Description Joseph Elwin Fernandes 2015-05-06 09:57:00 UTC

Description of problem:

This is a follow up patch for http://review.gluster.org/#/c/10080
In the above, the suggested change in
http://review.gluster.org/#/c/10080/7/xlators/cluster/dht/src/dht-rebalance.c
doesnot work. The reason it doesnt work is promotion and demotion are done in
a multithread way. Whenever a promotion or demotion thread is called, the frame
of the old sync_op thread is not carried with it. As a result the frame->root->pid
is not set.
Solution:
When the file is getting migrated, we get a tiering.migration key_value in the
xattr dict, so that we pass  this dic key-value when we do syncop_setxattr()
to do  data migration and set the frame->root->pid GF_CLIENT_PID_TIER_DEFRAG
in dht_setxattr() just before calling dht_start_rebalance_task().
