I'm not a dev Petre but just another XFS user. This is the best "solution" I could come up with for your issue. I assumed this "unnecessary" regularly scheduled activity was a house cleaning measure and done intentionally; didn't dawn on me that it may be a bug. Sorry I wasn't able to fully address your issue. If/until there is a permanent fix for this you may want to bump this to 720000 anyway as an interim measure, if you haven't already, as it should yield a significantly better situation than what you have now. You'll at least get something like ~1400 minutes of sleep per day instead of none, decreasing your load/unload cycles from ~2880/day to ~120/day, if my math is correct. -- Stan _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
