I had another look at the argument processing code: o You must list long args with no short option (eg. --version) at the front of the args.h file. o If an argument has no short option, set the short option in args.h to '\0' o The index into the 'the_args' var is now stored as the option value for getopt, iff there is no short opt.

Add --pvmetadatacopies as a synonym for --metadatacopies in various commands. Going forward, we would like to allow users to specify the total number of metadatacopies in a VG rather than on a per-PV basis. In order to facilitate that, introduce --pvmetadatacopes to replace --metadatacopies everywhere. We still allow --metadatacopies for pv commands, but require --pvmetadatacopies for vg commands. Eventually we will introduce --vgmetadatacopies. Once we do that, we should either deprecate --metadatacopies or make it a synonym based on the command (pvmetadatacopies for pv commands, and vgmetadatacopies for vg commands). The latter option would likely just require a simple 'strncpy' check against cmd->command->name to qualify the merge_synonym call. Update nightly tests to cover the pvmetadatacopies synonym. Note that this patch is the result of an eariler review comment for the implicit pvcreate patches. Should apply cleanly on top of the implicit pvcreate patches (I applied after patch 10/10 in that series). NOTE: This patch will require --pvmetadatacopies for vgconvert as --metadatacopies is no longer accepted.

Allow 'all' and 'unmanaged' values for --vgmetadatacopies. Allowing an 'all' and 'unmanaged' value is more intuitive, and provides a simple way for users to get back to original LVM behavior of metadata written to all PVs in the volume group. If the user requests "--vgmetadatacopies unmanaged", this instructs LVM not to manage the ignore bits to achieve a specific number of metadata copies in the volume group. The user is free to use "pvchange --metadataignore" to control the mdas on a per-PV basis. If the user requests "--vgmetadatacopies all", this instructs LVM to do 2 things: 1) clear all ignore bits, and 2) set the "unmanaged" policy going forward. Internally, we use the special MAX_UINT32 value to indicate 'all'. This 'just' works since it's the largest value possible for the field and so all 'ignore' bits on all mdas in the VG will get cleared inside _vg_metadata_balance(). However, after we've called the _vg_metadata_balance function, we check for the special 'all' value, and if set, we write the "unmanaged" value into the metadata. As such, the 'all' value is never written to disk. Signed-off-by: Dave Wysochanski <dwysocha@redhat.com>

Add --metadataignore to pvchange, allowing for ignoring of metadata areas. This patch just modifies pvchange to call the underlying ignore functions for mdas. Ensure special cases do not reflect changes in metadata (PVs with 0 mdas, setting ignored when already ignored, clearing ignored when not ignored).

This patch adds the capability to split off a mirror legs. It is pretty much the same as reducing the number of mirror legs, but we just don't delete them afterwards. The following command line interface is enforced: prompt> lvconvert --splitmirror <n> -n <name> <VG>/<LV> where 'n' is the number of images to split off, and where 'name' is the name of the newly split off logical volume. If more than one leg is split off, a new mirror will be the result. The newly split off mirror will have a 'core' log. Example: [root@bp-01 LVM2]# !lvs lvs -a -o name,copy_percent,devices LV Copy% Devices lv 100.00 lv_mimage_0(0),lv_mimage_1(0),lv_mimage_2(0),lv_mimage_3(0) [lv_mimage_0] /dev/sdb1(0) [lv_mimage_1] /dev/sdc1(0) [lv_mimage_2] /dev/sdd1(0) [lv_mimage_3] /dev/sde1(0) [lv_mlog] /dev/sdi1(0) [root@bp-01 LVM2]# lvconvert --splitmirrors 2 --name split vg/lv /dev/sd[ce]1 Logical volume lv converted. [root@bp-01 LVM2]# !lvs lvs -a -o name,copy_percent,devices LV Copy% Devices lv 100.00 lv_mimage_0(0),lv_mimage_2(0) [lv_mimage_0] /dev/sdb1(0) [lv_mimage_2] /dev/sdd1(0) [lv_mlog] /dev/sdi1(0) split 100.00 split_mimage_0(0),split_mimage_1(0) [split_mimage_0] /dev/sde1(0) [split_mimage_1] /dev/sdc1(0) It can be seen that '--splitmirror <n>' is exactly the same as '--mirrors -<n>' (note the minus sign), except there is the additional notion to keep the image being detached from the mirror instead of just throwing it away.

Add --dataalignment to pvcreate to specify alignment of data area. (mbroz) This patch is not fully tested and leaves some related bugs unfixed. Intended behaviour of the code now: pe_start in the lvm2 format PV label header is set only by pvcreate (or vgconvert -M2) and then preserved in *all* operations thereafter. In some specialist cases, after the PV is added to a VG, the pe_start field in the VG metadata may hold a different value and if so, it overrides the other one for as long as the PV is in such a VG. Currently, the field storing the size of the data area in the PV label header always holds 0. As it only has meaning in the context of a volume group, it is calculated whenever the PV is added to a VG (and can be derived from extent_size and pe_count in the VG metadata).

Add a [--poll {y|n}] flag to vgchange and lvchange to control whether the background polldaemon is allowed to start. It can be used standalone or in conjunction with --refresh or --available y. Control over when the background polldaemon starts will be particularly important for snapshot-merge of a root filesystem. Dracut will be updated to activate all LVs with: --poll n The lvm2-monitor initscript will start polling with: --poll y NOTE: Because we currently have no way of knowing if a background polldaemon is active for a given LV the following limitations exist and have been deemed acceptable: 1) it is not possible to stop an active polldaemon; so the lvm2-monitor initscript doesn't stop running polldaemon(s) 2) redundant polldaemon instances will be started for all specified LVs if vgchange or lvchange are repeatedly used with '--poll y' Signed-off-by: Mike Snitzer <snitzer@redhat.com>
