This blurb in the latest Kernel Traffic has some status information on
ext3 and ACLs that might be relevant. 12-18mo for a really stable
version, but version 0.02 is supposed (maybe already) to be out very
soon.

GFS is a shared disk filesystem. It doesn't care how the disk is
shared, and one of the side projects
Hmm, well GFS isn't exactly an improvement on NBD, it's more like an

Re: Multi host access SCSI buses.
GFS is what you guys want. Filesystem that will allow multiple access
at the drive level. eg 2+ seperate hosts accessing a drive
simultaneously. Seagate are co-operating to develop a SCSI standard
for drive locking. (firmware updates available).

A few applications for some of this thought.
1) I have long lusted after something Like MC/ServiceGuard on Linux.
My favorite setup is one EMC RAID box being shared by two HP-UX systems,
inter-connected with MC\ServiceGuard. Running thin-server Oracle makes
this a sweet deal. Two of these with Or

I think I saw that on the lkml. There were some problems (mainly performance
under heavy load, IIRC).

Has anyone tried running sw-raid1 over linux's network block device? I've
been tempted, but not quite tempted enough yet.
Does sw-raid1 require synchronous data xfer for the block devices involved?
If so, can sw-raid1 be told to not require synchronous data xfer? Does it
make any sense to do s

Well, rsync isn't real-time data duplication. It's like an intelligent
rcp. What if a database got created and updated and then the host
system crashed 20 seconds before the rsync was scheduled to run? The
data is lost until the original server comes back up. I'd like a
