mount -l 挂载信息的errors

[7猫.]

ubuntu:~$ mount -l
/dev/sda1 on / type ext4 (rw,errors=remount-ro)//请问 这里什么意思？
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)

(rw,errors=remount-ro)//请问 这里什么意思？

这是挂载选项，不是错误信息
意为：若出错，则以 ro(read-only) 模式重新挂载

errors={continue|remount-ro|panic}
Define the behavior when an error is encountered. (Either ignore
errors and just mark the filesystem erroneous and continue, or
remount the filesystem read-only, or panic and halt the system.)
The default is set in the filesystem superblock, and can be changed
using tune2fs(8).
