[Gluster-devel] AFR fails to provide High Availability

Hello everyone,
we are experiencing the following problem in our hpc cluster, with a
gluster filesystem built using unify over afr on several couples of nodes:
Every once in a while, one of our nodes freezes; it will reply to
'ping', but it will not allow ssh connections, nor direct terminal
access. Under those circumstances, the gluster filesystem will crash,
while if the frozen node is shut down, the filesystem will work (in
deprecated mode). Since most of our running jobs use glusterfs to write
in, this is becoming a quite serious problem.
Our server spec files look like:
-------------------------------------------------------------------
### GlusterFS Server Volume Specification
### Export volume brick.
volume brick
type storage/posix
option directory /state/partition1/glfsdir/
end-volume
### Add network serving capability to brick.
volume server
type protocol/server
option transport-type tcp/server
option listen-port 6996
subvolumes brick
option auth.ip.brick.allow 10.*.*.*
end-volume
-------------------------------------------------------------------
and our client spec files look like:
-------------------------------------------------------------------
### GlusterFS Client Volume Specification
### Add client feature and attach to remote subvolume of server
volume brick0-0
type protocol/client
option transport-type tcp/client
option remote-host compute-0-0
option remote-subvolume brick
end-volume
[... several of those, up to compute 7-5 ...]
volume brick7-5
type protocol/client
option transport-type tcp/client
option remote-host compute-7-5
option remote-subvolume brick
end-volume
### Namespace brick
volume local-ns
type protocol/client
option transport-type tcp/client
option remote-host vulcano
option remote-subvolume brick-ns
end-volume
### Automatic File Replication
volume afr1
type cluster/afr
subvolumes brick0-0 brick4-0
end-volume
[... several of those, up to afr24 ...]
volume afr24
type cluster/afr
subvolumes brick3-5 brick7-5
end-volume
### Unify
volume unify
type cluster/unify
subvolumes afr1 afr2 afr3 afr4 afr5 afr6 afr7 afr8 afr9 afr10 afr11
afr12 afr13 afr14 afr15 afr16 afr17 afr18 afr19 afr20 afr21 afr22 afr23
afr24
option namespace local-ns
# ALU scheduler
option scheduler alu # use the ALU scheduler
option alu.limits.min-free-disk 5% # Don't create files on a
volume with less than 5% free diskspace
## When deciding where to place a file, first look at the write-usage,
then at
## read-usage, disk-usage, open files, and finally the disk-speed-usage.
option alu.order
write-usage:read-usage:disk-usage:open-files-usage:disk-speed-usage
option alu.write-usage.entry-threshold 20% # Kick in when the
write-usage discrepancy is 20%
option alu.write-usage.exit-threshold 15% # Don't stop until the
discrepancy has been reduced to 5%
option alu.read-usage.entry-threshold 20% # Kick in when the
read-usage discrepancy is 20%
option alu.read-usage.exit-threshold 4% # Don't stop until the
discrepancy has been reduced to 16% (20% - 4%)
option alu.disk-usage.entry-threshold 10GB # Kick in if the
discrep. in disk-usage between volumes is more than 10GB
option alu.disk-usage.exit-threshold 1GB # Don't stop writing to
the least-used volume until the discrep. is 9GB
option alu.open-files-usage.entry-threshold 1024 # Kick in if the
discrepancy in open files is 1024
option alu.open-files-usage.exit-threshold 32 # Stop when 992
files have been written in the least-used vol.
# option alu.disk-speed-usage.entry-threshold # NEVER SET IT. SPEED
IS CONSTANT!!!
# option alu.disk-speed-usage.exit-threshold # NEVER SET IT. SPEED
IS CONSTANT!!!
option alu.stat-refresh.interval 10sec # Refresh the statistics
used for decision-making every 10 seconds
# option alu.stat-refresh.num-file-create 10 # Refresh the
statistics used for decision-making after creating 10 files
## NUFA scheduler
# option scheduler nufa
# option nufa.local-volume-name afr24
end-volume
-------------------------------------------------------------------
The namespace is provided by the frontend 'vulcano' which does not
otherwise contribute to the filesystem. The scheduler is NUFA for the
nodes and ALU for the frontend. We have lately added 'option
self-heal on' to the afr bricks and 'option transport-timeout 10' to the
basic node bricks, 'brickX-X', but that had no effect on our problem.
What we get in /var/log/glusterfs/glusterfs.log is always something like
this (with two node freeze examples):

It seems to us that gluster still thinks that the frozen node is alive,
at least to some extent, so it does not disregard it as part of the
filesystem. Any ideas on what is happening, and how could we overcome
it? Thanks in advance,
