I am attempting to copy files from one server to an external USB drive on a second server. Both servers are running custom RedHat Linux, kernel 2.6. Both are setup as Check Point SecurePlatform (one is a log server and the other a management server). I am trying to archive files from one (HP DL380 G5) to the second (HP DL380 G6). I am not able to archive directly to the external usb drive when connected to the HP DL380 G5 (data gets corrupted and switches to read-only access). The external USB drive has no issues when connected to the HP DL380 G6 server, thus my reason for trying to copy the files across servers.
When I attempt to use scp to copy files between the server, I am prompted for the password. Once entered the debug shows the authentication is successful, but then no files are copied (see log below). I have tried searching for potential answers, but none have panned out. Unfortunately I can't yet post the actual scp debug log output as some of the text is viewed as a URL and not yet allowed for me. I have changed all the atsign symbols to '(a)' to avoid the URL inference.
Output log from scp attempt follows:
[Expert(a)server1]# scp -p -r -v /var/fromhere/* copyfile(a)server2:/media/disk/tohere/

I have a 160GB harddrive which I installed a F12, would like to upgrade to a bigger drive, but I hate to have to re-install everything.
Recommend a good disk copy utility? The utility should be able to not only copy files, but boot sector and everything. So I just need to make a copy, change my BIOS to boot from the new drive and run everything as before.

I have a Dell workstation, 2 HDD, HDD 1 setuped Red Hat 5.3 with LVM, and that HDD 2 is empty, not install RAID 1. And, I want to setup RAID 1 (hardware RAID)...but, have a problem. I don't want to lost data on HDD 1 when I setup raid, I try ghost or backup it, but when I restore, it error because LVM is setup on that.

I have a software RAID array using mdraid that consists of two 1.5TB drives that I use for storage, the array is mounted at /Storage. I am running out of space in the array so I ordered two more 1.5TB drives to create a 4 drive RAID 1+0 array which will be 3TB big. My question is how do I create the new array and not lose any data?
The drives and partitions are sdc1, sdd1, and soon to be sde1, sdf1. I currently have 4 RAID arrays (md0,md1,md2,md3). I think I can create the RAID 1+0 array with the two new drives, copy the data from my current array to the new one, remove the old array, then add the two original drives to the new array. But I wanted to ask on here first to make sure my data doesn't go poof.

Right now I have a 320GB system drive and 3TB data drive. I want to add two more 3TB drives and do a software RAID5 3x3TB. Is that possible without losing the data that is already on the data drive?Just want to make sure before I bought the 2 two drives. Not looking for instructions on how to do it,but if you want to include some that would be great too Just making sure it will work.

I've been using Excel from OpenOffice with moderate success for the last year. Now I've just tried to open a new spreadsheet and I'm suddenly getting a highly condensed view. The cells are about 1mm X 4mm. If I expand them by selecting and dragging, then try to copy data from another spreadsheet onto the new one, the data shrinks to the small scale -- unreadable.

I want to update syslinux to version 4.03 on my system, so I took a look at the SlackBuild.
I noticed that the SlackBuild rebuilds everything including the actual boot loader with 'make -j4', but there's a note in the docs directory (distrib.txt) that asks not to do that:
Quote:
For creators of Linux distributions:
Syslinux is a notoriously hard program to debug, since it runs outside of any operating system, and has a tendency to expose BIOS and hardware bugs on various systems. Therefore, I would appreciate if you would resist the temptation of recompiling the Syslinux bootloader itself (ldlinux.asm) if at all possible. If you do that, I will have to refer any bug reports I receive back to the respective distributor.
However, I have no such concerns about recompiling the installer programs, and in fact, with both libc 5 and libc 6 in common use in the Linux world today I understand if you wish to relink the Linux-based installer against your system version of libc. Therefore a special makefile targets "make installer" has been included with the Syslinux distribution, starting with version 1.42.
To rebuild the installer programs *only*, starting from a freshly untarred distribution copy of Syslinux, do:
make clean
make installer
If you want to remove all intermediate files, including the ones obtained from assembling ldlinux.asm and which are included in the distribution, do "make spotless".
I thought I'd report this in case it was unnoticed by Pat and the team. If not I apologize for wasting your time

just installed ubuntu couple of days back on my netbook. I am still a beginner, enjoying my adventure exploring ubuntu. I have another desktop which runs on XP. I am able to access XP shared folders through my netbook(linux). However, i wanted to copy files from XP infact folders using TERMINAL in my netbook, not copy and paste using my mouse. Are there any commands for it?

