I'm trying to move an LV from one VG on 1 PV to another VG on another PV,
but it doesn't seem to like my syntax. Isn't it: " -n LV FROMPV TOPV"
> sudo pvmove -n Win /dev/sda1 /dev/sdc1
Physical Volume "/dev/sdc1" not found in Volume Group "HnS"
Pertinent details:
> lvs #(From volume in HnS)
LV VG Attr LSize
Sys HnS -wc-a---- 96.00g
> pvs #(from VG HnS on PV /dev/sda1, destination PV = /dev/sdc1
PV VG Fmt Attr PSize PFree
/dev/sda1 HnS lvm2 a-- 21.83t 10.20t
/dev/sdc1 Data lvm2 a-- 43.66t 39.46t
----
Before I got to that point:
> sudo pvmove -n Win /dev/sda1 /dev/sdc1
Required device-mapper target(s) not detected in your kernel
(for some reason kernel module isn't auto-loaded??? (the minor bug..))
So:
> sudo modprobe dm-mirror
-- Don't know if any other modules are needed? I have:
> ls -d /sys/module/dm*
/sys/module/dm_bufio/ /sys/module/dm_mirror/ /sys/module/dm_region_hash/
/sys/module/dm_log/ /sys/module/dm_mod/ /sys/module/dm_snapshot/

Available (not loaded):

dm-bio-prison dm-raid dm-zero
dm-persistent-data dm-thin-pool
I'm assuming I only needed the dm-mirror so it could do the
mirroring? What syntax should I be using?
Thanks!

thanks...urk....ok.. long way around...(want to move a house from one
city to another,
but first must merge cities, then logical-house-move from one side of
the city
to the other; then un-annex the old-part of the city)...;-/
Um... trying the merge, I get:
> sudo vgmerge -v Data HnS
Checking for volume group "Data"
Checking for volume group "HnS"
Logical volumes in "HnS" must be inactive
---
Hmm...
>lvs|grep HnS
Media_Back HnS -wi-a---- 8.00t
Sys HnS -wc-a---- 96.00g
Sysboot HnS -wc-a---- 4.00g
Sysvar HnS -wc-a---- 28.00g
Win HnS -wi-a---- 1.00t
oHome HnS -wi-a---- 1.00t
I guess they are active. But if they aren't open, what are they
doing? And how do I make them inactive (I have a feeling this is
at the root of why lvremove never works without "-f" as well).

When it is usable, it's pretty darn fast... average between 400-500MB/s --
will have to setup a test case to see how fast 'dd' would be.
For comparison using xfsdump/restore on a 7T partition
averaged 216MB/s
(Note, using binary prefixes w/binary units (B=2^3), no
misleading confusion of decimal prefixes on binary units as
comes of 'dd' in this case)
Would be "nicer" if I didn't have to do the vgmerge first
and could do a direct move from oldVG/oldLV => newVG/newLV
(Maintaining assumptions of same-sized allocation units).
Is that planned or is there some technical reason why that
wouldn't be desirable?
Thanks for assist and someone clarifying that
"active" might be better viewed as "available".
Linda
