Hi all, I’ve been working on a Java-esque object-oriented language Bolt that targets LLVM IR. I’m agonisingly close to getting a virtual table working, and was hoping one of you could point out the gap in my understanding. I’ve linked the C++ code snippets relevant to the vtable below. Example IR generated (partially displayed below):

I just built a pair of AWS Red Hat 6.5 instances to create a gluster replicated pair file system.

FWIW, I've got a powershell script that builds an exports.def file for recognizable C functions.

This is also happening when using the C++ APIs. It looks like an MCJIT and SetGC interaction. I'm lost on how to proceed further.

Hi, the $subj warning appears sometimes in syslog, in my case when xfstests/209 runs looped. The minimal reproducer is looped mkfs+mount.

Hi Ravi, thanks for your answer, sure there you go: # gluster volume heal applicatif info Brick ipvr7.xxx:/mnt/gluster-applicatif/brick <gfid:e3b5ef36-a635-4e0e-bd97-d204a1f8e7ed> <gfid:f8030467-b7a3-4744-a945-ff0b532e9401> <gfid:def47b0b-b77e-4f0e-a402-b83c0f2d354b> <gfid:46f76502-b1d5-43af-8c42-3d833e86eb44> <gfid:d27a71d2-6d53-413d-b88c-33edea202cc2>

What does the mount log say when you get the EIO error on snooper? Check if there is a gfid mismatch on snooper directory or the files under it for all 3 bricks. In any case the mount log or the glustershd.log of the 3 nodes for the gfids you listed below should give you some idea on why the files aren't healed. Thanks.

Hello everyone, first time on the ML so excuse me if I'm not following well the rules, I'll improve if I get comments. We got one volume "applicatif" on three nodes (2 and 1 arbiter), each following command was made on node ipvr8.xxx: # gluster volume info applicatif Volume Name: applicatif Type: Replicate Volume ID: ac222863-9210-4354-9636-2c822b332504 Status: Started
