[Gluster-devel] index_lookup segfault in glusterfsd brick process

[김경표]

Hello folks.

Few days ago I found my EC(4+2) volume was degraded.
I am using 3.12.13-1.el7.x86_64.
One brick was down, below is bricklog
I am suspicious loc->inode bug in index.c (see attached picture)
In GDB, loc->inode is null

> inode_find (loc->inode->table, loc->gfid);
>

Thansk for Gluster Community!!!
