I have been having problem with my failed disk RAID server.
The regular mdadm --assemble cmd does not work.
After trial&error, I am able to add all disks to the RAID using mdadm.
However, it is still inactive. How do I activate this RAID md0?
The result from cat /proc/mdstat
Code:
I've got a file server with two RAID volumes. The one in question is 6 1TB SATA drives in a RAID6 configuration. I recently thought one drive was becoming faulty, so I removed it from the set. After running some stress tests, I determined my underlying problem hadn't cleared up. I added the disk back, which started the resync. Later on, the underlying problem caused another lock up. After a hard-reboot, the array will not start. I'm out of ideas on how to kick this over.
Code:
$ cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]

migrate an installed Ubuntu system from a software raid to a hardware raid on the same machine? how would you go about doing so?
View 1 Replies View RelatedCould any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:
mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]
I was able to examine the disks though:
Code:
root@127.0.0.1:/etc# mdadm --examine /dev/sdb2
/dev/sdb2:
Magic : a92b4efc
Version : 00.90.00
code....
Code:
mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2
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 was told to login using my root, but from where i am at i can't open gedit and allow my root to be used. if that makes any since.

I've set limits in limits.conf but they don't seem to be having an effect (the easiest to test is maxlogins). Do I need to do something to enable the limits?:wqEDIT: old postI know you can have file system quotas, is there any way to set a similar quota for CPU usage for particular users so that they can't hog all the system resources (either intentionally or accidentally)?A preliminary Google search is suggesting it's not possible, but I can't believe thatOk, limits.conf and pam... I used bad search terms apparently. Now I just need to figure out how to use this stuff, but that shouldn't be an issue.

I've seen Dwell Click under accessibility options, but that doesn't seem to do anything. I know that sometimes the GUI control applets have features undisabled that don't really do anything (i.e. WINS) if you don't have the right stuff installed. How do I get mouse over pretty much just simulate clicking the window.

Slackware 13 install on my Samsung R60+ laptop "startx" gets me into KDE no problems, so there's a reasonably familiar GUI to muck around in, but I think that I'll need help getting the wireless networking going. It would be nice to do this in KDE, but I don't think it's going to be possible at the moment. Running netconfig was confusing, as I've never had to do it before. So imagine if you will:
I've just booted Slackware. I'm sitting, logged in as root for the time being, at the command prompt. I'd like to get my wireless card (Atheros AR5007EG) working. Can anyone walk me through the commands I'll need to execute (bear in mind that I don't even know how to edit a config file yet) in order to get this thing on the internet? I've tried reading the docs (slackbook) and googling, but with no luck so far - I don't understand what they're on about! Win7 does this for me.
I've an Acer Aspire One A110 Netbook running Linpus Lite. All seems relatively well however I've plugged in a Bluetooth USB dongle and nothing has happened - oh well, I didn;t expect it to. Of course I'm used to MS Windows OS plug 'n Play and I know this isn't generally how Linpus Lite OS operates but despite looking around I can't find an explanation on how to activate the Bluetooth adapter. There are instructions and demos on how to add a Bluetooth component to the board but I'm not an engineer, neither professional nor hobbyist, so Im not interested in doing that. I've downloaded the Bluetooth zip file from the Acer Spire One support site it has been installed on the Netbook but there still appears to be no Bluetooth connection.

View 3 Replies View RelatedI am running fedora vm under XP host and using NAT connection to the Internet. It usually works fine, but some time the connection is just lost. I went menu System->Admin->Network and see the interface eth0, but I cannot activate or deactivate. The status is inactive. (when the connect works, the status is active). so I try "ifdown eth0" and "ifup eth0" command, and got
"Error: Connection activation failed: Device not managed by NetowrkManger
The menu System->Admin->Network device control show no interface.
I am not sure what happened.
1) how do i access my windows7 partition
2) How do i activate my wireless? The light on my lapptop that says my wireless card is on.
Using a Eee 900A netbook by Asus. By pressing Fn + F2, I can disable or enable the wireless chip on the netbook, a blue LED indicates the status. I've been able to connect to wireless networks just fine with this netbook. However, if the wireless chip ever becomes disabled, I have to reboot to get my network connection back. This generally happens when suspending. For some reason the LED will be off and I have to hit Fn + F2 for it to light up again.
However, after doing so, Linux will not reconnect to the network. It simply changes the wireless status from "wireless is disabled" to "device not ready". Even worse, I've recently had issues with the chip being enabled at boot, thus making it nearly impossible to get connected. I've searched around on-line but haven't found much of anything useful on this. This happens on all kinds of different distros including Ubuntu 9.10 Netbook, EeeBuntu 4 beta, Jolicloud and Ubuntu 10.04 Netbook.

