3. I suspected 12.1 new Snapper, cause it by default snapshots your /tmp and /var/tmp, full of small files. I change the snapshot directory option empty, still no luck.
I'm a bit confused Marguerite. In your bug report, comment 4, you said: "even switch the snapper config to my home directory lags too, because there are directories like chromium profiles and mozilla profiles in it. so I just leave the "SUBVOLUME" blank. this time is amazing fast." That makes it sounds like you have a workaround but your point 3 above makes it sound like you don't have a workaround. Which is it?
4. I tried to compile 3.2-rc7 by copying fs/btrfs directory from btrfs core developer's git into it, but the compile will fail at other parts. and I use 3.1.2's desktop and vanilla config extracted from its build service sources, still fails.
I gather from a later forum posting you made that you have now successfully compiled 3.2-rc7 and that it appears to fix the problem when you replace fs/btrfs with fs/btrfs from Btrfs filesystem's core developer Mason's git repository. Which would confirm a btrfs bug. Is that correct? Cheers, Dave -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
