can you explain it a bit more detailed?
The boxes with disks are now just 'disk servers' and those disks are exported to the servers that will provide the filesystem layer. iscsi is the technology used to export the disks in this scenario.
Is there a neat way to get start the partitions and get them mounted in this setup? I have a server on which I want to create /dev/md0 from two iscsi partitions. I then want to export /md0 to other servers using GFS.
What are you going to use to export the /dev/md0? gnbd? Does your iscsi_target have a maximum of one connection limit?
Do I have to hand-craft my own scripts to start the md devices at boot time and get the filesystems mounted before starting GFS, or is there already a way to do that? (I don't have a problem with doing so, but if there's already a "right" way to do it...)
No idea. I have not actually had a chance to get GFS working whether with iscsi or with some other device exporting solution. Sorry I cannot help here. Maybe those who have had real experience can chip in.
