ZFS and UFS have been used (with and without logging). I'm not sure if anyone has tried to use VxFS, but in theory I think it should work as our cache I/O mechanisms are supposed to be FS-agnostic. Note that there is a known (unfixable) issue with ZFS caches that can cause them to take up far more disk space than you have configured. <http://www.openafs.org/pipermail/openafs-devel/2009-September/017033.html> has some information. Decreasing the ZFS recordsize makes it not as bad, though the issue is still always there. You can still have a UFS cache partition easily on an otherwise-ZFS-y system, though. Just make a zvol block device and create a UFS filesystem on that. > When I start afsd with a cache configured on UFS with logging it prints > a warning (see below) but otherwise seems to be working fine.

The original reason for that came from this, I think: <http://www.openafs.org/pipermail/openafs-devel/2002-November/008646.html> and I don't recall anyone doing anything to try to fix or work around it. -- Andrew Deason [email protected] _______________________________________________ OpenAFS-devel mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-devel
