zero device.

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

50762c2186 agk, I recall you saying you had a massive commit pending; if you need me
to back this out so you can do that commit, let me know.  Also, if there's
an issue with the error message that's displayed, just change it in tools.h.

This causes a "device-mapper driver/module not loaded?" error message to
be displayed for the commands that require dm-mod, if the tools can't get
the driver version.  It's not done for commands that don't require dm-mod.
This should clear up some problems people have had attempting to use lvm2
without rtfm'ing.

fdf8038fe5 Improved snapshot-related arg validation 2002-07-17 16:04:05 +00:00

7cc602c800 i) Add the VISIBLE flag to the text format. (Other changes are pending
for lib/activate.)

097d49e73d i) There's now a seperate field in struct logical_volume that stores the
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.

25b733809a Merge with text format branch.
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.

8573c6bcac Snapshots are now attached to their origin device for locking purposes
so lock the origin instead of the snapshot itself when creating one.

eea1d6932c o Top level device is now just called <vg>-<lv> (there's no 'top'
layer appended).

o  Got rid of the unused layer->type field and enum.
2002-03-07 15:29:31 +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.)

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?

o Reset all parameters before use in lvcreate.
