425 | Some bug fixes & minor enhancements, including: | |

427 | Missing man pages written. | |
428 | Tool error codes made more consistent. | |

430 | O_DIRECT can be turned off if it doesn't work in your kernel. | |
b2bb7264 | 431 | dumpconfig to display the active configuration file |
f74d51d9 AK |
432 | |
433 | You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'. | |
434 | If your root filesystem is on an LV, you should run one of those two | |
435 | commands to fix up the special files in /dev in your real root filesystem | |
436 | after finishing with your initrd. Also, remember you can use | |
437 | 'vgchange --ignorelockingfailure' on your initrd if the tool fails because | |
438 | it can't write a lock file to a read-only filesystem. | |

440 | Wednesday 30th April 2003 |
441 | ========================= | |
442 | A pvmove implementation is now available for the new metadata format. | |
443 | ||
444 | When running a command that allocates space (e.g. lvcreate), you can now | |
445 | restrict not only which disk(s) may be used but also the Physical Extents | |
446 | on those disks. e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000 | |
447 | ||
448 | ||
449 | Monday 18th November 2002 | |
5a52dca9 AK |
450 | ======================== |
451 | ||
452 | The new format of LVM metadata is ready for you to test! | |
453 | We expect it to be more efficient and more robust than the original format. | |
454 | It's more compact and supports transactional changes and replication. | |
455 | Should things go wrong on a system, it's human-readable (and editable). | |
456 | ||
457 | Please report any problems you find to the mailing list, | |
458 | linux-lvm@sistina.com. The software has NOT yet been thoroughly | |
459 | tested and so quite possibly there'll still be some bugs in it. | |
460 | Be aware of the disclaimer in the COPYING file. | |
461 | ||
462 | While testing, we recommend turning logging on in the configuration file | |
463 | to provide us with diagnostic information: | |
464 | log { | |
465 | file="/tmp/lvm2.log" | |
541f8753 | 466 | level=7 |
5518374b | 467 | activation=1 |
5a52dca9 AK |
468 | } |
469 | ||
470 | You should schedule regular backups of your configuration file and | |
471 | metadata backups and archives (normally kept under /etc/lvm). | |
472 | ||
473 | Please read docs/example.conf and "man lvm.conf" to find out more about | |
474 | the configuration file. | |
475 | ||
476 | To convert an existing volume group called vg1 to the new format using | |
477 | the default settings, use "vgconvert -M2 vg1". See "man vgconvert". | |
478 | ||
479 | -M (or --metadatatype in its long form) is a new flag to indicate which | |
480 | format of metadata the command should use for anything it creates. | |
481 | Currently, the valid types are "lvm1" and "lvm2" and they can be | |
482 | abbreviated to "1" and "2" respectively. The default value for this | |
483 | flag can be changed in the global section in the config file. | |
484 | ||
485 | Backwards-compatible support for the original LVM1 metadata format is | |
486 | maintained, but it can be moved into a shared library or removed | |
487 | completely with configure's --with-lvm1 option. | |
488 | ||
489 | Under LVM2, the basic unit of metadata is the volume group. Different | |
490 | volume groups can use different formats of metadata - vg1 could use | |
491 | the original LVM1 format while vg2 used the new format - but you can't | |
492 | mix formats within a volume group. So to add a PV to an LVM2-format | |
493 | volume group you must run "pvcreate -M2" on it, followed by "vgextend". | |
494 | ||
495 | With LVM2-format metadata, lvextend will let you specify striping | |
496 | parameters. So an LV could consist of two or more "segments" - the | |
497 | first segment could have 3 stripes while the second segment has just 2. | |
498 | ||
499 | LVM2 maintains a backup of the current metadata for each volume group | |
500 | in /etc/lvm/backup, and puts copies of previous versions in | |
501 | /etc/lvm/archive. "vgcfgbackup" and "vgcfgrestore" can be used to | |
502 | create and restore from these files. If you fully understand what | |
503 | you're doing, metadata can be changed by editing a copy of a current | |
504 | backup file and using vgcfgrestore to reload it. | |
505 | ||
506 | Please read the pvcreate man page for more information on the new | |
507 | format for metadata. | |
508 | ||
509 | All tools that can change things have a --test flag which can be used | |
510 | to check the effect of a set of cmdline args without really making the | |
511 | changes. | |
512 | ||
513 | ||
514 | What's not finished? | |
515 | ==================== | |
516 | The internal cache. If you turn on debugging output you'll see lots of | |
914c9723 | 517 | repeated messages, many of which will eventually get optimised out. |
5a52dca9 AK |
518 | |
519 | --test sometimes causes a command to fail (e.g. vgconvert --test) even | |
520 | though the real command would work: again, fixing this is waiting for | |
521 | the work on the cache. | |
522 | ||
523 | Several of the tools do not yet contain the logic to handle full | |
524 | recovery: combinations of pvcreate and vgcfgrestore may sometimes be | |
525 | needed to restore metadata if a tool gets interrupted or crashes or | |
526 | finds something unexpected. This applies particularly to tools that | |
527 | work on more than one volume group at once (e.g. vgsplit). | |
528 | ||
529 | Display output. Some metadata information cannot yet be displayed. | |
5a52dca9 AK |
530 | |
531 | Recovery tools to salvage "lost" metadata directly from the disks: | |
532 | but we hope the new format will mean such tools are hardly ever needed! | |
533 |
