fccc39a3a7 o Added function find_snapshots to snapshot_manip.c that returns a list 
of snapshots whose origin is the lv passed in.
 o Used this new function to make lvdisplay properly display all snapshots
   attached to a origin.

b9923fe3f2 Make lvm2 compile on big endian archs; use the kernel/glibc's endian 
conversion stuff, instead of implementing our own.  Tested on a little
endian system (x86); I'll let the debian handle big endian testing.  :)

b7749b7a96 o Will now correctly remove expired achive files from the system when 
archive_vg is called.
 o Added a #define to the top of the file - not sure if this is the
   appropriate place for it though

6e2ff7fb35 o Updated *display output for LVM1 compatibility 
o There is still a bit missing
   + all are missing the {PV,VG,LV} # - that is not applicable in LVM2
   + pvdisplay doesn't show how many LVs are contained on it
   + much of the snapshot information isn't available for lvdisplay
 o Look at the code for other potiential FIXMEs  :)

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.

f31c47ade8 o Perform a BLKFLSBUF ioctl whenever a block device is closed. 
Patrick, can you see if this fixes your cluster syncing problem please ?
If so I'll make it so it only syncs if you have actually written to the
device.

323a167b49 o dm->active_list now filled in, ATM this is based on the layer name rather 
than the uuid.
 2002-03-11 11:27:48 +00:00
Joe Thornber
fd6932b18b o Comment out some new code that was preventing pjc activating 
snapshots.  This will go back in when the active_list is working.

4526747997 o Add active_list to dev_manager 
o  Origin layer is only added to snapshots if a snapshot is in the

0fe3a2c512 o Add comment describing what we're aiming for with dev_manager. 
o  Remove dev_manager_reactivate, since it'll be the same as activate.

o  Merge the mark, visible and dirty fields into the same flags field.
 2002-03-07 16:48:46 +00:00
Joe Thornber
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.)

is why lvremove of snapshots wasn't working.

f4cbeaf0ac o Lock mechanism for LV activation 
o #defines for common lock flag combinations

de6c918392 o Removed old files 
o  rewrote activate.c to use dev-manager, I'm sure these two will merge
   at some point.

o  Rename is broken ATM

o  dev-manager puts the calls through to fs.c for layers that have the
   'visible' flag set.

a45f546fe0 o Use 'pvcreate --setphysicalvolumesize' with no short form (instead of -s) 
and add severe warning if it's used to make a device seem bigger than
  it really is.  This is not an option people should be using as it
  breaks metadata integrity.

294ddff8a6 o snapshot support for the text format.

Joe Thornber
7d68b08028 o First changes to add snapshot support. 
I'm taking a different route from LVM1 here in that snapshots are a
seperate entity from the logical volumes, I think of them as an
application of an LV (or two lvs rather).  As such there is a list of
snapshots held against the vg, and there is *not* a SNAPSHOT, or
SHAPSHOT_ORG flag in lv->status.

59d6420b9a o I decided that the archive_format shouldn't really be a format at 
all since it only supports vg_write.  It has been replaced with:

int archive_vg(struct volume_group *vg,
	       const char *dir,
	       const char *desc,
	       uint32_t retain_days,
	       uint32_t min_archive);

which is now called directly by tools/archive.c
 2002-02-08 11:58:18 +00:00
Joe Thornber
e74999af51 o Add cmd_line field to struct cmd_context 
o  Text format now has a description and time field at the top level.

o  archiving and backup set the description appropriately. eg,

   for an archive:

     description = "Created *before* executing 'lvextend test_vg/lvol0 -l +1'."
     creation_time = 1013166332

   for a backup:

     description = "Created *after* executing 'lvextend test_vg/lvol0 -l +1'."
     creation_time = 1013166332

This is preparing the way for a simple vgcfgundo command.

812c699c8d Basic support for persistent minor numbers; 
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

Alasdair Kergon
b849de1d18 Fix the device cache to cope reasonably safely with device name changes. 
This should be a rare occurrence so the aim is to recover if it's
straightforward to do so, otherwise just to abort the operation.
If people *knowingly* change device names, they should always run vgscan
afterwards.

A few bytes of memory gets leaked inside a pool each time an alias
has to be discarded - it's not worth restructuring the code to reuse it.

More of LVM2 needs updating to pass device objects (or uuids) about
instead of pathnames so that resolution of pathname->object only happens
once per operation.

dev_cache_get() should now always return the *current* device at the path given

dev_name_confirmed() replaces dev_name() whenever it's important to
know that name for the device is still current (ie when opening it).
If the cache doesn't know a current name, the function fails.

dev_open() guarantees that the file descriptor returned is for the dev_t
of the device structure it was passed.

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.
