Hi Everyone,
We are using Dell Power Edge R510 server as a central storage in Linux network. I have configured RAID6 on 10 near-line SAS hard disks. Using NFS i have exported one directory and mounted it on other machines.
Recently we are facing one problem, when anyone read/write big file (2-3GB)from NFS drive,others feel very slow access to that drive. Sometime we can't open simple text file till complete read/write process.
I have remounted NFS drive but still problem as it is.
Can anyone help me to solve this problem.
Lots of posts on internet about flash drives ending up read-only in Linux after using on a windows or mac systme. Gather it is a problem with incorrectly ejecting or the ejection being poorly done.
Usually I can go back to the box and re-eject and all is well. This time even GParted and the resident fedora 21 Disk Utility programs did not even see the drive (which Was visible under "files").
Using disk utility on the "offending" machine, it seems there were many files that were truncated (due to some eject issue? Note the ejection was done "according to Hoyle" ); regardless the flash drive was still read-only. Howeverk, re-trying GParted, which now recognized the drive, the drive was unmounted checked. Some repair was necessary. Currently, I can read, write and copy within the drive.
However, the drive itself is still only read-only for all but the owner (which is not even root). I cannot copy any file to the flash drive. Chmod does nothing (no matter if root or other user tries). I suppose I should be satisfied for the access there is, but if anyone has any more suggestions, it would be great.
Thanks in advance for any info/interest
hi guys,
i want to back up my centos server that has a few virtual machines on it...i read that some people were saying dd is a very good way to do this. but a lot of people dont cause of fear of the command line.
i would like to write a script that backus up the entire hard drive to a ext usb hard drive.
i have a couple of questions though.
1) am i better off using a cloning software like acronis or storage craft.
2) can dd also restore a system to a bootable state or is it really just a backup.
3) can you still use the system while it is backing up?
thanks...
I have tried to put Linux Mint 17.1 on a 500 gig HD (IDE) from
a DVD ISO. The file loads ok but will not complete loading. The
HD drive light stays on solid until I must shut off computer with
power button. Has anyone else run into this problem?
thanks Cliff
Using a Kingston 4GB datatraveler for drive creation
Created using amd64 1.1.0a of the Kali ISO verified from Kali.org
Drive created using Ubuntu 14.04 on a Dell Latitude E5500
dd seems to create the drive with no errors. The drive boots to the error. Hard reboot into Ubuntu to search for solution has led me to a long series of issues that I have been trying to correct.
A possible fix for the failed to load error is to copy the file to the root of the USB drive (/dev/sdb1). Drive is created with a hidden HPFS/ NTFS fs. 0x17. Changed FS to HPFS/NTS (0x07). Drive now mounts, but when attempting to copy onto drive, I get an error that the file system is read only.
I try to correct the issue using nautilus and the properties menu. It does not allow me to change the view only to read/write even though it shows me as the owner.
I think maybe a command line thing would work, or who knows what else. Maybe an fstab entry? I am continuing to search the web, and hope to work this out.
Any help would be appreciated.
Hi, all, I am new to the forum and quite new to Linux, I am running Mint and Kali from a USB drive, all is going well with with the software and I am starting to find my way around it.
So, now to my question, I have 15 machines which all run from a CF card and the card has multiple partitions and is a Windows Embedded XP, not that the operating system makes any difference, I need to upgrade all the CF cards from 2gb to 4gb, so unfortunately Windows isn't an option to use to copy the drives as it doesn't recognise multiple partitions on a removable drive, so I cant just remove the drive, clone it and fit the new one.
What I need is a method of cloning the drive completely with both partitions, I have read about dd but cant seem to see anything about doing this with multiple partitions, as Linux sees it as two drives when I plug it in, how can I use dd or anything else to clone the drive which is bootable and has two partitions?
At some point I would like to automate the process as I could have many of these machines/drives to upgrade, is there a way to write a program that will automatically back up the drives from a USB drive and then reinstall it, I have seen this done before but I am not sure if this method did the whole drive, just the main drive or all partitions?
A week ago, I realized that I could not boot live disks. At first, I thought that it was the optical drive not writing the disks correctly, but when I tried two live disks that I've used many times before nothing happened with those either.
