Re: "Recovering full BTRFS volume"
I used btrfs for years (raid 1) and then ZFS for years (z1 and z2), never had a problem I couldn't recover. These advanced file systems are really essential these days, because drives have just gotten too big to handle with conventional RAID. A 1 in 10e14 error rate means you probably have a least one error come up in your 20TB drive.

I don't know why but my spinny drives last about two years or so of very low usage. I have a large box of crappy drives from this century waiting to be drilled. I have lost only one SSD so far.

Recovering full BTRFS volume — I brought a SSD for my database, and decided to use BTRFS on it since I have read that it is better for SSDs. But after a few weeks my database application crashed because device is seemingly full. SSD has 256 GB of data (now read-only), with ~118 GB of actual files (btrfs fi du agrees). But fi usage says: [preformatted] Overall: Device size: 238.47GiB Device allocated: 238.47GiB Device unallocated: 1.02MiB Device missing: 0.00B Device slack:...
