Hi, after switching over to zfs from ufs for my ~/ at home, I am a little bit disturbed by the noise the disks are making. To be more precise, I always have thunderbird and firefox running on my desktop and either or both seem to be writing to my ~/ at short intervals and ZFS flushes these transactions at intervals about 2-5 seconds to the disks. In contrast UFS seems to be doing a little bit more aggressive caching, which reduces disk noise.
I didn't really track down who is the offender and what is the precise reason. I only know that the noise disappears as soon as I close Thunderbird and Firefox. So maybe there is an easy way to solve this problem at the application level. And anyway I want to move my $HOME to more silent disks. But I am curious, if I am the only one who observed this behaviour? Maybe there is even an easy way to reduce this noise. Additionally, I'd guess that moving the heads of the disks all the time, won't make the disks last any longer...
