AlexJ Posted October 6, 2012 Share Posted October 6, 2012 For some reason suddenly my wa usage in top has increased to 20%. The only thing which was done today was to update server to latest debian kernel. Does anyone if this stats are good or bad? I am not sure how to read this stats and what to make out of it.

AlexJ Posted October 7, 2012 Author Share Posted October 7, 2012 Have you just tried booting into the prev kernel? I am not super expert so would need some help. How can I do that? Thanks Link to comment Share on other sites More sharing options...
Grumpy Posted October 8, 2012 Share Posted October 8, 2012 You should be able to select the old kernel as default from your grub. Details, I cannot help with since I don't use debian. Link to comment Share on other sites More sharing options...
p4guru Posted October 8, 2012 Share Posted October 8, 2012 see you're using software raid, which by default so does a mdadm raid check weekly to make sure raid arrays are okay - could be that ? me the raid check usually happens once a week on Sundayscat /proc/mdstats should tell you the status of your raid arrays Link to comment Share on other sites More sharing options...
