While performing a resync, iostat shows that nodeA (primary) is doing almost all reads while nodeB (secondary) is doing almost all writes, which is expected. However, I'm trying to see the names of the processes that are doing the reading and writing. I tried enabling /proc/sys/vm/block_dump and checking dmesg, but most of what I see in there is kjournald. Do DRBD processes not show up in kernel debug output? If not, how do I isolate the source of constant 25-50% iowait on a computer running DRBD? -- Eric Robinson Disclaimer - February 16, 2011 This email and any files transmitted with it are confidential and intended solely for drbd-user at lists.linbit.com.
