similar to: /boot on a separate partition?

Is there a document with instructions for this? I've had smartd warnings that a hard disk in my server is sick, so I am installing a new drive (in addition to the old). I was thinking of copying the old root partition with sudo cp -a -P /* /mnt/hd (after mounting the prospective new root partition). Then I'd have to modify the new /etc/fstab . Is that a sensible approach? -- Timothy

Different distros have different defaults. There's no actual right or wrong here. Pretty much anything you can think of can be made to work.

I am planning to increase the disk space on my desktop system. It is running CentOS 5.9 w/XEN. I have two 160Gig 2.5" laptop (2.5") SATA drives in two slots of a 4-slot hot swap bay configured like this: Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End

I would like to upgrade a CentOS-6.5 home server to CentOS-7 on a new partition. What is the simplest way to achieve this? I would like to be able to boot into either version of CentOS until I am sure the new version is running OK. Incidentally, I think most people today must have enough space on their hard drive to install a new OS on a new partition - it is surprising that this option never

Well, there's best and worst case scenarios. Best case for file-backed VMs is

Is there a standard way of copying a working system from one machine to another with different partitions? I have two CentOS-5.6 machines, say A and B, and I thought I would copy / on sdb10 on machine A to an unused partition sda7 on machine B with rsync. I made the appropriate changes to /etc/fstab and grub.conf , as well as /etc/sysconfig/network-scripts , but found that there were innumerable

Here's the situation. I have a dual boot machine - originally had Red Hat and Windows 2000 Pro. The NTFS partition never did seem to 'get along' with the Adaptec 2400A caching RAID controller. Linux always seemed to like the I2O drivers. I went from RH Enterprise to now running Centos 5.5. Works great! I really don't want the 200 gigs worth of NTFS. Can't I just run

I have a Centos 7 install using EXT4 on LVM. Its running as a VM inside KVM. Issue I have run into is that fstrim does not work due to the LVM. Without fstrim snapshots have gotten huge. Is there a way convert it from LVM to non-LVM without a complete reinstall?

OK, I wanted to replace the 500G disks in a Dell T20 server with new 2TB disks. The machine has 4 SATA ports, one used for the optical disk and three for the hard drives. It is set up with /dev/sda and /dev/sdb with each three partitions: 1 -- VFAT (for EFI) 2 -- ext4 (for /boot) 3 -- LVM /dev/sda2 and /dev/sdb2 are a mirror raid (/dev/md0) /dev/sda3 and /dev/sdb3 are a mirror raid

I recently acquired a Fujitsu Lifebook 1610. Unfortunately, the machine was missing a lot of the stuff that would've come with it brand new, mainly the usb cdrom drive. Currently, I'm running Fedora on it, and I installed it using a usb flash drive with the help of a program called unetbootin(Probably not spelled right). to load the ISO onto the USB drive. I've successfully used

What is the best way to install CentOS 6? Is there an upgrade facility from CentOS-5.6? If so, how does this compare with a clean installation? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

I am trying to run my old CentOS4.8 (32-bit) system as a guest system under CentOS5.4xen (64-bit). I followed the instructions in Appendix A of the xen user manual (/usr/share/doc/xen-3.0.3/pdf/user.pdf) and created a 'disk image' (actually a 10gig LVM logical volume: sauron.deepsoft.com% sudo fdisk -l /dev/mapper/sauron-c4guest Disk /dev/mapper/sauron-c4guest: 10.7 GB, 10737418240
