Hi
all：
I do the following test：
I create a glusterfs replica volume (replica count
is 2 ) with two server node(server A and server B)，use XFS
as the underlying filesystem， then mount the volume in
client node，
then， I shut down the network of server
A node， in client node， I copy a dir（which has a lot of small files）， the dir size is 2.9GByte，
when copy finish， I
unmount the volume from the client， then I start the
network of server A node， now， glusterfs
self-heal-daemon start heal dir from server B to
server A，
in the end， I find the
self-heal-daemon heal the dir use 40 minutes， It's too slow！ why？
I find out related options with self-heal， as
follow：
Sorry for the delay in response. It is better to enable profile on
the volume and find what is happening. Just before restoring the
network connection, enable profiling using 'gluster volume profile
<volname> start' Let the healing complete. Give the output of
'gluster volume profile <volname> info' output. We can check
that to figure out what is happening.
Pranith
cluster.self-heal-window-size
cluster.self-heal-readdir-size
cluster.background-self-heal-count
then I config :
cluster.self-heal-window-size
is 1024(max value)
cluster.self-heal-readdir-size
is 131072(max value)
and then do the same
test case, find this times heal the dir use 35
minutes, The effective is not obvious,
I
want to ask, If
there are better ways to improve replica volume self
heal lots of small file performance??
thanks！
