NAS + HAST + CARP = Redundant Array of NAS?

I know it's been a while since we've looked at NAS, but I found two protocols which seem like they'd be a huge benefit to a NAS setup & I'd love Padre/whomever to cover this in more detail!

1) HAST - High Availability Storage is a way to 

2) CARP - Apparently this isn't a fish?  It seems to be some magic way to allocate a single IP to multiple devices on the same LAN so that we can refer to that single IP while having multiple devices, so that we don't need to change IP in case of failure! -- If only we had a Networking Guru to explain all this...or a community of them ;)

Any idea how easy/painful this would be to implement on a NAS (see below)?  The idea of multiple physical NAS boxes all constantly being constantly synced is awesome, and if it looks like a single box to my machines..even better!  Is there some terrible reason this won't work the way I envision (essentially a network level RAID 1 for your NAS)? Or is this exactly what a NAS should be?



Point of Interest:
I went with NAS4Free over FreeNAS (for reasons--since that's totally an explanation) but the idea is valid for either.

Darn you +Gina Trapani and +Kevin Marks    I've been playing since TWiG >_>

6 hours!

Note: this was taken ~ 3 hours ago (6ish hours after TWiG) because I came up with a better approach and wanted to beat it again >_<

Seems relevant to JuRY, and a good bit (if we hadn't done this already)

Hey Know-It-Alls (or has Padre officially renamed us doge yet? Much Know! So Tech! )

Digressions aside, I'm finding my brain is working entirely too hard trying to track what hardware is in what machine (despite having built them myself).  Besides having functional brains, how do you people keep track of what hardware is in what project?  This would be starting with computers (which components are currently in which machine) and potentially migrate to other things i've already forgotten.

I started doing an excel sheet, but that seems like a terrible idea!  I feel like there's got to be better stuff out there, but a quick search on inventory management software has my eyes spinning.

Any advice is appreciated!

+Timothy Waters I'd be fine going with a database structure, I just feel like i'm recreating the wheel if I start from an empty database!

But I guess i'll go custom spreadsheet/database.  It seems like most existing tools are so overkill they're actually inconvenient or confusing for what i'm trying to do.

Know-How Community, I have a podcatcher dilemma--and hey, you all like to catch some podcasts, right?  Surely you can help ;)

TL-DR:
What's the best way to keep two podcatcher libraries (all machines are on a LAN) in sync so that I don't need to redownload huge video files per each?



Full Version:

We're all podcast fans here, and i'm no exception.  My problem is that I'm a sucker for video (the higher quality the better) instead of audio; yet when you get long high quality video podcasts (like TWiET for a blatant appeal to Padre example) they can be well over a GB, and take an absurd amount of time to download (come on Google Fiber!)

I'd rather not wait to finish downloading a podcast to watch it, especially if it was posted several hours earlier!  The problem is that my desktop is off when i'm not in front of it (eg: asleep or at work) so obviously it can't do the downloading itself.

As it happens, I've got a headless linux box (a 'server') that I keep online & running 24/7 which could easily download the podcasts when they become available.  The problem is that I want to be able to manage my podcasts on the machine I sit in front of, not the one that's always on & doing the downloading.

Ideally i'm trying to keep the downloading tool on my server as light as possible, as it's not exactly a top of the line machine but that's only a preference.  Any suggestions on how I can manage my podcasts on one machine and download them on another, yet not have duplicate copies of the podcasts?

All recommendations & advice are appreciated!  I hope I'm not the only one with this problem...but my Google searching seems to indicate that I very well may be!

Whatever you think about Chelsea Handler, the woman's got giant steel balls. During an appearance on Morgan's lame duck show last night, the comedian told the king of the Twitter tantrum what we all wish we could: that he sucks. It's pretty brilliant.

Make NAS better-er!

What I mean is that we all know we shouldn't rely on a single machine (regardless of how many HDDs it has, and how much parity) to host our files. Yet after building a single NAS (which we've seen on Know How already with FreeNAS), that's easy enough to do.  Maybe we are backing up files to it, maybe we're simply running files from that NAS...either way, having a 2nd (or 3rd, or nth) NAS would be a good idea.


Now you could run a cron job (or even an inotify script) which keeps two or more NAS in sync, but you're still choosing a primary NAS & needing to change all the things (like mount points/file locations & possibly the working of your backup scripts) when that one breaks.

Is there any way to have multiple physical NAS which are identical (or not) but appear to a user to be a single "logical" NAS?  (I'm using disk/raid language with "logical" & "physical" as it's an obvious analogy, but technically a totally different world)  which would appear to the user to be a single machine/drive.  Meaning that if I have 3 NAS, I don't care which NAS the data is coming from, I don't care if a NAS is down, I just want to see the data.

Obviously this is possible, as enterprises have such technology, but what is available to a hobbyist/enthusiast?

If this isn't a feasible approach, what would a good backup be?
