d23e948216 Move is_empty_dir to lvm-file 2002-03-11 22:23:24 +00:00
Joe Thornber
58bdaa31f0 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
b6491d88a6 o This should complete the dev_manager alg. Please could people now 
report any activation oddities they see.

f6061ba62e lv_info replaces lv_active etc. 2002-03-11 19:02:28 +00:00

427899ddce o activate/reactivate merge 
o unlocking macro
 2002-03-11 15:08:39 +00:00

c4ab7d2dbd 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
0fd2ba033f 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
ed38939a93 o knock out the offset for origin targets. 2002-03-08 10:45:01 +00:00
Joe Thornber
c7ee26ce5a 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
2ec8656bea o First cut at dev scanning. 
o  Split up _expand_lv
 2002-03-07 17:37:38 +00:00
Joe Thornber
b2ef256910 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
63d6ce95db 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
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.)

a1c2d9c0f3 Fix activation for VG with more than one LV. 2002-03-04 18:50:34 +00:00
Joe Thornber
b27e956d35 o Bad dependency, meant the origin was always getting activated. 2002-03-04 15:10:30 +00:00

35ebed75c6 Remove unused fns. 2002-03-04 14:27:25 +00:00
Joe Thornber
7bfdb5f77f 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
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
 2002-03-04 13:46:37 +00:00

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.
 2002-03-01 09:07:00 +00:00
Alasdair Kergon
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?
 2002-02-27 12:26:41 +00:00
Joe Thornber
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.

1a669b3e68 Clearer link pathname display. 2002-02-26 16:08:22 +00:00
Joe Thornber
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.
 2002-02-26 14:44:13 +00:00
Joe Thornber
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.

c885633e02 o More dev_manager fns. 2002-02-25 16:53:12 +00:00

545e11a3d7 o In go the populate functions. 2002-02-25 15:19:53 +00:00
Joe Thornber
44f5287664 o More dev_manager work. 2002-02-25 14:46:57 +00:00

cf510897f1 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
1d171345f8 o Sync with cvs, dev_manager still needs to be wired into activate.c 2002-02-25 12:02:33 +00:00

3698eaa2d2 Remove lv_update_write_access: use lv_reactivate directly now instead. 2002-02-20 21:28:22 +00:00
Joe Thornber
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.
 2002-02-18 15:52:48 +00:00
Joe Thornber
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.

c4856caebb Preparation for an LVM2 liblvm - pass cmd_context into each tool and 
link some globals that the tools need into that structure.

fc1030bb22 Now that most of the usage of 'stack' only occurs when there's an error, 
don't suppress it from the screen output any longer.

a56fa1558b o Split activate.c into a high level (remaining in activate.c) and low level (ll-activate.[hc]) API. 
o  Creation of a device from an lv now lives in activate-lv.c

71958bc0f1 lv->minor >= 0 (ejt) 2002-02-04 13:08:31 +00:00
Alasdair Kergon
366ec35612 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

aa8d8bc8b5 Propagate volume group read-only setting down to its logical volumes. 
(Might sometimes be safe to relax this restriction.)
 2002-01-30 17:12:14 +00:00

0800dcfdc4 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).

1349b79728 Only remove symbolic links when deactivating. 
(if this code didn't create it, don't delete it)
