[Install] LVM configuration in Proxmox 7

[jbe-dw]

Hello,

I've reinstalled a 2 node cluster where we use iSCSI storage. We apply a filter to avoid host loading guest LVM. On these two servers I found the following snippet, preventing our configuration:

devices {
     # added by pve-manager to avoid scanning ZFS zvols
     global_filter=["r|/dev/zd.*|"]
}

Is there any option to prevent these lines to be appended to /etc/lvm/lvm.conf ?

I guess it is added at installation because these lines are not apended since last reboot this morning.

Regards

Why would that line prevent anything? You normally control stuff by the "ordinary" filter.

The `filter` directive prevents manipulating disks from the lvm cli (Limit the block devices that are used by LVM commands, as per config file comments), while global_filter totally ignore disks matched by the filter (Because devices/filter may be overridden from the command line, it is not suitable for system-wide device filtering, e.g. udev.)
