We have 2 virtuals servers (SAPVM01 and SAPVM06) in one physical server.
The first virtual system (SAPVM01) has a total size of 420 Gb and a free space of 170 GB. A SAP system is running.
The second virtual system (SAPVM06) has a total size of 200GB and it is a new system. it is empty.
The goal is to reduce SAPVM01 of 150 Gb and to add this space to SAPVM06.
Is it possible to do this??
Hereafter, some commands that they can help you:
we have VMWARE
the version of LINUX is [FONT=Arial]SUSE Linux ES 10.

Reason: code tags, please...
It appears as though the disk was already allocated to the VM. Also, in this way, I personally believe it was done in an inefficient way.
What is the output of
Code:
df -h
Also, could you add disk to the physical server and then allocate that to the second virtual server?
How much memory exists on the physical machine as well as each virtual machine?
Code:
vmstat -s -S M | egrep 'mem|swap'
You may also want to run top on the physical machine, not to mention, if these are running SAP, depending on the disk subsystem, you may run into contention for I/O and slow both of them down.
Hello guys,
I would like to ask you kindly if you don't know some quick and safe method how to shrink ext4 filesystem and reduce the size of a Logical Volume in Linux, please?

I'm trying to reduce hard drive size (number of cylinders) in SPARC Solaris. Its easy to change last cylinder of last slice, but that cannot be done for slice2/backupslice because it insists on whole disk. If I try to change disk type/geometry, all slices get replaced with some 'default'... (1 Reply)
Hello,
I want to compress any given file or directory. I used
