Thanks for the link, but the main concern in spinning down drives of a ZFS pool is that ZFS by default is not so idle. Every 5 to 30 seconds it closes a transaction group (TXG) which requires a synchronous write of metadata to disk.
I mentioned reading many blogs/forums on the matter, and some did mention hacks from tweaking kernel code to crafting different workarounds which all effect in limiting regular access to a few devices of the pool instead of all devices of the pool. And part of my questions was whether such solutions are public domain and part of common OpenSolaris now? But thanks anyway :) -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
