So Ezee is building out in my neighborhood now. I just got conduit installed on my property last week.

I am an IT pro, currently specializing in datacenters, so i'm well versed in fiber communications and such. I would love to be an early adopter.

I can offer a professional assistance during buildout, with tolerance for outages and events that regular customers won't be able to tolerate. I understand when a connection drops because they're dialing in the switches and such.

In exchange, I get hooked up first :)

Is this something Ezee ever considers?

So please have a look at the output here:

Note that /dev/sda is missing one of the stripes. I also have a ton of unallocated space on every drive. How do I fix that?

Note I had a drive crash - /dev/sda crashed and this is the result after a partially successful rebuild. I lost a bunch of data, but now I just want to fix the filesystem so I can move on with my life.

So I have a RAID-5 BTRFS filesystem using 4@6TB drives. I lost a disk, replaced it, and during the reboot, had a power outage longer than my UPS could handle. So my filesystem, when it came back, was extremely corrupted. I was able to recover the files I needed (home movies, etc) but there were a ton of rips of media - around 2500 files - that didn't make it. I knew the risks going in, and the plan has always been if this filesystem barfs I would just re-rip or download the stuff I care about. My question for the group is, are there any options that I have not considered to recover this data?

Scrubs come back with a lot of uncorrectable errors.

Now, while I am not heartbroken thanks to my plan for this data going in, there will be a lot of effort involved in re-ripping all my media. Are there any options available to me to try to recover additional files?
