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
The "status" field is treated as it ever has been, unknown flags there are
treated as fatal metadata errors. However, in the "flags" field, any unknown
flags will be ignored and silently dropped. This improves
backward-compatibility possibilities. (Any versions without support for this
new "flag" field will drop the field altogether, which is same as ignoring all
the flags there.)
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
allocation policy. This can currently take one of three values:
typedef enum {
ALLOC_NEXT_FREE,
ALLOC_STRICT,
ALLOC_CONTIGUOUS
} alloc_policy_t;
Notice that 'SIMPLE' has turned into the slightly more meaningful NEXT_FREE.
ii) Put code into display.[hc] for converting one of these enums to a
text representation and back again.
ii) Updated the text format so this also has the alloc_policy field.
Lots of changes/very little testing so far => there'll be bugs!
Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files. Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.
Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).
e.g. metadata {
dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}
Plenty of refinements still in the pipeline.
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
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.
