I got gigabyte chipset with an raid support. Currently I have 2 hdd's running in raid 1. When I was first installing ubuntu 11.04 server my fakeraid was detected, and I assigned a name for it in the initial installer and it was auto-mounted (working 100%) ever since.
However I was forced to reinstall my ubuntu server, and this part was somehow skipped in the installer.
HDD can still be seen in /dev/mapper
I can see
control
jmicron_GRAID -> ../dm-0
jmicron_GRAID1 -> ../dm-1
I'm trying to rescue files from an Iomega NAS device that seems to be corrupted. This is the Storcenter rack-mount server - four 1tb drives, celeron, 1gb, etc. I'm hoping there's a live distro that would allow me to mount the RAID volume in order to determine if my files are accessible. Ubuntu 10.10 nearly got me there but reported "Not enough components available to start the RAID Array".
I have a full working Mythbuntu 11.04 on a FakeRAID system (via ICH10R chipset). The OS is sitting on a 250GB partition and working fine. I am trying to get the 7.07TB partition mounted so that I can use it to store all my movies. When I mount it via the [URL] all works fine. When I reboot it cannot mount due to device being not ready or unavailable It appears the superblock goes missing at reboot. I have it formatted to ext4 with a GPT partition table. If I reformat and remount then all works fine again until I reboot.
i have purchased sun server for my visualization project. Request you to help me finding the io for disk .I have put storage(disks) on different location (File Server) and on server (Application) i have configured 4 virtual machines.
How would i monitor the io for file server from the Application server where i have configured 4 virtual machine. one way to mount the file server share on application server and execute
dd if=/dev/zero of=/share/test.out bs=1024 count=1024 to check the read and write Is there any other way of doing this.
I have installed Ubuntu 9.10 (64 bit) as a dual-boot setup (along with Win 7) on my desktop. I can't emphasize how much faster Ubuntu loads when compared with Windows. There is only one problem though, I cannot figure out how to use my existing FakeRaid array (two 2TB hdds setup as RAID 1 - mirroring) to work with Ubuntu. I am NOT trying to install Ubuntu onto a raid array (I have Win 7 mounted on a separate boot drive , 4 hdds altogether, two for each OS and two for the RAID array). The raid array works fine in Windows and it's an Intel Raid Controller. How can I do the same for Ubuntu without losing any data? Is this possible?
I have just installed Ubuntu 10.10 server on and old pc to use it as a backup server for my and my kids pc's.The pc I use for the Ubuntu server has two sata disks on a fasttrak 378 controller, fakeraid as I have learned, and a single pata disk. I have installed ubuntu on the single pata disk and was planing to use the fakeraid as the samba share.
I have an MSI 845E Max Motherboard. I just purchased the computer USED. I have no manual and from all accounts of the online manual, this MB is doing the impossible.Connected to this MB are 2 WD 60GB hard drives. Bother are recognized in the bios. When booting from the live CD, and running the disk utility I can plainly see that there are the 2 drives and one striped array (using both of those drives).There is no settings in BIOS for any array. If I remove 1 of the drives, the disk utility sees only 1 drive but still sees an array. I can find no way to eliminate, recreate, oe manipulate this array in any way.To make matters worse, I attempted to install an older FREEBSD, using it it saw both drives (no raid). Using their Disk utility I re-partitioned both drives and continued the install. Unfortunately the version I had was an older one and it could not complete the FTP install (And I would rather have Ubuntu anyways). Though through this action I believe that I have destroyed the integetery of the raid and if it is to be used it needs to be fixed.So.. how do I fix something that my BIOS is not supposed to be capable of doing? Has anyone else experienced this issue.
My motherboard has a BIOS feature to support RAID1 for two disks. I know it's FakeRAID but that's what Windows can work with. I've read that Linux's built in softraid mdadm is better so I'd prefer to use that for Linux's own filesystems. Can I enable FakeRAID in the BIOS without it affecting Linux in any way? Is it possible for Ubuntu to read and/or write to the NTFS partition that's raided with the fakeraid?
