Hi,

I have come across an error when increasing a large filesystem:

# df -k /app/cpsd010/05
Filesystem 1024-blocks Free %Used Iused %Iused Mounted on
/dev/cpsd010_05 268435456 41024068 85% 95 1% /app/cpsd010/05

# chfs -a size=+51200M /app/cpsd010/05
chfs: 0506-932 Can not extend a JFS file system with nbpi = 16384
and frag = 4096 past 536870912 (512 byte blocks).

the filesystem is at its limit due to the nbpi setting.

can someone advise as I am sure that I cannot just increase this setting as it will corrupt the filesystem?

If that is the case does someone have a better procedure than:

1> create another vg / lv / fs on a seperate lun that will allow the fs to be increased to its maximum size.

2> stop the application and copy / migrate the data to the new fs

3> remove the old VG structure and rename the new VG structure.

any help is greatly appreciated.

Thanks

Chris
