    Building a (low cost) Linux-based ZFS High-Availability Clustered NAS

    I'm not sure what danswartz is proposing versus the solution I outlined. But if we're talking about the solution described at my Github, there is no impact to a running VM during controller node failover. See:

    Building a (low cost) Linux-based ZFS High-Availability Clustered NAS

    I'm not worried about throughput. The performance profile of a clustered node in my setup is the same as a single node. What I DO have in some setups is a dual active/passive where I pin a zpool to each node. Say I have two zpools housed in different JBOD enclosures. Node1 serves pool1. Node2...

    Building a (low cost) Linux-based ZFS High-Availability Clustered NAS

    No modifications were necessary. It works out of the box.

    Building a (low cost) Linux-based ZFS High-Availability Clustered NAS

    I have quite a bit of experience with this; hence the post sharing my approach. Linux and ZFS isn't a problem, so I'm not sure what you're asserting. Napp-it is a fine product, and I'm certain many are happy with their FreeBSD installations. I'm focused on Linux, though.

    Building a (low cost) Linux-based ZFS High-Availability Clustered NAS

    No, I explicitly do NOT want Solaris-variants or FreeBSD for this application. This is mainly for hardware support and monitoring reasons. I base most systems on HP ProLiant hardware, and make use of the monitoring tools and add-ons available for supported operating systems. These are definitely...

    Building a (low cost) Linux-based ZFS High-Availability Clustered NAS

    Sure. I have setups like this with multiple enclosures as well. Cabling setup is a factor, but performance is really dependent upon pool design and your disk/controller situation. E.g. you can fill a JBOD with SAS SSDs or 10k disks or 7.2 SAS drives... Performance is fine, though. Think of it...

    Building a (low cost) Linux-based ZFS High-Availability Clustered NAS

    I thought I'd share this here since I've used bits and pieces of advice from the forum in the past. I was frustrated with the limitations and cost implications of using commercial ZFS solutions in a high-availability setup. NexentaStor, QuantaStor and Zetavault either had cost or support...

    Anyone tested zetaVault?

    My clients have purchased licensed Zetavault under my direction. Single-node installations have installed and gone fine without incident. This proof-of-concept was initiated by you because you wanted to show us the new HA functionality in Zetavault. We were excited by the prospect. I wouldn't...

    Anyone tested zetaVault?

    Okay, I'll bite... I gave a fair assessment of your product offering in this post. I was not disappointed with Zetavault performance, support or pricing. The breakdown came in communication... They didn't wish to engage over telephone, so my questions about the product played out in long email...

    Anyone tested zetaVault?

    Yeah, Zetavault and DNUK are a wreck from a business perspective. They could fill an open gap in ZFS HA solutions, but alas...

    Anyone tested zetaVault?

    I can add to this... The Zetavault implementation of regular ZFS on a single node is similar to QuantaStor. Ubuntu+ZFS with a basic GUI to manage all aspects of the system. In that mode, it's very affordable. When Zetavault reworked its HA solution, I was intrigued because it differs...

    OpenZFS NAS (BSD, Illumos, Linux, OSX, Solaris, Windows + Storage Spaces) with napp-it web-gui

    Link me! I know they've been through some changes. But it definitely seems time to jump ship.

    OpenZFS NAS (BSD, Illumos, Linux, OSX, Solaris, Windows + Storage Spaces) with napp-it web-gui

    Weird question... Is Nexenta just over? I mean, I've been a longtime user/proponent, but I think I may need to move to another platform for my storage arrays. I'm concerned that the company is unhealthy. I've deployed ~25 Nexenta-based ZFS solutions to clients over the years, and they've been...

    Got a new HP P2000 G3 MSA Array to play with

    Last question. Can you determine if your SSDs linked at 6Gbps? Or are they showing up as 3Gbps?

    All SSD ZFS Pools

    Just curious. Was there every a resolution to this issue?
