Message-ID: <1993Oct4.141045.3924@alw.nih.gov> Sender: postman@alw.nih.gov (AMDS Postmaster) Organization: National Institutes of Health, Bethesda Date: Mon, 4 Oct 1993 14:10:45 GMT Lines: 22 I've installed 386bsd with patchkits 0.2.4. I noticed that after I run shutdown now, the first sync command results in a good half second of disk activity. Subsequent syncs each result in s single click. If I shutdown -r now, I don't think there's an equivalent to that manually issued sync. What's in the disk cache which has to get sunc? Or does it? I have an old SysV machine (3b1) which after a shutdown, goes completely limp. You have to hit reset, so there's never a question whether you should sync or not. You can't. I've also noticed on a Sun IPC, that when you sync after a shutdown, there's disk activity. Any guidance? -- Chuck Bacon - crtb@helix.nih.gov ( alas, not my 3b1 )-: ABHOR SECRECY - DEFEND PRIVACY