I'm a newbe with linux, thought it's a great OS but I'm nearly giving up. Nothing works like it should, to copy stupid files across you have to be some kind of wizz to do it.
I installed fresh copy of fedora 13, created folder on the desktop and connected via usb external hd.
Now, there is no way of coping files from my desktop to the USB drive as i get"error while coping to USB-Storage" The destination is read-only. Permissions - sure but there is nothing there sa tehy could not be determined.
Anyway, hoping someone can give me a light from the dark tunnel, so i don't have to go back to windows..

I am not a programmer so, with scripts I am cold.I need this.When I plug in USb external disk, a files and folders are automatically copied from one folder on fedora, to my USB disk. And if files or folder are already on USB disk, it skips copying. So it copies only new files and folders.

After latest samba updates from updates-testing (F11) I can't copy any file from the network via samba: when copy process reaches almost end of the file, error message appears 'Invalid argument'. Such error happens with any read attempt on a network file - the last ~5% of a file can not be read.

I had Fedora 7 and Windows-XP dual operating system. Few weeks ago, there was GRUB error. Now I want to install Fedora 14, but before it I want to back up all data in one external hard drive. I used Fedora 13 live-CD I could access all the drive formatted as NTFS, but I couldn't access /home and the drive formatted (ext2) and owned by the user-name.
Please, inform if there is any idea to copy my files that remains in the home folder. (I can see them but copying is prevented)

has anyone used some software tool for copying a file from one location to another (I mean local files - for example from one folder to another), which prompts if you already have this file, or a similar one...I'm going to use it for my file archive ... mostly for my MP3For example, I might have the folder /home/user/MP3/Heavy Metal/Old/Downloaded/Metallicabut have forgotten that I already have Metallica in this folder and now I want to copy my new music collection to my archive folder which contains for example this folder:MP3/Rock/MetAllicA-Full-DiscographyI need copy files software which will tell me:"You already have folder with similar name to 'MetAllicA-Full-Discography' called 'Metallica', do you want to skip this folder, or copy it to location 'MP3/Heavy Metal/Old/Downloaded/'?"This way I will reduce the file redundancy in my file archive, or at least will keep similar items close to each other ..

So I've pulled two hard drives out of my busted windows xp system (dead mb) and I'm trying to get some data off of them. The drives are in raid 0, so my friend told me that I might be able to do something if I use linux. Some late night searching on the internet directed me to a few resources, one of which was this forum. I've tried 2 methods, neither of which have worked.
1. mdadm
ubuntu@ubuntu:~$ sudo mdadm --detail /dev/sdb
mdadm: /dev/sdb does not appear to be an md device
2. dmraid
ubuntu@ubuntu:~$ sudo dmraid -s
/dev/sdb: "sil" and "hpt45x" formats discovered (using hpt45x)!
ERROR: sil: wrong # of devices in RAID set "sil_agafdhcebccj" [1/2] on /dev/sda
ERROR: removing inconsistent RAID set "sil_agafdhcebccj"
[code]....
I've got some files for work that I'd really like to get off there. I've played with unix a bit in college and I've ran ubuntu before, but usually using the GUI, so a lot of this stuff is over my head. But from what I gather, my system thinks that one of the drives isn't a raid drive?

my question is quite simple and at the same time should even sound weird for people that is used to use raids... but here we go! I have got 2 hard disks that do match in space. I'd like to use mdadm to create a raid 1, the mirror one. Since I don't want to format / erase / delete what's in my primary hard disk (/dev/sda, 3 partitions), how can I replicate its content into /dev/sdb and mirror it with the raid tool? Does something like this work?
- install madam
- fdisk /dev/sdb and replicate sda's partitions (using as filesystem "fd");
- sudo mdadm --create --verbose /dev/md0 --level=mirror --raid-devices=2 /dev/sda1 /dev/sdb1
- sudo mdadm --create --verbose /dev/md1 --level=mirror --raid-devices=2 /dev/sda2 /dev/sdb2
sudo mdadm --create --verbose /dev/md2 --level=mirror --raid-devices=2 /dev/sda3 /dev/sdb3
Do you have any page to point, with the right documentation to achieve a replication of the hard disk without a format of the source disk?

