[Gluster-devel] Unify/AFR crashes

[Dmitriy Kotkin]

Guys... 
Is there any chance to fix NS crashes, I/O errors (coz of NS) so far? 
We're in production... so I can't live with it till hash translator...
really. 
If it isn't possible to fix I'll switch to AFR... 

If you have a time to help me and fix this bug please do it. I'm in
#gluster.

Hello Krishna. 

I got the same bug yesterday after you asked me to change transport timeout.

Namespace is activating bailing transport and so on... 

There are some files that I can open (cat) in /storage (i.e. export
directory) but I get I/O errors and NS crashes when I'm trying to open (cat)
it in the mount point. 
These files exist in only one AFR (so there's no bug with existing in 2 AFRs
at the same time for example). 
It's "Open success on child node, failed on namespace". 

I can reproduce the NS crash by trying to do some ops with these "bad
files".

I tried to make a copy of that dir with a fresh content and I got the same
behavior (hang on # cat, bailing) with the same file. 

P.S.: I'm in #gluster.

Dmitriy,
Did you get any help on IRC? What kind of operations do you do
when you say "intense fops"? Does the first node crash? do you
have the core file? if yes can you get the backtrace?
