Subject: [PATCH] lvm_scan.sh: use -K when calling lvchange
|
|
|
1755ca |
|
|
|
1755ca |
The --ignoreactivationskip/-K switch was added to LVM2 in 2.02.99
|
|
|
1755ca |
(July 2013) and is used to control the activation of volumes with
|
|
|
1755ca |
the activation skip flag set: without -K these volumes will be
|
|
|
1755ca |
ignored when 'lvchange -ay $LV' is issued.
|
|
|
1755ca |
|
|
|
1755ca |
This prevents an LVM2 thin-privisioned snapshot from being used
|
|
|
1755ca |
as the root device when booting with rd.lvm.lv=vg/lv since the
|
|
|
1755ca |
activation skip flag is set for these snapshots by default (the
|
|
|
1755ca |
legacy non-thinp snapshots do not set this flag and can already
|
|
|
1755ca |
be activated and used as a root device by specifying appropriate
|
|
|
1755ca |
values for rd.lvm.lv).
|
|
|
1755ca |
|
|
|
1755ca |
This is only used in the rd.lvm.lv case since in that situation
|
|
|
1755ca |
we are activating one or more named LVs specified by the user:
|
|
|
1755ca |
the flag is not given when calling 'vgchange' since this may
|
|
|
1755ca |
cause many unwanted volumes to be activated during early user
|
|
|
1755ca |
space. Users wishing to use a specific snapshot volume should
|
|
|
1755ca |
specify it with 'rd.lvm.lv'.
