Use fdisk or parted to create a new partition. parted is generally preferred for modern systems as it handles larger disks better: # parted /dev/sdd (parted) mklabel gpt (parted) mkpart primary 0% 100% (parted) quit Or with fdisk for MBR-based systems: # fdisk /dev/sdd Then: Press n to create a new partition Press p for…
Package Installation Install the required packages: dnf install nfs-utils nfs-utils includes both server and client tools. The separate rpcbind package is no longer needed on modern systems — it’s handled as a dependency and runs as part of the NFS service. Configure /etc/exports Edit /etc/exports to define which directories clients can mount and with what…
This post describes Xen DomU setup procedures from the early 2010s. While Xen remains critical infrastructure for cloud providers like AWS EC2 and Citrix Hypervisor, it’s rarely deployed for new on-premises virtualization projects. For modern Linux virtualization, consider: KVM/QEMU: The default hypervisor in most Linux distributions, better community support, and tighter kernel integration Proxmox VE…
tmpfs delivers exceptional I/O performance since it lives entirely in RAM. Exporting it via NFS can be useful for temporary caches, build artifacts, or high-speed data sharing between systems on a trusted network. The catch: NFS needs additional configuration to export pseudo-filesystems like /dev/shm. Without the right settings, you’ll hit access denied errors or fsid…
On Fedora/RHEL-based systems: dnf install ecryptfs-utils On Debian/Ubuntu: apt-get install ecryptfs-utils Load the kernel module modprobe ecryptfs To ensure the module loads automatically on boot, add it to /etc/modules-load.d/: echo “ecryptfs” | sudo tee /etc/modules-load.d/ecryptfs.conf Create directories You’ll need two directories: one for encrypted storage (.private) and one as the mount point (private). The .private…
sshfs is the standard tool for mounting remote filesystems over SSH. It’s available in most distribution repositories. Debian/Ubuntu: sudo apt install sshfs RHEL/CentOS/Fedora: sudo dnf install sshfs Alpine: apk add sshfs On some systems you may need to ensure the fuse kernel module is loaded: sudo modprobe fuse Basic Mount Mount a remote directory to…
ISO images are sector-by-sector copies of optical media stored as binary files. They’re useful for archiving DVDs or creating portable copies without keeping physical disks around. On Linux, several tools can accomplish this—dd is the simplest, but modern alternatives offer better features. Using dd to Create an ISO Image The most straightforward approach uses dd:…
Mounting an ISO on Linux requires a loop device. Modern systems support this directly with mount: sudo mount -o loop /path/to/image.iso /mnt/mount-point Or use the -t iso9660 option for explicit filesystem specification: sudo mount -t iso9660 -o loop /path/to/image.iso /mnt/mount-point To unmount: sudo umount /mnt/mount-point For temporary mounts that don’t require persistence across reboots, consider…
