Hi, I run reiser4 on a laptop. I got serious fsync/flush problem. almost randomly, the hard drive would run busy for minutes to dozens of minutes. while the computer is still responsive during this period, but firefox would hang until the hard gets idle again.
Hm.. firefox is fsync-bound app?
I guess I can set mount options to improve the situation.
That hang can have a complex nature. Well, try to play with the mount option "tmgr.atom_max_size=N", where N is atom size in blocks (by default it is total RAM pages / 4). Look at /proc/mounts to make sure that your changes take effect. If it doesn't help, then let me know. Thanks, Edward.
Any suggestion is appreciated. thanks
