https://bugzilla.kernel.org/show_bug.cgi?id=86471 --- Comment #4 from Theodore Tso <tytso@xxxxxxx> --- Are you sure this is actually a problem? Could it just be that when mysqld shuts down, it's issuing a huge number of buffered writes which is just taking a long, long time to get written out to your eMMC device (which is typically very, *very* slow to handle writes). I had suggested using blktrace to see if I/O is going on. You could also try looking using iostat or the dstat program. If it's just that I/O is still happening, then things may be working normally --- just that eMMC might be a bad match with a high performance database workload. -- 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
