174f5a3a49 Add sparse devices: lvcreate -s --virtualoriginsize (hidden zero origin).
Add lvs origin_size field.
Fix linux configure --enable-debug to exclude -O2.

Still a few rough edges, but hopefully usable now:
  lvcreate -s vg1 -L 100M --virtualoriginsize 1T

31709134c9 Enable use of cached metadata for pvs & pvdisplay.
Currently PV commands, which performs full device scan, repeatly
re-reads PVs and scans for all devices.

This behaviour can lead to OOM for large VG.

This patch allows using internal metadata cache for pvs & pvdisplay,
so the commands scan the PVs only once.
(We have to use VG_GLOBAL otherwise cache is invalidated on every
VG unlock in process_single PV call.)

b49362420c Add --dataalignment to pvcreate to specify alignment of data area. (mbroz)
This patch is not fully tested and leaves some related bugs unfixed.

Intended behaviour of the code now:

  pe_start in the lvm2 format PV label header is set only by pvcreate (or
vgconvert -M2) and then preserved in *all* operations thereafter.

  In some specialist cases, after the PV is added to a VG, the pe_start
field in the VG metadata may hold a different value and if so, it
overrides the other one for as long as the PV is in such a VG.

  Currently, the field storing the size of the data area in the PV label
header always holds 0.  As it only has meaning in the context of a
volume group, it is calculated whenever the PV is added to a VG (and can
be derived from extent_size and pe_count in the VG metadata).

295019815e - change new log_ARG variable to more explicit mirrorlog_ARG. 2007-08-09 21:25:08 +00:00
Jonathan Earl Brassow
6d696706be This patch changes the arguments that specify the mirror
log type.  Previously, we had a '--corelog' argument that
would change the default type from 'disk' to 'core'.  I
think that creates too much confusion - especially when
doing conversions on mirrors.

The new argument '--log' takes either "disk" or "core"
as a parameter.  This could be expanded in the future
for additional logging types as well.

Examples:
# Creating a 2-way mirror
$> lvcreate -m1 ... # implicitly use default disk logging
$> lvcreate -m1 --log disk ... # explicit disk logging
$> lvcreate -m1 --log core ... # specify core logging
$> lvcreate -m1 --corelog ... # old way still works

# Conversion examples
$> lvconvert --log core ... # convert to core logging
$> lvconvert --log disk ... # convert to disk logging
$> lvconvert -mX --corelog ... # old way still works
$> lvconvert -mX ... # old way of converting to disk logging still works

Changes are reflected in the man pages.
