I just upgraded to the latest kernel. The /etc/rc.d/mdadm script, which
starts mdadm in monitor mode, reports a segmentation fault in
mdadm --monitor --oneshot --scan.
I also tried to manually start, e.g., mdadm --monitor /dev/md0, and get
a segmentation fault there, too.
Since this did not happen before the kernel upgrade and mdadm interacts
rather closely with the kernel, I suspect that some change in the latest
kernel is to blame for this.
Did anybody else run into the same problem?
Where would I start
debugging it?
Downgrade to 2.6.37.5/6 and confirm it's the kernel.
Then search for a bug, join the bug report, or file one.
I had this on my to-do list already, but I appreciate the suggestion.
Now, the good news is: it's not the kernel, as the same thing happens
with the kernel I was running previously: 2.6.37.5.
The bad news: it still happens, and I think I know the culprit. mdadm
was upgraded along with my kernel upgrade. So occam's razor suggests
the new version of mdadm itself is to blame for the segfault.
Unfortunately, while I diligently keep old versions of my kernel
package, I don't have the previous version of mdadm lying around to
investigate this further. Any suggestions?
And things got even stranger just now, with a silver lining. The
version of mdadm found in [core] is 3.2.1. ABS, on the other hand,
still has the old version (3.1.5). Isn't ABS supposed to be the
official source tree for the official repos? Maybe I misunderstand the
relationship between ABS and the repos.
abs is synchronized once a day
