Re: CARP under Hyper-V: weird things happen

Hi Eugene, Might it be the Hyper-V doesn’t properly implement multicast? Or there is perhaps some setting in there to let it work. From memory CARP is not trivial on vmware as well, unless you make special settings. Some ideas here:

I have had disks, that work “perfectly" under UFS and various RAID controllers (and DOS and Windows), but always reported checksum errors when running under ZFS. It would happen on any motherboard or controller. That made me never use anything but ZFS on data that I cannot recreate 100%, fast…

Some further investigation: The HAST nodes do not disconnect when checksum is enabled (either crc32 or sha256). One strange thing is that there is never established TCP connection between both nodes: tcp4 0 0 10.2.101.11.48939 10.2.101.12.8457 FIN_WAIT_2 tcp4 0

HAST instability

I am trying to get a basic HAST setup working on 8-stable (as of today). Hardware is two supermicro blades, each with 2x Xeon E5620 processors, 48GB RAM, integrated LSI2008 controller, two 600GB SAS2 Toshiba drives, two Intel gigabit interfaces and two Intel 10Gbit interfaces. On each of the

ZFS HAST config preference

This is more of an proof of concept question: I am building an redundant cluster of blade servers, and toy with the idea to use HAST and ZFS for the storage. Blades will work in pairs and each pair will provide various services, from SQL databases, to hosting virtual machines (jails and

Re: ZFS - moving from a zraid1 to zraid2 pool with 1.5tb disks

For pure storage, that is a place you send/store files, you don't really need the ZIL. You also need the L2ARC only if you read over and over again the same dataset, which is larger than the available ARC (ZFS cache memory). Both will not be significant for 'backup server' application, because
