RE: [cobalt-users] NAS as additional/secondary storage?

["Jerry Farquhar" <jerry@xxxxxxxxxxx>]

Okay so if I understand you correctly this time what your inquiring about is
using a hard mounted NFS connection on any supporting piece of hardware (NAS
or type of Server) and using that for additional space requirements for
additional sites.

I suppose it could be done.. I personally have not done that but some one on
the list may have tried it.  We have used NFS mounts for backup purposes to
a NAS server and they work fine but every now and then the connection can
fail.  For backups this is not a major problem.. for active sites this could
be a nightmare.

One thing that comes to mind with that arrangement is a reduced reliability
do to a hard mounted NFS connection over the network at your Co-Lo.  In the
situation your proposing I think your time, effort and $$ would be better
spent simply installing bigger drives in your current server or if it has
the SCSI port on the back of it considering attaching a external SCSI drive
for added space.

Just my personal opinion.

Jerry

read the 2nd post again.... the one you replied to...

<QUOTE>

Perhaps I should have made it clearer - my problem isn't the backup (that's
a doddle across any network) - the thing I'm most interested in is using
space on a secondary box across the network for virtual sites - has anyone
got that working without any serious headaches?

</QUOTE>

I'm guessing by the lack of response that no-one has NFS mounted
file-systems in use for virtual sites - even if it did work, I would expect
issues with multiple RAQs addressing the same space, as each would want to
use site12 say - that would generate "issues"

What I wanted to achieve was an off-machine storage device that multiple
RAQs addressed as their secondary disk - ideally only putting the
/home/sites/site??/logs and //home/sites/site??/web space on the secondary
disk space.

no - I actually said that the backup is the least of my worries - I think
the fact that I mentioned it was a machine with hard disk rather than tape
probably confused my central concern - that is addressing a central chunk of
disk to be used as storage for virtual sites, their logfile and possibly
user space for the virtual sites.

If anyone has ANY external disk, servers etc operating as storage for
virtual sites I'd be interested.
