Hi

ONLINEJFS is not installed. i try to make " lvextend" command, and the result is ok. but when i umount filesystem, i have the error message below:
umount: cannot find /usr in /etc/mmttab
cannot umount /usr

------------------------------------
plesae help me!!

[F Verschuren]

This can work:
create a new mntab by:
# mv /etc/mnttab /etc/mnttab.old
# mountall

umount /usr

if this does not work please post:
bdf |grep usr
and the /etc/mnttab

[kacou]

In single user mode? or multi user mode?

[F Verschuren]

the move you can do in single and multy user mode, if the umount gives the same error in multy user mode the problem is not fixed, proerly you will get the error that there are proceses running here (like ksh)
so whitout single user mode, you can not do the umount....

Hi,

please post contents of /etc/mnttab.

Anyway, whether you have /usr mounted, I doubt you could umount it at run level 3. That is the great matter that OnlineJFS has.

Boot in single user mode and issue

extendfs -F vxfs /dev/vg00/lvol7

Then try to mount all filesystems by

mount -a

and finally

init 3

HTH.

Best regards,
Fabio

Are you already in single user mode?

/usr may be not mounted yet - check with "mount" and proceed.

[Tim Nelson]

Must be in single user mode to unmount /usr.

If you booted to single user mode then /usr will not be mounted only /, that is what single-user mode is about.

execute your extendfs then reboot or init3

Hi kacou

Best is to boot system in single user mode and extend it.
