Below is a summary of the pros and cons of each of the storage drivers tested: Loop-LVM XFS Pros; No configuration required; Decent performance at small base sizes. If by any chance you are appearing for an interview for a position if Linux Administrator then the most common question which is asked is what is the difference between RHEL5 and RHEL6 ? Virtualization: In RHEL 6 KVM (Kernel based Virtual Machine) was used as a hypervisor but in the earlier releases of RHEL XEN was used as a hypervisor. For example to show the diff from snapshot 71 to 72 only for file /etc/zypp/zypp. Other interesting properties of XFS are guaranteed rate input/output (I/O—through bandwidth reservation for file system users) and direct I/O, where data is copied directly between the disk and the user space buffer (rather than being staged through multiple buffers). I plan to install CentOS 7 on a ESXi hypervisor with hardware RAID and the Vmware Essentials package + Veeam backup for vmware. File systems are generally utilized in order for handling how the information is kept soon after any program no longer is utilizing it, how accessibility to the information is managed, what other information (metadata) is linked to the data itself, etc. As the partition came close to being full, one could expand an xfs file system, but if one could not, performance and data recovery suffered if there was an unscheduled shutdown. correct partition size and file system type: ext4) will result in failing the labl checking program and forcing a. UX design or user experience design, is the process by which a pain point or user need is identified.
