①、badblocks -s -w /dev/sda END START (END代表需要修复的扇区末端,START代表需要修复的扇区起始端) ②、fsck -a /dev/sda 修复后再用badblocks -s -v -o /root/bb.log /dev/sda监测看是否还有坏道存在,如果坏道还是存在的话说明坏道属于硬盘坏道。硬盘坏道要用隔离方法,首先记录监测出的硬盘坏道然后分...

Rather than sending a single descriptor to the device for each request, we send a chain of three: 原因很简单。我们希望能够读写数据,而无需来回复制。如果数据嵌入到 virtio_blk_req 结构中,那么当我们要向文件系统或应用程序发送数据时,就必须将数据复制出来。因此,我们要利用 virtqueues 允许我们连锁描述...
