I have a bunch of RHEL/OEL Apache VMs (on ESX 3.5) hardware load-balanced into a little http file farm. I need to expand the dataset they're serving from 1TB to 10TB and although I can use OCFS2 and LVM to make it actually work I'm a bit worried about running into any limitations that I'm currently aware of. In particular I'm worried about LUN sizes that LVM is happy to deal with and also the number of files OCFS2 will support in a directory and also per volume. I've looked around in the obvious places but does anyone have any practical experience of this area?
Thanks in advance.
