If a raid5/6 reshape is restarted (After stopping and re-assembling the array) and the array is marked read-only (or read-auto), then the reshape will appear to complete immediately, without actually moving anything around. This can result in corruption. There are two patches which do much the same thing in different places. They are separate because one is an older bug and so can be applied to more -stable kernels. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIUAwUAU40KTDnsnt1WYoG5AQJcaA/1GkoZit6LqLjiIQmsK9Ci/4TI+sNqYaSB 9SleSjWt+bcNCRY4sS3Wv0H580LmkoRR24wdei+mukoFa+bpBBs6PodPMABAVsnL VxlnUX+P4Ef77s2zJ8B5wCY3ftmecaQL3TdZf10+hIITacXSp7JmsLJXm3DW+Jvq DZsxJRBEQfsz5obZAZXnvPAcTSkqMT4QQ13nIEmaYEz+AYVn6Tcf8xwDBOcZM4u9 Gdi6BHNaY6RjSU1gsVblPYmWQyqqdgCJ6UEV/KYyY9rtFyozkvJ0SDWcu/kRA74A uydN5U6iVqJatY9l9eK2tV7GQkN+o+MWIA0JocTRZe67ihE4tWxiLRn/7fZdLVsX TV6zYar0M/ZSn3XioGi4hQ0tWDPpq/aCzCAk5JQpywgBmoaMqqh8rttwdCkWvK6P TNnaVfo3r9AMJY8MVm8in/efEhY6jUa3q2oDqCEKjuL916v9ODsxXloqTlbEy2KC NrKNLCZA2subbzPa3T8u4aKRBzl0xSBSig8ecrufSpDC1I0G+Mbuc8wrDzjAnI3N +fbQCxxRR0akcleZrFZD67avOa5/DsQqWJbcW1D5VCekJoZcgdz5CGJz/bNl+0i6 bwrvNWi6q1X2P4Nt2BBhk771xzNiUlufsI0x7SFIJxpDiGlxINkluXvnEQKFSzhr uYSrvTCQwg== =cTEe -----END PGP SIGNATURE----- Merge tag 'md/3.15-fixes' of git://neil.brown.name/md Pull two md bugfixes from Neil Brown: "Two md bugfixes for possible corruption when restarting reshape If a raid5/6 reshape is restarted (After stopping and re-assembling the array) and the array is marked read-only (or read-auto), then the reshape will appear to complete immediately, without actually moving anything around.
