Hi,
We have a five node cluster that has been running for a long
time (over a year). A few weeks ago we upgraded to 0.87 (giant) and
things continued to work well.
Last week a drive failed on one of the nodes. We replaced the
drive and things were working well again.
After about six days we started getting lots of "slow
requests...blocked for..." messages (100's/hour) and performance has been
terrible. Since then we've made sure to have all of the latest OS patches
and rebooted all five nodes. We are still seeing a lot of slow
requests/blocked messages. Any idea(s) on what's wrong/where to look?
Thanks!
Jeff
