output "bdf" isn't correct

centurion — Wed, 26 Jan 2011 06:53:06 GMT

/dev/vgsap/lvsapdata5
524156928 51168 520025208 0% /oracle/SID/sapdata5

There is nothing stored in the filesystem. But there is a lack about 4GB ?!

HPUX 11.31

Hi,

Hints:
Before mounting the file system ensures that mounting point directory are empty.
If you have used some .dbf file inside of this mounting point you must shutdown your Oracle instance to release used space.

Looks like a very big file system 524 Gigs
and there are some meta data space reservations
for every vxfs file systems say around 1% or slightly less than that.

However in your case it`s < 1 % ,4 Gigs.

This is pretty much expected behavior.

Thanks

oracle is not running at the moment. there are only a few folders without content.

at the production system I have the same size of filesystem, but there it's ok:

/dev/sap/lvsapdata1
524156928 523573856 578568 100% /oracle/SID/sapdata1

I remount all filesystems, but no way.

Any ideas?

Hi,

Please check if your file system is really free or is busy by any process:
#fuser -u /dev/vgsap/lvsapdata5

Rgds.

Hi,

Have you checked the current file system consistency by "fsck" command?

Rgds.

Re: output "bdf" isn't correct

centurion — Wed, 26 Jan 2011 08:45:49 GMT

The filesystem is free..

root@de06s209 [/oracle/TF3]# fuser -u /dev/vgtf3/lvsapdata5
/dev/vgtf3/lvsapdata5:

fsck is working without errors

Hi,

How many space report "du -k" command?

Also please remember that your disk manager subsystem reserves several space for internal uses, metadata, etc.

Rgds.

Re: output "bdf" isn't correct

centurion — Wed, 26 Jan 2011 09:05:52 GMT

the du -sk looks good:

8 /oracle/SID/sapdata5

About reservation/metadatas, see my entry above about our production system. There it's ok.

Hi Centurion,

I agree with the previous assessment of Manix, please consider spending of 1% or less for internal management of your disk manager.

Rgds.

Re: output "bdf" isn't correct

centurion — Wed, 26 Jan 2011 09:17:53 GMT

Jose, I'am with you. But are you shure?

Because on our other system, the same configuration, we haven't these less for internal management ?!

Re: output "bdf" isn't correct

Jose Mosquera — Wed, 26 Jan 2011 09:24:06 GMT

Hi again,

Have you the same patch level in both systems?

Re: output "bdf" isn't correct

centurion — Wed, 26 Jan 2011 09:26:56 GMT

the sole difference is, that the affected system is a vpar..

Re: output "bdf" isn't correct

Jose Mosquera — Wed, 26 Jan 2011 09:34:11 GMT

What show you this output command in both systems:
#fstyp -v /dev/vgsap/lvsapdata5

Are you using a Disk Array, is the same for both? Or are using separate disk devices?
Same RAID Layout for both?
Are there the same mount options for both boxes on /etc/fstab files?

Have you created both Volume Groups with the same physical_extent_size, please attach the outputs of:
#vgdisplay -v vgsap

Re: output "bdf" isn't correct

centurion — Wed, 26 Jan 2011 11:42:23 GMT

everything is the same (storage-box, raid, pe, pe-size,..).

I made now a newfs and I have the same value as before. I think there is a difference to the hpux vpar-vesion. :-(

I'm 100% sure it is not related to vPars...
