Symptoms
Når du har opgraderet en klynge til OneFS 9.1.0.20, viser "isi-status" alle PowerScale-noder i RO-tilstand (Read-Only):
Du vil se poster, der ligner følgende, i /var/log/messages-filen for de berørte noder:

Cause
Problemet synes at være relateret til ændringer af den NVDIMM-statusovervågningskode, der er foretaget i OneFS version 9.1.0.19, hvilket kan medføre, at der opstår en timeout under den oprindelige NVDIMM-statusforespørgsel ved opstart, hvorved noden sættes i skrivebeskyttet tilstand. Selvom efterfølgende statusforespørgsler lykkes, vender noden ikke automatisk tilbage til læse-skrive-tilstand. OneFS 9.2.x og nyere er ikke berørt af dette problem.
Resolution
For at kontrollere, at NVDIMM er sund, og at du er ved at løbe ind i det problem, der er beskrevet i denne KB, skal du køre følgende fire kommandoer:
# isi_hwmon -b NVDIMMHealthMonitoring # isi_hwmon -b NVDIMMPersistence # /opt/dell/DellPTAgent/tools/pta_call get agent/info # /opt/dell/DellPTAgent/tools/pta_call post "host/sensordata?sensorSelector=iDRAC.Embedded.1%23SystemBoardNVDIMMBattery&sensorType=DellSensor"
Disse kommandoer er kun forespørgselskommandoer og bør anses for ikke at afbryde.
Output for kommandoerne for en node i denne tilstand skal svare til:
# isi_hwmon -b NVDIMMHealthMonitoring
DIMM SLOT A7: OK

Det output, der er angivet her, er et eksempel, og der kan være varianser i det output, du får. Den vigtige del er, at outputtet ligner, og at du ikke får en fejlmeddelelse i stedet for outputtet.
- Hvis der er indikationer på kommunikationsproblemer/-fejl, skal du fortsætte fejlfindingen af problemet ved at kontakte en HW L2/SME og/eller PowerEdge-supportteamet efter behov.
- Hvis outputtet indikerer, at NVDIMM er i en god tilstand, og der ikke er nogen problemer, kan du manuelt rydde RO-tilstanden ved hjælp af følgende kommando:
# /usr/bin/isi_hwtools/isi_read_only --unset=system-nvdimm-failed
Når du har anvendt det korrigerende trin, skal du overvåge noden i ~10 minutter for at sikre, at den ikke går tilbage til RO-tilstand. Hvis noden slukkes og tændes eller genstartes, kan problemet opstå igen, og denne løsning skal muligvis anvendes igen. PowerScale Engineering er opmærksomme på problemet og undersøger de løsningstrin, der skal implementeres i en kommende OneFS 9.1-version. I mellemtiden kan du opgradere klyngen til OneFS 9.2 eller nyere for permanent at løse dette problem.
