<DIV name="wrteplaceholder">I am using drbd 0.6.12 under Linux 2.4.25
and I am using protocol B between the primary and secondary.</DIV>
<DIV name="wrteplaceholder">My machine is a NFS server for a number of
diskless clients.</DIV>
<DIV name="wrteplaceholder">I have encountered a speed problem that
occurs sporadically on the server. The problem occurs while there
is a lot of disk activity (I am running a process</DIV>
<DIV name="wrteplaceholder">that is copying a part of the disk to
another location). Sometimes, the speed of the disk diminishes
considerably during such an operation.</DIV>
<DIV name="wrteplaceholder">For example, the result of the normal
"hdparm -t" command is ~24 MB/s. When the slowdown occurs, the
results are reduced to 1-3 MB/s. Of course, this slowdown impairs
considerably the use of the system.</DIV>
<DIV name="wrteplaceholder"> </DIV>
<DIV name="wrteplaceholder">Does anyone has ay experience with such a
phenomenum (with drbd or without it)? I will appreciate any
insight on the problem and suggestion on how to fix it.</DIV>
<DIV name="wrteplaceholder"> </DIV>
