I have a file in the /etc/lvm/archive dir that seems to be the name of a vg.
I see:
Data {
seqno = 1933
format = "lvm2" # informational
status = ["RESIZEABLE", "READ", "WRITE"]
extent_size = 8192 # 4 Megabytes
max_lv = 0
max_pv = 0
metadata_copies = 0
physical_volumes {
pv0 {
device = "/dev/sdb1" # Hint only
status = ["ALLOCATABLE"]
flags = []
dev_size = 93755273216 # 43.6582 Terabytes
pe_start = 2048
pe_count = 11444735 # 43.6582 Terabytes
}
}
logical_volumes {
Home {
allocation_policy = "contiguous"
segment_count = 1
segment1 {
start_extent = 0
extent_count = 393216 # 1.5 Terabytes
type = "striped"
stripe_count = 1 # linear
stripes = [ "pv0", 0 ]
}
}
----
It appears that the start of the physical vol is at 2048 but not sure
what the units are --
Are those 2048 physical extents of size 8192 and is said to be
equivalent to 4MB? So the 8192 is a number of 512 byte sectors
(even though they underlying disk is 4K with 512e)?
At the start of the physical volume at 2048 should I see the logical
volume 'Home' as it starts at extent '0'?
So shouldn't I see the start of the Home partition 8MB in from the
front? Or is there something else before physical volumns? Does
first logical volume start at pe_start?
I.e. I'm assuming I have something wrong, because I'm not seeing anything
looking like the beginning of a file system at that location...
Thanks....
