Re: [Moosefs-users] mfsmaster hanging at 100% cpu?

Hi Mike!

 

The situation you describe is quite stange. We would like to connect to your
master with gdb to check this if it were possible. Or maybe your master
constantly swaps? How much RAM do you have? What is the RAM usage? 

 

 

Kind regards

Subject: [Moosefs-users] mfsmaster hanging at 100% cpu?

 

I have a fairly small MFS installation - 14T of storage across 2 servers, a
master node and a metalogger. I'm seeing the mfsmaster jump to 100% cpu and
just sit there... rendering the filesystem dead. strace shows its not doing
any IO.

Any thoughts or ideas where to look next?
