assume OS X has done something to them.I now can't extend or do anything to the disks via the OS X Disk Utility OR GParted. What can I do?

Software :: Disk Caching Utility For Power Saving ?

Nov 28, 2010

I run Ubuntu Netbook 10.04 on my EeePC 1005HA. I'm going to get a SSD for it eventually, but I can't afford one right now so it's running from a 200GB hard disk I scavenged off a dead laptop.

I went in power management and set the option that says "spin down hard drives whenever possible", but this accomplished a whole lot of nothing - whenever the computer is on, the drive's spinning. I ran hdparm -y and the drive clicked off, and then promptly spun back up after a few seconds. Iotop shows occasional tiny bursts of activity from "jdb2/sda1-8", which I don't really know how to interpret, but I don't have anything weird installed so I'm assuming this is normal system operation.

Now, what I need is some sort of application, utility, command - anything - that forces the computer to keep all filesystem changes in RAM with the drive shut down; every five/ten minutes or so (this would hopefully be configurable) it spins up the drive, dumps the filesystem changes to it, and spins it down again.

I realize this presents data loss risks related to crashing and poweroffs when the cache hasn't been dumped to disk, but I'm willing to risk it as Linux never really crashes at all, and since it's a netbook power failures won't cause unexpected shutdowns.

Ubuntu :: Windows Drives Are Not Appearing And Disk Utility Shows Spaces Above The Capacity Of HDD

May 21, 2011

I had installed Ubuntu 10.04 on dual boot mode with Windows 7, I had to migrate from windows 7 to XP & again to windows 7. Each time after installation I updated grub. Last time while updating Grub PC went Down due to power failure. I update grub after the supply was resumed and it was successful.

On login I am facing a weird problem, My windows Drive are not appearing in Ubuntu. To access the drives I have to Plug a Pen Drive and access them first from an Application otherwise the don't even appear in Places drop-down list. If I don't plug Pen Drive they don't appear in Applications.

The other problem is that Disk utility shows space unallocated, allocated & Free above the physical capacity of Hard disk. My Hard disk is of 160 GB, Disk utility Shows Unallocated Space 18446744 TB. The Default Partitions made by me are 26GB, 14GB & others of 40 GB each.
