Re: Disk unused
;-)
More serious - if you don't know what are you looking for you will probably find nothing!
Hope this helps!
Regards
Torsten.

Re: Disk unused
But what to tell?
Disk are not under volume manager control.
Are the disk mounted?
Are the disk used as raw devices by a database?
Hope this helps!
Regards
Torsten.

Re: Disk unused
> Is there any way to know if the disks "unused" contain data?????
This leads to another question: Do you scrub physical disks when you return them to a free pool? That is, do you erase any LVM metadata if its an LVM disk? [You could use 'dd' or 'pvremove']. If its a raw disk, do you write all zeros or some random pattern with 'dd' to every disk block?
You could write a simple script to write a known "*UNUSED/FREE/AVAILBABLE*" record to a specific disk address to help you in the future.
Once, again, *documentation* is the surest way to know.
I also agree with Torsten --- "unpresent them and wait if someone complains". This is sometimes the "best" way to uncover things long forgotten in complex environments.
Regards!
