Hi J.R. thanks for your fast response.

Yes, you're right. > And then, > - mount /aufs_vertex/mnt/aufs/overlay Well, it's kinda difficult to do it that way, cos the creation and mounting of /aufs_vertex is done via /initrc and after the boot It chrootes me into /aufs_vertex . I'll do the mounts etc. from within the aufs_vertex which looks like this: mkdir /mnt/aufs/overlay mount /dev/sdb2 /mnt/aufs/overlay My dmesg sais: EXT4-fs barriers enabled kjournald2 starting: pid 5939, dev sdb2:8, commit interval 5 seconds EXT4 FS on sdb2, internal journal on sdb2:8 EXT4-fs: delayed allocation enabled EXT4-fs: file extents enabled EXT4-fs: mballoc enabled EXT4-fs: mounted filesystem sdb2 with ordered data mode > - write several things to it directly, eg. no aufs Created some files without problems. > - "find /aufs_vertex/mnt/aufs/overlay -ls > /dev/null" repeatedly in > background may be good > - and see what will happen to pdflush. while true; do find /mnt/aufs/overlay/ -ls > /dev/null; done I got about 50% system usage in top but not pdflush or anything. > In /aufs_vertex/mnt/aufs/overlay standalone, pdflush MAY eat your cpu > up. I just want you to make sure. Sorry, I don't understand what that should do. # ln /mnt/aufs/overlay standalone ... hard link not allowed for directory.. # ln -fs ,,, works, but no pdflush load. # cd /mnt/aufs/overlay; ln -fs foo /root works, but no pdflush load. > So your good case is > - linux kernel 2.6.2?? 2.6.28 > - aufs1, last version the stable one from sf > - kde3.5 and kde4 Works both. > and bad case is, > - linux-2.6.29 > - aufs2 > - kde4 > Am I right? Correct. FS for /mnt/aufs/overlay was ext4 for both cases. I try an ext3 overlay now, just to make sure.
