0a109fbd03 The LVM2 part of vgmknodes [still to do the non-devfs device-mapper bit]. 2003-11-12 19:16:48 +00:00

1d3e407c8f o Rejig activation code device dependencies to make things a bit more robust
and further reduce the number of ioctl calls made.
o Metadata area struct change.
o Make config file accessible to activation functions & get stripe_filler
  from it.
o Allow kernel to return snapshot status as a fraction or a percentage.

dd2157534b Default stripesize 64k & config file setting for it;
Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-)  (Same exercise required for other archs.)
Default compilation has optimisation - or else use ./configure --enable-debug

02543bad1c o Actually read snapshot percentage from the kernel - what a pain! :)
o Not sure if the code in dev_manager is really optimal, but it works..
   will look at adjusting it a bit now.
 o I *think* it works right when one snapshot if full but others aren't,
   but I haven't really been able to test it because the full snapshot
   somehow resets itself and weird things start happening to the system...

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

8d3afaa53c More use of LV locking. 2002-03-01 19:08:11 +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?

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

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.

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

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.
