#342

Just RAID6 :wink:

15 characters worth of RAID6


#343

Is using a folder action in OSX the easiest way to automate tag removal when adding files to a particular folder?


#344

The I-wanna-fuck-with-linux answer is btrfs. That might be next for me, but I wouldn’t sign someone else up for it. (Raid5/6 with btrfs is broken, don’t use it.)


#345

Haha. Wanna hear some “I-wanna-fuck-with-linux”? I have a machine with coreboot, gentoo, git kernel, and btrfs.


#346

My Synology uses btrfs perfectly, but I don’t have to dick around with it. Just works with out even knowing that it’s using btrfs


#347

Hey! That’s what our server admin uses for our servers! I never wanted to learn about gentoo, but not that I’ve been forced to I kind of like it. and hate it. (git kernel is the only thing in that stack we don’t use)


#348

Not that anyone cares, but best practice these days for throughput with redundancy on spinning disks is a pool of mirrors setup. You add mirrored pairs of drives to a logical pool that the OS can now intelligently spread the IO around to. If a drive fails, you replace it and now only thrash one disk rebuilding instead of the whole array. And because of this, a rebuild is like an order of magnitude faster. Also the end user doesn’t see a huge hit to performance during said rebuild because there’s other mirrored pairs to take the IO load while the one pair is rebuilding.


#349

Just ordered my first 8TB drive. Feels weird.


#350

It’s a magical time to be alive.

I went with 5TB when I build the new workstation, but there was a weird price plateau where they were only incrementally more expensive than a 4TB, but massively cheaper than a 6TB.


#351

Are you doing a cloud backup? If not, I suggest getting another 8TB for some RAID. Just one feels very unsafe.


#352

Ooooo, there’s ZFS on linux now. https://deviant.engineer/2016/02/zfsonlinux-centos7/


#353

ZFS is cool, but it feels like btrfs has destroyed all desire for ZFS.


#354

You are talking about this 8TB hard drive as though it is the only place I’m storing data. Believe me, it’s not.


#355

It’s big enough to be!


#356

Nah. I have 300 GB of data from an 8 day trip to archive, and that is on a restricted amount of filming and photography. The previous external hard drive, at 4TB, filled up in about a year. This should be good for two years.


#357

I’m paying ~$20/mo for my Glacier backups of my NAS currently.


#358

Truthfully I know nothing about btrfs, I’m familiar with zfs from my freenas time. I’ll need to play with this a bit more to figure out how it works and how to get the desired pooled mirror setup.

If you’re setting up a NAS yourself, FreeNAS is still my favorite. Btrfs definitely seems to be the way to go if you want RAID on a linux workstation.


#359

It’ll be interesting to see if btrfs has much of a future, given how Red Hat deprecated it from RHEL over a year ago, given how they (along with CentOS for those who don’t want to pay) are the go to distro for many (most?) enterprise Linux deployments.


#360

That’s interesting that they did that. I was under the impression that btrfs had taken off as the new hotness.


#361

Brief aside. Not sure what the point of paying is really. My last job paid for RHEL and the support was almost exclusively some tech blaming the software we were running rather than actually helping. I’ve been at a CentOS shop for years now and never really missed having paid for it.
