multiple rps
how about of making use of em using a CP like webmin and using each rps as a slave?
Hi
No problem, will propose it though. I do not think NFS can do it, but maybe GFS.
thanks neil! your help is appreciated
I am afraid you cannot join RPS's together even with NFS, but it is an interesting suggestion so I will put it forward.
thanks neil! is there any way to join various rps in one? something like proxmox would do the job?
Hi
Sorry I am not sure what you need to know? I have been reading and see some interesting things going with S3, the only thing I can confirm right now is that we do not offer NFS on new RPS's.
can someone from the staff clear out the nfs type and access please?

I also would prefer unlimited usage for a monthly charge but S3 is only slightly more expensive than additional iSCSI space, so paying for what you use isn't that bad. And its faster than the ~1MB/s on the standard plans
very f.. clever
Thanks

Hmmf. So I guess you could setup an NFS server on one of the RPSes, but whether that's a good idea is debatable.

Yeah, that person was me
Although iSCSI
can be authenticated via CHAP, OVH's implementation doesn't. You can see this when you extract the iSCSI config files from the initial RAM disk. So unfortunately you can't access the same iSCSI target directly from more than one RPS

Correct me if I'm wrong, but I don't think it is possible any more... Multiple RPS can mount the same NFS drive, but iirc NFS is not available any more. iSCSI authenticates by MAC or IP address (I forget which) and does not allow multiple iSCSI 'clients' to mount the same iSCSI disk simultaneously.

Many thanks Myatu! Your knowledge is extremely helpful ! I would love any of the reps (Neil, Marks, Sophie) to be in the forums in a more proactive way
I made the assumption that because people were wget testing it, it was from OVH.

Yeah, and then we realise the file is not OVH hosted, it's in America.

If you /dev/null it, it simply disappears in a big black hole... Even in Full Duplex, you'll notice the difference
Got 10.8MB/s average in Chicago and 10.0MB/s average in Dallas with that .
Edit: Just did it again and got 11.0 and 10.2

Maybe the RPS servers share an internal 1Gbit connection, so at times they will burst above their allotted 100Mbit limit (which OVH does not block as its free bandwith, and it works out better for the client)

RPSs only have a 100mbit port, so the maximum you'll be able to get is ~11.2MB/s. Derchris must have a dedicated server with a gigabit port
Also, remember that write speeds to the iSCSI hard drive are only guaranteed at 1MB/s, unless you get the "Premium" or "Business" plans. So although data can be stored in RAM at 11MB/s, it can't be transferred to the hard drive at this speed.
are those speeds an internal joke (using high end hardware) and pulling my leg or can a rps do 42MB/s????
11 is :O and 42 is please dont sh.. me :P

That makes more sense, and what NFS is good for.
To have a FS available over the network.
Though I don't like the approach of OVH and how they are realising it (ZFS), but that is a totaly different story

Just because he posted it doesn't mean it is a good idea.
NFS is not known for its security precautions.
And mounting the Root partition on another system is, and always will be, a bad idea.

I would say impossible.
Don't know how RPS are working, but it sounds like that the root partition is Mounted via NFS?
If this is the case, then hopefully OVH has setup access restrictions on the NFS shares. Otherwise you would be able to mount any share you want.
The other problem I see is, as you quoted, that it should be possible to mount the SAEM NFS on more then one box.
In general I don't see a problem with that, as thats what NFS is for.
But if my first statement is try about the root partition, then this is a very bad idea.
All node would be writing to the same root partition.
Hi I would like to know how to set up multiple RPS acting as one.
I recall

Another advantage of NFS is that we can use it with 2 or 3 RPS. That means that the same NFS partition is mountable on as many RPS in parallel as you want and they are automatically identical! It is therefore possible to make RPS clusters very easily and almost automatically in 1 click. With the loadbalancing IP, you can create a cluster in a few minutes with 10 RPS.
Now *that* is cool. Can this be achieved without re-installing the RPS?
But I cant figure out how I can do it.
Thanks in advance
