Greetings, Quick question: I am about to acquire some disks for use with ZFS (currently using zfs-fuse v0.7.0). I''m aware of some 4k alignment issues with Western Digital advanced format disks. As far as I can tell, the Hitachi Deskstar 7K3000 (HDS723030ALA640) uses 512B sectors and so I presume does not suffer from such issues (because it doesn''t lie about the physical layout

Hello, Daniel, Apparently your data is represented by rather small files (thus many small data blocks), so proportion of metadata is relatively high, and your<4k blocks are now using at least 4k disk space. For data with small blocks (a 4k volume on an ashift=12 pool) I saw metadata use up most of my drive - becoming equal to data size. Just for the sake of completeness, I brought up a

Hi, my oi151 based home NAS is approaching a frightening "drive space" level. Right now the data volume is a 4*1TB Raid-Z1, 3 1/2" local disks individually connected to an 8 port LSI 6Gbit controller. So I can either exchange the disks one by one with autoexpand, use 2-4 TB disks and be happy. This was my original approach. However I am totally unclear about the 512b vs 4Kb issue.

I am bumping this thread because I too have the same question ... can I put modern 3TB disks (hitachi deskstars) into an old x4500 ? If not, would the x4540 accept them ? -- This message posted from opensolaris.org

Hi all after being a silent reader for some time and not very successful in getting good performance out of our test set-up, I'm finally getting to the list with questions. Right now, we are operating a web server serving out 4MB files for a distributed computing project. Data is requested from all over the world at a rate of about 650k to 800k downloads a day. Each data file is usually
