David Teigland d9e8895a96 Allow dm-integrity to be used for raid images ... dm-integrity stores checksums of the data written to an LV, and returns an error if data read from the LV does not match the previously saved checksum. When used on raid images, dm-raid will correct the error by reading the block from another image, and the device user sees no error. The integrity metadata (checksums) are stored on an internal LV allocated by lvm for each linear image. The internal LV is allocated on the same PV as the image. Create a raid LV with an integrity layer over each raid image (for raid levels 1,4,5,6,10): lvcreate --type raidN --raidintegrity y [options] Add an integrity layer to images of an existing raid LV: lvconvert --raidintegrity y LV Remove the integrity layer from images of a raid LV: lvconvert --raidintegrity n LV Settings Use --raidintegritymode journal|bitmap (journal is default) to configure the method used by dm-integrity to ensure crash consistency. Initialization When integrity is added to an LV, the kernel needs to initialize the integrity metadata/checksums for all blocks in the LV. The data corruption checking performed by dm-integrity will only operate on areas of the LV that are already initialized. The progress of integrity initialization is reported by the "syncpercent" LV reporting field (and under the Cpy%Sync lvs column.) Example: create a raid1 LV with integrity: $ lvcreate --type raid1 -m1 --raidintegrity y -n rr -L1G foo Creating integrity metadata LV rr_rimage_0_imeta with size 12.00 MiB. Logical volume "rr_rimage_0_imeta" created. Creating integrity metadata LV rr_rimage_1_imeta with size 12.00 MiB. Logical volume "rr_rimage_1_imeta" created. Logical volume "rr" created. $ lvs -a foo LV VG Attr LSize Origin Cpy%Sync rr foo rwi-a-r--- 1.00g 4.93 [rr_rimage_0] foo gwi-aor--- 1.00g [rr_rimage_0_iorig] 41.02 [rr_rimage_0_imeta] foo ewi-ao---- 12.00m [rr_rimage_0_iorig] foo -wi-ao---- 1.00g [rr_rimage_1] foo gwi-aor--- 1.00g [rr_rimage_1_iorig] 39.45 [rr_rimage_1_imeta] foo ewi-ao---- 12.00m [rr_rimage_1_iorig] foo -wi-ao---- 1.00g [rr_rmeta_0] foo ewi-aor--- 4.00m [rr_rmeta_1] foo ewi-aor--- 4.00m		2020-04-15 12:10:32 -05:00
