About extendfs

[SeaMark_1]

I want to extend one HFS filesystem.

root@xkbqd06# bdf
Filesystem kbytes used avail %used Mounted on
.....
/dev/vg00/bwdbackup
20036719 5532812 12500235 31% /bwdbackup

then,
umount /bwdbackup
lvextend -L 26000 /dev/vg00/bwdbackup
extendfs -F hfs /dev/vg00/rbwdbackup
mount /dev/vg00/bwdbackup /bwdbackup

In the end, execute bdf
the situation continues...
root@xkbqd06# bdf
Filesystem kbytes used avail %used Mounted on
.......
/dev/vg00/bwdbackup
20036719 5532812 12500235 31% /bwdbackup


each command executed successfully, so, I don't understand why "extendfs" do NOT take into effect.

All the best.

Your commands are correct but if you did not use "-s" option in extendfs, this command extend maximum as possible.
You sould do as:
umount /bwdbackup
lvextend -L 26000 /dev/vg00/bwdbackup
extendfs -F hfs -s 26000 /dev/vg00/rbwdbackup
mount /dev/vg00/bwdbackup /bwdbackup


Or you can still use fsadm to extend:
lvextend -L 26000 /dev/vg00/bwdbackup
fsadm -F vxfs -b 26000 /bwdbackup

hi, thanks a lot. :)
I do as you described but this problem still exists.

Look at the whole process:
----------------------------

df -k /bwdbackup/

mount /dev/vg00/test /bwdbackup

df -k /bwdbackup/
/bwdbackup (/dev/vg00/test ) : 100473 total allocated Kb
100464 free allocated Kb
9 used allocated Kb
0 % allocation used
-----------------------------

I guess the filesytem type,hfs,is the real reason which extendfs can't work properly, since I do this on Vxfs is no problem.

I need a patch indeed?

All the best.

1.have you try to use fsadm?
2. Check installed patches on your system and commpare with required patches (online JFS patches.).

hi,

a doubt.you are sure that you tried
extendfs -F hfs /dev/vg00/rbwdbackup

if you have tried (with out raw device)
extendfs -F hfs /dev/vg00/bwdbackup

this problem can occure.

regds,

[Saurav_1]

The Final output of BDF shows that the filesystem has not got extended.

remember this can be done even if /bwdbackup is mounted. Check the FREE PE in VG.
lvextend -L 26000 /dev/vg00/bwdbackup.

To extend the filesystem you have to unmount the filesystem.

cheers.

Hi,

could you post

fstyp -v /dev/vg00/bwdbackup

Hi SeaMark,

Strange :-(

Could you take a closer look at the extendfs command.

# whereis extendfs
# ll /sbin/extendfs
# ll /usr/sbin/extendfs
# file /sbin/extendfs
# file /usr/sbin/extendfs

Regards,
Robert-Jan

[SeaMark_1]

Reminding of I do these above on Vxfs is no problem !!

as you tell me, I do this:

root@xkbqd06# whereis extendfs
extendfs: /usr/sbin/extendfs /sbin/extendfs /usr/share/man/man1m.Z/extendfs.1m

root@xkbqd06# ll /usr/sbin/extendfs /sbin/extendfs
lrwxr-xr-x 1 root sys 16 Dec 5 21:31 /sbin/extendfs -> /sbin/fs_wrapper
lrwxr-xr-x 1 root bin 16 Dec 5 21:38 /usr/sbin/extendfs -> /sbin/fs_wrapper

root@xkbqd06# file /usr/sbin/extendfs
/usr/sbin/extendfs: ELF-32 executable object file - IA64
======================

It seems that it implys some other things.

You are running 11.23 right?

Try installing the following patches

PHCO_31635 s700_800 11.23 Cumulative changes to mkfs_hfs(1)
PHCO_31636 s700_800 11.23 Cumulative changes to extendfs_hfs

Resolution:
mkfs has been fixed to print the unallocated sector
information correctly. 64 bit issues in extendfs has been
fixed to allow extension of a HFS file system.

Hi,

I owe a great deal to you !!

After installation of the bundles, I done and get over the smelly stone. :-)

root@xkbqd06# extendfs -F hfs /dev/vg00/rtest
max number of sectors extendible is 49152.
