I'm assuming it will happen again if recovery takes long enough.You're running into a well known, but poorly rectified (if at all) kernel problem, there is little Ceph has to do with it other than doing what is supposed to, move large amounts of data around. Check out: https://bugzilla.redhat.com/show_bug.cgi?id=712019 and linked from there: https://lkml.org/lkml/2013/3/17/50 Ubuntu has this bug logged as well: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/721896 Regards, Christian I was just starting to think this could be a Kernel issue. Thank you for the confirmation. One of the redhat comments says Note if you're not sure which file is cached, you can get kswapd0 out of the loop by doing: echo 1 > /proc/sys/vm/drop_caches I'll give that a try next time. Thanks again. |
