Online JFS

Raj_58 — Thu, 30 Sep 2004 11:18:27 GMT

Hi,
I installed Online JFS and i mirrored the bootdisk.I booted from the mirror disk.When i try to extend the filesystem size , it's not working. It's giving the following error...

" Logical volume /dev/vg00/lvol5 is currently mounted on /opt and could not be unmounted. The LV cannot be extended until the file system is able to be unmounted. Note that the fuser(1M) command can be used outside of SAM to help determine what processes and users are currently accessing this file system. "

Any suggestions ?

Thanks

What coomand are you running?

Should be:

lvextend -L /dev/vg00/lvol5
fsadm -b M /opt

Try it from the command line. Also makesure OnlineJFS product filesets are in configured state

# swlist -l fileset -a state OnlineJFS

Also check for the vxadv drive int he kernel

# strings /stand/vmunix | grep vxadv

Now try to extend the LV

# lvextend -L /dev/vg00/lvolname

# fsadm -F vxfs -b m /opt

Hi Sundar adn geoff,

I was trying in SAM and i couldnt succeed.
When i tried now with
lvextend -L 1600 /dev/vg00/lvol5
it's working. But

# fsadm -F vxfs -b 1600m /opt command gives error
fsadm: the -b option requires "HP OnLineJFS (Advanced Vxfs)"
gives error

any suggestions for this?

Sounds like OnlineJFS isn't installed/active - check Sundars commands above.

Things to check--
(for fsadm -b to work)

1. swlist -a state -l fileset OnlineJFS
2. /sbin/fs/vxfs/vxenablef -a
3. Is vxadv driver in kernel
kmsystem|grep vxadv

# swlist -l bundle | grep -i JFS
B3929BA B.11.00 HP OnLineJFS (Advanced VxFS)
# swlist -l fileset -a state B3929BA
# B3929BA
# B3929BA.AdvJournalFS
B3929BA.AdvJournalFS.AJFS-ENG-A-MAN configured
B3929BA.AdvJournalFS.AJFS-JPN-E-MAN configured
B3929BA.AdvJournalFS.AJFS-JPN-S-MAN configured
B3929BA.AdvJournalFS.VXFS-ADV-KRN configured
B3929BA.AdvJournalFS.VXFS-ADV-RUN configured

If you gave above installed and configured. You should be successful to do fsadm -b also.

Just do

# fsadm -b
fsadm: argument missing for the option b

If this is like above then you are only missing correct parameters in your command.

Just check above first.

Thanks

What do you get with:

vxlicense -p

That just checks your license...

Should look like:

vrts:vxlicense: INFO: Feature name: HP_OnlineJFS [50]
vrts:vxlicense: INFO: Number of licenses: 1 (non-floating)
vrts:vxlicense: INFO: Expiration date: Sun Jun 24 02:00:00 2007 (996.5 days from now)
vrts:vxlicense: INFO: Release Level: 22
vrts:vxlicense: INFO: Machine Class: All
vrts:vxlicense: INFO: Site ID: 0

If not, you may have to re-install OnlineJFS...

If you want you can use extendfs also in single user mode.

Just as curiosity, you would like to check the space availeble in your VG where your are trying to extend the FS. I believe you are in root VG.

You can use following if you are going to do it in single user mode when /opt is not mounted.

extendfs -F vxfs -s size /dev/vg00/lvol5

-s size Specifies the number of DEV_BSIZE blocks to be added to the file system. If size is not specified, the maximum possible size is used.

you may shutdown all applications.
fuser -ku /dev/vg00/lvol5

then u

umount /dev/vg00/lvol5
extendfs as mentioned above.
mount
start all applications...

Hope this helps
Prashant

<<< the="" -b="" option="" requires="">gives error >>>sounds like your online JFS is not active/configured properly.
Try #swlist -l fileset -a state OnlineJFS
check the status of the OnlineJFS,
use swconfig command to reconfigure it.
