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

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.

f2f2634990 o vgcfgrestore works ! (with the couple of examples I tried). 2002-01-15 17:37:23 +00:00

6036e5e0f7 o split the uuid -> device map out from vgcache 
o  roll vgcache back to agk's implementation, we'll revisit this as part
   of the cluster integration.

o  change the extra_info field in a label to be a void *

fc63d04f42 o Moved the current label.[hc] sideways to lvm2_label.[hc] 
o  First pass at low level labelling switch.  This allows us to
   register different label types (eg, lvm1, lvm2).

8cdf0a831c Wipe the first label if writing the second one failed. 2001-12-18 14:39:32 +00:00

515df8784a Write the location of both labels in the labels so we can check them. I don't do 
much with this ATM (apart from check that they all match up).
Use a different CRC routine.

75f7aa5563 made the hard-coded 512 into BLOCK_SIZE just for neatness sake. 
log_error() if writing the label fails so someone knows which was in error.

8a51c23765 Use a proper CRC calculation. 2001-12-12 09:05:44 +00:00

f4a7ce7c49 - Change label format to include a string disk_type and a version number. 
- The iterator can find labels by string and also appropriate version number (==,
  <= or any) if you want.
- Add labels_match() call that compares the two labels and returns an error if
  they do not match.
- Write labels in sector 1 & last rather than 2 & last as per Joe.