Also, if running mdadm in RAID 1 how much risk is there of losing data if the computer crashes? Is e2fsck able to repair a filesystem on a RAID 1 setup?
I wanted to install Ubuntu 11.04 on my pc (dual boot with windows xp which is already installed on one disk). I have a Asus P5K pro (motherboard) which has a integrated raid controller and i have two 500 GB hard disks. On BIOS raid is disabled. On Windows i see 2 different disks (correctly).. When i try to install Ubuntu, on the disk/partition stagei only see /dev/mapper/xxxxxx which should be the raid (i could be wrong). I tried booting inserting the nodmraid option but if i do i cannot see any disk.
I have a HP Microserver which uses what I thought was a hardware RAID. It now turns out that it is fakeRAID.
I'm moving from Windows 2008 so currently I have 2x2TB disks in a RAID1 and formatted to NTFS. The RAID was working fine on Windows but it doesn't seem to work on Ubuntu. I have over 1.3TB of data currently on the RAID so I cannot format and start again. I need to find some way of getting Ubuntu to mount this RAID without having to format and create a software raid.
I'm unsure why it presents itself to Ubuntu as two separate disks as the RAID was setup on the RAID Array controller before it starts to load the operating system. Windows sees the RAID as a single disk and not two separate disks (although it can if I use a disk manager).
After some digging I have found out that the RAID format is PDC because Ubuntu can see the two disks and knows that they should be in a RAID but does not want to activate them. I don't want to go any further and experiment with commands until someone responds because I'd rather not risk my data.
Code: chris@Chris-Server:~$ sudo fdisk -l Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
I have 2x320gb drives that i want to use as a system disk. Should i use intels ICH10r on motherboard or can i do a software raid on install...I don't want to buy a hardware raid controller.
So I am trying to install ubuntu server on to a sony vaio laptop (long story in and of itself) I have a few questions the first and most important being this: 1. What is the module and /dev/ I am supposed to use to get it to recognize the drive? It kind of dumb because it can't read the drive that it's installing from ya'know? The drive is a sony nec optiarc AD-7560S the vaio is a VGN-NS110E all stock equip except the hardrive.
2. Keeping in mind that I may..probably will move the hdd to a netbook what are ALL the module I will need to finish the install and how do I add them in (can I use a usb or do I have to re-burn the iso)
3. What do I need to do to get the built in remote desktop to run once the install is done and most of the software is taken care of. Also I need to be able to install stuff from the remote computer and said remote computer may be holding the program. I am also looking into rdc-ing from my andriod (tmobile g1)
I continue to have issues installing any of the newer version of Ubuntu on my ICH9 FAKERAID. I read that the GRUB2 issue with FAKERAID was solved shortly after Karmic was released. Did this somehow not get added to the Alpha 1 and Alpha 2 of Lucid? I would love to have Ubuntu installed on my main rig, but I do not want to fuss around with it forever...
I'm using Karmic koala 9.10 64bit.Have three HDD, WD Raptor 36GB X 2 and Seagate 160GB.2 WD Raptors are striped (RAID 0), and all hdds are formatted by ext4.(Intel ICH9R raid) Problem is that, when reading/writing hdd heavily, system freezes a moment or very very slow down. When I used a windows XP, there's no problem. Moreover, one other machine, Karmic Koala 9.10 64bit and ext3, no raid, works very fine.
My system consists of, Intel C2Q Q6600 2GB DDR2 6400 (1GB X 2) Gigabyte P35-DS3R Geforce 8500GT 256MB
[Code]...
If I format my hdd and re-install ubuntu, does it become better? or, if I use software raid provided by linux kernel, or if i don't use a raid?
