--noudevrules
Disables udev rules. Nodes/symlinks will be created by libdevmapper itself (the old way). This
option is for debugging purposes, if udev does not work correctly.
--noudevsync
Disables udev synchronization. This is also for debugging purposes.
For more information on the dmsetup and its options, see the dmsetup(8) man page.
The LVM commands support the following options that support udev integration:
• --noudevrules: as for the dmsetup command, disables udev rules.
• --noudevsync: as for the dmsetup command, disables udev synchronization.
The lvm.conf file includes the following options that support udev integration:
• udev_rules: enables/disables udev_rules for all LVM2 commands globally.
• udev_sync: enables/disables udev synchronization for all LVM commands globally.
For more information on the lvm.conf file options, see the inline comments in the lvm.conf file.
