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

568d7229bf Review locking: block signals instead of ignoring them and restore state
afterwards; avoid race condition with unlink; add LCK_HOLD to process_each_vg.

e09a7b5787 o dm_destroy_all() called on exit - but doesn't touch suspended devices yet.
o 'dmsetup remove_all' calls dm_destroy_all() to provide a quick way to
  prepare for unloading the module
o Ran through indent again.

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.)

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?

187cf4c97d o Convert lv->id back to lv_number when writing back to disk
o Use first unused lv_number when creating new LV
o Use lv_number for refs to snapshots
o Update persistent minor logic after the lvcreate restructure
o Reset all parameters before use in lvcreate.

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)
   This zeroes the start of the cow device.

o  Made lvcreate call above fn.

052360e901 o split lvcreate into seperate functions for parsing the command line,
and creating the lv.  A lot of changes in here so be on the lookout
   for bugs.

60274aba6e Preparation for an LVM2 liblvm - pass cmd_context into each tool and
link some globals that the tools need into that structure.

7d0e6e800e o Support locking with local lock files
o Disable control-c during updates (except if blocked waiting for a lock)
2002-02-11 15:42:34 +00:00
Joe Thornber
03888774a5 o Added functions to display what's in the archive.
o  For now vgcfgrestore -l <vg> displays this list.

A bit hacky, but it'll get better.

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.

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
