a2f4ccd839 lvcreate: add --activate ay (autoactivate)
One can use "lvcreate --aay" to have the newly created volume
activated or not activated based on the activation/auto_activation_volume_list
this way.

Note: -Z/--zero is not compatible with -aay, zeroing is not used in this case!
When using lvcreate -aay, a default warning message is also issued that zeroing
is not done.

2729720fd3 args: add --activate synonym for --available arg
We're refererring to 'activation' all over the code and we're talking
about 'LVs being activated' all the time so let's use 'activation/activate'
everywhere for clarity and consistency (still providing the old
'available' keyword as a synonym for backward compatibility with
existing environments).

34a45b0029 Fix warn message and update man page
Fix regression in man page. The chunk size is in kilobyte units on command line
input though in the source code we work with sector size unit
so make it clear in the man page.

Update chunksize for thin pool in man page - it's max value is 1024M == 1G.

Fix warning range message to show proper max value.

90423c1200 Fit thin pool metadata into 128MB
If the lvcreate may decide some automagical values for a user,
try to keep the pool metadata size into 128MB range for optimal
perfomance (as suggested by Joe).

So if the pool metadata size and chunk_size were not specified,
try to select such values they would fit into 128MB size.

d81498a824 Initialize dmeventd monitoring for every command
Read lvm.conf setting for monitoring for each command. So we should not
activate monitoring if the default compilation is set to monitor during
lvconvert commnads.

Patch also removes check for  clustered VG and allows to disable monitoring
for clustered VG with the assumption, the problem with monitoring and dmeventd
flag passing for INGNORE is already fixed.

4fbde0143a Support rounding of percentage upward
We want to keep this logic -
when LV is extend - extend the LV by at least given amount,
when LV is reduced - reduce the LV by at most given amount.

So for this the rounding needs to be used.
Current logic which seems to satisfy give rule is to round up all
extent values for LV resize upward except for values with '-' sign
that are round downward.

This patch also fixes the problem when  lvextend --use-polices tried
to extend LV the by i.e. 20% - but the resulting 20% were smaller
the extent size thus before this patch no extension happened.

f989a55539 Disallow the creation of mirrors (mirror or raid1 segtype) with only one leg.
If you specify the segment type (e.g. --type mirror) and the mirrors argument
as zero, it would result in a mirrored LV with only one image.  While the device
may be valid in theory, it should not be allowed in practice.  It also makes it
difficult on the conversion tools, since they react badly to single-image
mirrors.

09c4fd3f55 cosmetic change - swapping one macro for another
When I see 'seg_is_mirrored', I expect the argument to be an lv_segment.
In this case, it is lvcreate_params.  Both structures, have a 'segtype'
entry which the macro dereferences.  However, it just seems easier to
understand if we do 'segtype_is_mirrored' instead.

aec2115410 Const fixing
Fixing some const warnings - with API change in:

int vg_extend(struct volume_group *vg, int pv_count, const char *const *pv_names,

Change is needed - as lvm2api expects const behaviour here.
So vg_extend() is doing local strdup for unescaping.

skip_dev_dir return const char* from const char* vg_name.

Rest of the patch is cleanup of related warnings.

Also using dm_report_filed_string() API change to simplify
casting in _string_disp and _lvname_disp.

called by their respective process_each_..() method.

c42b235610 Move _lvcreate into the internal library and rename to lv_create_single.
After some refactorings, we can now move the bulk of _lvcreate into the
internal library, and we can call from liblvm.  In the future, we should
refactor lv_create_single further, probably by segtype, to reduce the
size of struct lvcreate_params.  For now this is a reasonable refactor
and allows us to re-use the function from liblvm.

4c611a220a Fix vg_read() error paths to properly release upon vg_read_error().
Fix vg_read() error paths to properly release upon vg_read_error().
Note that in the iterator paths (process_each_*()), we release
inside the iterator so no individual cleanup is needed.  However there
are a number of other places we missed the cleanup.  Proper cleanup
when vg_read_error() is true should be calling vg_release(vg), since
there should be no locks held if we get an error (except in certain
special cases, which IMO we should work to remove from the code).

Unfortunately the testsuite is unable to detect these types of memory
leaks.  Most of them can be easily seen if you try an operation
(e.g. lvcreate) with a volume group that does not exist.  Error
message looks like this:
  Volume group "vg2" not found
  You have a memory leak (not released memory pool):

8f3fd69ffa Move metadata backup call after vg_commit.
The backup() call store metadata from memory.

But in cluster backup() call performs
remote nodes metadata backup and it reads data from disk.

For metadata backup consistency,
patch moves all backup() calls after vg_commit.

(Moreover, some tools already do that this way.)

7f436a0f39 Fix lv_count when manipulating with snapshots and max_lv is set.
Patch fixes these problems:
 - during the snapshot creation process, it needs create 2 LVs,
   one is cow, second becomes snapshot.
   If the code fails in vg_add_snapshot, code lvcreate will not remove
   LV cow volume.

