I’ll just toss in here that efixes for this issue are available. As we’re in the tail end of a large data transition and cannot go to LATEST yet, we’re running some efixes for this and they do work. However mmhealth will still report it broken until we can delete the msgqueue. On the positive side, the crashes went away.
I don’t recall the 5.1.2.6 efix #s, but 5.1.3.1. is efix26 for ppcle and 5.1.3.1 efix 27 for x86_64 Ed Wahl Ohio Supercomputer Center From: gpfsug-discuss <[email protected]> On Behalf Of Luke Sudbery Sent: Thursday, October 13, 2022 6:19 AM To: [email protected] Subject: [gpfsug-discuss] Node crashes after upgrading to V5.1.2+ with msgqueue enabled IBM Spectrum Scale : Node crashes after upgrading to V5. 1. 2+ with msgqueue enabled https: //www. ibm. com/support/pages/node/6824149?myns=s033&mynp=OCSTXKQY&mync=E&cm_sp=s033-_-OCSTXKQY-_-E says: IBM Spectrum Scale : Node crashes after upgrading to V5.1.2+ with msgqueue enabled https://www.ibm.com/support/pages/node/6824149?myns=s033&mynp=OCSTXKQY&mync=E&cm_sp=s033-_-OCSTXKQY-_-E<https://urldefense.com/v3/__https:/www.ibm.com/support/pages/node/6824149?myns=s033&mynp=OCSTXKQY&mync=E&cm_sp=s033-_-OCSTXKQY-_-E__;!!KGKeukY!39sbejpLUCp6er4BjDpjPh0bsTcoitFTC1frKvaULMLFEJk3_YlHVGUCYZ5c9mjAq_QLpUVUgnq5KTrM3Q3Ebw$> says: A node crash can occur due to resource exhaustion after upgrading to V5.1.2.0 or higher with msgqueue enabled. This affects all upgraded nodes until the filesystem version is moved to V5.1.2.0+ (mmchfs -V) and the migration off msgqueue occurs (mmmsgqueue config --remove-msgqueue). My emphasis on and. But also says: This issue will affect all versions mentioned above until msgqueue is disabled across the cluster. So it's not entirely clear whether you have to just update client version, update the filesystem version or disable msgqueue or do all 3 to fix it... Can an IBMer clarify?