I've been searching for a solution get mount my NTFS FakeRAID automatically when 9.10 64-bit starts, but haven't managed to find a solution.Currently, after boot, dmraid activates my RAID automatically but does not map the partitions on the drive:
Code: $ ls /dev/mapper/ control isw_bibdafajea_Vault
Gparted does not recognize my intel ICH7 fake raid 0 partitions rendering it useless. Am I missing a package that will add this? I know the live disk can do this. Is it something to do with dmraid? using 10.04 64 bit ubuntu
I have 2 750GB harddrives with multiple NTFS and ext3 partitions and have just added two empty 1.5TB drives (with WD Advanced Format Technology) to the computer. I have several external drives of various capacities for temporary data storage. My final objective is to have two mirrored RAID arrays that I can access with both Ubuntu 10.04 and Windows Vista (which I still need for applications that aren't supported by WINE), and I'm trying to find out how to do this.
At the moment, the 1.5TB disks are mirrored in the BIOS settings, and I was able to add a blank NTFS partition to the array using GParted. However, I am now unable to mount any of my partitions (other than the Ubuntu one) and cannot use GParted to copy a partition to the RAID array (I get a generic resource in use message, but I have no other applications open and am opening GParted after a fresh boot).
My Ubuntu install is heavily customized, so I would prefer not to reinstall it if at all possible. If it matters, the OS was not installed as 10.04, but was updated incrementally over time, starting at Hardy Heron. I initially did an apt-get install of dmraid and kpartx after reading [URL]
For some reason, my 750GB drives are recognized as belonging to a broken RAID array even though they are not set up that way in BIOS.
HD configuration:
sda: (I cannot mount any of these partitions ) 1: ext3 (Debian Installation) 2: ntfs (Vista Installation) 3: ntfs (Data)
We can mount one NFS server just fine, but if we try mounting a share from another NFS server on the same domain we are unable to. We are using Fedora 10. Has anyone run into a problem trying to mount an exported share folder from an NFS server. Some of us get access denied and we've chmod 777 on the exported folder. The export file contains: /labdocs 192.168.1.0/24(rw, sync, no_root_squash)
And that's it. We run exportfs -a -v and it shows up fine. On one of the client systems we try to mount the folder on a directory created by root mkdir /docs mount 192.168.1.13:/labdocs /docs it either hangs or displays a message access denied.
I can't get CentOS to stop seeing my drives as a fakeraid, even though I disabled the raid settings in the bios. Therefore, I can't install. Previously, this box was running Vista 64 bit. I have an nVidia mainboard and two 500 GB sata drives. The mainboard offered raid support, so I enabled it. Windows saw the drives as a single raid0 drive and installed on it flawlessly. Never had a problem. Two days ago, I finally got off my horse and decided to get rid of windows and install CentOS. I left the raid intact, installed CentOS on the fake raid. Upon rebooting, GRUB wouldn't load. Booted up a live disk, fdisk saw the drives separately but couldn't read data from them.
Tried a second install, same problem. Wiped out the the data on the drives using gparted. Tried a third install, same problem. Did some research, found out that my raid was really a fakeraid and that a better option for my needs is a softraid. Disabled the fakeraid in the bios. Booted up the installer. It still loads the nvidia /dev/mapper driver. It still sees the drives as a fakeraid. Wiped out the drives using gparted. Booted up the installer. Still sees the drives as a single /dev/mapper/nvidia_lkjwer drive. Installed Ubuntu to see if I'm crazy, or if it's centOS. Ubuntu installed w/o a problem (on a single drive). Enabled, disabled, tweaked every freaking possible bios setting. Still sees the drives as a fakeraid.
I've tried to get an opensuse box I have to share a directory via NFS. I've failed each time, but I thought that the third time, I'd enlist some help from the forums, if I could. how do I know that the nfs server and not the client is the problem? Short answer is: I don't! That's why nfs (and many netwrk problems) are laborious, you're troubleshooting needs to take place at both source and desitination. Next question, what do I have set up so far? Well, I did download the nfs server kernel stuff (two months back) and /etc/init.d/nfsserver start seems to get set up OK. No errors and the daemons nfsd, idmapd, mountd area all running. So, I *think* that part is OK. I have the share set up properly in /etc/exportfs and have "exportfs -r" it.
