Isn't that a bit overhead? And I can't provide /proc/meminfo and
others, as this issue causes a kernel panic a few traces later.
Provide what information you can. Without knowing a single thing
about your hardware, storage config and workload, I can't help you
at all. You're asking me to find a needle in a haystack blindfolded
and with both hands tied behind my back....
I see that xfs_info, meminfo, etc are useful, but /proc/mounts? Maybe
you want "cat /proc/mounts | grep xfs"?. Attached is the output of
/proc/mounts, please let me know if you were really interested in all of
that non-xfs output?
And I just wonder what you are going to do with the information about
the hardware. So it is an Areca hw-raid5 device with 9 disks. But does
this help? It doesn't tell if one of the disks reads/writes with hickups
or provides any performance characteristics at all.
Stuff like /proc/meminfo doesn't have to be provided from exactly
the time of the crash - it's just the simplest way to find out how
much RAM you have in the machine, so a dump from whenever the
machine is up and running the workload is fine. Other information we
ask for (e.g. capturing the output of `vmstat 5` as suggested in the
FAQ) gives us the runtime variation of memory usage and easy to
capture right up to the failure point...
I have started collectl now, it logs meminfo and other useful
information. But still with all of that, are you sure xfs debugging
information wouldn't be more useful? For example setting a
"#define debug" in xfs_trans_ail.c?
Cheers,
Bernd
