The machine has 16GB Ram and 40GB Swap on a SSD. Its not doing much besides being my personal file archive, so there should be plenty of free memory for btrfs. I have remounted the filesystem with the clear_cache option and now will apply the tweaks mentioned by Duncan. If this does not fix the problem I will install a more current kernel from stretch-backports. Testing currently has btrfs-progs 4.13.3-1. Is this version safe to use and should I upgrade it along with the kernel? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
