f3993cac4a Correct error message for non-snapshot activation failure. 2003-01-06 21:06:43 +00:00
Alasdair Kergon
8ef2b021ed Default stripesize 64k & config file setting for it; 
Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-)  (Same exercise required for other archs.)
Default compilation has optimisation - or else use ./configure --enable-debug

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.

d43773d634 Wow, learn something new every day. Apparently, the signed-ness of char is 
implementation-dependent; some archs (s390, arm, and ppc) default to
an unsigned char.

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.

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.)

a45f546fe0 o Use 'pvcreate --setphysicalvolumesize' with no short form (instead of -s) 
and add severe warning if it's used to make a device seem bigger than
  it really is.  This is not an option people should be using as it
  breaks metadata integrity.
o Use uint64_t throughout (rather than unsigned long long)

59d6420b9a o I decided that the archive_format shouldn't really be a format at 
all since it only supports vg_write.  It has been replaced with:

int archive_vg(struct volume_group *vg,
	       const char *dir,
	       const char *desc,
	       uint32_t retain_days,
	       uint32_t min_archive);

Joe Thornber
e74999af51 o Add cmd_line field to struct cmd_context 
o  Text format now has a description and time field at the top level.

o  archiving and backup set the description appropriately. eg,

   for an archive:

     description = "Created *before* executing 'lvextend test_vg/lvol0 -l +1'."
     creation_time = 1013166332

   for a backup:

     description = "Created *after* executing 'lvextend test_vg/lvol0 -l +1'."
     creation_time = 1013166332

This is preparing the way for a simple vgcfgundo command.

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

b926605531 o fail if create_pv_list would produce an empty list. 2002-01-21 16:15:25 +00:00
Joe Thornber
cc282870dd o Changed 
struct pv_list {
	struct list list;
	struct physical_volume pv;
   };

   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
Joe Thornber
e586401ecb o Changed find_pv_in_vg, and find_lv_in_vg to return a struct pv_list * and

444b7d2360 Add function that returns the library version. 2002-01-17 14:13:25 +00:00
Alasdair Kergon
00ee56e232 Use additional version numbers. 
Kernel driver has a version number (stored in kernel/VERSION).
  The first two components of this (0.94) give the version number of the
  ioctl interface.  This number must be changed whenever a change is
  made to the ioctl interface that breaks backwards compatibility.

  The library has a version number (stored in VERSION) which is
  used for linking.
  The first and/or second component of this must be changed whenever
  a change is made to the library API that breaks backwards
  compatibility.
 2002-01-17 13:19:55 +00:00
Alasdair Kergon
add7dc2d5a o pvcreate --uuid to specify the uuid (required before using vgcfgrestore

Alasdair Kergon
288adea256 o missing labeller free 
o updated vgcfgrestore args

  displaying command line help
 2002-01-15 21:28:04 +00:00

6198a4102c Another ioctl interface update:

Alasdair Kergon
1ed34e88aa o Add rename support to dmsetup. 
o Add support to use specified minor number to library and dmsetup.
 2002-01-11 12:12:46 +00:00
Alasdair Kergon
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.

f8427641b0 Separate constant fields from variable ones. 2002-01-10 16:47:04 +00:00
Alasdair Kergon
b80f32dd0a Clarify terminology: 
VG is resizeable  - PVs can be added or removed
  PV is allocatable - free extents on it may be allocated to LVs
 2002-01-10 15:09:51 +00:00
Alasdair Kergon
dad43063f8 Allow for multiple spellings / backwards compatibility of renamed 
command line options.
      vgchange --resizeable y
      pvchange --allocatable y
But --allocation is still allowed for both (as LVM1) and --resizable is OK.
 2002-01-10 14:46:50 +00:00

88cc3edf2e o vgcfgrestore. 2002-01-10 14:27:47 +00:00
Alasdair Kergon
952d12a5f5 o Rename many occurrences of 'backup' to 'archive' to reduce confusion. 
o Extract file creation/renaming code into a library and change backup code
  to use it too.

e59204fc22 o sync laptop to test machine. 2002-01-07 09:05:31 +00:00
Joe Thornber
6e16088e24 o High level archiving and backup functions. 
I've split the old autobackup function into two seperate areas:

'archiving' is performed *before* a vg configuration is changed.  This
produces a numbered backup in /etc/lvm/archive.

A 'backup' is performed *after* a vg change.  So the directory /etc/lvm/backup
will hold the  a copy of the current configuration.
 2002-01-03 15:46:48 +00:00

o Skip autobackup when in test mode.

Joe Thornber
1cb025cede o Shuffled completion functions around so we dont have to declare them 
at the top of the file.

o Changed completion_matches -> rl_completion_matches, and added some consts.

This will probably break things on pre readline 4.2 systems.
 2001-12-17 17:18:47 +00:00
Joe Thornber
9f23b355f7 o Changed the macro name in args.h from 'xx' to 'arg' 
o  There is now a _default_debug, and _default_verbose level, when
   using lvm interactively -vv and -dd switches just effect the current
   command.

o  Added a --quiet switch which sets both verbose and debug to zero.
 2001-12-17 16:58:17 +00:00
Joe Thornber
2d1988923c o Use lvm_snprintf 2001-12-17 14:05:43 +00:00
Joe Thornber
27f6cd0a88 o Remove LVM_CONFIG_FILE environment variable. 
o  Introduced the LVM_SYSTEM_DIR variable.

This makes more sense because the persistent cache, and backup directories
are config specific.

eg, I use /etc/lvm for running my real LV's

    but I have another directory /dev/lvm_loops that contains a config
    that allows only loopback devices, I use this for testing.
 2001-12-17 12:01:09 +00:00
Joe Thornber
8a6d1dd408 I had another look at the argument processing code: 
o You must list long args with no short option (eg. --version) at the
  front of the args.h file.

o If an argument has no short option, set the short option in args.h to '\0'

o The index into the 'the_args' var is now stored as the option value
  for getopt, iff there is no short opt.
 2001-12-17 10:08:27 +00:00

faa556e759 Add internal cache holding a 'hint' list of the PVs belonging to each VG. 
A substantial speed-up - particularly in readline mode.
If the hints turn out to be wrong, the relevant parts get thrown away.
vgscan destroys it totally.  In both cases it then rebuilds itself as
required.
