Hi all :) I''ve been wanting to make the switch from XFS over RAID5 to ZFS/RAIDZ2 for some time now, ever since I read about ZFS the first time. Absolutely amazing beast! I''ve built my own little hobby server at home and have a boatload of disks in different sizes that I''ve been using together to build a RAID5 array on Linux using mdadm in two layers; first layer is

I wonder if this is the right place to ask, as the Filesystem in User Space implementation is a separate project. In Solaris ZFS runs in kernel. FUSE implementations are slow, no doubt. Same goes for other FUSE implementations, such as for NTFS. Regards, Tonmaus -- This message posted from opensolaris.org

Hi all I have a test system with snv134 and 8x2TB drives in RAIDz2 and currently no Zil or L2ARC. I noticed the I/O speed to NFS shares on the testpool drops to something hardly usable while scrubbing the pool. How can I address this? Will adding Zil or L2ARC help? Is it possible to tune down scrub''s priority somehow? Best regards roy -- Roy Sigurd Karlsbakk (+47) 97542685 roy at

Could anyone please confirm that the LSI SAS3081E-R works well ? Is hotplug supported ? Anything else I should know before buying one of these cards ? Thanks, Arnaud

Is there a method to view the status of the rams ecc single or double bit errors? I would like to confirm that ecc on my xeon e5520 and ecc ram are performing their role since memtest is ambiguous. I am running memory test on a p6t6 ws, e5520 xeon, 2gb samsung ecc modules and this is what is on the screen: Chipset: Core IMC (ECC : Detect / Correct) However, further down "ECC" is

Which consumer-priced 1.5TB drives do people currently recommend? I had zero read/write/checksum errors so far in 2 years with my trusty old Western Digital WD7500AAKS drives, but now I want to upgrade to a new set of drives that are big, reliable and cheap. As of Jan 2010 it seems the price sweet spot is the 1.5TB drives. As I had a lot of success with Western Digital drives I thought I would
