linux ioctl root权限,linux – lsattr：设备的不适当的ioctl在读取标志时

对于我们运行CentOS 6.0的

Linux服务器之一,如果我执行lsattr / home,我会得到类似的东西(以root身份)：

$lsattr /home

lsattr: Inappropriate ioctl for device While reading flags on /home/user

lsattr: Inappropriate ioctl for device While reading flags on /home/user

lsattr: Inappropriate ioctl for device While reading flags on /home/DIR

现在,我尝试用chattr改变一些东西

$chattr -R -i /home

chattr: Inappropriate ioctl for device while reading flags on /home

装载回报：

$mount

/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)

proc on /proc type proc (rw)

sysfs on /sys type sysfs (rw)

devpts on /dev/pts type devpts (rw,gid=5,mode=620)

/dev/sda3 on /boot type ext3 (rw)

tmpfs on /dev/shm type tmpfs (rw)

none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

nfsd on /proc/fs/nfsd type nfsd (rw)

我不知道如何解决这个问题.有人可以帮忙吗？
