I'd like to use it for hosting jails on ZFS, but no matter how I create zpool, I always get a warning about non-native block size: block size: 8192B configured, 1048576B native I know it is optimal for ZFS to have direct access to disks, but HP Smart Array E200 apparently does not support JBOD mode. I tried to configure both single RAID-5 logical volume and four RAID-0 logical volumes, in both cases diskinfo gives me the following: 512 # sectorsize 299966445568 # mediasize in bytes (279G) 585871964 # mediasize in sectors 1048576 # stripesize 643072 # stripeoffset 71798 # Cylinders according to firmware. 255 # Heads according to firmware. 32 # Sectors according to firmware. PA6C90R9SXK07P # Disk ident. With hardware I have, is it better to create single RAID-5 logical volume in HP Smart Array E200 and let ZFS think it deals with single physical drive, or four RAID-0 logical volumes and let ZFS think it deals with four physical drives? Can I just ignore warning about non-native block size? If not, how can I make it go away? Thank you in advance, --=20 Before enlightenment - chop wood, draw water.
