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.
