5295f36cb4 o knock out the offset for origin targets. 2002-03-08 10:45:01 +00:00
Joe Thornber
4526747997 o Add active_list to dev_manager 
o  Origin layer is only added to snapshots if a snapshot is in the
   active_list.

11d2da4036 o First cut at dev scanning. 
o  Split up _expand_lv
 2002-03-07 17:37:38 +00:00
Joe Thornber
0fe3a2c512 o Add comment describing what we're aiming for with dev_manager. 
o  Remove dev_manager_reactivate, since it'll be the same as activate.

o  Merge the mark, visible and dirty fields into the same flags field.

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.

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.)

3a84c18bdd o I was tearing down device bottom-up instead of top down. Which 
is why lvremove of snapshots wasn't working.

Joe Thornber
9db196e6c5 o Break creating a snapshot down into: 
i)   create cow
   ii)  activate cow
   iii) zero cow
   iv)  deactivate
   v)   add snapshot info
   vi)  reactivate

f4cbeaf0ac o Lock mechanism for LV activation 
o #defines for common lock flag combinations
o Try out hyphens instead of colons in device-mapper names - does this
  make messages containing filenames easier to read?

841da63e77 o Format1 wasn't recording the snapshot chunk size properly 
o  Activation of snapshots now works - though the resulting device
   doesn't (pjc ?)

349f09e401 o _build_name was allocating 1 byte too few, which meant the

de6c918392 o Removed old files 
o  rewrote activate.c to use dev-manager, I'm sure these two will merge
   at some point.

o  Rename is broken ATM

o  dev-manager puts the calls through to fs.c for layers that have the
   'visible' flag set.

Alasdair Kergon
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)
o Convert a few messages that contain pathnames into the more common form:
  pathname: message

5986ec940f o Removed the -z (suspend) option from the tools 
o  New function: int lv_setup_cow_store(struct logical_volume *lv)

294ddff8a6 o snapshot support for the text format. 
The logical_volumes, and snapshots sections of the text format are now
optional.
 2002-02-13 13:29:16 +00:00
Joe Thornber
0a9f8bcf97 o First pass at format1 snapshot support. 2002-02-13 11:43:29 +00:00
Joe Thornber
7d68b08028 o First changes to add snapshot support. 
I'm taking a different route from LVM1 here in that snapshots are a
seperate entity from the logical volumes, I think of them as an
application of an LV (or two lvs rather).  As such there is a list of
snapshots held against the vg, and there is *not* a SNAPSHOT, or
SHAPSHOT_ORG flag in lv->status.

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);

which is now called directly by tools/archive.c
 2002-02-08 11:58:18 +00:00
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.

d6750e9d76 lv->minor >= 0 (ejt) 2002-02-04 13:08:31 +00:00
Alasdair Kergon
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

7ae5a778d5 Basic support for (read-only) partial activation if any PVs are 
missing from a VG.  (Linear targets use the device-mapper 'error' target
which returns ioerror; striped targets use '/dev/ioerror' for now - which must
already exist e.g. as a sufficiently large block device version of /dev/zero).

4b2ec1929a o There were some alignment problems with pool-debug which I've resolved 
by allocating the data block with an additional dbg_malloc.

o  Added an assertion to check that no one is requesting alternate

   for LVM2.

77712b1ecb Set pv->pe_size when reading in text-file backup.

a PV that belongs to a VG?

c50c2886f7 Don't bother to write out an empty cache. 2002-01-24 23:17:16 +00:00
Alasdair Kergon
b849de1d18 Fix the device cache to cope reasonably safely with device name changes. 
This should be a rare occurrence so the aim is to recover if it's
straightforward to do so, otherwise just to abort the operation.
If people *knowingly* change device names, they should always run vgscan
afterwards.

A few bytes of memory gets leaked inside a pool each time an alias
has to be discarded - it's not worth restructuring the code to reuse it.

More of LVM2 needs updating to pass device objects (or uuids) about
instead of pathnames so that resolution of pathname->object only happens
once per operation.

dev_cache_get() should now always return the *current* device at the path given

dev_name_confirmed() replaces dev_name() whenever it's important to
know that name for the device is still current (ie when opening it).
If the cache doesn't know a current name, the function fails.

dev_open() guarantees that the file descriptor returned is for the dev_t
of the device structure it was passed.

Alasdair can you look at changing display.c to use to output the mappings
in a more segment oriented format please ?

I haven't put the span list into struct physical_volume to represent allocated
extents.  I think the burden of maintaining it for things like lv_extend may
out weigh it's uses.

d1b28647ed o First pass at the regex code. lib/regex/matcher takes an array of regex's 
and builds a *very* efficient engine that will tell you which regex a string
  matches with only a single pass through the string.  To be used in the config
  file when specifying devices.

o Anchor's aren't supported yet (^ and $) but that won't take long.

o Also when we get some realistic config files we may want to consider adding an
  extra level of indirection to the dfa state in order to compress the table.
  It all depends on how large typical tables get.

a53d451f30 o Ok, this seems to be a much better method for caching valid 
devices based on /proc/devices
   + The dev_mgr structure now has a 256 element char array that is
     initially all 0s
   + When a match is found, the array element corresponding to the major
     number of the match is set to a non-zero value
   + to check for a match, all one has to do is check that the array
     element at the major number in question is non-zero.
 o I'm wondering if we should do this with bitwise operators instead?  Does
   anyone expect the major numbers to grow larger than 8-bits?
