OCFS2 does not allow sparse disks? I've never heard of that. I have had
tickets open with novell and they have never said it's not supported.
I've emailed this list saying we're using ocfs2 and sparse files and
nobody has raised any flags before (which could be understandable being
a mailing list).
We are currently doing sparse files on ocfs2. It was going fine for
about a year, then we started having problems with ocfs2 becoming
corrupted.
I don't know if the SAN supported thin provisioning, but I'm also not
sure what you mean. Can you elaborate a little?
Thanks,
James
