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, ...
Shrink an Existing LVM Partition When shrinking your LVM partition, it’s important to do so in the correct order – the filesystem must be resized before the logical volume, otherwise you lose data or even break the whole filesystem. Ext4 requires to be unmounted while shrinking. We can un...
Sys admins can use the current version of LVM (2.03.21as of 2023) and the device mapper driver in the Linuxkernelframework (2.6 kernel) to designate existing storage devices (hard disks) as physical volumes and place them into volume groups. The combined storage space that is created can t...
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 ...
What are the advantages and disadvantages of using partitioning on LUNs, either directly or with LVM in between? What should be taken into consideration in terms of administration, performance, and resilience in this context? Is it supported if we create Physical Volumes directly on disks, instead...
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...
A customer was using theLVM_SORTITEMSmessage to sort the items in a classic Win32 ListView control in response to the user checking a box called “Show sorted by date”. That part worked great. They ran into trouble when the user unchecked the box: What is the message for telling th...
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...
This issue is compounded further when absolute paths change, such as cases involving removable media, platform-dependent absolute paths (i.e. Unix VFS & Windows Drive Letters) or backing up filesystem snapshots with VSS, LVM, BTRFS or ZFS. ...
