I had a drive fall off my SCSI external array. It was part of a raid1
mirror, and when it failed off, the md device went into a redirection
loop. Here are some example syslog lines:
Sep 17 15:19:17 db1 kernel: raid1: sdf1: rescheduling sector 129550352
Sep 17 15:19:17 db1 kernel: r sdf1: redirecting sector 129550352 to
another mirror
Sep 17 15:19:17 db1 kernel: raid1: sdf1: rescheduling sector 129550352
Sep 17 15:19:17 db1 kernel: rai sdf1: redirecting sector 129550352 to
another mirror
The drive was sdf1's mirror (sdl1). As far as I can tell, sdf didn't
fail at all. This loop lasted for 5 days before detected, so it wasn't
a simple pause. The thing was stuck in a hard loop, and the filesystem
on the RAID was not accessible. A reboot was required to fix.
Is this a known bug? The kernel being used is Fedora Core 2's
2.6.8-1.521 SMP kernel, which is basically 2.6.8-rc4-bk3.
Thanks in advance for any information,
Philip