I currently have a 1.5TB sata drive connected to my system, with data already on it. In the next few days I am planning to use mdadm to create a raid5 array with another 2 1.5TB drives along with the one I already have. Is it possible to create the raid without losing the data on my current hard drive? Obviously it will be backed up before hand just in case, but it would be nice not to have to restore nearly a TB of data after raid'ing the drives.

My friend has a DELL DIMENSION 9150 computer with 2 harddisk (250 GB each) in RAID 0 (fake raid) with Windows XP installed. There are a lot of documents and pictures installed - and no backup ever done! I have found some pages regarding recovery data from RAID 0 () but My friend have bought 2 new harddisks(WESTERN DIGITAL 2500AAJS) which is almost the same as the ones inside.
My plan:
1. copy each harddisk
2. replace original HDDs with my copies
3. try to recover
4. change RAID 0 to normal HDD in BIOS
5. reinstall Windows XP
I have some LINUX distros (DSL, SystemRescCD, UltimateBootCD on Live-CD and UBUNTU installed on one other computer) which I can use. I read about "dmraid" and then try to mounting the RAID in a UBUNTU live-CD version...

I'd like to set up RAID for my data partition.
My data are in /dev/sda5 (ext3).
There's an empty partition /dev/sdb5 (ext3).
I want /dev/sdb5 to be a mirror image of /dev/sda5, the command to invoke should be :
mdadm --create /dev/md0 --level=mirror --raid-devices=2 /dev/sda5 /dev/sdb5
My question is : how to ensure that the synchronization is done by copying data to the empty space and not the converse ?

I've tried to install Fedora 11, both 32 and 64 on my main machine.It could not install as it stops on the first install window. I've already filed a bug but really haven't seen any feed back yet.The bug has something to do with Anaconda and the Raid array but I really can't tell.
I have an Intel Board (see signature). I am running intel raid software under W7 currently.It works fine. But, I'm wondering, when I attempt to install F!!, is my current raid set-up causing problems? Do I need to get rid of the intel raid software and use a Fedor/Linux raid program to manage the raid array??

I am trying to create a RAID data drive for my system but I am having setting it up since I am a total linux noob.
The system has 3 physical HDD-s:
1. 320 GB (has functional Ubuntu 9.10 installation) attached to a PCI SATA card
2. 2TB on motherboard
3. 2TB on PCI SATA card
I want to create a software RAID1 of disks 2 and 3. So far I have used the Palimpsest Disk Utility:
- Created a GUID Partition table on both disks (2, 3)
- Used File -> New -> Software Array, made sure both my drives were included
- Once Palimpsest listed the RAID Drive as a Software RAID Array, I told it to create Ext3 filesystem on it
Well.. at least thats what I thought I did. At this point I have been able to mount the RAID drive and put files on it. However when I look at its information in Palimpsest, I am told that the drive is not partitioned. Both RAId components /dev/sda1 and /dev/sdc1 are reported to be in Sync, but the RAID Drive's own state is 'Running, Resyncing @ 45%' (and lowly growing).
My questions are: Is this a normal setup or did I do something incorrectly? Why is the drive reporting to have no partition? And howcome I can use it if it does not have a partition? I have found the command line based configurations to be a tad too confusing to follow, so I have tried to stick to graphical tools - is this a hopeless cause in Ubuntu or is it possible to achieve what I want to do without command line? I will list some info on my disks below - perhaps this offers more insight to those of you more familiar with Linux.
Code:
mindgamer@mind-server:~$ sudo lshw -C disk
[sudo] password for mindgamer:
*-disk:0
description: ATA Disk
product: WDC WD3200BEVT-0
vendor: Western Digital

I was using a Buffalo LinkStation Duo to store pictures and the OS in the unit failed. As far as I know, the data on the two 1 TB drives is fine, and since Buffalo uses a Linux kernel in their LinkStation and the format is xfs, it should be possible to get the data off if I can mount one of the drives on a Linux box. I've put one of the drives into an external USB enclosure and attached it to my Linux system, but I cannot get the drive to mount, probably because it is one element of a Raid 1 array.
Most of what I can find on the Web concerns setting up a new Raid array, not creating an array around a drive that already contains data. I have installed mdadm, and I'm running Mint Linux release 9 (Isadora) on an Intel box. When I run mdadm -D /dev/sdb or sdb6, the device and the partition where the data is located, it reports that the device does not appear to be an md device. I'm not sure what that means. Any help would be greatly appreciated, as I've got around 13,000 photos on these disks that have no backup (I figured what could go wrong with mirrored copies?).
