[LU-11028] RHEL/CentOS 7.5 prevent listing Lustre directory contents

• Type: Bug
• Resolution: Fixed
• Priority: Critical
• Affects Version/s: Lustre 2.10.3
• Severity: 3
• Assignee: Peter Jones
• Reporter: Stanford Research Computing Center

Description

We recently updated our Lustre 2.10.3 clients to CentOS 7.5 (kernel 3.10.0-862.2.3.el7.x86_64) and since then, we have frequent occurrences of directory listing failing:

 

# mount | grep /scratch
10.210.34.201@o2ib1:10.210.34.202@o2ib1:/regal on /scratch type lustre (rw,flock,user_xattr,lazystatfs)

# ls -al /scratch
ls: reading directory /scratch/: Not a directory
total 0

# strace -e getdents ls -al /scratch/
getdents(3, 0x815a10, 32768)            = -1 ENOTDIR (Not a directory)
ls: reading directory /scratch/: Not a directory
total 0
+++ exited with 2 +++

This seem to be the exact same thing that has been reported on https://github.com/zfsonlinux/zfs/issues/7460

 

Could you please advise?

 

Thanks,
