RAID: Add scrubbing support for RAID LVs New options to 'lvchange' allow users to scrub their RAID LVs. Synopsis: lvchange --syncaction {check|repair} vg/raid_lv RAID scrubbing is the process of reading all the data and parity blocks in an array and checking to see whether they are coherent. 'lvchange' can now initaite the two scrubbing operations: "check" and "repair". "check" will go over the array and recored the number of discrepancies but not repair them. "repair" will correct the discrepancies as it finds them. 'lvchange --syncaction repair vg/raid_lv' is not to be confused with 'lvconvert --repair vg/raid_lv'. The former initiates a background synchronization operation on the array, while the latter is designed to repair/replace failed devices in a mirror or RAID logical volume. Additional reporting has been added for 'lvs' to support the new operations. Two new printable fields (which are not printed by default) have been added: "syncaction" and "mismatches". These can be accessed using the '-o' option to 'lvs', like: lvs -o +syncaction,mismatches vg/lv "syncaction" will print the current synchronization operation that the RAID volume is performing. It can be one of the following: - idle: All sync operations complete (doing nothing) - resync: Initializing an array or recovering after a machine failure - recover: Replacing a device in the array - check: Looking for array inconsistencies - repair: Looking for and repairing inconsistencies The "mismatches" field with print the number of descrepancies found during a check or repair operation. The 'Cpy%Sync' field already available to 'lvs' will print the progress of any of the above syncactions, including check and repair. Finally, the lv_attr field has changed to accomadate the scrubbing operations as well. The role of the 'p'artial character in the lv_attr report field as expanded. "Partial" is really an indicator for the health of a logical volume and it makes sense to extend this include other health indicators as well, specifically: 'm'ismatches: Indicates that there are discrepancies in a RAID LV. This character is shown after a scrubbing operation has detected that portions of the RAID are not coherent. 'r'efresh : Indicates that a device in a RAID array has suffered a failure and the kernel regards it as failed - even though LVM can read the device label and considers the device to be ok. The LV should be 'r'efreshed to notify the kernel that the device is now available, or the device should be 'r'eplaced if it is suspected of failing.

RAID: Add writemostly/writebehind support for RAID1 'lvchange' is used to alter a RAID 1 logical volume's write-mostly and write-behind characteristics. The '--writemostly' parameter takes a PV as an argument with an optional trailing character to specify whether to set ('y'), unset ('n'), or toggle ('t') the value. If no trailing character is given, it will set the flag. Synopsis: lvchange [--writemostly <PV>:{t|y|n}] [--writebehind <count>] vg/lv Example: lvchange --writemostly /dev/sdb1:y --writebehind 512 vg/raid1_lv The last character in the 'lv_attr' field is used to show whether a device has the WriteMostly flag set. It is signified with a 'w'. If the device has failed, the 'p'artial flag has priority. Example ("nosync" raid1 with mismatch_cnt and writemostly): [~]# lvs -a --segment vg LV VG Attr #Str Type SSize raid1 vg Rwi---r-m 2 raid1 500.00m [raid1_rimage_0] vg Iwi---r-- 1 linear 500.00m [raid1_rimage_1] vg Iwi---r-w 1 linear 500.00m [raid1_rmeta_0] vg ewi---r-- 1 linear 4.00m [raid1_rmeta_1] vg ewi---r-- 1 linear 4.00m Example (raid1 with mismatch_cnt, writemostly - but failed drive): [~]# lvs -a --segment vg LV VG Attr #Str Type SSize raid1 vg rwi---r-p 2 raid1 500.00m [raid1_rimage_0] vg Iwi---r-- 1 linear 500.00m [raid1_rimage_1] vg Iwi---r-p 1 linear 500.00m [raid1_rmeta_0] vg ewi---r-- 1 linear 4.00m [raid1_rmeta_1] vg ewi---r-p 1 linear 4.00m A new reportable field has been added for writebehind as well. If write-behind has not been set or the LV is not RAID1, the field will be blank. Example (writebehind is set): [~]# lvs -a -o name,attr,writebehind vg LV Attr WBehind lv rwi-a-r-- 512 [lv_rimage_0] iwi-aor-w [lv_rimage_1] iwi-aor-- [lv_rmeta_0] ewi-aor-- [lv_rmeta_1] ewi-aor-- Example (writebehind is not set): [~]# lvs -a -o name,attr,writebehind vg LV Attr WBehind lv rwi-a-r-- [lv_rimage_0] iwi-aor-w [lv_rimage_1] iwi-aor-- [lv_rmeta_0] ewi-aor-- [lv_rmeta_1] ewi-aor--

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...

lvm2app: Add signed numerical property values Currently lvm2app properties have the following structure: typedef struct lvm_property_value { uint32_t is_settable:1; uint32_t is_string:1; uint32_t is_integer:1; uint32_t is_valid:1; uint32_t padding:28; union { const char *string; uint64_t integer; } value; } lvm_property_value_t; which assumes that numerical values were in the range of 0 to 2**64-1. However, some of the properties were 'signed', like LV major/minor numbers and some reserved values for properties that represent percentages. Thus when the values were retrieved they were in two's complement notation. So for a -1 major number the API user would get a value of 18446744073709551615. The API user could cast the returned value to an int64_t to handle this, but that requires the API developer to look at the source code and determine when it should be done. This change modifies the return property structure to: typedef struct lvm_property_value { uint32_t is_settable:1; uint32_t is_string:1; uint32_t is_integer:1; uint32_t is_valid:1; uint32_t is_signed:1; uint32_t padding:27; union { const char *string; uint64_t integer; int64_t signed_integer; } value; } lvm_property_value_t; With this addition the API user can interrogate that the value is numerical, (is_integer = 1) and subsequently check if it's signed (is_signed = 1) too. If signed, then the API developer should use the union's signed_integer to avoid casting. This change maintains backwards compatibility as the structure size remains unchanged and integer value remains unchanged. Only the additional bit taken from the pad is utilized.
