1、問題復現方法

1.  systemctl stop udisks2

關閉原本的udisks2服務。

2.  valgrind --tool=memcheck --leak-check=full --show-reachable=yes --track-origins=yes --log-file=/root/valgrind.log -v /usr/libexec/udisks2/udisksd

利用valgrind運行udisksd進程2分鐘或更久。

3.  運行期間手動執行mkfs.ext4 /dev/sdb、mount /dev/sdb /root/test、umount /root/test等命令。

打開/root/valgrind.log文件, 有如下結果:
