Why do you want to know? Given the plus and minuses, I am using ashift=12 everywhere anyway, also on real 512b drives. You lose some space ok, it's not an issue unless you know you will fill the disk with files below few tens of kBs.

There's a current use case but for this drive, I can't predict the future.

I gained an answer, I'll vote in due course.

For now –

Code: Select all
macbookpro08-centrim:~ gjp22$ zpool history zhandy
History for 'zhandy':
2012-12-04.21:38:11 zpool create -o ashift=12 -O casesensitivity=insensitive -O compression=on zhandy /dev/disk2
2012-12-04.21:44:10 zfs set snapdir=visible zhandy
2012-12-04.21:44:37 zfs set atime=off zhandy
2012-12-04.21:53:44 zfs set compression=gzip-9 zhandy

macbookpro08-centrim:~ gjp22$


– and as root, a restoration is in progress:

Code: Select all
sh-3.2# zfs send -v tall/backups/zhandy@2012-12-03-090916 | zfs receive -v -F zhandy
sending from @ to tall/backups/zhandy@2012-12-03-090916
receiving full stream of tall/backups/zhandy@2012-12-03-090916 into zhandy@2012-12-03-090916
