| |
| Friday 14th November 2003 |
| ========================= |

| Backwards compatibility with LVM1 metadata improved. |
| Missing man pages written. |
| Tool error codes made more consistent. |
| vgmknodes written. |
| O_DIRECT can be turned off if it doesn't work in your kernel. |
| dumpconfig to display the active configuration file |
| |
| You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'. |
| If your root filesystem is on an LV, you should run one of those two |
| commands to fix up the special files in /dev in your real root filesystem |
| after finishing with your initrd. Also, remember you can use |
| 'vgchange --ignorelockingfailure' on your initrd if the tool fails because |
| it can't write a lock file to a read-only filesystem. |
| |
| Wednesday 30th April 2003 |
| ========================= |
| A pvmove implementation is now available for the new metadata format. |
| |
| When running a command that allocates space (e.g. lvcreate), you can now |
| restrict not only which disk(s) may be used but also the Physical Extents |
| on those disks. e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000 |
| |
| |
| Monday 18th November 2002 |
| ======================== |
| |
| The new format of LVM metadata is ready for you to test! |
| We expect it to be more efficient and more robust than the original format. |
| It's more compact and supports transactional changes and replication. |
| Should things go wrong on a system, it's human-readable (and editable). |
| |
| Please report any problems you find to the mailing list, |
| [email protected]. The software has NOT yet been thoroughly |
| tested and so quite possibly there'll still be some bugs in it. |
| Be aware of the disclaimer in the COPYING file. |
| |
| While testing, we recommend turning logging on in the configuration file |
| to provide us with diagnostic information: |
| log { |
| file="/tmp/lvm2.log" |
| level=7 |
| activation=1 |
| } |
| |
| You should schedule regular backups of your configuration file and |
| metadata backups and archives (normally kept under /etc/lvm). |
| |
| Please read docs/example.conf and "man lvm.conf" to find out more about |
| the configuration file. |
| |
| To convert an existing volume group called vg1 to the new format using |
| the default settings, use "vgconvert -M2 vg1". See "man vgconvert". |
| |
| -M (or --metadatatype in its long form) is a new flag to indicate which |
| format of metadata the command should use for anything it creates. |
| Currently, the valid types are "lvm1" and "lvm2" and they can be |
| abbreviated to "1" and "2" respectively. The default value for this |
| flag can be changed in the global section in the config file. |
| |
| Backwards-compatible support for the original LVM1 metadata format is |
| maintained, but it can be moved into a shared library or removed |
| completely with configure's --with-lvm1 option. |
| |
| Under LVM2, the basic unit of metadata is the volume group. Different |
| volume groups can use different formats of metadata - vg1 could use |
| the original LVM1 format while vg2 used the new format - but you can't |
| mix formats within a volume group. So to add a PV to an LVM2-format |
| volume group you must run "pvcreate -M2" on it, followed by "vgextend". |
| |
| With LVM2-format metadata, lvextend will let you specify striping |
| parameters. So an LV could consist of two or more "segments" - the |
| first segment could have 3 stripes while the second segment has just 2. |
| |
| LVM2 maintains a backup of the current metadata for each volume group |
| in /etc/lvm/backup, and puts copies of previous versions in |
| /etc/lvm/archive. "vgcfgbackup" and "vgcfgrestore" can be used to |
| create and restore from these files. If you fully understand what |
| you're doing, metadata can be changed by editing a copy of a current |
| backup file and using vgcfgrestore to reload it. |
| |
| Please read the pvcreate man page for more information on the new |
| format for metadata. |
| |
| All tools that can change things have a --test flag which can be used |
| to check the effect of a set of cmdline args without really making the |
| changes. |
| |
| |
| What's not finished? |
| ==================== |
| The internal cache. If you turn on debugging output you'll see lots of |
| repeated messages, many of which will eventually get optimised out. |
| |
| --test sometimes causes a command to fail (e.g. vgconvert --test) even |
| though the real command would work: again, fixing this is waiting for |
| the work on the cache. |
| |
| Several of the tools do not yet contain the logic to handle full |
| recovery: combinations of pvcreate and vgcfgrestore may sometimes be |
| needed to restore metadata if a tool gets interrupted or crashes or |
| finds something unexpected. This applies particularly to tools that |
| work on more than one volume group at once (e.g. vgsplit). |
| |
| Display output. Some metadata information cannot yet be displayed. |
| |
| Recovery tools to salvage "lost" metadata directly from the disks: |
| but we hope the new format will mean such tools are hardly ever needed! |
