Linux volume manager (LVM)

[%=Vertica.DBMS_SHORT%] supports Linux Volume Manager (LVM) on all supported operating systems.

Vertica 25.2.x supports Linux Volume Manager (LVM) on all supported operating systems.

LVM version supported

Vertica supports LVM version 2.02.66 or later and includes device-mapper version 1.02.48 or later.

LVM configuration notes

In configuring LVM:

  • When you create logical volumes with the lvcreate command, use the readahead option to set the read ahead sector count to greater than 2048 KB.

  • You can use the default settings for all other LVM options.

LVM restrictions

The following limitations apply to LVM support:

  • You cannot have physical drives shared across several nodes.

  • Vertica supports linear logical volumes only. It does not support striped or mirrored logical volumes.

  • The database supports extending logical volumes (lvextend) but not reducing the size of a logical volume.

  • We recommend frequent backups.

  • The database does not support LVM backup and restore, such as LVM snapshot and merge. Use the Vertica backup utility vbr.

  • The database does not support LVM space reclamation because space reclamation is duplicated when reducing the size of a logical volume.

  • The database does not support LVM migration. Use Copy operations.

  • The database does not support LVM high availability. Use the high availability capabilities of the database.

  • The database does not support LVM RAID. Configure RAID at the disk controller level.
