Hello, "darkling" was helping me on IRC for a while before he had to drop off, thanks for the help darkling.
To pick up where we left off... In summary, I have a 10 disk raid6 pool that I cannot mount. btrfs fi show output is here -> http://pastebin.com/aidGV20e 'tank' is the pool in question. mounting fails with errors in dmesg with or without recovery,degraded,ro options. [ 142.588443] BTRFS: device label tank devid 1 transid 14796 /dev/sdc [ 142.589646] BTRFS info (device sdc): enabling auto recovery [ 142.589658] BTRFS info (device sdc): allowing degraded mounts [ 142.589665] BTRFS info (device sdc): disk space caching is enabled [ 142.589669] BTRFS: has skinny extents [ 142.592199] BTRFS: failed to read chunk root on sdc [ 142.612988] BTRFS: open_ctree failed What precipitated all this was horrible performance from the pool, seeing that service times for /dev/sdg were ~ 3 seconds and smartctl reported many sector issues with /dev/sdg. I issued the commant btrfs device delete /dev/sdg and then monitored btrfs fi show but saw no change in allocated data to /dev/sdg for several hours. I then attempted wipefs -a /dev/sdg but it was still listed in the btrfs fi show. I then rebooted, and am at the point where I'm at now. I figured it's best to stop breaking things now and ask for help, if this can be recovered.
