幾台虛拟機需要重新開機,重新開機後連接配接不上,通過管理軟體看到
Your system appears to have shut down uncleanly
press Y within 1 seconds to force file system integrity check...
checking root filesystem
/contains a file system with errors,check forced.
/:
Unattached inode 813065
/:UNEXPECTED INCONSISTENCY;RUN FSCK MANUALLY.
(i.e.,without -a or -p options)
[FAILED]
*** An error occurred during the file system check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintenance
(or type Control-D to continue):
一開始按ctrl+d還是跳到這個頁面,在就是輸入root密碼,能進入系統,開始使用網上的方法修複系統。
fsck -y /dev/vda1
fsck -y /dev/vda3
重新開機系統後發現還是原來的問題,用df -Th檢視,/boot和新增的分區都沒有挂在上
# df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/vda3 ext4 42G 13G 27G 32% /
tmpfs tmpfs 1.9G 0 1.9G 0% /dev/shm
先把/重新挂載
mount -rw -o remount /
挂載boot
mount /dev/vda1 /boot
再去檢視/etc/fstab以前挂載過硬碟,發現後來還添加了一塊兒vdb
# cat /etc/fstab
UUID=fc9d60a8-e39b-4c20-8d24-8f7975e6f1d7 / ext4 defaults 1 1
UUID=e1de6afb-150c-407d-80ec-e2c03ebcd8dd /boot ext4 defaults 1 2
UUID=c6b62139-385b-4891-b9e2-15876655cce9 swap swap defaults 0 0
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
/dev/vdb1 /hadoopWs ext4 defaults,noatime 1 1
fdisk -l 發現并沒有新增加的磁盤。
解決辦法
chmod a+rw /etc/fstab
vim /etc/fstab
下面一行注釋掉
#/dev/vdb1 /hadoopWs ext4 defaults,noatime 1 1
