[root@work ~]# mount
/dev/sda5 on / type ext3 (rw)
proc on /proc type proc (rw)
mount: warning /etc/mtab is not writable (e.g. read-only filesystem).
It's possible that information reported by mount( is not
up to date. For actual information about system mount points
check the /proc/mounts file.
按照提示检查/proc/mounts,显示结果如下
[root@work ~]# cat /proc/mounts
rootfs / rootfs rw 0 0
/dev/root / ext3 ro,data=ordered 0 0 #这里是ro,问题可能就是在这里
