I was under the impression that meta-data is a filesystem property and is therefore dealt with in the filesystem code, through i/o buffers. Isn't the VM pager responsible for handling object contents (files etc.), only? If so, it would be unfortunate to throw away pages of data but it certainly wouldn't damage the filesystem. As to our own experience: Since I provided the patch a year ago or so we've had tons of users bumping against the space limit of their respective disk containers (with the VM pager involved: Berkeley DB 3, for instance) but not a single instance where the filesystem had been damaged by this incident. This is on the 4.x branch. Uwe -- Uwe Doering | EscapeBox - Managed On-Demand UNIX Servers gemini_at_geminix.org | http://www.escapebox.netReceived on Mon Oct 31 2005 - 14:08:43 UTC
