[zfs-discuss] df command in ZFS?
I was presenting to a customer at the EBC yesterday, and one of the people at the meeting said using df in ZFS really drives him crazy (no, that's all the detail I have).

[zfs-discuss] Direct I/O ability with zfs?
We are using MySQL, and love the idea of using zfs for this. We are used to using Direct I/O to bypass file system caching (let the DB do this). Does this exist for zfs?

Are there any rules of thumb on how much RAM is needed to handle this (probably RAIDZ for all the disks) with zfs, and how large a server should be used ? If you have a handful of users streaming large movie files over NFS, RAM is not going to be a bottleneck. One of my ultra low-end server (Turion MT-37 2.0 GHz, 512 MB RAM, five 500-GB SATA disk in a raidz1, consumer-grade Nvidia GbE NIC) running an old Nevada b55 install can serve large files at about 650-670 Mb/sec over NFS. CPU is the bottleneck at this level. The same box with a slightly better CPU or a better NIC (with a less CPU-intensive driver that doesn't generate 45k interrupt/sec) would be capable of maxing out the GbE link. -marc ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discu ss Thanks!
