[Gluster-users] Question to help clarify something with regard to GlusterFS

Hi all,

I've been experimenting with Gluster for about a week now trying to get a
feel for it to see how it might work for us as a back end storage for our
virtual hosts.  While I was reading one day I came across this:

15. I am getting weird errors and inconsistencies from a database I am
running in a Gluster volume

Unless your database does almost nothing, this is expected. Gluster does
not support structured data (like databases) due to issues you will likely
encounter when you have a high number of transactions being persisted, lots
of concurrent connections, etc. Gluster *IS*, however, a perfect place to
store your database backups.

from the troubleshooting page.  This concerns me a little, but I want to
make sure I understand whether this will affect me or not.  Ok, so my file
store wouldn't be storing a database directly, but it would store a VM that
within it would host a database (like MSSQL Server - and actually it would
be a few VMs that would host databases, 2 MSSQL and several MySQL) - would
this experience the same "inconsistencies" as if I had a database directly
stored on gluster, or is it not a problem due to it being VM traffic rather
than a bunch of separate connections to a DB stored in a GlusterFS?

For now I've had to cross off Gluster, but I began to wonder if I
understood the warning in troubleshooting correctly.

Thanks in advance for any info!
