Hi all, Is there any system I could use to content storage space, or atleast have flexable storage space for VMs? At the moment I''m using LVM over AoE, which means if someone needs more space I''d need to grow the LVM partition, then expand the file systems. Any ideas? Thanks -- Ian P.

If so, the only thing that I know of, that has that kind of functionality would be Suns ZFS on Solaris/OpenSolaris. Very cool and has some great features, but not sure if it is anywhere near ready on Linux as of yet. Dan This email is for the intended addressee only.

For 20 domU''s, each wanting 20 gig, that''s 400 gig of storage, in reality most people will use about 2 gig, so we''re look at about 90% wastage in storage space (about the worse case I imagine). I could use CoW with LVM, however that doesn''t really solve the problem of wasted space, as the space still needs partitioning - on top of that the distro used in the domU could be anything, and will not be consistant across domUs. Also, it means people maintaining the domU''s need to use a file system that can grow, and not all support shrinking. Someone can''t just log into a web panel, request a larger/smaller storage space and have it ''just work''. In this situation, I wouldn''t have root access to the DomU''s. The only solution I can think of is running a large NFS mount with quota implemented, that domU owners could symlink into their file system where they need to storage. Thanks, -- Ian P.
