lo all, have a freebsd 7.0-beta4 machine attached to an external disk enclosure and would like feedback on the following setup: have RAID-Z on 4 disks, ZFS volume that takes up entire RAID-Z, use ZVOL from volume for encryption via geli, use .eli (decrypted) device to make another ZFS pool. the idea being "no time/resources wasted doing fscks plus encryption sans hardware RAID". translated to commands this reads: # zpool create p_a raidz /dev/mfid1 /dev/mfid2 /dev/mfid3 /dev/mfid4 # zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT p_a 2.72T 4.02G 2.71T 0% ONLINE - # zfs create -V 2048g p_a/vol # geli init -K /root/p_a.key -s 4096 -l 256 /dev/zvol/p_a/vol # geli attach -k /root/p_a.key /dev/zvol/p_a/vol # zpool create a /dev/zvol/p_a/vol.eli i got a reboot while scp-ing some files to /a (only got ~3 GB in) from another machine with the above setup. am currently waiting far too long for a rm -R <directory> to complete under /a. will test if any of this behavior is repeatable. i welcome opinions or suggestions on the stability of such a setup (ZFS-geli-ZFS) and if this is not stable, as the reboot i just experienced would indicate, suggestions on alternative configurations that allow use of geli and minimize or eliminate fsck time. i do have a preference for no hardware RAID since it ties us to a particular card. will furnish a proper bug report if the reboots are repeatable in the aforementioned scenario. NOTE: please CC me since i am not yet subscribed to this list cheers, jake --
