zfs on BeagleBone

[Brett Wynkoop]

Greeting-

Since someone suggested as part of my testing the USB Flash Disk
crashes on my BeagleBone that I try ZFS I have.  At the moment I am
running the same copy operation that caused it to crash on UFS.

I will report on the success or failure in the original thread.

For now these are my zfs settings for the BeagleBone:

zfs_load="YES"
# from zfstuning wiki
#
vm.kmem_size="256M"

vm.kmem_size_max="256M"

#vfs.zfs.arc_max="40M"
#vfs.zfs.arc_max="64M"
vfs.zfs.arc_max="24M"

vfs.zfs.vdev.cache.size="5M"

and this is what I am seeing writing to the zpool:

root at beaglebone:/usr/src/usr.sbin/ypset # zpool iostat 5
               capacity     operations    bandwidth
pool        alloc   free   read  write   read  write

I am shocked it is working at all considering I could not get a 384M
x86 box to run with zfs!

If cowardly and dishonorable men sometimes shoot unarmed men with army 
pistols or guns, the evil must be prevented by the penitentiary and 
gallows, and not by a general deprivation of a constitutional privilege.
