Also add -k/--setactivationskip y/n and -K/--ignoreactivationskip
options to lvcreate.
The --setactivationskip y sets the flag in metadata for an LV to
skip the LV during activation. Also, the newly created LV is not
activated.
Thin snapsots have this flag set automatically if not specified
directly by the --setactivationskip y/n option.
The --ignoreactivationskip overrides the activation skip flag set
in metadata for an LV (just for the run of the command - the flag
is not changed in metadata!)
A few examples for the lvcreate with the new options:
(non-thin snap LV => skip flag not set in MDA + LV activated)
raw/~ $ lvcreate -l1 vg
Logical volume "lvol0" created
raw/~ $ lvs -o lv_name,attr vg/lvol0
LV Attr
lvol0 -wi-a----
(non-thin snap LV + -ky => skip flag set in MDA + LV not activated)
raw/~ $ lvcreate -l1 -ky vg
Logical volume "lvol1" created
raw/~ $ lvs -o lv_name,attr vg/lvol1
LV Attr
lvol1 -wi------
(non-thin snap LV + -ky + -K => skip flag set in MDA + LV activated)
raw/~ $ lvcreate -l1 -ky -K vg
Logical volume "lvol2" created
raw/~ $ lvs -o lv_name,attr vg/lvol2
LV Attr
lvol2 -wi-a----
(thin snap LV => skip flag set in MDA (default behaviour) + LV not activated)
raw/~ $ lvcreate -L100M -T vg/pool -V 1T -n thin_lv
Logical volume "thin_lv" created
raw/~ $ lvcreate -s vg/thin_lv -n thin_snap
Logical volume "thin_snap" created
