Q: Given a kernel ATA exception, how to determine which physical disk is affected?

I woke up this morning to a notification email with some rather disturbing system log entries. Dec 2 04:27:01 yeono kernel: [459438.816058] ata2.00: exception Emask 0x0 SAct 0xf SErr 0x0 action 0x6 frozen Dec 2 04:27:01 yeono kernel: [459438.816071] ata2.00: failed command: WRITE FPDMA QUEUED ...

you'd think there'd be a way to find this from /sys, but I can't find the correspondence between ataN channels and the sdX disk(s) on them anywhere

there is a correspondence but it's one level further up, at the level of the SATA controller

2 hours later…

@Gilles Yes there seems to be a wall when forming connections between items within /sys and also /proc too.

Ubuntu 8.04 is old and no longer supported. You should upgrade. If you can't, switch to zsh, which had setopt autocd not only before Ubuntu existed, but I think even before Linux existed. — Gilles 1 min ago

I'm not sure about this one, zsh's changelog only goes back to 2.6beta1 from 1994

it isn't in the changelog from 2.5 either

I've never even seen older versions of zsh, I'm too young for that.

The first public version of zsh (part 1 of 8)
