I suspect this is because of the way AFS cache space is handled by afsd. =
When I start afsd with AFS cache on ZFS I get a kernel panic, similar =
to the panic I get if I specify something under /tmp for cache (since =
/tmp is swap which includes RAM; it's not disk cache). Does anyone know =
if support for AFS cache on a ZFS filesystem will eventually be =
implemented, or how I might be able to get it to work? Also, while I =
haven't tried this yet, does anyone know if using ZFS for an AFS server =
partition works? It'd be great if AFS worked with ZFS; performance =
should be greatly improved, plus we don't have HW RAID on our Solaris =
boxes so it would be great for reliability too. Also, we wouldn't have =
to predetermine the partition sizes.
FYI, I'm running Solaris 10 6/06 on our testing server which has a =
single 40GB IDE hard drive, so ZFS is only on a partition of the disk.
