I've got a fresh install of 101a on a thumper with 48 disks and zfs with one large 46 drive raidz2 pool. It has no load at the moment. My problem is that the SUNWhd tools are excrutiatingly slow, by excrutiating I mean that the command : "/opt/SUNWhd/hd/bin/hdadm write_cache display all" takes three hours to iterate over the 48 drives which, I suspect, is not the expected time for such a command to take.
I've hunted around and, while I've seen a few pointers to certain thumpers in a SN range having performance issues, this thumper is not in that range, nor is it running 10u5 or u6. I've come up empty for an explanation so I thought I'd ask here since I know there are some issues with zfs and caching, e.g. the ARC cache, but I'm unclear as to which are currently solved in 101a and which aren't. It could be a simple configuration issue, but I'm unfamiliar with the hardware and would welcome any suggestions or pointers. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
