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.

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.)

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).

fbd0f5eed2 o move the path building functions to lib/activate/names.c 
o  Update activate.c and fs.c to use them

o  device names are now of the form <vg>:<lv>

1f9d567b23 o vgcfgrestore works ! (with the couple of examples I tried). 2002-01-15 17:37:23 +00:00
Alasdair Kergon
0092790c7d o ACTIVE is no longer a status flag - lv_active() used to check if an LV 
is active in the device-mapper.
o Many operations can be carried out regardless of whether the VG is
  active or not.
o vgscan does not activate anything - use vgchange.
o Change lvrename to support renaming of active LVs.
o Remove '//' appearing in some pathnames.
o Dummy lv_check_segments() for compilation.

b31dc66628 o Sync up todays work on converting to the segmented representation of 
logical volumes.  It includes:

   format1 changes.

   metadata.h changes.

   lv_manip.c changed (striped allocation still not done though).

   activate.c changes.

Nothing has been near a compiler as yet.

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.
