* thin: use discards as plural rather than singularAlasdair G Kergon2012-08-071-1/+1
| | | | Global change from --discard to --discards, as that feels more natural.
* args: increase major:minor limit to 4095:1048575Peter Rajnoha2012-08-061-0/+2
| | | | | | | | | Remove the limit for major and minor number arguments used while specifying persistent numbers via -My --major <major> --minor <minor> option which was set to 255 before. Follow the kernel limit instead which is 12 bits for major and 20 bits for minor number (kernel >= 2.6 and LVM formats that does not have FMT_RESTRICTED_LVIDS - so still keep the old limit of 255 for lvm1 format).
* thin: add discard support for thin poolZdenek Kabelac2012-07-181-0/+1
| | | | | | | | Add arg support for discard. Add discard ignore, nopassdown, passdown (=default) support. Flags could be set per pool. lvcreate [--discard {ignore|no_passdown|passdown}] vg/thinlv
* activate: add autoactivation hooksPeter Rajnoha2012-06-281-0/+3
| | | | | | | | | | | | | | | | Define an 'activation_handler' that gets called automatically on PV appearance/disappearance while processing the lvmetad_pv_found and lvmetad_pv_gone functions that are supposed to update the lvmetad state based on PV availability state. For now, the actual support is for PV appearance only, leaving room for PV disappearance support as well (which is a more complex problem to solve as this needs to count with possible device stack). Add a new activation change mode - CHANGE_AAY exposed as '--activate ay/-aay' argument ('activate automatically'). Factor out the vgchange activation functionality for use in other tools (like pvscan...).
* args: add --activate synonym for --available argPeter Rajnoha2012-06-281-1/+1
| | | | | | | | We're refererring to 'activation' all over the code and we're talking about 'LVs being activated' all the time so let's use 'activation/activate' everywhere for clarity and consistency (still providing the old 'available' keyword as a synonym for backward compatibility with existing environments).
* Fix a regression in handling --major/--minor arguments to lvcreate & lvchange,Petr Rockai2012-03-161-0/+1
| | | | by allowing arg_int_value to be used with groupable options.
* Switch pvscan --cache major:minor to --major --minor.Alasdair Kergon2012-03-061-0/+1

* The lvmetad client-side integration. Only active when use_lvmetad = 1 is set inPetr Rockai2012-02-231-0/+1
| | | | lvm.conf *and* lvmetad is running.
* Support rounding of percentage upwardZdenek Kabelac2012-01-051-1/+1
| | | | | | | | | | | | | | | We want to keep this logic - when LV is extend - extend the LV by at least given amount, when LV is reduced - reduce the LV by at most given amount. So for this the rounding needs to be used. Current logic which seems to satisfy give rule is to round up all extent values for LV resize upward except for values with '-' sign that are round downward. This patch also fixes the problem when lvextend --use-polices tried to extend LV the by i.e. 20% - but the resulting 20% were smaller the extent size thus before this patch no extension happened.

* Support repetition of --addtag and --deltag arguments.Alasdair Kergon2010-11-111-28/+40

* Fix --[vg]metadatacopies arg processingAlasdair Kergon2010-06-301-2/+1

* Allow 'all' and 'unmanaged' values for --vgmetadatacopies.Dave Wysochanski2010-06-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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>
* Use "" instead of <> for configure.h and libdevmapper.hZdenek Kabelac2010-06-151-2/+2

* Remove no-longer-used arg_ptr_value.Alasdair Kergon2010-04-291-1/+1
| | | | Fix -M and --type to use strings not pointers that change on config refresh.
* Add %ORIGIN support to lv{create,extend,reduce,resize} --extents optionMike Snitzer2010-02-031-1/+2
| | | | | | | | | | | Allow the number of logical extents to be expressed (for a snapshot) as a percentage of the total space in the Origin Logical Volume with the suffix %ORIGIN. Update the relevant man pages accordingly. Eliminate inconsistencies between the man pages and tools/commands.h Signed-off-by: Mike Snitzer <snitzer@redhat.com>
* Tidy some uses of arg_count and introduce arg_is_set.Alasdair Kergon2009-11-031-1/+2

* Fix convert polling to ignore LV with different UUID.Milan Broz2009-06-011-1/+1
| | | | | | | | | | | | | | | | | | | When mirror convert polling is started (mainly as backgound process, in lvchange -a y or in lvconvert itself) it tries to read VG and LV identified by its name. Unfortunatelly, the VG can have already different LV under the same name, and various more or less funny things can happen (note that _finish_lvconvert_mirror suspends the volume for example). (the typical example is our testing script which continuously recreates LVs under the same name in the same VG.) This patch adds optional uuid parameter which helps to properly select the monitoring object. For lvconvert polling it is set to LV UUID and both _get_lvconvert_vg and _get_lvconvert_lv uses it to read proper VG/LV. (In the pvmove case it is NULL, here we poll for physical volume name).
