crfs cannot create more than one file system on a volumn group

I tried to create multiple file systems on the same volumn group, but
only the first "crfs" command succeeded. The second crfs does not
create a new file system with the proper size, as shown below, any
gocha?

mkvg -fy myfs -S -s 1 hdisk7
crfs -v jfs2 -m /myfile1 -g myfs -a log=INLINE -A yes -t no -p rw -
a size=33000
crfs -v jfs2 -m /myfile2 -g myfs -a log=INLINE -A yes -t no -p rw -
a size=33000

what is the output of lsvg -l myfs volume group.. Also why are you
setting the pp size to 1MB - I would normally let aix figure out the
default pp size for a volume group unless you really need to have
extra small pps for a volume group.

Also do a lspv -l hdisk7 and post your output.

On your second command does it say anything at all? I was able to run
multiple crfs without a issue like your example above only difference
is the vg setup. Also for naming conventions you should try and stick
with volume group names like myvg instead of myfs -- sounds like your
talking about a fliesystem vs a volume group .. ie rootvg datavg etc

Each file-system you create requires a corresponding LV. Since you did
not specify the first one, AIX defaulted to fslv01. You should be
creating a separate LV for each FS, and name them appropriately.

Other issues:
* You have created a scalable VG, with only 1MB PP size. Not sure about
scalable VGs, but for regular VGs there is a limit of 1024PPs per PV,
which means you'd have to provide 1GB Luns! You really should consider
using _at least_ a 128 or 256MB PP size.

* You named the Volume Group myfs???

* You have specified inline logs. Unless you know what you are doing,
stick with the defaults, same applies to using a scalable VG.

* -t no: is the default anyway.

If the command succeeded (return code $?=0), then the fs is there.
What does "df -k" (as opposed to "df -k *") show? What does "lsvg -l
myfs" show?

PS Your command prompt ">" is confusing Google's newsreader - it
thinks that you are quoting original text.

More importantly, I have seen where a ">" prompt truncated files when
someone failed to cut and paste correctly...
(Instead of cut from window one, paste into window two, there was a
cut from window one, and paste back into window one )

But I digress.

AIX will automatically increment the lv names to handle new lv's.
There is no real need to individually name the
lv names. ( It is usually considered a best practice to have names
that will help you remember how the lv is used...but not required)


I think that there is missing information in the original post.
Even if the filesystem did not get created, and there was just a mount
point, df -k * should then showhd4

If you want more help than was already given, Please post the rest of
the df output, and
lspv -l as Mp suggested

Others have given you excellent feedback on the naming of volume
groups, sizes, LV names, and such. And the commands supplied should
help identify what was created on the VG or on the PV.

One thing I would mention though...After creating the FS, did you
mount it? The df command only shows mounted file systems. You can use
"lsfs" command to see ones that are NOT mounted too.

crfs and no mount? And how can a crfs -a size=33000 result in a
filesystem with 200000512 1024-blocks?
