metadata: format_text: also export historical LVs
Also export historical LVs when exporting LVM2 metadata.
This is list of all historical LVs listed in
"historical_logical_volumes" metadata section with all
the properties exported for each historical LV.
For example, we have this thin snapshot sequence:
lvol1 --> lvol2 --> lvol3
\
--> lvol4
We end up with these metadata:
logical_volume {
...
(lvol1, lvol3 and lvol4 listed here as usual - no change here)
...
}
historical_logical_volumes {
lvol2 {
id = "S0Dw1U-v5sF-LwAb-W9SI-pNOF-Madd-5dxSv5"
creation_time = 1456919613 # 2016-03-02 12:53:33 +0100
removal_time = 1456919620 # 2016-03-02 12:53:40 +0100
origin = "lvol1"
descendants = ["lvol3", "lvol4"]
}
}
By removing lvol1 further, we end up with:
historical_logical_volumes {
lvol2 {
id = "S0Dw1U-v5sF-LwAb-W9SI-pNOF-Madd-5dxSv5"
creation_time = 1456919613 # 2016-03-02 12:53:33 +0100
removal_time = 1456919620 # 2016-03-02 12:53:40 +0100
origin = "-lvol1"
descendants = ["lvol3", "lvol4"]
}
lvol1 {
id = "me0mes-aYnK-nRfT-vNlV-UiR1-GP7r-ojbROr"
creation_time = 1456919608 # 2016-03-02 12:53:28 +0100
removal_time = 1456919767 # 2016-03-02 12:56:07 +0100
}
}
