My dear Lantank got up and down more than it should have. Strange. Why? I told it to get up once an hour. Any daemon, yes, devilish one this time, got in? I suspected that the router did some trick. Unhooked the lantank from the network. Nop, he was innocent. What's wrong? I checked into http://supertank.iodata.jp for info. An article in the bbs says that any journaling system does no good. Alright, I emacsed /etc/fstab. There, unfortunatley, were found HDDs mounted as ext3. I had to stop noflushd, immediately. # /etc/init.d/noflushd stop. Then, get it out of the automatic start list. # rm /etc/rc3.d/S80noflushd. OK, a piece of cake. Switch it off. Next day. What? Why is it getting up and down? Stranger than ever before. Well, what run level is it on? Check /etc/inittab. Aha, it gets started with run level 2. So, # rm /etc/rc2.d/S80noflushd. Now, I feel safe and secure like a cat sleeping in a cradle!
