  • Did you notice that [livejournal.com profile] bradfitz carefully did not say anything about ads on LiveJournal, nor answer any of the many questions about the possibility? Which is odd considering Mena actually did. (Modulo debates on what constitutes "plastering.")

  • In the meantime, does anyone have a handy tool to archive one's journal and comments? In a more reusable form than screenscraping.

I seek your assistance with Linux bondage. Specifically, the HP Ethernet bonding driver in RHEL 2.1. (What this does is to make two links act like a single link, for increased speed, reliability or both. We're after the reliability.) The bond is set to fail over — to use one link until it fails, then switch to the other and stay there until that fails. But the kernel keeps seeing a link failure when there isn't one and switching to the other link, flapping roughly every few hours. I've kludged around it by setting the downdelay to 2000ms (so it waits two seconds before flapping), but it's still trying to. It's happening on two (identical) boxes in two locations, each with two separate bonded links (one to the NetApps, one to the world), each of whose two links goes to different switches — I'm confident it's not dodgy hardware.

The boxes are DL580 G2, quad 3GHz, 16 gig memory. The kernel is 2.4.9e49-enterprise (that's an old kernel with heavy Red Hat backporting) and it's either that or 2.4.9e57 — nothing later will be a happener. The bonding driver is HP driver 1.0.4q (haven't tried the Red Hat driver). The card driver is Red Hat driver e1000 5.2.52-k1.

Are there any sufferers of Linux bondage who've seen this or heard of it?
