fc8b7efc6f 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.)

493c53d090 o Add a line to lvdisplay to say if the volume is a snapshot. 2002-03-04 15:12:30 +00:00

b27e956d35 o Bad dependency, meant the origin was always getting activated. 2002-03-04 15:10:30 +00:00

7bfdb5f77f o I was tearing down device bottom-up instead of top down. Which
is why lvremove of snapshots wasn't working.

8d8c02317f o Break creating a snapshot down into:
i)   create cow
   ii)  activate cow
   iii) zero cow
   iv)  deactivate
   v)   add snapshot info
   vi)  reactivate

8d3afaa53c More use of LV locking. 2002-03-01 19:08:11 +00:00
Joe Thornber
7ced9ef3df o point snapshots at origin:real rather than origin:top, and *ping*
snapshots work.

73a88ab3d3 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?

de7f7b96db o Format1 wasn't recording the snapshot chunk size properly
o  Activation of snapshots now works - though the resulting device
   doesn't (pjc ?)

o  text format wasn't setting vg->cmd.

333af9b13a o _build_name was allocating 1 byte too few, which meant the
terminating zero was falling off at some later point.

o Don't try and iterate from a deleted node in _prune_unmarked.

a5bca5e240 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.

cf510897f1 Begin conversion so LV id is passed to activation unit instead of
struct logical_volume.

1d171345f8 o Sync with cvs, dev_manager still needs to be wired into activate.c 2002-02-25 12:02:33 +00:00

Joe Thornber
83a8021515 o Added a macro called hash_iterate, that is similar to list_iterate
o Renamed hash_iterate function, hash_iter.

Sort of seems to work.

6d94578955 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.

2f5a3c2bbe Remove VG arg from lv_is_cow() and lv_is_origin() - use lv->vg instead. 2002-02-20 19:04:55 +00:00

f6485616cd 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

426dc7836c 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.

4849e8cd6d o snapshot support for the text format.
The logical_volumes, and snapshots sections of the text format are now
optional.

77e3b460aa o First pass at format1 snapshot support. 2002-02-13 11:43:29 +00:00
Joe Thornber
b5321001f8 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.

ea6f399454 o Turn the device_create_* functions into device_populate_*, they only
fill in an already created dm_task.  This allows common code, such
  as minor number selection, and read_only to be lifted.
