several ext3 and mysql kernel crashes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Ext3!

I'm running about 30 dedicated MySQL machines under quite decent loads,
and they are occassionally crashing.  I've been logging console messages
recently in an effort to find the cause, and some appear to be related
to 

I perused your lists and found the message I'm replying to.

If you don't mind, I've included messages and ksymoops from two crashes
that I had recently.  Both were different.  I'm not sure if you have
fixes for them in the new kernel, so I'll be upgrading a few machines
tonight.

I'm running 2.6.10 with the "data=journal" mount option.
Is that the best / safest option for running with MySQL?

In any case, I'm logging all console messages now, so hopefully I can
have more ksymoops output for you soon enough.

I've included the output for each below.

Thank you for your time!
Jason
