5389 commands to fix up the special files in /dev in your real root filesystem
5390 after finishing with your initrd. Also, remember you can use

5398 When running a command that allocates space (e.g. lvcreate), you can now
5399 restrict not only which disk(s) may be used but also the Physical Extents
5400 on those disks. e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000

5404 ========================
5406 The new format of LVM metadata is ready for you to test!
5407 We expect it to be more efficient and more robust than the original format.
5408 It's more compact and supports transactional changes and replication.
5409 Should things go wrong on a system, it's human-readable (and editable).
5411 Please report any problems you find to the mailing list,
5412 linux-lvm@sistina.com. The software has NOT yet been thoroughly
5413 tested and so quite possibly there'll still be some bugs in it.
5414 Be aware of the disclaimer in the COPYING file.
5416 While testing, we recommend turning logging on in the configuration file
5417 to provide us with diagnostic information:
5419 file="/tmp/lvm2.log"
5424 You should schedule regular backups of your configuration file and
5425 metadata backups and archives (normally kept under /etc/lvm).
5427 Please read docs/example.conf and "man lvm.conf" to find out more about
5428 the configuration file.
5430 To convert an existing volume group called vg1 to the new format using
5431 the default settings, use "vgconvert -M2 vg1". See "man vgconvert".
5433 -M (or --metadatatype in its long form) is a new flag to indicate which
5434 format of metadata the command should use for anything it creates.
5435 Currently, the valid types are "lvm1" and "lvm2" and they can be
5436 abbreviated to "1" and "2" respectively. The default value for this
5437 flag can be changed in the global section in the config file.
5439 Backwards-compatible support for the original LVM1 metadata format is
5440 maintained, but it can be moved into a shared library or removed
5441 completely with configure's --with-lvm1 option.
5443 Under LVM2, the basic unit of metadata is the volume group. Different
5444 volume groups can use different formats of metadata - vg1 could use
5445 the original LVM1 format while vg2 used the new format - but you can't
5446 mix formats within a volume group. So to add a PV to an LVM2-format
5447 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
5449 With LVM2-format metadata, lvextend will let you specify striping
5450 parameters. So an LV could consist of two or more "segments" - the
5451 first segment could have 3 stripes while the second segment has just 2.
5453 LVM2 maintains a backup of the current metadata for each volume group
5454 in /etc/lvm/backup, and puts copies of previous versions in
5455 /etc/lvm/archive. "vgcfgbackup" and "vgcfgrestore" can be used to
5456 create and restore from these files. If you fully understand what
5457 you're doing, metadata can be changed by editing a copy of a current
5458 backup file and using vgcfgrestore to reload it.
5460 Please read the pvcreate man page for more information on the new
5461 format for metadata.
5463 All tools that can change things have a --test flag which can be used
5464 to check the effect of a set of cmdline args without really making the
5468 What's not finished?
5469 ====================
5470 The internal cache. If you turn on debugging output you'll see lots of
5471 repeated messages, many of which will eventually get optimised out.
5473 --test sometimes causes a command to fail (e.g. vgconvert --test) even
5474 though the real command would work: again, fixing this is waiting for
5475 the work on the cache.
5477 Several of the tools do not yet contain the logic to handle full
5478 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
5479 needed to restore metadata if a tool gets interrupted or crashes or
5480 finds something unexpected. This applies particularly to tools that
5481 work on more than one volume group at once (e.g. vgsplit).
5483 Display output. Some metadata information cannot yet be displayed.
5485 Recovery tools to salvage "lost" metadata directly from the disks:
5486 but we hope the new format will mean such tools are hardly ever needed!
