Recovery from full metadata with all device space consumed?

2018-04-19 Thread Drew Bloechl
I've got a btrfs filesystem that I can't seem to get back to a useful state. The symptom I started with is that rename() operations started dying with ENOSPC, and it looks like the metadata allocation on the filesystem is full: # btrfs fi df /broken Data, RAID0: total=3.63TiB, used=67.00GiB

2006. The generation of Intel based servers that ran pre-Core Xeons are long in the tooth and this is a value judgement but if your data is big enough you need triple parity, you probably shouldn't be running it from an ten year old platform. But that's just me. :-) -- Drew Nothing in life
