I have a remote server so the only access I have is through SSH, the datacenter where the server is located(leaseweb) say they cannot setup software raid configurations but also say it is possible to do myself.
Four disks are attached to the server with only one partitioned, now how can I setup a software raid configuration with these disks, am I correct in thinking this can only be done with the use of a kickstart script?
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.
Could 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 am looking to convert a raid 1 server I have to raid 10. It is using software raid, currently I have 3 drives in raid 1. Is it possible to boot into centos rescue, stop the raid 1 array. Then create the raid 10 with 4 drives, 3 of which still has the raid 1 metadata, will mdadm be able to figure it out and resync properly keeping my data? or is there a better way to do it?
View 2 Replies View RelatedI have a box that doesn't have a Raid controller or a software raid running currently. I would like to make it a RAID 1. Since it seems there isn't any IDE RAID controllers hardly around, I have another HD that is the exact model as the drive currently in the box running CentOS. Can I some how add the second drive and get the box to mirror from here own out? The box gets really hot and I want to be ready for a HD failure.

View 1 Replies View RelatedHere is my system: I have dell poweredge 1950 PERC 6 with 300 GB raid system. It has two disks of each 300GB RAID mirrored system. I have few applications and data that reached around 280GB. As you know, poweredge 1950 we can have only two disk.
They are not mission critical. Hence, I wanted to remove the raid system and use as a non-raid system. By doing it, The applications and data can grow upto 600GB. I do not want to loose the data and setup. I am not so clear about RAID system and its conversion.
I have a low powered headless box (DLINK DNS323) running linux that I keep in a back room at home to handle large file downloads. It does not have X installed. Everything is handled at the command prompt through an SSH link. In the most common case, I log in from a remote location (perhaps a coffee shop), start the download, then disconnect and go about my business.
If I try to download from a free account of rapidshare, filesonic, or some another file service there is a manual handshake process (decode a captcha, wait for 60 seconds, etc) that requires a graphical client to complete.
I would like to somehow navigate through the handshake using my laptop (running Firefox) (perhaps through a proxy on the DNS323), but direct the download directly to the DNS323 (i.e., not routed through the laptop) so that I can disconnect and expect that the download will complete without further involvement from me or my laptop.
Is there anyway to direct a download to a remote path? Any other suggestions for solving the problem?
I am running single drive Ubuntu server 9.10 with a lot of software. Now I want to add one more disk (same size and type) and to convert this to RAID 0 without need of reinsallation. Is it possible and if yes how? I didn't find nothing for RAID 0. It sounds simple, but probably is not.

I have a problem configuring a RAID server under Ubuntu 9.10 (kernel 2.6.31.17) with mdadm (v2.6.7.1). First I had some hardware issues that finally got solved by using another motherboard. Now I am dealing with the software part.In order to ease things, I am trying to configure a RAID 5 with three partitions in one disk. I have two HD's, one IDE where the OS lies (recognized as sda), and another where I intend to build the RAID (recognized as sdb). In this second drive I have made three partitions (sdb1, sdb2 & sdb3) of the same size.I've already re-installed Ubuntu 9.10 a couple of times, zeroed the superblocks of the partitions, repartitioned the disks with different partition sizes (I am using 5 GB partitions to save time). I've gone through this process several times, and I really don't know how to move forward now. If RAID is about trust and reliability, this is exactly what I'm not able to get.
View 5 Replies View RelatedI support a small business which runs a headless Ubuntu Server (10.04 32bit) as a file server which is accessed by Windows machines.Although the company has it's own back-up procedure they have decided to back-up some (none sensitive) files online. The have chosen FileFactory (http://www.filefactory.com/) as the host for this. FileFactory allows files to be uploaded to their server by FTP however I do not know how to set this up on the server.
The idea, if it is possible, is to connect to FileFactory through FTP and then synchronise the data using an Rsync command.I normally access the server through Webmin and it has vsFTP installed. I can access the company's server by FTP from inside and outside of the network so I know that vsFTP is working for incomming connections however I cannot work out how to configure it to connect to the FileFactory server.

The issue is that my CentOS workstation is in a vlan from where the Intranet's DNS servers are unreachable. For browsing the web there is an ISA proxy server, which I presume resolves DNS for my firefox. However, wget, host, ping and aria2c fail to get any sort of DNS resolution since they're being run from command line.I have exported HTTP_PROXY value, which provides me internet access on console, but,only when I connect using IP address. It fails on name resolution.
My question is:May I redirect the DNS queries to my home PC which would be running a DNS server on a non standard port?I was thinking of putting nameserver 127.0.0.1 in /etc/resolv.conf and then put iptables rule to redirect 127.0.0.1:53 UDP to a.public.ip.address:3535 UDP..I don't know if I am shooting blanks or what, I am not very much aware of this kind of setup.My main need is to provide DNS resolution to console apps.I want to utilize my company's idle bandwidth for bulk downloads, so, using proxy, SSH tunneling through my Home PC is out of question.

I have a new home server I built this weekend with 4 x 320 GB Seagate Barracuda SATA drives. I am going to load my O.S. this week however I don't have a RAID controller so I would like to utilize 'Software RAID' via 'mdadm' package. My question is since this is a general home server with no specific function rather than hold my data reliabily and resonably fast, how do you guys recommend I configure my partitions for RAID? What level would be best with my 4 drive configuration? RAID5 or RAID10? Should I use a 3 drive RAID and use the 4th as a spare? Please let me know what you recommend as I don't have a lot of expertise with what is not practical or useless when it comes to Mdadm RAID.

View 6 Replies View RelatedI am implementing an automated backup scheme so I created a shell script which first creates SQL dumps for all MySQL databases, then retrieves all websites from the /var/www directory of a remote server. The latter is working as I am using rsync to get the remote files.However, the MySQL dumps being retrieved are the ones from the local server which is not what I want. I want to get the SQL dumps from the remote server as well.I have a tunnel between the local and remote server which I can connect to without using any password (I added the public key to the authorized_hosts), so I tried to add the following code to the script:
ssh user@192.168.x.xxx
I then attempted to retrieve the SQL dumps and exited from the remote server. However this does not work as I still have to enter exit manually in the terminal for the SQL dumps to be retrieved from the remote host. I don't know why this is happening. This is what the script is trying to do:
//connect to remote server
ssh user@192.168.x.xxx
//retrieve SQL dumps
