[Gluster-users] Segfaults after upgrade to GlusterFS 3.10.9

[Frank Wall]

Hi,

after upgrading to 3.10.9 I'm seing ganesha.nfsd segfaulting all the time:

[12407.918249] ganesha.nfsd[38104]: segfault at 0 ip 00007f872425fb00 sp 00007f867cefe5d0 error 4 in libglusterfs.so.0.0.1[7f8724223000+f1000]

ganesha-fgapi.log shows the following errors:

[2018-01-18 17:24:00.146094] W [inode.c:1341:inode_parent] (-->/lib64/libgfapi.so.0(glfs_resolve_at+0x278) [0x7f7cb927f0b8] -->/lib64/libglusterfs.so.0(glusterfs_normalize_dentry+0x8e) [0x7f7cb8fa8aee] -->/lib64/libglusterfs.so.0(inode_parent+0xda) [0x7f7cb8fa670a] ) 0-gfapi: inode not found

This leads to serious availability issues.

Is this a known issue? Any workaround available?

FWIW, my GlusterFS volume looks like this:
