# LVM setup on Storware Backup & Recovery Node for disk attachment backup mode {% hint style="info" %} **Note:** This is required for backup of virtual environments when using disk attachment mode, such as Nutanix backups. {% endhint %} Storware Backup & Recovery Node attaches VM disks that potentially are clones of its own (for example if Node deployed from the template) - you need to configure LVM on the Node so that it doesn't scan for LVM volumes where disks are being attached. 1. Set the following variables in `/etc/lvm/lvm.conf` in `devices` section - so that only system volumes are being detected by LVM daemon (in this example sda disk with 2 partitions - sda1 and sda2): ``` devices { filter = [ "a|^/dev/sda|", "a|^/dev/sda1|", "a|^/dev/sda2|", "r|.*|" ] global_filter = [ "a|^/dev/sda|", "a|^/dev/sda1|", "a|^/dev/sda2|", "r|.*|" ] } ``` 2. Check with `vgscan -vvv` that your OS volumes are still being detected: ``` Allocated VG vg_vprotect at 0x55914f19fac0. Importing logical volume vg_vprotect/lv_root. Importing logical volume vg_vprotect/lv_swap. ``` 3. Reboot: ``` reboot ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
