I have a VMware ESXi 4 server and 2 storage servers (mounted via nfs).
Between the storage servers (Fedora 14) is a drbd cluster (dual primary) and ocfs2 filesystem; also every server has a local partition with an ext4 filesystem, both are mounted via nfs on the esxi server.
When I tried to copy a virtual machine (naturally it was powered off) from the ext4 partition to the ocfs2 partition, the vmdk total file size is different, but the md5sum is the same.
On the ext4 partition:
# ls -la total 28492228 -rw------- 1 root root 42949672960 Jan 14 14:46 disk-flat.vmdk # md5sum disk-flat.vmdk 0eaebe3138beb32f54ea5de6dfe5a987
On the ocfs2 partition:
# ls -la total 13974660 -rw------- 1 root root 42949672960 Jan 14 16:16 disk-flat.vmdk # md5sum disk-flat.vmdk 0eaebe3138beb32f54ea5de6dfe5a987
When I power on the virtual machine from the ocfs2 partition it dosn't work. I have a windows on the virtual machine and it freezеs after the windows logo. From the ext4 partition the virtual machine workes.
I tested with linux (created and installed on ext4 partition and then copied to the ocfs2) and the same problem appears.
When I create a virtual machine directly from ocfs2 partition, there are no problems.
I tried to copy via vSphere client, and I have the same problem.