 - if max_lv is set and VG contains snapshot, it can happen that
   during the activation lv_count is temporarily increased over the limit
   and VG metadata are not properly processed
   see https://bugzilla.redhat.com/show_bug.cgi?id=490298

 - vgcfgrestore alows restore with max_lv set to lower valuer that actual
   LV count. This later leads to situation that max_lv is completely ignored.

 - vgck doesn't call vg_validate(). It should at least try:-)

64119287c3 - change new log_ARG variable to more explicit mirrorlog_ARG. 2007-08-09 21:25:08 +00:00
Jonathan Earl Brassow
19583d115c This patch changes the arguments that specify the mirror
log type.  Previously, we had a '--corelog' argument that
would change the default type from 'disk' to 'core'.  I
think that creates too much confusion - especially when
doing conversions on mirrors.

The new argument '--log' takes either "disk" or "core"
as a parameter.  This could be expanded in the future
for additional logging types as well.

Examples:
# Creating a 2-way mirror
$> lvcreate -m1 ... # implicitly use default disk logging
$> lvcreate -m1 --log disk ... # explicit disk logging
$> lvcreate -m1 --log core ... # specify core logging
$> lvcreate -m1 --corelog ... # old way still works

# Conversion examples
$> lvconvert --log core ... # convert to core logging
$> lvconvert --log disk ... # convert to disk logging
$> lvconvert -mX --corelog ... # old way still works
$> lvconvert -mX ... # old way of converting to disk logging still works

Changes are reflected in the man pages.

50762c2186 agk, I recall you saying you had a massive commit pending; if you need me
to back this out so you can do that commit, let me know.  Also, if there's
an issue with the error message that's displayed, just change it in tools.h.

This causes a "device-mapper driver/module not loaded?" error message to
be displayed for the commands that require dm-mod, if the tools can't get
the driver version.  It's not done for commands that don't require dm-mod.
This should clear up some problems people have had attempting to use lvm2
without rtfm'ing.

7cc602c800 i) Add the VISIBLE flag to the text format. (Other changes are pending
for lib/activate.)

097d49e73d i) There's now a seperate field in struct logical_volume that stores the
allocation policy.  This can currently take one of three values:

   typedef enum {
        ALLOC_NEXT_FREE,
        ALLOC_STRICT,
        ALLOC_CONTIGUOUS
   } alloc_policy_t;

    Notice that 'SIMPLE' has turned into the slightly more meaningful NEXT_FREE.

ii) Put code into display.[hc] for converting one of these enums to a
    text representation and back again.

ii) Updated the text format so this also has the alloc_policy field.

25b733809a Merge with text format branch.
Lots of changes/very little testing so far => there'll be bugs!

Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files.  Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.

Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).

e.g. metadata {
        dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}

Plenty of refinements still in the pipeline.

8573c6bcac Snapshots are now attached to their origin device for locking purposes
so lock the origin instead of the snapshot itself when creating one.

eea1d6932c o Top level device is now just called <vg>-<lv> (there's no 'top'
layer appended).

o  Got rid of the unused layer->type field and enum.
2002-03-07 15:29:31 +00:00
Alasdair Kergon
15c325f06a o Use new LCK_HOLD flag to indicate whether lock should be held on return
from lock_vol() - otherwise it now attempts to acquire the lock and then
  immediately releases it.
o Extend the id field in struct logical_volume to hold VG uuid + LV uuid
  for format1. This unique lvid can be used directly when calling lock_vol().
o Add the VG uuid to vgcache to make VG uuid lookups possible.  (Another
  step towards using them instead of VG names internally.)

812c699c8d Basic support for persistent minor numbers;
slightly different from the current LVM1 method.

  lvcreate --persistent y  --minor 10   (to specify when created)
  lvchange --persistent n  (to turn off)
  lvchange --persistent y  --minor 11   (to change)

--persistent uses a new LV status flag stored on disk
minor number is stored on disk the same way as LVM1 does
(but major number stored is 0; any LVM1 major/minor setting gets lost)

  lvchange -ay --minor 12 (to activate using minor 12, regardless of the
                           on-disk setting, which doesn't get changed)

--minor == -m
--persistent == -M

   to

   struct pv_list {
	struct list list;
	struct physical_volume *pv;
   };


o  New function in toollib 'create_pv_list', which creates a list of pv's
   from a given command line array of pv's.

o  Changed lvcreate/extend to use this (fixes lvextend [pv list] bug).
2002-01-21 16:05:23 +00:00

e586401ecb o Changed find_pv_in_vg, and find_lv_in_vg to return a struct pv_list * and
struct lv_list * respectively.

4a624ca055 o ACTIVE is no longer a status flag - lv_active() used to check if an LV
is active in the device-mapper.
o Many operations can be carried out regardless of whether the VG is
  active or not.
o vgscan does not activate anything - use vgchange.
o Change lvrename to support renaming of active LVs.
o Remove '//' appearing in some pathnames.
o Dummy lv_check_segments() for compilation.
