Peter Rajnoha	2fc126b00d	filter-usable: move check for pv_min_size from filter-partitioned to filter-usable and use new 'udev' external device info source for this check ... The filter-partitioned code should contain only checks in "partition" domain. The check for pv_min_size should actually be a part of filter-usable. If the device size is less than pv_min_size, such device is not usable as a PV so this check clearly belongs here logically. With udev external info source, we can get device size via libudev's sysfs reading interface and we can avoid opening the device this way effectively.	2015-01-30 13:01:12 +01:00
Alasdair G Kergon	80bcdb93ff	filters: check for mpath before opening devs ... Split out the partitioned device filter that needs to open the device and move the multipath filter in front of it. When a device is multipathed, sending I/O to the underlying paths may cause problems, the most obvious being I/O errors visible to lvm if a path is down. Revert the incorrect <backtrace> messages added when a device doesn't pass a filter. Log each filter initialisation to show sequence. Avoid duplicate 'Using $device' debug messages.	2013-08-13 23:26:58 +01:00
