Update pool conversion function to handle also conversion of
thick LV to thin LV by moving thick LV into thin pool data LV
and creating fully provissioned thin LV on top of this volume.
Reworking existing conversion to use insert_layer_for_lv co
the uuid is now kept with thin-pool - this should however not
really matter as we are doing full deactivation & activation cycle.
With conversion to thin LV user can use same set of arguments
to set chunk-size.
TODO: add some smart code to decide best values for chunks sizes.
For proper functionality of insert_layer_for_lv we need to
move more bits to layerd LV.
Add some missing new types and correct usage of caller,
so the new LV type is set after the movement.
Validate cache origin in front of the prompt.
Also add some rules to command description file.
TODO:
more validation needed also for lvcreate,
more complex rules with "OR" seems to be needed.
Avoid activation when going to skip zeroing of 'error' segtype
(so it's not erroring out).
Also skip zeroing for 'zero' segtype LV (already being zero).
When lvm2 calculates the maximal usable COW size and crops the user
requested size to this value, don't return the error result from
the 'lvextend' operation.
We already apply the same logic when resizing thin-pool beyond
the supported maximal size.
FIXME: The return code error logic here is somewhat fuzzy.
This vdo parameter existed in the early stage of integration of vdo into lvm2,
but later it's been removed from vdoformat tool - so actually if
there would be any non-zero value it would cause error on lvcreate.
Option was not stored on disk in lvm2 metadata.
Remove this vdo parameter from lvm2 sources.
(Although this vdo parameter will be still accepted on cmdline through
--vdosettings option, but it will be ignored.)
The recent fix 05c2b10c5d0a9 ensures that raid LV images are not
using the same devices. This was happening in the lvextend commands
used by this test, so fix the test to use more devices to ensue
redundancy.
In case of e.g. 3 PVs, creating or extending a RaidLV causes SubLV
collocation thus putting segments of diffent rimage (and potentially
larger rmeta) SubLVs onto the same PV. For redundant RaidLVs this'll
compromise redundancy. Fix by detecting such bogus allocation on
lvcreate/lvextend and reject the request.
lvreduce uses _lvseg_get_stripes() which was unable to get raid stripe
info with an integrity layer present. This caused lvreduce on a
raid+integrity LV to fail prematurely when checking stripe parameters.
An unhelpful error message about stripe size would be printed.
There is no easy way to detect, whether device supports zeroing,
and kernel also zeroes device when it's not directly supported,
but with extra message:
operation not supported error, dev X, sector Y op 0x9:(WRITE_ZEROES)...
So to avoid generating such message with every 'lvcreate', use for
zeroing of upto 8K just standard write of zeroed page.
(maybe we can go with even larger sizes).
Remove old code that became incorrect at some point.
It's probably a fragment of an old condition that was left
behind because it wasn't understood. We don't want to drop
the MISSING_PV flag just because the PV has no mda in use.
The device that was missing may have stale data, so the user
needs to decide if the device should be removed or restored.
It looks like force was not being used to enable crypt resize,
but rather to force an inconsistency between LV and crypt
sizes, so this is either not needed or force in this case
should have some other meaning.
This reverts commit ed808a9b548ca59221d512bfb7ae581e8367fe50.
Update previous commit
"lvresize: only resize crypt when fs resize is enabled"
to enable crypt resizing when --force is set and --resizefs
is not set. This is because it's been allowed in the past
and people have used it, but it's not a good idea.
There were a couple of cases where lvresize, without --fs resize,
was resizing the crypt layer above the LV. Resizing the crypt
layer should only be done when fs resizing is enabled (even if the
fs is already small enough due to being independently reduced.)
Also, check the size of the crypt device to see if it's already
been reduced independently, and skip the cryptsetup resize if
it's not needed.
Enhance checking vdo constains so it also handles changes of active VDO LVs
where only added difference is considered now.
For this also the reported informational message about used memory
was improved to only list consuming RAM blocks.
Introduce struct vdo_pool_size_config usable to calculate necessary
memory size for active VDO volume.
Function lv_vdo_pool_size_config() is able to read out this
configuration out of runtime DM table line.
18722dfdf4d3 lvresize: restructure code
mistakenly changed the overprovisioning check from applying
to all lv_is_thin_type lvs to only lv_is_thin_pool lvs, so
it no longer applied when extending thin lvs. The result
was missing warning messages when extending thin lvs.
When executing process_each_lv_in_vg, we process live LVs first and
after that, we process any historical LVs. In case we have just removed
an LV, which also means we have just made it "historical" and so it
appears as fresh item in vg->historical_lvs list, we have to skip it
when we get to processing historical LVs inside the same process_each_lv_in_vg
call.
The simplest approach here, without introducing another LV list, is to
simply mark such historical LVs as "fresh" directly in struct
historical_logical_volume when we have just removed the original LV
and created the historical LV for it. Then, we just need to check the
flag when processing historical LVs and skip it if it is "fresh".
When we read historical LVs out of metadata, they are marked as
"not fresh" and so they can be processed as usual.
This was mainly an issue in conjuction with -S|--select use:
# lvmconfig --type diff
metadata {
record_lvs_history=1
}
(In this example, a thin pool with lvol1 thin LV and lvol2 and lvol3 snapshots.)
# lvs -H vg -o name,pool_lv,full_ancestors,full_descendants
LV Pool FAncestors FDescendants
lvol1 pool lvol2,lvol3
lvol2 pool lvol1 lvol3
lvol3 pool lvol2,lvol1
pool
# lvremove -S 'name=lvol2'
Logical volume "lvol2" successfully removed.
Historical logical volume "lvol2" successfully removed.
...here, the historical LV lvol2 should not have been removed because
we have just removed its original non-historical lvol2 and the fresh
historical lvol2 must not be included in the same processing spree.
