Hello, I wanted to make sure that my boot slowdown was related to space_cache so I rebooted the PC several times and it did become slower again. What is more, it doesn't seem like I even need to generate any actual IO traffic to trigger this.
I thought I might give clear_cache a shot again and to test the boot speed with nospace_cache as well. After first booting with clear_cache,nospace_cache and nospace_cache afterwards I was unhappy about the boot speed, so I decided to clear the nospace_cache argument so that the cache would be rebuilt. However, even though my boot speed did improve (not well enough, though), I received 2 errors (this is also the output of dmesg | grep BTRFS): [ 5.528707] BTRFS error (device sda2): block group 1103101952 has wrong amount of free space [ 5.529630] BTRFS error (device sda2): failed to load free space cache for block group 1103101952 It comes up after every reboot now. The output of dmesg | grep trfs (no 'b', because it is inconsistent) is: [ 1.225343] Btrfs loaded [ 1.245586] btrfs: disk space caching is enabled [ 1.245588] btrfs: has skinny extents Any ideas on how I can remove this error? This doesn't break my boot or anything, but it probably slows things down, leaves some fs garbage etc. By the way, it would be a good idea to be able to search for a consistent value in dmesg. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
