2362Some bug fixes & minor enhancements, including:
2363 Backwards compatibility with LVM1 metadata improved.
2364 Missing man pages written.
2365 Tool error codes made more consistent.
2366 vgmknodes written.
2367 O_DIRECT can be turned off if it doesn't work in your kernel.

2370You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2371If your root filesystem is on an LV, you should run one of those two
57015b12 2372commands to fix up the special files in /dev in your real root filesystem
f74d51d9
AK
2373after finishing with your initrd. Also, remember you can use
2374'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2375it can't write a lock file to a read-only filesystem.

2378=========================
2379A pvmove implementation is now available for the new metadata format.
2380
2381When running a command that allocates space (e.g. lvcreate), you can now
57015b12 2382restrict not only which disk(s) may be used but also the Physical Extents
541f8753
AK
2383on those disks. e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000

AK
2387========================
2388
2389The new format of LVM metadata is ready for you to test!
2390 We expect it to be more efficient and more robust than the original format.
2391 It's more compact and supports transactional changes and replication.
2392 Should things go wrong on a system, it's human-readable (and editable).
2393
57015b12 2394Please report any problems you find to the mailing list,
5a52dca9
AK
2395linux-lvm@sistina.com. The software has NOT yet been thoroughly
2396tested and so quite possibly there'll still be some bugs in it.
2397Be aware of the disclaimer in the COPYING file.
2398
57015b12 2399While testing, we recommend turning logging on in the configuration file
5a52dca9
AK
2400to provide us with diagnostic information:
2401 log {
2402 file="/tmp/lvm2.log"
541f8753 2403 level=7
5518374b 2404 activation=1
5a52dca9
AK
2405 }
2406
2407You should schedule regular backups of your configuration file and
2408metadata backups and archives (normally kept under /etc/lvm).
2409
57015b12 2410Please read docs/example.conf and "man lvm.conf" to find out more about
5a52dca9
AK
2411the configuration file.
2412
2413To convert an existing volume group called vg1 to the new format using
2414the default settings, use "vgconvert -M2 vg1". See "man vgconvert".
2415
2416-M (or --metadatatype in its long form) is a new flag to indicate which
2417format of metadata the command should use for anything it creates.
2418Currently, the valid types are "lvm1" and "lvm2" and they can be
2419abbreviated to "1" and "2" respectively. The default value for this
2420flag can be changed in the global section in the config file.
2421
2422Backwards-compatible support for the original LVM1 metadata format is
2423maintained, but it can be moved into a shared library or removed
2424completely with configure's --with-lvm1 option.
2425
2426Under LVM2, the basic unit of metadata is the volume group. Different
2427volume groups can use different formats of metadata - vg1 could use
2428the original LVM1 format while vg2 used the new format - but you can't
2429mix formats within a volume group. So to add a PV to an LVM2-format
2430volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2431
2432With LVM2-format metadata, lvextend will let you specify striping
2433parameters. So an LV could consist of two or more "segments" - the
2434first segment could have 3 stripes while the second segment has just 2.
2435
2436LVM2 maintains a backup of the current metadata for each volume group
2437in /etc/lvm/backup, and puts copies of previous versions in
2438/etc/lvm/archive. "vgcfgbackup" and "vgcfgrestore" can be used to
57015b12 2439create and restore from these files. If you fully understand what
5a52dca9
AK
2440you're doing, metadata can be changed by editing a copy of a current
2441backup file and using vgcfgrestore to reload it.
2442
2443Please read the pvcreate man page for more information on the new
2444format for metadata.
2445
2446All tools that can change things have a --test flag which can be used
2447to check the effect of a set of cmdline args without really making the
2448changes.
2449
2450
2451What's not finished?
2452====================
2453The internal cache. If you turn on debugging output you'll see lots of
914c9723 2454repeated messages, many of which will eventually get optimised out.
5a52dca9 2455
57015b12

2456--test sometimes causes a command to fail (e.g. vgconvert --test) even
2457though the real command would work: again, fixing this is waiting for
5a52dca9
AK
2458the work on the cache.
2459
2460Several of the tools do not yet contain the logic to handle full
2461recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2462needed to restore metadata if a tool gets interrupted or crashes or
2463finds something unexpected. This applies particularly to tools that
2464work on more than one volume group at once (e.g. vgsplit).
2465
2466Display output. Some metadata information cannot yet be displayed.
5a52dca9
AK
2467
2468Recovery tools to salvage "lost" metadata directly from the disks:
2469but we hope the new format will mean such tools are hardly ever needed!
