[linux-lvm] About storing Lvm configuration

[Vahric MUHTARYAN]

Okey , I checked it .. 

Do you talk about this ?! 

/* disk stored PV, VG, LV and PE size and offset information */
typedef struct {
        uint32_t base;
        uint32_t size;
} lvm_disk_data_t;


İt's look like MBR , because MBR write information 0 sector and I know that
MBR have a backup of information end of the partition or disk !? 

Does LVM take a backup information of begining of each PV ?! 

Thanks _!

At the beginnng of each PV (see lvm.h for details).

Yes, you need to move all disks of a VG to the other computer.
