If we were using a system like AFS ... AdvFS is also good at this. Without a SAN backend, it's really nice to be able to migrate data from a 4GB disk to a 36GB disk without any outage. It would be _really_ nice if someone managed to implement the equivalent of addvol and rmvol in UFS. On Thu, 2005-Sep-15 09:42:28 +0930, Greg 'groggy' Lehey wrote: >partition.

It's still useful to be able to segregate highly volatile data from relatively stable data. Mostly read-only root filesystem is far more likely to survive a serious melt-down. -- Peter Jeremy
