View 1 Replieshow can I clone my installed ubuntu to a new harddisk? with 32bit ubuntu I have used:tar cvpzf -> create a tar file on my external nas system. after that I have done a restore tar xvpfz - worked with 32 bit.
Alternative I have mounted both disks and via another linux partition I have used:
cp -rvbdR /source/* /target
both methodes worked with ubuntu 32 bit. With 64 bit ubuntu I can NOT get it to work. error message after booting the clone: /var/lib/gdm/.ICEauthoriy ..
I can see that /source/var/lib/gdm has different rights as /target - will be part of the problem.
This did not happen with the 32 bit ubuntu - but why ?
I have machine that I used to VNC to on my network with Remote Desktop Viewer from my Fedora 12. When I first connected I checked the checkbox that I wanted to store the pw. Now the pw on the other machine has changed but Remote Desktop Viewer does not ask for a new password, it just gives me a black screen, like I am connected but I can't see anything. I'd like to know if anyone knows where this pw data is stored on the system so I can start fresh. I already tried uninstalling Remote Desktop Viewer and installing it again.

I have a 60GB hardisk, and try to install CENOS 5.5 HEL5.5 and Fedora13 on it. I partitioned the harddisk to 4 primary partitions like below:
Partition MountPoint Type
sda1 /boot ext3
sda2 VGRHEL LVM PV
sda3 VGCENT LVM PV
sda4 VGFEDORA LVM PV
I created 3 Volume Groups as you see up: VGRHEL, VGCENT, VGFEDORA; under every VG, i created 2 logical volumes ,just like below: VGRHEL=LVRHEL00(swap) + LVRHEL01(MountPoint: /) Below VG try to partition them the same as VGRHEL too. VGCENT=LVCEN00(swap) + LVCEN01(MountPoint: /) VGFEDORA=LVFEDORA00(swap) + LVFEDORA01(MountPoint: /)
I successed installed RHEL5.5 on VGRHEL, but when i try to use the same way to install CentOS 5.5, i got below error infromation: "Bootable Partitions cannot be on a logical volume" I don't why this happened, VGRHEL has logical volume too, but why i can install RHEL on it successfully.
I have a new Ultra 27 running debian and i cannot see the second internal harddisk any ideas what to do to rectify this.

I tried to format my harddisk (160 GB) with the following command
dd if=/dev/zero of=/dev/sda
After some 3 hours, following error came up:
dd: writing to '/dev/sda' : No space left on device
312581809+0 records in
312581808+0 records out
160041885696 bytes (160 GB) copied, 10708.3 s, 14.9 MB/s
For whatever reason /dev/sda3 (at /tydelik) does not mount itself (like all the other partitions) when the system reboots.
In YaST's expert partitioner it says that:
Quote:
An asterisk (*) after the mount point indicates a file system that is currently not mounted (for example, because it has the noauto option set in /etc/fstab).
Here is the /etc/fstab :
Quote:
I don't see a noauto option. Is it hiding somewhere?
Also, if I say the following then it seems that /dev/sda3 is ext2 and not ext3 (as YaST says).
Quote:
Firstly, how do I specify /dev/sda3 to be mounted by default (because I thought it would unless there is a noauto specified), and secondly, why is YaST not showing the same settings as when I say "mount" ?
As i said in title, we need to erase all datas from harddisk before distroy our old servers.
Quote:
dd if=/dev/zero of=/dev/hda bs=1M
Quote:
shred -fzuv -n 100 /dev/hda
1. Which is the best practice to erase data, dd or shred?
2. How can i execute these commands in running server, do i need to re-boot the servers as RESCUE mode using bootable cd?

I have an external hard drive with an xfs partition on it. It was using an external journal, but in re-installing Slackware I removed the partition holding the external journal, forgetting what it was at the time. I didn't touch the contents of the external hard drive, but now I can't mount it and the various xfs programs seem to demand that it be mounted in order for them to change anything.Anyone have any ideas on how to change an xfs partition from external log to internal? Failing that, how do I get the information off it?

I have a Western Digital My Book World Edition external harddisk with blue rings. I filled it up and now want to delete the data and start over. I'm set in my ways and have been accustom to reformatting harddisks periodically (sector maintainance, etc.) It's worked for me as I've luckily have not had a disk crash in 25 years.My webapp is not helping me with the reformat and neither is Western Digital tech support. I've heard that it was factory formatted with something called Linux ext3. Does this make sense? Has anyone had any experience with reformatting external harddisks being used as a NAS (home use).

While studying where all my (16 GB solid state) disk space is used with Disk Usage Analyzer I found that about a half gigabyte was under sys/devices/pci0000:00/pci0000:00:01.0. In fact it was taken up by two files resource2 and resource2_wc. Both files are dated today.
Can anyone enlighten me to what these subdirectories and files are? My desktop with conventional rotating hard drives do not have any space used under /sys/devices so I am guessing the subdirectories and files are related to the Solid State drive.

I would like to see the journal of a file-system (ex. ext4) in action. What i mean is that, without knowing what kind of fs is on a partition, i want to test if this fs supports or not journaling.
