5ca6698f12 Add lv_is_active() to determine whether an lv is active.
Handles non-clustered as well as clustered.  For clustered,
the best we can do is try exclusive local activation.  If this
succeeds, we know it is not active elsewhere in the cluster.
Otherwise, we assume it is active elsewhere.

Alasdair Kergon
a9953411a8 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.

8ef2b021ed 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

1951dba955 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...

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

8c013da41f More use of LV locking. 2002-03-01 19:08:11 +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?

413cc9189e Begin conversion so LV id is passed to activation unit instead of
struct logical_volume.
2002-02-25 12:56:16 +00:00

14a81c5a03 Remove lv_update_write_access: use lv_reactivate directly now instead. 2002-02-20 21:28:22 +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
Joe Thornber
fdc7af232a 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.

Alasdair Kergon
4a624ca055 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.
