The restorefile argument instructs the pvcreate command to make the new physical volume compatible with the old one on the volume group, ensuring that the new metadata will not be placed where the old physical volume contained data. The pvcreate command overwrites only the LVM metadata areas and...
strict allocation policy meant that "Mirrors of a logical extent cannotshare the same physical volume." from man.From the below info, i have 2 pv to this vg. How can i verify that its not the same pv?# vgdisplay vg00--- Volume groups ---VG Name /dev/vg00VG Write Ac...

Each Oracle ASM extent consists of one or more allocation units on a specific disk. Note: An Oracle ASM extent is different from the extent used to store data in a segment. Oracle ASM Allocation Units An allocation unit is the fundamental unit of allocation within a disk group. An ...
The change makes it so that the returned parallel areas list contains one "super" segment (seg_pvs) with a list of all the PVs from every actual segment in the given LV and covering the entire logical extent range. This change allows RAID conversions to function properly when there are ...
Physical extent 0 to 47873:Logical volume /dev/vg_os/lv_osLogical extents 0 to 47873 Using vgdisplay command Here we will have all physical devices used per Volume Group, not per Logical Volume. So first we have the VG info, below we will find all LVs which corresponds t...
To assess the progress in physical rehabilitation in the case of physically impaired persons, clinicians rely on physical characteristics such as extent of elbow flexion, shoulder abduction, speed of motion and others. To determine such characteristics researchers have almost exclusively relied on ...
