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@beaglebone:/usr/src/usr.sbin/ypset # zpool iostat 5 capacity operations bandwidth pool alloc free read write read write ---------- ----- ----- ----- ----- ----- ----- bbexport 149M 14.2G 0 4 6.41K 181K bbexport 151M 14.2G 0 16 28.6K 312K bbexport 152M 14.2G 0 6 12.7K 194K bbexport 152M 14.2G 0 6 0 171K bbexport 153M 14.2G 0 6 12.7K 201K bbexport 154M 14.2G 0 8 12.7K 177K bbexport 154M 14.2G 0 6 12.8K 69.8K bbexport 157M 14.2G 0 12 12.5K 547K bbexport 157M 14.2G 0 6 25.5K 152K bbexport 158M 14.2G 0 6 0 162K bbexport 158M 14.2G 0 6 12.7K 136K bbexport 159M 14.2G 0 6 12.8K 164K bbexport 160M 14.2G 3 8 81.7K 174K bbexport 160M 14.2G 0 6 3.09K 166K bbexport 163M 14.2G 0 9 15.5K 459K bbexport 163M 14.2G 0 7 26.9K 164K I am shocked it is working at all considering I could not get a 384M x86 box to run with zfs! -Brett -- wynkoop@wynn.com http://prd4.wynn.com/wynkoop/pgp-keys.txt 917-642-6925 929-272-0000 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. -Honorable J.
