Hi there, does someone know how to fetch the overall disk throughput? On this particular system I''ve got two locally attached raid controllers serving one vg over two pv''s. iostat shows up a huge list of dm-NN devices, but I don''t know how to identify these devices. I assume these are the lv''s used by the different domU''s. Thanks in advance! cheers, Stephan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Useful for viewing LVM2 statistics. Example: # iostat -N ... utemp_lvm-Home 19.10 13.02 139.80 1965114 21102112 VG - utemp_lvm LV - Home Kupson -- Great software without the knowledge to run it is pretty useless.
