bb13858120 o Actually check that the vg directory is empty rather than speculatively 
rmdiring it.  Work around for devfs bug.
 2002-03-11 20:43:58 +00:00
Joe Thornber
2ec94d4daf o This should complete the dev_manager alg. Please could people now 
report any activation oddities they see.

41967a0276 lv_info replaces lv_active etc. 2002-03-11 19:02:28 +00:00

be326a2f1b o activate/reactivate merge 
o unlocking macro
 2002-03-11 15:08:39 +00:00

323a167b49 o dm->active_list now filled in, ATM this is based on the layer name rather 
than the uuid.
 2002-03-11 11:27:48 +00:00
Joe Thornber
fd6932b18b o Comment out some new code that was preventing pjc activating 
snapshots.  This will go back in when the active_list is working.
 2002-03-11 10:38:16 +00:00
Joe Thornber
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.
 2002-03-08 10:41:48 +00:00
Joe Thornber
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.
 2002-03-07 16:48:46 +00:00
Joe Thornber
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.)

2731508b34 Fix activation for VG with more than one LV. 2002-03-04 18:50:34 +00:00
Joe Thornber
fdec53fb9c o Add a line to lvdisplay to say if the volume is a snapshot. 2002-03-04 15:12:30 +00:00
Joe Thornber
d30321a6cf o Bad dependency, meant the origin was always getting activated. 2002-03-04 15:10:30 +00:00
Alasdair Kergon
3bf898526a Remove unused fns. 2002-03-04 14:27:25 +00:00
Joe Thornber
3a84c18bdd o I was tearing down device bottom-up instead of top down. Which 
is why lvremove of snapshots wasn't working.
 2002-03-04 14:26:43 +00:00
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

8c013da41f More use of LV locking. 2002-03-01 19:08:11 +00:00
Joe Thornber
6ed0234393 o point snapshots at origin:real rather than origin:top, and *ping* 
snapshots work.
 2002-03-01 09:07:00 +00:00
Alasdair Kergon
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?
 2002-02-27 12:26:41 +00:00
Joe Thornber
841da63e77 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.

6761081ab4 Clearer link pathname display. 2002-02-26 16:08:22 +00:00
Joe Thornber
349f09e401 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.
 2002-02-26 14:44:13 +00:00
Joe Thornber
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.

c15334eb4e o More dev_manager fns. 2002-02-25 16:53:12 +00:00
Joe Thornber
999e584511 o In go the populate functions. 2002-02-25 15:19:53 +00:00
Joe Thornber
fc28b60f9c o More dev_manager work. 2002-02-25 14:46:57 +00:00
Alasdair Kergon
413cc9189e Begin conversion so LV id is passed to activation unit instead of 
struct logical_volume.
 2002-02-25 12:56:16 +00:00
Joe Thornber
ca73e23fd0 o Sync with cvs, dev_manager still needs to be wired into activate.c 2002-02-25 12:02:33 +00:00
Joe Thornber
7b9e789f9c o Remove the vg argument from find_cow 2002-02-25 11:55:39 +00:00
Joe Thornber
b00094bdeb o hash_iterate -> hash_iter 2002-02-25 11:54:15 +00:00
Joe Thornber
7e682f4f93 o Added a macro called hash_iterate, that is similar to list_iterate 
o Renamed hash_iterate function, hash_iter.

6f3a8d5bd3 Fill in format_text functions. 
Sort of seems to work.
 2002-02-22 11:44:56 +00:00
Alasdair Kergon
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.

e680d3190f o typo 2002-02-21 10:17:01 +00:00

0e32e054df o add find_cow function. 2002-02-21 10:16:33 +00:00

cc8b2cd706 Try out using LV locking for reactivation. 2002-02-20 21:30:27 +00:00

b6afcf6458 Remove VG arg from lv_is_cow() and lv_is_origin() - use lv->vg instead. 2002-02-20 19:04:55 +00:00
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
 2002-02-20 18:29:30 +00:00
Joe Thornber
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.
 2002-02-18 15:52:48 +00:00

d7783cc8b8 o small bug in the format1 export code for snapshots. 
o  tidied newlines in the snapshot section of format text.
