What is LVM metadata?

– LVM metadata contains configuration details of volume groups. – Metadata backups and archives are automatically created on every volume group and logical volume configuration change. – Backups are stored in /etc/lvm/backup.

Can a RAID 1 drive be replaced in a LVM mirror?

LVM lets you split volumes and re-sizing them easily. However, If a drive in the LVM mirror fails the after you replace it you have to rebuild the mirror manually. With RAID1 you have a little less flexibility but more redundancy. Also, if you replace a failed Raid1 drive the mirror rebuilds itself.

What is the purpose of mirroring in LVM?

LVM mirrors are for replication of a logical volume to a different physical volume. It’s essentially meant to “move the data to a different disk”. The mirror is then broken and the old location of the data freed for use; the existing data is utilized at the new location instead.

Which is better Linux LVM or RAID 1?

Problem is that according to what I found on the Internet, LVM is: Slower then RAID-1, at least in reading (as only single volume being used for reading). Non-reliable on power interrupts, and requires disk cache disabling for prevention of data loss.

What happens if a mirror is broken on a RAID server?

The mirror is then broken and the old location of the data freed for use; the existing data is utilized at the new location instead. RAID mirrors are for providing a safeguard against single-drive hardware failures.
