+++ This bug was initially created as a clone of Bug #1774011 +++ This bug was initially created as a copy of Bug #1721355 I am copying this bug because: I'd like to send a patch against it. Description of problem: I was observing this issue while working on BZ 1707259. When there is no self-heals pending, but there are a lot of I/Os happening on a replicate volume with gluster block profile enabled, heal-info was hung. The moment I/O stopped, the command completed successfully. I'm guessing it has something to do with eager locking but I need to RCA it. Version-Release number of selected component (if applicable): rhgs-3.5.0 How reproducible: Always on my dev VMs. Steps to Reproduce: - Create a 1x3 replica volume (3 node setup) - Apply gluster-block profile on the volume. (gluster v set $volname group gluster-block) - Mount a fuse client on another node and run parallel 'dd's : for i in seq{1..20}; do dd if=/dev/urandom of=FILE_$i bs=1024 count=102400& done - After 10-20 seconds while the I/O is going on, run heal-info command - It will be hung. Actual results: heal info command is hung Expected results: It should not be hung.