I have CD/DVD drive listed first in my BIOS' boot order and I even tried selecting the optical drive in the menu when the computer started and it still does not boot a disk. Thankfully, my somewhat old hard drives are still chugging along but I need to be able to use a live disk, in case one or both die on me.
My question is, how can I know for sure what the problem is? Is there a way to test the optical drive (Samsung Super Writemaster - which has a bad rep)? Could it be my motherboard. It was bought new 2 years ago, and there are no other issues with it. Also, I have been able to create playable DVDs on my computer with the Optical drive that work perfectly on my Bluray player, yet I cannot play the movies or open a data disk in file manager on my computer. What does that mean?
I want to know that it's worth it to buy another burner, before shelling out the money when I'm already practically broke from Christmas gift purchases. Any suggestions on how to test the optical drive would be appreciated.
Want to format a 1 TB Western Digital drive in an old dell 32 bit machine. Machine has Lubuntu installed and a Virtual machine on which which is loaded Windows 7 (32 bit).
Machine does not "see" the new 1 TB (SATA) drive after I physically install it in the machine.
I have other windows and Linux machines. I have some drive cradles in which I can connect to (windows) USB ports.
Is it possible to use the old Dell machine to format the new drive?
(It appears that this question has been answered before. So I will check those materials as well.)
Thanks for any assistance.

I am trying to create a combined media and storage server (NAS) on my new Unbuntu server. I have a 256GB drive as my boot drive and I have two 1TB drives that are empty. I want to use the two 1TB drives as storage for some important data and also for the media that will be played/collected for my XMBC server. I want to be able to access/manipulate these shares/files/data from my Windows computers over my home network.
I have Unbuntu 14.04 and Webmin installed.
I greatly appreciate any assistance. I feel like I am running around in circles on Webmin with this.
Hi,
Could anyone please explain as understandable as possible how could I on my Windows 8 open either single file or install (and use) entire software which is supposted to work on Linux and/or Ubuntu? I have absolutelly NO experience with Linux and have never used it. Honestly, I don't know if there is any difference between Linux and Ubuntu. I want to be inside my Windows 8 while using Linux files/sofware. The only solution I could think of are actually two but neither of them is useful for me:
1. Vmware (i don't know how to use it)
2. Rent remote computer (vps/rdp) with linux OS installed (this would let me be in Windows 8 while being able to use Linux file/software [on remote computer] but sooner or later I would want to have Windows installed there too)
Tried program Linux Reader but didn't work on my Windows 8. Although I would need solution for installation/usage of software (that can be used only on linux/ubuntu), regardless of details***, the current problem is basically related to single files only: I have two files, both in IMG extension. Don't know how to open them because Deamon Tools doesn't handle IMG. The problem is that filesystem in one of them is "Linux" and filesystem in another is "142". The error I am getting when I try to open them is:
"File with harddrive/disc snapshot is corrupted."
But this is most likely because they are supposted to be used in linux environment, hence such question.
*** when i said "details" I was referring to basically anything: type of software, size, purpose, whether or not it needs network connection, whether or not it contains logging in (username password, etc) requirement, etc.
The following solution for current situation (quoted error above) works only partially:
http://www.sysprobs.com/simple-tip-h...thout-software
I am able to open/run/mount IMG if I do what is described on this link (im basically opening iso in this case - see the website) but when opening the virtual drive, the following error message proves that the file can be used in linux/ubuntu only:
"Windows cannot access that drive. Drive could be corrupted. Make sure the drive is in condition that can be recognized by Windows. If drive isn't formatted then format it before usage."
Would need detailed instructions, for total beginner, who has never used linux/ubuntu, what to do in such case: how to use in win8 files/software that are supposted to be used in linux/ubuntu. Also answer on how to open IMG would be highly appreciated.
Kindest regards and thank you a million in advance.
The local provider has given us a fixed IP so we can have a web server for the car club's domain.
I will be using a Dell 2400 desktop computer with a 1.8 GHz Pentium 4 processor, 1 GB RAM, 40 GB hard drive and a DVD drive.
I want to use command line, not GUI and FTP the club's car pictures from my home.
My only Linux experience was sparse use of Red Hat 2.05 which is now 15 years old and not secure.
If the structure and folders are the same, Can I use CentOS 5.11 or 6.6
Thank you,
