Hi Brandon, Yes, GlusterFS is very cool ;-)

Yes, that is the purpose of AFR.
Now I just have to get ZFS working and YES!
Not sure, if anyone has tried to compile/run glusterfsd on Solaris, but it should be possible. ZFS on linux is too premature....
Kickass! Kudos to the developers. I tried the DRBD/OCFS2 and GFS... and wow, this blows them out the door. I am so stoked in case you couldnt tell, and I havent even done anything with it yet haha.

HOLY OMG CRAP!!! I just setup a 2 machine cluster with glusterfs. omg. I just got done emailing my two bosses with holy F*#k. This is SWEET!! I set up the config so that both machines exported a local /home/export directory, and then both machines connected to both as clients and setup the config to do the AFR so that files were replicated 2 times. WOW... im just sitting in bed on my laptop grinning at the console screen as i create files on each machine and watch it show up on the other and vice versa. Now I just have to get ZFS working and YES! Kickass! Kudos to the developers. I tried the DRBD/OCFS2 and GFS... and wow, this blows them out the door. I am so stoked in case you couldnt tell, and I havent even done anything with it yet haha. I cant wait to mess around with this at the shop on monday and add more nodes. _______________________________________________ Gluster-devel mailing list Gluster-devel@xxxxxxxxxx http://lists.nongnu.org/mailman/listinfo/gluster-devel
