Can I implement a storage similar to GoogleFS with GFS....
No, this is the job for a distributed filesystem like coda, InterMezzo or OpenAFS.
- Maybe I'm missing something but the pool manager seems to be intended to do just that (supports striping and mirroring). --195.99.121.119 14:07, 9 Mar 2006 (UTC)

server and client
An host can be server and client at the same time for the same gfs file system?
- Server and client does not really apply to GFS. You are probably incorrectly thinking it is a network-based file protocol (in the sense of NFS or SMB are). GFS is a disk file system to allow multiple computers to physically mount the same disk over a local disk protocol (such as Fiberchannel, SCSI, Firewire), and allow all computers to safely read/write to the same disk without corrupting each other. -- 216.206.28.116 19:14, 26 Jul 2006 (UTC)

raid- failover of physical storage
I currently have a 1G SAN; right now, I just add disks to the zone for a particular server as needed, and use software raid. works fine. Well, now I need redundant shared block devices, as I'm using xen, and I'd like to enable hot swap (that is, I need a partition that can be seen by two computers at once. It will only be mounted by one at a time, but the cutover from one to the other is very fast) It looks like I can do this with GFS; my question is this: what happens when a hard drive fails? how do I rebuild? what is the impact to the customer?
