24e7745d7a devices: ignore lvm1 and pool devices 2018-05-01 15:18:47 -05:00

c1cd18f21e Remove lvm1 and pool disk formats
There are likely more bits of code that can be removed,
e.g. lvm1/pool-specific bits of code that were identified
using FMT flags.

The vgconvert command can likely be reduced further.

The lvm1-specific config settings should probably have
some other fields set for proper deprecation.

729f489009 pvcreate: don't support unpartitioned DASD devices with CDL formatted
The former patch(dab3ebce4c) is a little bit strict. For example, it is
OK to create PV on unpartitioned DASD devices with LDL formatted. So
after lvm version containing the patch, LVs created on those devices
could not be found.

9403edbb93 configure: relocate generated headers
Relocate generated configure.h and lvm-version.h outside
of compilable .c source tree.

The reason is behind - when compiling in builddir != srcdir
the generated file in lib/misc/configure.h was used for all compiled
source file except ones located in lib/misc dir - those would have used
configure.h file located in this dir - if there have existed one (i.e.
from some other build)

This problem was only visible, when srcdir == buildir was used before
trying to use  srcdri != builddir  (as configure.h appeared then in
srcdir).

1c7a509bed filters: add firmware RAID filter
Just like MD filtering that detects components of software RAID (md),
add detection for firmware RAID.

We're not adding any native code to detect this - there are lots of
firmware RAIDs out there which is just out of LVM scope. However,
with current changes with which we're able to get device info from
external sources (e.g. external_device_info_source="udev"), we can
do this easily if the external device status source has this kind
of information - which is the case of "udev" source where the results
of blkid scans are stored.

This detection should cover all firmware RAIDs that blkid can detect and
which are identified as:
  ID_FS_TYPE = {adaptec,ddf,hpt45x,hpt37x,isw,jmicron,lsi_mega,nvidia,promise_fasttrack,silicon_medley,via}_raid_member

8a843d0d97 filters: add "usable device" filter
Usable device filter is responsible for filtering out unusable DM devices.
The filter has 3 modes of operation:

  - FILTER_MODE_NO_LVMETAD:
    When this mode is used, we check DM device usability by looking:
      - whether device is empty
      - whether device is blocked
      - whether device is suspended (only on devices/ignore_suspended_devices=1)
      - whether device uses an error target
      - whether device name/uuid is reserved

  - FILTER_MODE_PRE_LVMETAD:
    When this mode is used, we check DM device usability by looking:
      - whether device is empty
      - whether device is suspended (only on devices/ignore_suspended_devices=1)
      - whether device uses an error target
      - whether device name/uuid is reserved

  - FILTER_MODE_POST_LVMETAD:
    When this mode is used, we check DM device usability by looking:
      - whether device is blocked
      - whether device is suspended (only on devices/ignore_suspended_devices=1)

These modes will be used by subsequent patch to create different
instances of this filter, depending on lvmetad use.

b94a3ee9f6 cache: Add functions that create/remove cache LVs
A cache LV - from LVM's perpective - is a user accessible device that
links the cachepool LV and the origin LV.  The following functions
were added to facilitate the creation and removal of this top-level
LV:
1) 'lv_cache_create' - takes a cachepool and an origin device and links
   them into a new top-level LV of 'cache' segment type.  No allocation
   is necessary in this function, as the sub-LVs contain all of the
   necessary allocated space.  Only the top-level layer needs to be
   created.

2) 'lv_cache_remove' - this function removes the top-level LV of a
   cache LV - promoting the cachepool and origin sub-LVs to top-level
   devices and leaving them exposed to the user.  That is, the
   cachepool is unlinked and free to be used with another origin to
   form a new cache LV; and the origin is no longer cached.
   (Currently, if the cache needs to be flushed, it is done in this
   function and the function waits for it to complete before proceeding.
   This will be taken out in a future patch in favor of polling.)

90bbed3255 cache: New 'cachepool' segment type
This patch adds the new cachepool segment type - the first of two
necessary to eventually create 'cache' logical volumes.  In addition
to the new segment type, updates to makefiles, configure files, the
lv_segment struct, and some necessary libdevmapper flags.

The cachepool is the LV and corresponding segment type that will hold
all information pertinent to the cache itself - it's size, cachemode,
cache policy, core arguments (like migration_threshold), etc.

5590448c32 Misc: Move some thin pool functions to a new file
Functions that handle set-up, tear-down and creation of thin pool
volumes will be more generally applicable when more targets exist
that make use of device-mapper's persistent data format.  One of
these targets is the dm-cache target.  I've selected some functions
that will be useful for the cache segment type to be moved, since
they will no longer be thin pool specific but are more broadly
useful to any segment type that makes use of a 'pool' LV.

80bcdb93ff filters: check for mpath before opening devs
Split out the partitioned device filter that needs to open the device
and move the multipath filter in front of it.

When a device is multipathed, sending I/O to the underlying paths may
cause problems, the most obvious being I/O errors visible to lvm if a
path is down.

Revert the incorrect <backtrace> messages added when a device doesn't
pass a filter.

Log each filter initialisation to show sequence.

Avoid duplicate 'Using $device' debug messages.

07113beea3 Do not scan device if it is part of active multipath.
Add filter which tries to check if scanned device is part
of active multipath.

Firstly, only SCSI major number devices are handled in filter.

Then it checks if device has exactly one holder (in sysfs) and
if it is device-mapper device and DM-UUID is prefixed by "MPATH-".

If so, this device is filtered out.

The whole filter can be switched off by setting
mpath_component_detection in lvm.conf.

Extend the existing reporting infrastructure definitions and structures

a 'get' and 'set' function for each of these fields, which will be utilized
by exported lvm2app functions.

Define a default _not_implemented 'get' and 'set' function that just sets
an errno and returns 0.  Future patches will actually implement the
specific 'get' and 'set' functions for each property.  For read-only
properties, only the 'get' function will be implemented.

Define vg_get_property() function to query a property.  We will call
this from a lvm2app function.

c737d34804 Use vpath instead of VPATH.
Usage of VPATH makes troubles when used within $(builddir).
Not only source files are being found through VPATH,
but targets as well. (make --debug=v)

Thus if user builds the code in $(srcdir) and also in some $(builddir)
he gets mangled results as some generated files (i.e. .export.sym)
are 'reused' from $(srcdir) instead of $(builddir).

This patch switches to use vpath were we could explicitly name
suffixes that should be looked via vpath - we must take care,
we do not generate files with these suffixes:
.c, .in, .po, .exported_symbols
