From jlab-scicomp-briefs at jlab.org Thu Dec 4 10:33:39 2025 From: jlab-scicomp-briefs at jlab.org (Wesley Moore via Jlab-scicomp-briefs) Date: Thu, 4 Dec 2025 15:33:39 +0000 Subject: [Moller] [Jlab-scicomp-briefs] Summary of recent filesystem/lustre issues Message-ID: We wanted to provide a brief summary of the recent stability issues some users have experienced. The primary cause has been failing 20TB disks. When these disks begin to die, they can hang in a way that causes ZFS to suspend I/O, which in turn leads to system-wide filesystem stalls and unresponsiveness. In addition, we also identified and replaced a bad memory module (DIMM) in one of the SCOSS systems, which likely caused ? or contributed to ? several of the crashes we observed. These hardware failures together were the major sources of our recent problems. We will continue monitoring closely.
