ceph_set_acl() code of 4.4 stable kernel
dentry = d_find_alias(inode);
if (new_mode != old_mode) {
newattrs.ia_mode = new_mode;
newattrs.ia_valid = ATTR_MODE;
ret = ceph_setattr(dentry, &newattrs);
if (ret)
goto out_dput;
}
ret = __ceph_setxattr(dentry, name, value, size, 0);
if (ret) {
if (new_mode != old_mode) {
newattrs.ia_mode = old_mode;
newattrs.ia_valid = ATTR_MODE;
ceph_setattr(dentry, &newattrs);
}
goto out_dput;
}
looks like d_find_alias() return NULL

Yeah, that looks like the problem to me too. If I had to guess then I'd say that setting the ACL raced with an unlink?
It looks like this was fixed upstream in a26feccaba296bd0ae410eabce79cb3443c8a701. Maybe we should consider pulling that in to stable series kernels?
Xiaoxi, are you able to test patches? If so, then could you try applying that commit and see if it helps avoid this?

Do we have a simple reproducer ? I can definitely try it out but I am afraid we cannot build custom kernel and applied to production environments.
It would be great helpful if commit 26feccaba296bd0ae410eabce79cb3443c8a701 can be backported to RHEL 7.3/7.4, thanks a lot.

@Jeff Lee, can the ceph_setxattr introduced by customized location setting ? We set this subdir to a dedicated pool.
Checking with customer regarding their workload though.

I think we hit this again, but these time it hanging there.
