We incorrectly marked pv_major and pv_minor fields as being of string
type, even though the values were already correctly handled as integers
internally. This confused -S|--select that tried to compare string
values instead of integers.
Reported here: https://github.com/lvmteam/lvm2/issues/122
Replace the use of internal /dev/mapper names with the use of
public LV names /dev/vg/lv for use with repair tools.
For this make the activation of _pmspare LV to be handled as
a component activation with public name.
Metadata is already atomatically activated this way (as readonly).
So if there is any 'error' happening, we leave public LVs in
system.
Last commit c38b668fc3 was pushed
with type 'scanf' instead of 'sscanf' needed for buffer reading.
Interestingly this caused scanning from 'stdin' descriptor and
thus failures in lvm shell usage.
The code in init_log_file relies on the process name (COMM) to not
contain whitespaces. This change fixes it by looking up the right-most
parenthesis to safely jump past COMM.

Code is only used with testing, so it should have no impact on regular
users.

With 3596558861 it's been introduced
a more fine grained description.
However 'disabled' might be actually more confusing then empty field,
so keep only the info about 'not enabled'aka dmevend is not allowed
to monitor LV which otherwise could be monitored.
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.)
Fix in the code that matches devices to system.devices entries when
the devices have the same serial number. A non-PV device in
system.devices has no pvid value, and the code was segfaulting
when checking the null pvid value.
In previous lvm versions, trailing spaces at the end of a t10 wwid would
be replaced with underscores, so the IDNAME string in system.devices
would look something like "t10.123_". Current versions of lvm ignore
trailing spaces in a t10 wwid, so the IDNAME string used would be
"t10.123". The different values would cause lvm to not recognize a
device in system.devices with the trailing _. Fix this by ignoring
trailing underscores in the IDNAME string from system.devices.
The recent fix 05c2b10c5d 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.
