Hi,

I'm interested in replacing my NFS file systems by CODA (tiny site, just 6 
users), I have started to play with a playground filesystem and am still 
struggling with the authentication mechanism, but my main concern is crash 
recovery.

I am very diligent with my backups, so I don't have an issue with a complete 
lost of hard drive for example (I have successfully recovered from those in 
the past), but right now I use JFS because of the fast recovery from system 
crash. It just replays the log very quickly (faster than ext3). So, how does 
CODA typically handle a machine crash ? Is it completely lost and need to be 
recovered from dump/backup ? Does it need to be fsck'ed ? How fast does it 
take to "repair" it after a crash ?

How often do you typically do the dump ?

Is anybody doing just frequent backup and no dump ?

What's the advantage of the dump ?
My guess is that if you recover from a backup (vs. a dump), then you have to 
recreate your volume on all your servers and clients as if it were a new 
one, right ?


Thanks.
