Peter Rajnoha	b8779e706e	configure: check for udev_device_get_is_initialized is available ... The udev_device_get_is_initialized is available since libudev version 165. Older versions are still used somewhere (e.g. RHEL6). So better check for this fn and use it only if it's available.	2015-11-11 15:15:50 +01:00
Peter Rajnoha	f82e0210b7	dev-ext: issue error if external_device_info_source=udev and udev db record incomplete ... Udev db records are marked as not initialized (incomplete) on timeout. Issue an error message whenever LVM finds such records so users are aware that something's going wrong with udev db. This is important in case we use devices/external_device_info_source="udev" where udev database records are used to do various filtering decisions. For example: udev log of timed out worker: Nov 11 13:02:25 raw.virt systemd-udevd[607]: seq 1997 '/devices/virtual/block/dm-2' is taking a long time Nov 11 13:04:25 raw.virt systemd-udevd[607]: seq 1997 '/devices/virtual/block/dm-2' killed Nov 11 13:04:25 raw.virt systemd-udevd[607]: worker [11221] terminated by signal 9 (Killed) Nov 11 13:04:25 raw.virt systemd-udevd[607]: worker [11221] failed while handling '/devices/virtual/block/dm-2' ... LVM also issues error message visibly if incomplete udev db record is found, devices/external_device_info_source="udev" is set: $ pvs Udev database has incomplete information about device /dev/dm-2. Failed to get external handle for device /dev/dm-2 [udev]. ...	2015-11-11 13:14:07 +01:00
