We have a student working on the problem. But he is still evaluating
alternatives.
I also have applications for r/w replicas. It would be entirely acceptable
for me to mirror writes transparently across two fileservers and be able to
treat that just like a normal r/w volume, with notification of exceptions due
to one of the fileservers failing. I'm going to wind up writing code like
that myself otherwise and playing shuffle magic with volumes -- a transparent
r/w mirror would save a lot of development time...
There are methods outside AFS, e.g. drbd-device, which could be used for
a kind of rw-replication.
And RAID controllers can puke and ruin your whole day no matter how you
architect your array...
Exactly. One is the hapiest man, when one recognizes, that only the
controller died but not the data stored on the disks.
