ramdisk from other nodes per nfs

[Bernhard Helmes]

A beautifull day Michael,

I think i can use the ramdisk from other nodes than the master per nfs in order to speed up the cluster.
I have now two systems with 8 Gbyte Ram each and i would use the ramdisk from the second computer for the master.
I have a 1 Gigabit lan and think that the ramdisk from the second computer would be nice to support the master.
I hope that these construction is tricky because i have one ramdisk of 4 Gbyte for the master, a second ramdisk of 6 Gbyte available to the master which should be faster than the hard disk and for the third level i use the hard disk.

Possible or not ?

Nice Greeting from http://www.beablue.de

Hi Bernhard,
I don't see any reason why a ramdisk on an arbitrary node can't be NFS exported to the other nodes. The trick will be to get it properly mounted on all nodes. Doing that will require a little clever scripting, or otherwise just do it by hand. Doing it by hand wouldn't be unreasonable for a small cluster, but it might get tiresome if it needs to be repeated very often.
Cheers, M.
