Quite so often this caused X failing to start because all I/O was busy with caching. Even after letting it to calm down and seeing [btrfs-ino-cache] disappearing from the process list, on next reboot it starts all over again. Here is the fstab entry that I have UUID=430dca92-9541-4201-0f62-373e30beadac / btrfs subvol=root_subvolume,defaults,noatime,noacl,compress=lzo,inode_cache,space_cache,autodefrag 0 0 inode_cache was always enabled since the FS was created about a year or so ago, and actually I have never had any problems with it up until recently. Removing inode_cache option from fstab solves the problem, but I am not sure if it is the right choice. I can observe the problem at least in the vanilla kernel 3.10.4 ~ 6 (did not try older versions) What could be the reason for such behavior and how to avoid it? thanks
