Peter Rajnoha	2f5ddfbade	udev: add support for "NOSCAN" flag ... Recognize DM_SUBSYSTEM_UDEV_FLAG0 which for LVM is the "LVM_NOSCAN" flag that causes the scanning to be skipped (mainly blkid) and also directs all the foreign rules to be skipped as well. Important thing here is that the "watch" udev rules is still set as well as the /dev/disk/by-id content created (which does not require any scanning to be done). Also, the flag is dropped on any subsequent event and scanning done...	2013-10-08 13:43:14 +02:00
Peter Rajnoha	e4c7236c07	udev: fix 3min udev timeout so that it is applied for all LVM volumes ... The timeout should be set before any volume skipping.	2013-09-27 15:37:16 +02:00
Peter Rajnoha	72a9d4f879	udev: override new udev default timeout of 30s to original 3min ... New versions of udev changed the default event timeout to 30s from original 3min. This causes problems with LVM processes that starve because of the IO load caused by some LVM actions (e.g. mirror/raid synchronization). Reinstate the 3min udev timeout for now until we optimize this in a way that even the 30s timeout is sufficient.	2013-09-11 12:47:38 +02:00
Peter Rajnoha	e6f8d86409	udev: udev rules cleanup ... Remove executable path detection in udev rules and use sbindir that is configured, but still provide the original functionality by means of 'configure --enable-udev-rule-exec-detection'. Normally, the exec path for the tools called in udev rules should not differ from the sbindir used, however, there are cases this is necessary. For example different environments could be assembled in a way that these path differ for some reason (distribution installer, initrd ...). This functionality is kept for compatibility only. Any environment moving the binaries around and using different paths should be fixed eventually!	2012-06-27 12:11:56 +02:00
