unusual gluster-fuse client load

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



All,

I have an unusual situation.

I have a client whose 1 fuse mount to a volume adds increased load to the machine when its mounted.  When it is not mounted the server is well below 1.00 in top/uptime for load avg.

The strange part is, this gluster volume is mounted across multiple servers in my environment where the load is not observed.  

I've tried strace, and saw nothing usual.  I've even rebooted the client thinking, that there is might be "some odd cache"  but there was no change as the load started to climb after the reboot, and mounting of the fuse filesystem.  

Nothing in the client/server logs regarding that fuse volume.  

Would the community have any suggestions that I might investigate more of?  I haven't tried to wireshark yet.  But i'm not certain I know what to look for if I did capture the tcp dump.

Thanks,
