Hello, Iv been playing around with geli, and it seems that the geli -a (aalgo)
option is completely broken.
FreeBSD U1 10.2-BETA2 FreeBSD 10.2-BETA2 #0 d85d061(stable/10): Thu Jul 23

to recreate -# gpart create -s gpt /dev/da0# gpart add -t freebsd-boot -a 4096
-b 4096 -s +1G da0# gpart add -t freebsd-zfs -a 4096 da0 ### note, using -b
4096 returns gpart: autofill: No space left on device, I think this is a bug as
well however off topic.# geli init -e AES-XTS -a HMAC/SHA256 /dev/da0p2 #
note, also tried HMAC/MD5, HMAC/SHA1# geli attach /dev/da0p2# ls
/dev/da*/dev/da0 /dev/da0p1 /dev/da0p2 /dev/da0p2.eli# newfs
/dev/da0p2.eli/dev/da0p2.eli: 14318.0MB (29323256 sectors) block size 32768,

inodes.newfs: can't read old UFS1 superblock: read error from block device:
Invalid argument
The only way to use geli with the -a option, seems to be as swap and it works
perfectly.# cat /etc/fstab/dev/mirror/ssdswap.eli none swap
sw,aalgo=HMAC/SHA256,ealgo=AES-XTS,keylen=256,sectorsize=4096 0
