What happens if you do a "mount -o remount" on an NFS root? Is it just ignored? It is possible to set some options on the command line. See linux-2.4.26/Documentation/nfsroot.txt > Right now the only reason I'm even using NFS is because a Xenoserver > provider needs to be able to do backups, migration, failover, and so on. > How are other people meeting these requirements? Has the CoW > development stalled? NFS root should be a good strategy -- its unfortunate the Linux code has problems. If you can find a reliable way of triggering the Linux lockup, we'll have a sporting chance of being able to fix it, and hopefully get a patch into the mainline tree. Bin Ren developed a CoW block device driver, but I don't think its received a huge amount of testing. Bin: could you check this in? We also have a user-space CoW NFS server that runs in domain0 and exports file systems to other domains. This is undergoing testing right now. > What about live migration? Live migration is now working nicely -- I've got "one last bug" that effects SMP systems then I'll check it in. Ian
