Good afternoon Btrfs list.
I was working with snapshots and created one of a small filetree as
/btrfs/snaps/0000.101411. Several days late, not having written to the
snapshot, but having written to the original files, I tried to delete
the snapshot. btrfs subvolume delete /snaps/0000.101411 hung the
machine. I had to open a new terminal, ssh in, and use echo b >
/proc/sysrq-trigger (all else had failed) to reboot the machine. Here
are the log entries I recovered. I hope this means something to you
guys because I am at a loss to explain what happened.
