Hello Shehjar

I moved away from GlusterFS. At least for this particular setup. I would have loved to use GlusterFS but it does not work stable enough for me. I had this system prepared for some time and wanted slowly to move users from my old mail server to that new system. On Sunday I had to move users because the old server had a hardware issue. Whole Monday was a mess. GlusterFS was crashing with a such high rate that on Monday after office hours I decided to move everything to NFS. Since then I have no real issue (and I do not have the replication stuff I loved to have).

I can't produce you that backtrace from GDB. I moved everything away from GlusterFS. I still have the old configuration on the two systems and could try to reproduce the error but maybe I can't. My old tests with just my sitting on the GlusterFS server never where so catastrophic as when I moved around 300 mail domains to run on top of GlusterFS.

During Monday this week I did remove io-threads and NUFA and things where more stable but still not enough stable. At the end I just had posix locks and AFR. Nothing more and nothing less. But that still did not help to make GlusterFS stable enough for me.
