TechNotes over het gebruik van hoge schijfruimte
Inhoud
Inleiding
Dit document beschrijft een procedure wanneer u een gebruik van een schijf van 100% ervaart en u moet controleren of het een toepassingsprobleem of een hardwareprobleem is, dan moet u meerdere opdrachten uitvoeren om de situatie te analyseren.
Voorwaarden
Vereisten
Er zijn geen specifieke vereisten van toepassing op dit document.
Gebruikte componenten
De informatie in dit document is gebaseerd op de volgende software- en hardware-versies:
- Cisco Unified Computing System (UCS) Series
- Head-end-Packard (HP) servers
De informatie in dit document is gebaseerd op de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk live is, moet u de potentiële impact van elke opdracht begrijpen.
Probleem: Gebruik van hoge schijfruimte
Het systeem werkt langzaam en is niet stabiel. U ervaart een gebruik van 100% van de harde schijf.
Problemen oplossen
De snelle en makkelijke manier is om toegang te krijgen tot de web interface van het beheer en de hardware-status van het opslagapparaat te onderzoeken.
Wanneer er geen toegang is tot Cisco Integrated Management Controller (CIMC) afstandsbeheer voor Unified Computing System (UCS) Series of Integrated Lights-Out (ILO) op HP-servers, u kunt de informatie over de DVD en disk(s) verkrijgen met behulp van deze methode:
Voor Cisco Unified Computing System (UCS)-servers:
Debiaanse distributies gebruiken een pakket met de naam "megacli".
Meer informatie over dit gereedschap - http://hwraid.le-vert.net/wiki/LSIMegaRAIDSAS
Voorbeelden van het gebruik van de opdracht - http://www.mostlychris.com/blog/2009/07/29/check-raid-status-with-megacli/
Het pakket voor het debiër kan worden gedownload en geïnstalleerd.
Om te controleren welke hardwarecontrollers gebruikt worden, voert u de opdracht uit: sudo lspci -vv | grep-i BANK
bijvoorbeeld
82:00.0 VIP-buscontroller: LSI Logic / Symbios Logic MegaRAID SAS 2208 [Thunderbolt] (rev 05)
Kernelstuurprogramma in gebruik: megaraid_sas
meer informatie over deze opdracht is te vinden in :
Runnen als root, commando: sudo/usr/bin/megacli

Stap 1. Zoek uw gegevens van de RAID-controller, voer opdracht uit: lspci-vv | grep-i RAID.
De RAID-controller is een apparaat.
$ lspci -vv | grep -i RAID

Head-end Packard (HP) hardware
Voor HP is er een speciaal pakket voor Debian dat moet worden geïnstalleerd om toegang te krijgen tot de RAID-controller en fysieke disks. Het pakket heet hpacucli_9.40.1-1._amd64.deb
Stap 1. Installatie:
- Meld u aan bij uw Linux-systeem met uw privéaccount.
- Download het pakket voor uw Linux-systeem: wget http://downloads.linux.hpe.com/SDR./repo/mcp/debian/pool/non-free/hpacucli_9.40.1-1._amd64.deb
- opdracht uitvoeren: sudo dpkg -i hpacucli_9.40.1-1._amd64.deb
Als de installatie is voltooid, kunt u met de BAL-manipulatie werken met behulp van het volgende CLI-gereedschap: pacucli
Met het gereedschap kan de juiste informatie worden opgehaald van de RAID-controller en kan de configuratie worden gewijzigd met de inval-onderdelen.
Stap 2. Geef de configuratiegegevens van de controller weer, voer opdracht uit: hpacucli ctrl tonen alle configuratiedetails .

Oplossing
Soms kan een slechte batterij in een van de servers de reden zijn. Je moet het vervangen.
Dit lost het probleem op en vermindert het hoge gebruik van diskprestaties.