OK, now onto the trickier stuff: the client and iptables. On the client pinging to the nfserver box is perfect, and I have rpcbind running. the reported error is "mount.nfs: mount system call failed" though from experience nfs errors don't mean a whole lot.However, I will go off and check now and see if I need a mountd running on client-side too.Then there's iptables .... ouch, that could be a long and painful trek. I don't see any specific ports being blocked, and it's the iptables that the default v11.2 opensuse came with. I did turn them off and the problem was the same, so whether wishfl thinking or not, I'm hoping it's not an iptables issue.
About a year ago I bought a new compy and decided to get on-motherboard RAID, and by golly I was gonna use it, even if it wasn't worth it.
Well, after one year, two upgrades, a lot of random problems dealing with RAID support, and a lot of articles read, I have come to my senses.
The problem: I have a fakeraid using dmraid, RAID 1, two SATA harddrives. They are mirrors of eachother, including separate home and root partitions. I actually found the method I think I had used here: [URL]
The ideal solution: No need to reinstall, no need of another drive, no need to format.
My last resort: Buy a drive, copy my home directory, start from scratch, copy my stuff over.
i have installed nfs server on my redhat machine.when i want to mount shared data from client(suse)machine the following error occur."mount.nfs: mount to NFS server '10.3.31.146:/home/usbtest' failed: System Error: No route to host"
I have servers installed with RHEL 4 2.6.9-89.0.9 ELsmp. I tried using uuid and label in /etc/fstab to automount usb drives to mountpoints that I specify after reboot. Unfortunately, it just does not work in all my RHEL4 servers. After every reboot, /etc/fstab will be automatically modified and all configurations related to my USB drives will be changed. Irregardless of whether i use UUID or LABEL in my /etc/fstab.However, it works on RHEL5. But, upgrading is not an option in my environment. I have been googling around looking for alternatives but everything seems to point back to using UUID or LABEL in /etc/fstab. Anyone has tried something that works? Please help me, thank you.
Using NFS on the client machine. I am running scientific linux on my machine. Its working fine for my other machines.I have made sure that the firewall is disabled and also the selinux too. here is what i get when i use rpcinfo -p on the client.

I built a Suse Linux server on vmware. I attached an RDM to the server and can now see the drive as a "Mass Storage Drive" in Applications - computer. When I double click on the icon, I get an error message that indicates that the drive can not be mounted. I tried to mount in gnome terminal using: mount /dev/sdb and get "can't find .dev/sdb in /etc/fstab or /etc/mtab". I tried adding device that I would like to mount to fstab, but don't think I have the settings correct. I looking for any info that might step me through the process.
I have a HDD that cannot be bootup (should be the boot file problem, I want to get back the data in it, so I plug it to another server and trying to copy the data from the failure HDD to this server. Now, the server is re-boot and in maintenance mode as the HDD cannot do the system check. when I try to copy data, it pops the server is read-only system. 1. How to let me write data to the server ; or 2. Let me boot up the server, then I will mount the HDD to it and copy the data to the server.
I had Ubuntu 8.04 installed on server#1 and moved it to server#2. Everything works fine, including the changing of eth2/3 back to eth0/1. I was wondering if it's possible to use the nvidia onboard raid and make a raid 1 with this OS not getting wiped out. It's a bios level cheesy raid and it warns that it's erasing the data (which is didn't erase), but wont boot anyway. I'm assuming it's probably best to just create a software raid in the working OS with a fresh 2nd drive.
I'm looking to shrink my windows partition on a raid0 array and create a mdadm ubuntu partition using raid0. Is this possible? can I just ignore the /dev/mapper device and use the standard /dev/sdx devices?
