I am presenting ZFS zvols over iSCSI to other Solaris hosts, but am losing quite a bit of disk space that I don't want to lose:
I create a zvol of 4GB, make a target of it, then add the static-config to the iscsi initiator. When I carve up the disk in format, it sees it as a 128-cylinder disk, and reserves 2 of the cylinders as "spare". That leaves me with a 3.94GB usable space. If I manually change the geometry, I can get the 2 cylinders back (or write a label that has a different cylinder size, reducing the "cost" of the 2 spares), but I don't want to require all of my admins to do these extra steps. It looks like the disk geometry is specified in /etc/iscsi/tgt/<target-alias>/params.0 -- There's entries for heads, cylinders, etc. but I don't see any place to modify these (or to force iscsitgtd to reread them) Is this something that's changeable? --Joe _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
