PERC H300 megaraid_sas su Debian PROXMOX
martedì, 13 Agosto 2013
Installando un sistema Linux Server, tipo Proxmox (Debian), è possibile monitorare lo stato di funzionamento del controller RAID PERC H700 alias LSI MegaRAID.
Seguendo le indicazioni sul sito hwraid.le-vert.net
E’ possibile aggiungere in /etc/apt/sources.list il repository
deb http://hwraid.le-vert.net/debian wheezy main
ed aggiungere la chiave:
wget -O - http://hwraid.le-vert.net/debian/hwraid.le-vert.net.gpg.key | apt-key add
ad un successivo apt-get update verranno resi disponibili alcuni tools
apt-get install megaclisas-status megacli
è possibile invocare direttamente megaclisas-status
# megaclisas-status -- Controller informations -- -- ID | Model c0 | PERC H700 Integrated -- Arrays informations -- -- ID | Type | Size | Status | InProgress c0u0 | RAID10 | 2454G | Optimal | None -- Disks informations -- ID | Model | Status c0u0p0 | SEAGATE ST900MM0006 LS08S0N08XHB | Online, Spun Up c0u0p1 | SEAGATE ST900MM0006 LS08S0N08896 | Online, Spun Up c0u0p0 | SEAGATE ST900MM0006 LS08S0N08X1K | Online, Spun Up c0u0p1 | SEAGATE ST900MM0006 LS08S0N08875 | Online, Spun Up c0u0p0 | SEAGATE ST900MM0006 LS08S0N07EBR | Online, Spun Up c0u0p1 | SEAGATE ST900MM0006 LS08S0N084P0 | Online, Spun Up
oppure fare affidamento sul demone già attivo dopo l’installazione e far rilevare la presenza in /var/run del file megaclisas-statusd.status

HP Smart Array P410i su Debian Proxmox
lunedì, 01 Luglio 2013
Installando un sistema Linux Server, tipo Proxmox (Debian), è possibile monitorare lo stato di funzionamento del controller RAID hardware HP Smart Array P410i.
In /etc/apt/sources.list.d è possibile creare un file hp.list contenente:
deb http://downloads.linux.hp.com/SDR/repo/mcp/ wheezy/current non-free
curl http://downloads.linux.hp.com/SDR/hpPublicKey1024.pub | apt-key add - curl http://downloads.linux.hp.com/SDR/hpPublicKey2048.pub | apt-key add - curl http://downloads.linux.hp.com/SDR/repo/mcp/GPG-KEY-mcp | apt-key add - [code] ad un successivo apt-get update verranno resi disponibili alcuni tools di HP tipo hpacucli [code] apt-get install hpacucli
è possibile invocare direttamente hpacucli
# hpacucli controller slot=0 ld all show Smart Array P410i in Slot 0 (Embedded) array A logicaldrive 1 (558.7 GB, RAID 1+0, OK) array B logicaldrive 2 (931.5 GB, RAID 1, OK) # hpacucli controller all show config detail Smart Array P420i in Slot 0 (Embedded) Bus Interface: PCI Slot: 0 Serial Number: 5001438023BB5E90 Cache Serial Number: PBKUA0BRH3U0X9 RAID 6 (ADG) Status: Disabled Controller Status: OK Hardware Revision: B Firmware Version: 3.42 Rebuild Priority: Medium Expand Priority: Medium Surface Scan Delay: 3 secs Surface Scan Mode: Idle Queue Depth: Automatic Monitor and Performance Delay: 60 min Elevator Sort: Enabled Degraded Performance Optimization: Disabled Inconsistency Repair Policy: Disabled Wait for Cache Room: Disabled Surface Analysis Inconsistency Notification: Disabled Post Prompt Timeout: 15 secs Cache Board Present: True Cache Status: OK Cache Ratio: 25% Read / 75% Write Drive Write Cache: Enabled Total Cache Size: 512 MB Total Cache Memory Available: 304 MB No-Battery Write Cache: Enabled Cache Backup Power Source: Capacitors Battery/Capacitor Count: 1 Battery/Capacitor Status: OK SATA NCQ Supported: True Spare Activation Mode: Activate on drive failure Controller Temperature (C): 64 Cache Module Temperature (C): 32 Capacitor Temperature (C): 28 ............. .............
per attivare la write cache:
# hpacucli controller slot=0 modify dwc=enable
oppure utilizzare il plugin nagios
# wget 'http://exchange.nagios.org/components/com_mtree/attachment.php?link_id=674&cf_id=24' -O check_hparray # ./check_hparray -s 0 RAID OK - (Smart Array P410i in Slot 0 (Embedded) array A logicaldrive 1 (558.7 GB, RAID 1+0, OK) array B logicaldrive 2 (931.5 GB, RAID 1, OK))

Bond tra interfacce di rete in Proxmox
giovedì, 27 Giugno 2013
Avendo più interfacce di rete disponibili ed utilizzando switch dotati di link aggregation è possibile unire le interfacce in un bond sul quale appoggiare il bridge.
Questo deve essere configurato manualmente in quanto l’interfaccia web di proxmox non prevede questo utilizzo.
/etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet manual
bond-master bond0
mtu 9000
auto eth1
iface eth1 inet manual
bond-master bond0
mtu 9000
auto bond0
iface bond0 inet manual
mtu 9000
bond-mode 802.3ad
bond-miimon 100
bond-slaves none
bond-lacp-rate 4
auto vmbr0
iface vmbr0 inet static
mtu 9000
address 192.168.1.1
netmask 255.255.255.0
network 192.168.1.0
bridge_ports bond0
bridge_stp off
bridge_fd 0
post-up route add -net 10.1.1.0 netmask 255.255.255.0 gw 192.168.2.254
pre-down route del -net 10.1.1.0 netmask 255.255.255.0 gw 192.168.2.254
Il traffico di rete si distribuirà in modo automatico (e non bilanciato) sulle due interfacce aumentando sensibilmente la banda di rete utilizzata.
# ifconfig eth0

IPSET su Debian/PROXMOX
giovedì, 16 Maggio 2013
IPSET su Debian/PROXMOX
L’installazione su Debian/PROXMOX di ipset ha presentato alcune incongruenze dovute a diverse versioni tra tools e moduli del kernel.
Non ho trovato sistema migliore di quello che segue.
apt-get install module-assistant ipset-source apt-get install pve-headers-2.6.32-19-pve cd /usr/src tar vxfj ipset.tar.bz2 cd modules/ m-a a-i ipset
Per non so quale motivo la versione di IPSET nel kernel e quella così compilata differiscono e la versione del tool di gestione fa riferimento ad una versione vecchia,
Per utilizzarla comunque è necessario configurare il depmod per utilizzare il modulo presente nella dir extra appena generato.
Quindi in /etc/depmod.d/ipset.conf si inserisce:
override ip_set * extra override ip_set * extra/ipset
