What Is LVM (Logical Volume Manager)?- LVM is a storage manager that allows you to create a single or multiple logical storage volumes across multiple physical disks or partitions. There are 3 basic concepts used by LVM: PV (Physical Volume) - Represents a single physical hard disk, or a ...
fixed-size units of space. In particular, an extent is the smallest amount of space that can be allocated by LVM in Linux. All LVs in a VG are of the same size. LVM maintains a mapping between all logical and physical extents. This mapping is merely the LV, which can be expanded by...
GRUB Legacy (GRUB 1). This deprecated version of GRUB is still found on some olderLinux distributions. GRUB 2. This GRUB version supports new PC architectures (such asARM) andfilesystems(such asReiserFS),RAIDenvironments, and LVM. Most of the current distributions use GRUB 2. For example, ...
We are currently using LVM to manage our disk space. When using fdisk to create a partition, both types work with LVM, i.e. 83 (Linux) or 8e (Linux LVM). What are the advantages of using one over the other? Environment Red Hat Enterprise Linux 4 ...

To setup LVM, we first need an overview of all drives connected to the machine. We can list them usinglsblk: sudo lsblk The output looks something like this: As you can see in the “type” column, we have one disk attached to the server a size of 400 GB and a few partitions. The...
According to the Linux manpages you can add raw disks as well as partitions to a volume group. In other documentation (RedHat, CentOS or openSUSE), all examples refer to adding partitions to the VG instead of raw disks. What is common (best) practice? linux lvm storage Share Improve this...
The directory mounted for each device is the 3rd argument in the output above. So for device /dev/sda1 would be /boot. The other devices are making use of LVM (Logical Volume Management) and would need to be further queried to know which actual device is being used by LVM. Share Im...
Update each LVM resource withtrace_ra=1: Raw # pcs resource update <resource id> trace_ra=1 NOTE: This is only recognized inpcs-0.9.157-1.el7and later. If you have an earlier version ofpcs, add the--forceoption. Check in/var/lib/heartbeat/trace_ra/*/for these logs to make sure...
Make it easier to support backups of mounted file system snapshots (LVM, ZFS, etc) without fudging paths and/or complicated chroot set ups Explanation While Restic supports relative path(s), it always stores the associated absolute path(s) to uniquely identify the backup snapshot for resolving...
