-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Greeting- I have been banging on my zfs formated usb flash drive for a couple of days with no crashes, and no other problems. I think zfs seems to be working much better than ufs on USB flash drives in the BeagleBone. I previously posted my settings, but here they are again for anyone else who wants to run ZFS on their BeagleBone. /etc/rc.conf: # zfs_enable="YES" /boot/loader.conf: zfs_load="YES" # from zfstuning wiki # vm.kmem_size="256M" vm.kmem_size_max="256M" vfs.zfs.arc_max="24M" vfs.zfs.vdev.cache.size="5M" While the BeagleBone kernel config tells the system to build opensolaris.ko I had to manually locate the zfs module dir and build and install from there. Zfs also seems to have pretty good write speed on usb-flash. My write speeds on copy from the sd card to the usb flash were 5 to 10 times faster. - -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.
