https://bugzilla.kernel.org/show_bug.cgi?id=186551 --- Comment #4 from Eric Sandeen <sandeen@xxxxxxxxxxx> --- I am pretty sure all of those messages will be in 512-byte sectors. /proc/partitions is in 1k units (just to keep it interesting) 781412184 * 1024/512 = 1562824368 512-byte sectors - also past the sector it's trying to discard. I wonder what happens if you try a blkdiscard for the entire device, and see if you get a failure from it as well. (*** note that this will clear any data on the device, as it will discard every block on the device ***). It seems unlikely that this is an ext4/e2fsprogs problem at this point. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
