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.
