Wow Awesome! Samjh aagya finally ❣
This has been a very good warm up for disk management. If you can simulate some real time disk crash issue, recovering it, fixing bad blocks, etc..it would be super.
Thanks for your efforts

Nice one sirji At about 44:33 duration of this video one guy admin anil asked how to mount ntfs(new technology file system) and u answered about nfs(network file system) instead of ntfs. In pure fedora (not sure about rhel/centos whether ntfs-3g n fuse packages are available in repository or in installation DVD iso images or need googling to download these packages)ntfs-3g n fuse packages are already installed. We can mount ntfs drive in d following ways:- mount -t ntfs-3g /dev/sda1 /mnt/winC-drive or ntfs-3g /dev/sda1 /mnt/winC-drive

Red Hat recommends to create a single partition that covers the whole disk to label it as an LVM physical volume. This way we can achieve Administrative convenience. It is easier to keep track of the hardware in a system if each real disk only appears once. This becomes particularly true if a disk fails. In addition, multiple physical volumes on a single disk may cause a kernel warning about unknown partition types at boot.
@NehraClasses

Yes, you're right. In live entertainment we should only create one partition on a single disk to create the physical volumes. But instead of copying this stuff from tldp.org you should have shared your own thoughts and experiences. Thanks
Awesome session
