Forext2/ext3/ext4 basedfile systems use the commandresize2fs /dev/centos/var. Forxfs-basedfile systems use the commandxfs_growfs /dev/centos/var. For Reiserfs file systems use the commandresize_reiserfs -f /dev/vg01/lvol1. What is the physical extent of LVM? In LVM, the physical extent...
(The latter form must be preceded by '--' to terminate command line option processing before reaching this argument.) There are also various reserved names that are used internally by lvm that can not be used as LV or VG names. A VG cannot be called anything that exists in /dev/ at ...
raid4 is a form of striping that uses an extra, first device dedicated to storing parity blocks. The LV data remains available if one device fails. The parity is used to recalculate data that is lost from a single device. The minimum number of devices required is 3. lvcreate --type raid...

Solving the 'disk full' problem in LVM Now that you have a directory mounted, let's simulate the famous initial disk full problem. First, consume your 50 MiB of space. You canuse the dd commandfor this purpose. dd if=/dev/urandom of=/mnt/var_log/large_file bs=1MiB count=50 ...
Now that you are familiar with some of the terminology and structures LVM uses, you can explore some common ways to use LVM. You’ll start with a procedure that will use two physical disks to form four logical volumes. Marking the Physical Devices as Physical Volumes ...
links in the chain have been removed. A reference to the historical LV 'lvol1' in VG 'vg00' would be 'vg00/\-lvol1' or just '-lvol1' if the VG is already set. (The latter form must be preceded by '--' to terminate command line option processing before reaching this argument...

The machine reset is effectively a severe form of "deactivating" LVs before they can be activated on other hosts. The reset is considered a better alternative than having LVs used by multiple hosts at once, which could easily damage or destroy their content. In the future, the lvmlockctl ...
