umout and extend file ststem

[Grayh]

i have done a lvextend

then when i try umount i get

# umount /dev/vg00/lvol6
umount: cannot unmount /opt : Device busy
umount: return error 1.
# fuser -u /dev/vg00/lvol6
/dev/vg00/lvol6: 5976m(root) 5984mt(root) 6031mt(sfmdb) 5981mt(root
) 5982mt(root) 6032mt(sfmdb) 6005mt(sfmdb) 6002mt(sfmdb) 5983mt(r
oot) 5974mt(root) 6006mt(sfmdb)

How can i now umount lvol6 and do extendfs

[John Guster · Accepted solution]

fuser -k /dev/vg00/lvol6, then extendfs. Assume you don't have onlineJFS installed.

[Torsten.]

It's most likely better to boot into single user mode for doing this. I assume you don't have onlineJFS.

[Grayh]

but by doing that might reboot the server...

will it

# extendfs /dev/vg00/lvol6
vxfs extendfs: /dev/vg00/lvol6 is mounted, cannot extend.

Hi:

If you don't have Online JFS (and you should!) then you can't use 'fsadm' to resize a filesystem without unmounting it.

If this is the case, you must unmount the filesystem in order to 'extendfs' it. For most 'vg00' filesystems it is easiest if you *boot into* single user-mode where only the root filesystem is mounted. Use the commands in '/sbin' or in your specific case, mount '/usr' if that isn't the filesystem you are attempting to extend.

It is cleanest, when done, to simply reboot again and resume normal production.

Regards!

make sure there are no processes attatched to this volume after fuser -k. then umount /dev/vg00/lvol6, then extendfs.

[Grayh]

Hooo... no....

By mistake I have run fuser -k on lvol6 without going into single suer mode


and now I cannot ping to the servers... how ever I can login through MP>Co

lvol7 is mounted on /usr

cat kill it still says busy

then extendfs

Hi (again):

Since you are going deeper and deeper, do yourself a favor and REBOOT into SINGLE USER MODE as I suggested.

...JRF...

[Grayh]

yes Now I am into single user mode james...

[Grayh]

I am in single user mode

I was able to do this on lvol6 ie., /opt but I can't do it for /usr

# fuser -k /dev/vg00/lvol7
/dev/vg00/lvol7: 0mKilled
# umount /dev/vg00/lvol7
umount: cannot unmount /usr : Device busy
umount: return error 1.
#

[Ivan Krastev]

Check with fuser (or lsof) what is preventing /usr from umount. have you tried:
#fuser -ku /usr

regards,
ivan

[Grayh]

# umount /usr
umount: cannot unmount /usr : Device busy
umount: return error 1.
# fuser -ku /usr
/usr:

# umount /usr
umount: cannot unmount /usr : Device busy
umount: return error 1.

Hi (again);

> I am in single user mode ... I was able to do this on lvol6 ie., /opt but I can't do it for /usr

Then you aren't in single user mode or you mounted '/usr' after booting. You *don't* need to do this. You should interrupt the boot; interract with the IPL; and specify boot 'hpux -s'. If you do this, then only the root filesystem will be mounted. Then, use the commands in '/sbin' as I noted.

Regards!

don't be panic, make sure one step a time, do again. Single user mood has nothing started yet.

Hi (again):

I urge you to slow down and then sit down and read:

http://docs.hp.com/en/B2355-90950/index.html

Chapter-5 discusses booting and startup.

Chapter-6 discusses disk and filesystem management.

Regards!
