Question

我的beaglebone上的MySQL无法启动按照以下步骤后我会遇到问题：
我想提取eMMC的内容以保存和重用。
我使用/opt/scripts/tools/eMMC/beaglebone-black-make-microSD-flasher-from-eMMC.sh将板载eMMC中的图像写入microSD卡。
（点击此链接http://elinux.org/BeagleBone_Black_Extracting_eMMC_contents#Sources）
我的microSD卡（16Gb）
我收到了这个错误

rsync: recv_generator: mkdir "/tmp/rootfs/var/www" failed: No space left on device (28)
*** Skipping any contents from this failed directory ***

sent 11164596708 bytes  received 13752725 bytes  1434501.05 bytes/sec
total size is 13493412445  speedup is 1.21
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1070) [sender=3.0.9]
writing to [/dev/mmcblk0] failed...
-----------------------------
umount: /dev/mmcblk0p1: not mounted

在那之后，所有的beagblebone光都是明亮的。
MySQL从这个错误开始：

Starting mysql (via systemctl): mysql.serviceJob failed. See system journal and 'systemctl status' for details.
 failed!

看起来磁盘空间是个问题吗？

Tomcat服务器正常启动。

更新：

这是使用 systemd-journalctl -a cmd时的日志：

Jan 03 06:49:17 beaglebone mysqld[9443]: 170103  6:49:17 [Warning] Using unique option prefix key_buffer instead of key_buffer_size is deprecated and will be removed in
Jan 03 06:49:17 beaglebone mysqld[9443]: /usr/sbin/mysqld: Error on realpath() on '/var/lib/mysql-files' (Error 2)

我的问题是什么？。

Answer 1

After see logs: I think my problem is missing folder.
I just create new '/var/lib/mysql-files'
MySQL is started.

为什么MySQL在beaglebone black上将eMMC的内容提取到microSD后无法启动？
