Hi Krishna I have all intentions of mounting the toaster's filesystems on the head node using iSCSI (see my original post), but I have a problem: I have 35 servers in the gluster filesystem that the researchers don't see directly: the head node hides the private network with PAT/PNAT/Masquerading (pick your favorite acronym) so the clients only see the head node but not all the gluster filesystem servers behind it. The glusterfs clients get a wrong image of the gluster filesystem ... I could simply remove the PAT/PNAT/Masquerading (pick your favorite acronym), but I'd rather not do that because that adds an overhead in systems administration and breaks the rule of KISS. -- TIA Paolo Krishna Srinivas wrote: > Paolo, > > You could mount toaster's partition on head node using iscsi. > Run glusterfs server on head node exporting the two partitions. > Run glusterfs client on the researcher's nodes. > > Krishna > > 2008/9/18 Paolo Supino <paolo.supino at gmail.com>: >> Hi >> >> now that I have a new shiney parallel filesystem :-) I want to take >> it a step forward (the fun never ends ;-) ) ... >> A few words on my HPC cluster: >> 1.
