2309 Friday 14th November 2003
2310 =========================
2311 Some bug fixes & minor enhancements, including:
2312 Backwards compatibility with LVM1 metadata improved.
2313 Missing man pages written.
2314 Tool error codes made more consistent.
2316 O_DIRECT can be turned off if it doesn't work in your kernel.
2317 dumpconfig to display the active configuration file
2319 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2320 If your root filesystem is on an LV, you should run one of those two
2321 commands to fix up the special files in /dev in your real root filesystem
2322 after finishing with your initrd. Also, remember you can use
2323 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2324 it can't write a lock file to a read-only filesystem.
2326 Wednesday 30th April 2003
2327 =========================
2328 A pvmove implementation is now available for the new metadata format.
2330 When running a command that allocates space (e.g. lvcreate), you can now
2331 restrict not only which disk(s) may be used but also the Physical Extents
2332 on those disks. e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2335 Monday 18th November 2002
2336 ========================
2338 The new format of LVM metadata is ready for you to test!
2339 We expect it to be more efficient and more robust than the original format.
2340 It's more compact and supports transactional changes and replication.
2341 Should things go wrong on a system, it's human-readable (and editable).
2343 Please report any problems you find to the mailing list,
2344 linux-lvm@sistina.com. The software has NOT yet been thoroughly
2345 tested and so quite possibly there'll still be some bugs in it.
2346 Be aware of the disclaimer in the COPYING file.
2348 While testing, we recommend turning logging on in the configuration file
2349 to provide us with diagnostic information:
2351 file="/tmp/lvm2.log"
2356 You should schedule regular backups of your configuration file and
2357 metadata backups and archives (normally kept under /etc/lvm).
2359 Please read docs/example.conf and "man lvm.conf" to find out more about
2360 the configuration file.
2362 To convert an existing volume group called vg1 to the new format using
2363 the default settings, use "vgconvert -M2 vg1". See "man vgconvert".
2365 -M (or --metadatatype in its long form) is a new flag to indicate which
2366 format of metadata the command should use for anything it creates.
2367 Currently, the valid types are "lvm1" and "lvm2" and they can be
2368 abbreviated to "1" and "2" respectively. The default value for this
2369 flag can be changed in the global section in the config file.
2371 Backwards-compatible support for the original LVM1 metadata format is
2372 maintained, but it can be moved into a shared library or removed
2373 completely with configure's --with-lvm1 option.
2375 Under LVM2, the basic unit of metadata is the volume group. Different
2376 volume groups can use different formats of metadata - vg1 could use
2377 the original LVM1 format while vg2 used the new format - but you can't
2378 mix formats within a volume group. So to add a PV to an LVM2-format
2379 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2381 With LVM2-format metadata, lvextend will let you specify striping
2382 parameters. So an LV could consist of two or more "segments" - the
2383 first segment could have 3 stripes while the second segment has just 2.
2385 LVM2 maintains a backup of the current metadata for each volume group
2386 in /etc/lvm/backup, and puts copies of previous versions in
2387 /etc/lvm/archive. "vgcfgbackup" and "vgcfgrestore" can be used to
2388 create and restore from these files. If you fully understand what
2389 you're doing, metadata can be changed by editing a copy of a current
2390 backup file and using vgcfgrestore to reload it.
2392 Please read the pvcreate man page for more information on the new
2393 format for metadata.
2395 All tools that can change things have a --test flag which can be used
2396 to check the effect of a set of cmdline args without really making the
2400 What's not finished?
2401 ====================
2402 The internal cache. If you turn on debugging output you'll see lots of
2403 repeated messages, many of which will eventually get optimised out.
2405 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2406 though the real command would work: again, fixing this is waiting for
2407 the work on the cache.
2409 Several of the tools do not yet contain the logic to handle full
2410 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2411 needed to restore metadata if a tool gets interrupted or crashes or
2412 finds something unexpected. This applies particularly to tools that
2413 work on more than one volume group at once (e.g. vgsplit).
2415 Display output. Some metadata information cannot yet be displayed.
2417 Recovery tools to salvage "lost" metadata directly from the disks:
2418 but we hope the new format will mean such tools are hardly ever needed!
