output "bdf" isn't correct

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

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

Re: output "bdf" isn't correct

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.

Re: output "bdf" isn't correct

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

Re: output "bdf" isn't correct

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?

Re: output "bdf" isn't correct

Hi,

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

Re: output "bdf" isn't correct

Hi,

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

Re: output "bdf" isn't correct

The filesystem is free..

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

Re: output "bdf" isn't correct

Hi,

How many space report "du -k" command?

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

Re: output "bdf" isn't correct

the du -sk looks good:

8 /oracle/SID/sapdata5


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