vdo: add lvs fields to query vdo volume properties Add lots of vdo fields: vdo_operating_mode - For vdo pools, its current operating mode. vdo_compression_state - For vdo pools, whether compression is running. vdo_index_state - For vdo pools, state of index for deduplication. vdo_used_size - For vdo pools, currently used space. vdo_saving_percent - For vdo pools, percentage of saved space. vdo_compression - Set for compressed LV (vdopool). vdo_deduplication - Set for deduplicated LV (vdopool). vdo_use_metadata_hints - Use REQ_SYNC for writes (vdopool). vdo_minimum_io_size - Minimum acceptable IO size (vdopool). vdo_block_map_cache_size - Allocated caching size (vdopool). vdo_block_map_era_length - Speed of cache writes (vdopool). vdo_use_sparse_index - Sparse indexing (vdopool). vdo_index_memory_size - Allocated indexing memory (vdopool). vdo_slab_size - Increment size for growing (vdopool). vdo_ack_threads - Acknowledging threads (vdopool). vdo_bio_threads - IO submitting threads (vdopool). vdo_bio_rotation - IO enqueue (vdopool). vdo_cpu_threads - CPU threads for compression and hashing (vdopool). vdo_hash_zone_threads - Threads for subdivide parts (vdopool). vdo_logical_threads - Logical threads for subdivide parts (vdopool). vdo_physical_threads - Physical threads for subdivide parts (vdopool). vdo_max_discard - Maximum discard size volume can recieve (vdopool). vdo_write_policy - Specified write policy (vdopool). vdo_header_size - Header size at front of vdopool. Previously only 'lvdisplay -m' was exposing them.

Remove explicit double quotes from columns.h 'id' entries. The 'id' entries in columns.h are the report field names. Since these are unique, we'd like to use them in generation of 'get' / 'set' functions. As a step towards using them for this purpose, remove the explicit double quotes and use the macro '#' character to add the double quotes back when placing them into the '_fields' array 'id' member.

Add lv_layout_and_type fn, lv_layout and lv_type reporting fields. The lv_layout and lv_type fields together help with LV identification. We can do basic identification using the lv_attr field which provides very condensed view. In contrast to that, the new lv_layout and lv_type fields provide more detialed information on exact layout and type used for LVs. For top-level LVs which are pure types not combined with any other LV types, the lv_layout value is equal to lv_type value. For non-top-level LVs which may be combined with other types, the lv_layout describes the underlying layout used, while the lv_type describes the use/type/usage of the LV. These two new fields are both string lists so selection (-S/--select) criteria can be defined using the list operators easily: [] for strict matching {} for subset matching. For example, let's consider this: $ lvs -a -o name,vg_name,lv_attr,layout,type LV VG Attr Layout Type [lvol1_pmspare] vg ewi------- linear metadata,pool,spare pool vg twi-a-tz-- pool,thin pool,thin [pool_tdata] vg rwi-aor--- level10,raid data,pool,thin [pool_tdata_rimage_0] vg iwi-aor--- linear image,raid [pool_tdata_rimage_1] vg iwi-aor--- linear image,raid [pool_tdata_rimage_2] vg iwi-aor--- linear image,raid [pool_tdata_rimage_3] vg iwi-aor--- linear image,raid [pool_tdata_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_1] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_2] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_3] vg ewi-aor--- linear metadata,raid [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin [pool_tmeta_rimage_0] vg iwi-aor--- linear image,raid [pool_tmeta_rimage_1] vg iwi-aor--- linear image,raid [pool_tmeta_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tmeta_rmeta_1] vg ewi-aor--- linear metadata,raid thin_snap1 vg Vwi---tz-k thin snapshot,thin thin_snap2 vg Vwi---tz-k thin snapshot,thin thin_vol1 vg Vwi-a-tz-- thin thin thin_vol2 vg Vwi-a-tz-- thin multiple,origin,thin Which is a situation with thin pool, thin volumes and thin snapshots. We can see internal 'pool_tdata' volume that makes up thin pool has actually a level10 raid layout and the internal 'pool_tmeta' has level1 raid layout. Also, we can see that 'thin_snap1' and 'thin_snap2' are both thin snapshots while 'thin_vol1' is thin origin (having multiple snapshots). Such reporting scheme provides much better base for selection criteria in addition to providing more detailed information, for example: $ lvs -a -o name,vg_name,lv_attr,layout,type -S 'type=metadata' LV VG Attr Layout Type [lvol1_pmspare] vg ewi------- linear metadata,pool,spare [pool_tdata_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_1] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_2] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_3] vg ewi-aor--- linear metadata,raid [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin [pool_tmeta_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tmeta_rmeta_1] vg ewi-aor--- linear metadata,raid (selected all LVs which are related to metadata of any type) lvs -a -o name,vg_name,lv_attr,layout,type -S 'type={metadata,thin}' LV VG Attr Layout Type [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin (selected all LVs which hold metadata related to thin) lvs -a -o name,vg_name,lv_attr,layout,type -S 'type={thin,snapshot}' LV VG Attr Layout Type thin_snap1 vg Vwi---tz-k thin snapshot,thin thin_snap2 vg Vwi---tz-k thin snapshot,thin (selected all LVs which are thin snapshots) lvs -a -o name,vg_name,lv_attr,layout,type -S 'layout=raid' LV VG Attr Layout Type [pool_tdata] vg rwi-aor--- level10,raid data,pool,thin [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin (selected all LVs with raid layout, any raid layout) lvs -a -o name,vg_name,lv_attr,layout,type -S 'layout={raid,level1}' LV VG Attr Layout Type [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin (selected all LVs with raid level1 layout exactly) And so on...

This patch is not a final state, rather a transitional step. It should not be giving more 'worst' values then previous many-ioctl-calls-per-lv solution.

Components of field names are generally separated by underscores (which are optional at run-time). (Dropped 3 duplicate fields now covered by this rule.)

lvconvert: add new reporting fields for reshaping During an ongoing reshape, the MD kernel runtime reads stripes relative to data_offset and starts storing the reshaped stripes (with new raid layout and/or new stripesize and/or new number of stripes) relative to new_data_offset. This is to avoid writing over any data in place which is non-atomic by nature and thus be recoverable without data loss in the transition. MD uses the term out-of-place reshaping for it. There's 2 other areas we don't have report capability for: - number of data stripes vs. total stripes (e.g. raid6 with 7 stripes toal has 5 data stripes) - number of (rotating) parity/syndrome chunks (e.g. raid6 with 7 stripes toal has 2 parity chunks; one per stripe for P-Syndrome and another one for Q-Syndrome) Thus, add the following reportable keys: - reshape_len (in current units) - reshape_len_le (in logical extents) - data_offset (in sectors) - new_data_offset ( " ) - data_stripes - parity_chunks Enhance lvchange-raid.sh, lvconvert-raid-reshape-linear_to_striped.sh, lvconvert-raid-reshape-striped_to_linear.sh, lvconvert-raid-reshape.sh and lvconvert-raid-takeover.sh to make use of new keys.
