Version 2.02.99 -
|
||||
===================================
|
||||
Refine lvm.conf and man page documentation for autoactivation feature.
|
||||
Add support for thin volumes in vgsplit.
|
||||
Also filter partitions on mpath components if multipath_component_detection=1.
|
||||
Add lvresize support for online thin pool metadata volume resize.

# first checked against the list. There are two scenarios in which
|

# the autoactivation option is used:
|
||||
#
|
||||
# - automatic activation of volumes based on incoming PVs. If all the
|
||||
# PVs making up a VG are present in the system, the autoactivation
|
||||
# is triggered. This requires lvmetad (global/use_lvmetad=1) and udev
|
||||
# to be running. In this case, "pvscan --cache -aay" is called
|
||||
# automatically without any user intervention while processing
|
||||
# udev events. Please, make sure you define auto_activation_list
|
||||
# properly so only the volumes you want and expect are autoactivated.
|
||||
#
|
||||
# - direct activation on command line with the autoactivation option.
|
||||
# In this case, the user calls "vgchange --activate ay/-a ay" or
|
||||
# "lvchange --activate ay/-a ay" directly.
|
||||
#
|
||||
# If the VG/LV being processed does not match the list, the VG/LV is not
|
||||
# activated. If auto_activation_volume_list is not set, then all volumes
|
||||
# are activated by default.
|
||||
#
|
||||
# N.B. The "activation/volume_list" is still honoured in all cases so even
|
||||
# if the VG/LV passes the auto_activation_volume_list, it still needs to
|
||||
# pass the volume_list for it to be activated in the end.
|
||||
#
|
||||
# "vgname" and "vgname/lvname" are matched exactly.
|
||||
# "@tag" matches any tag set in the LV or VG.
