mount -o remount, rw /
重新掛載根分區(qū)試試,

作者: city224 時間: 2013-04-26 12:25
提示:
[root@localhost ~]# mount -o remount, rw /
mount: you must specify the filesystem type

作者: zhaopingzi 時間: 2013-04-26 12:38
那就加上-t ext3試試

作者: city224 時間: 2013-04-26 13:22
提示:
[root@localhost ~]# mount -t ext3 -o remount, rw /
mount: block device rw is write-protected, mounting read-only

看你的root分區(qū)，比如root是 /dev/sda6

那就看下hdparm /dev/sda6 看readonly tag是0／1

手動設(shè)定 hdparm -r 0 /dev/sda6

try

作者: to407 時間: 2013-04-26 14:05
如果這個有效，記得完事了備份數(shù)據(jù)準(zhǔn)備換存儲

作者: city224 時間: 2013-04-26 15:20
本身就是0
[root@localhost /]# hdparm /dev/mapper/VolGroup00-LogVol00

/dev/mapper/VolGroup00-LogVol00:
readonly = 0 (off)
readahead = 256 (on)
geometry = 0/0/0, sectors = 565313536, start = 0

要的是再下層的硬件。/dev/sd* 之類。如果還正常的話就不是硬件問題

作者: 大致若魚 時間: 2013-04-27 12:27
lsattr /etc/mtab
看看有沒有t屬性，如果有，通過chattr更改屬性再試試。

我和你遇到的問題一樣，
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.

/dev/root / ext3 ro,data=ordered 0 0

上次出現(xiàn)過去一次，機(jī)器重啟起不來，到一個修復(fù)界面，在修復(fù)界面來來回回調(diào)了很多東西，后來好了，今天又出現(xiàn)，你是怎么解決的呢？

作者: leiminhaha 時間: 2015-10-13 11:21
回復(fù) 15# y君臨城下

試一下 fsck -y 然后再重啟下機(jī)器。
