File System problem(Abnormal output)

Tirtha — Mon, 25 May 2009 04:24:31 GMT

Hi Friends,
One problem in file system..

The output of #bdf command is shown bellow

Filesystem kbytes used avail %used Mounted on
/dev/root 6160384 321768 5793048 5% /
/dev/vg00/lvol7 10240000 2638040 7542696 26% /usr

/dev/vg01/lvol2 25600000 13716960 11140372 55% /u01old

Please look at the 1st line.
It should be like that

Filesystem kbytes used avail %used Mounted on
/dev/vgoo/lvol2 6160384 321768 5793048 5% /

/dev/vg01/lvol2 25600000 13716960 11140372 55% /u01old

How can I change this???

Hi,

remove mount table /etc/mnttab and recreate it by mount -a. This will fix it.

Hi,

There is a problem with your /etc/mnttab you can delete /etc/mnttab and recreate with "mount -a"

Hi Tirtha,

Have you tried the solution given above? Or still you are facing the same issue?

You can check if the entries are normal in fstab specially for root. You can also compare it with your different servers.

Regds,

In fstab everything is ok..

when you issue this command ;
# ll /dev/root
brw-r----- 1 bin sys 255 0xffffff May 7 16:07 /dev/root

can you see this ?

and when you edit /etc/fstab and /etc/mnttab ,they are similar or not ?

the "/dev/root" address is inside the fstab or mnttab ??

and besides, none of the suggestions works, recommend "reboot" your server

Hi Tirtha,

Always allow the system to restart after booting into maintanance mode. If system is booted directly from maintanance mode to normal mode /dev/root will be mounted as / like in your output.

This should be fixed by running these sequence of commands.
# vgchange -a y /dev/vg00
# mv /etc/mnttab /etc/mnttab.old
# mount -a

If the above doesn't work, you may have to reboot the server.
