I messed up sectors vs. bytes. Would your fix (commit d0eb20a863ba7dc) address this BZ too? https://bugzilla.redhat.com/show_bug.cgi?id=1314687 Seems not, I think that BZ may be due to the LBPRZ clause in commit 397737223 ("sd: Make discard granularity match logical block size when LBPRZ=1") ? should be: q->limits.discard_granularity = 1 * logical_block_size; Mike -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