I have changed the preference in the Nautilus file manager/browser to "Single click to activate items" and it works.
However, when I run an application, say Totem Movie Player, and select Movie/Open I am presented with a Nautilus like file navigation dialog. This is a common dialog to most Gnome applications - probably part of Gnome. Problem is, the dialog does not respect my "single click..." preference.
I have tested this in Ubuntu 9.10, 10.04 alpha 2 and CentOS 5.4 - I do not think it is distribution related.
I have a raid5 on 10 disk, 750gb and it have worked fine with grub for a long time with ubuntu 10.04 lts. A couple of days ago I added a disk to the raid, growd it and then resized it.. BUT, I started the resize-process on a terminal on another computer, and after some time my girlfriend powered down that computer!
So the resize process cancelled in the middle and i couldn't acess any of the HDDs so I rebooted the server.
Now the problem, the system is not booting up, simple black with a blinking line. Used a rescue CD to boot it up, finised the resize-process and the raid seems to be working fine so I tried to boot normal again. Same problem. Rescue cd, updated grub, got several errors: error: unsupported RAID version: 0.91. I have tried to purge grub, grub-pc, grub commmon, removed /boot/grub and installed grub again. Same problem.
I have tried to erased mbr (# dd if=/dev/null of=/dev/sdX bs=446 count=1) on sda (ide disk, system), sdb (sata, new raid disk). Same problem. Removed and reinstalled ubuntu 11.04 and is now getting error: no such device: (hdd id). Again tried to reinstall grub on both sda and sdb, no luck. update-grub is still generating error about raid id 0.91 and is back on a blinking line on normal boot. When you'r resizeing a raid MDADM changed the ID from 0.90 to 0.91 to prevent something that happend happened. But since I have completed the resize-process MDADM have indeed changed the ID back to 0.90 on all disks.
I have also tried to follow a howto on a similar problem with a patch on [URL] But I cant compile, various error about dpkg. So my problem is, I cant get grub to work. It just gives me a blinking line and unsupported RAID version: 0.91.
How long does hardware Raid card (raid 1, 2 drives)take to mirror a 1 TB drive (500gb used)?Is there a general rule of thumb for this?4 hours? 12 hours? 24 hours?
View 1 Replies View RelatedI am trying to connect a RAID Box to the server via LSI 8880EM2 RAID controller.The raid box is FUjitsu Externus DX60 with raid 1 configured.The server is Fujitsu Primergy SX300 S5 with LSI 8880EM2 RAID card.The external raid box is being recognised by the raid controllers bios.
The server runs CentOS 5.5 64bit. I have installed the megaraid_sas driver from LSI website and MegaCLI utility but CentOS still fails to see the box.MegaCLI utility, when launched from CentOS, recognises the raid box, CentOS does not(no mapping being created in /dev).
I have also tried to create a logical RAID0 HDD on one physical HDD(as seen by MegaCLI) with MegaCLI utility in CentOS.The result was success and the new logical drive could have been used, but when restarting the server, the controllers' bios fails with an error (not surprised(one logical RAID0 on one physical HDD)) and configuration is being erased.
Has anyone tried connecting 8880EM2 controller to a raid box with raid configured on the box, running it all under CentOS and what were the results.
I have installed Ubuntu on my m1530 since 8.04 and currently dual boot Win7 and 10.10. I would like to dual boot on my PC, but I have run into a problem. I am not a pro at Ubuntu, but this problem I can not solve by reading forums like I have in the past.
I realize this is a common problem, but I have noticed people having success.
I have a M4A87TD EVO MB with two Seagate drives in Raid 0. (The raid controller is a SB850 on that MB) I use the raid utility to create the raid drive that Windows7x64 uses. I have 2 partitions and 1 unused space. Partition 1 is Windows, partition 2 is for media, and the remaining unused space is for Ubuntu.
I am running ubuntu-10.10-desktop-amd64 off a Cruzer 16GB flash drive that was installed via Universal-USB-Installer-1.8.1.4.
My problem like so many others is that when I load into Ubuntu, gparted detects two separate hard drives instead of the raid. I read that this is because kpartx is not installed on 10.10. I then went in LiveCD mode and downloaded kpartx from Synaptic Manager. Gparted still reported two drives. I opened terminal and run a few commands with kpartx. I received an error. (Forgive me I didn't write it down, but I believe it said something about a communication error. I will try again later and see.)
Currently I am reflashing the Cruzer with a persistence of 4GB. I am not familiar with this process, but I understand that my LiveCD boot will save information I download to it. I decided to try this method because I was going to install kpartx and reboot to see if this made a difference.
I am looking for any suggestions on a different method or perhaps someone to tell me that the raid controller or some hardware isn't supported. I did install ubuntu-10.10-alternate-amd64 on my flash drive, but fail to get past detecting my CD-ROM drive since it's not plugged in. If this method is viable, I will plug it in. I also watched the ..... video were a guy creates Raid 0 with the alternated CD, but it wasn't a dual boot and didn't use a raid controller from a MB.
how can I create RAID 1+0 using two drives (one is with data and second one is new). Is it possible to synchronize data drive with empty drive and create RAID 1+0 ?
