To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)



Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

Please show the output of
Code:
lsfs -q /oracle/EP1/sapdata1

I don't know why, but you have different outputs from lslv and lsvg -l commands. According to lsvg -l vg00 your lv_sapdata1 should be 483 PPs, and according to lslv lv_sapdata1 it is 482 PPs.

Then you did show us the output of df but not of lsvg -l vg00 or lslv after issuing chfs. And as zaxxon writes lslfs is very useful too.

When I first starting reading I read over your literal question - the filesystem stats are not changing.

A bit of analysis.

The lsvg output says each PP (physical partition) is 256M (byte) - so 4 of these would be 1 GByte - and 40 would be the 10GByte that du is reporting.

Since 482 are already allocated - chfs simply does the expansion in place - so the lsvg/lslv output should not be changing.

At this point, as pointed out earlier that you have 482 PP in one listing, and 483 PP in another - whoever is running these commands (for you) is not giving you data "as it happens" - short form - I see too many "mistakes" in the data to provide a reply "to the data presented to us".

More analysis and guessing:

Quote:
sapep101dr(root):/home/root>chfs -a size=+512M /oracle/EP1/sapdata1
Filesystem size changed to 253231104
chfs looks at the data in /etc/filesystems (aka LVCB/VG info) and updates that. If another filesystem is mounted over that mount point then df will tell what is mounted over that mount point.

Getting back to the data above - the 2532231104 is in 512 byte blocks. That is roughly 120.75 GByte - and if we multiple 120.75 * 4 (i.e. 4PP per GByte we get 483 PP)

My guess is that chfs is working as it should, but something else is mounted over /oracle/EP1/sapdata1
