[TargetCLI ZFS / ESXi] Onverklaarbare crashes

[FireDrunk]

Allereerst mijn setup:

iSCSI host:
Xeon E5-2560v3
64GB RAM
4 NIC's met 4 ip's in 4 verschillende subnets
LUN 0: 2 * 128GB SSD's in een ZFS Mirror
LUN 1: 4 * 256GB SSD's in 2 ZFS Mirrors (RAID10 like dus)

iSCSI Client:

ESXi 6.0u1 host
Intel i5-3570
32GB RAM
4 NIC's

Mijn iSCSI Configuratie:

[root@NAS thijs]# targetcli

VH01 t/m VH04 zijn momenteel niet in gebruik

De ESXi host is voorzien van multipathing naar de 4 verschillende ip's van de iSCSI host.
Alles werkt perfect, en ik satureer bij benchmarks de 4 links, so far so good.

Na verloop van tijd (vooral als ik meerdere dingen tegelijk doe) crasht de hele ESXi host omdat de iSCSI verbinding wegvalt.

Laatste stuk van de logging:

Ik zou niet weten waar het in zou kunnen zitten, kan iemand mij op weg helpen, met waar ik het in moet zoeken?

EDIT:
Als ik de sense data (0x05, 0x20, 0x00) op zoek (http://www.t10.org/lists/asc-num.txt) krijg ik dit resultaat:

20h/00h  DZTPROMAEBKVF  INVALID COMMAND OPERATION CODE

Iemand die dit kan bevestigen? Debug ik dit op de goede manier? Want dit zegt mij vrij weinig dan dat ESXi iets probeert wat TargetCLI niet ondersteund.

[Oid]

misschien lees ik er over heen; maar welke OS draait de iSCSI host?
Als je een tweede host koppelt disconnect die dan ook?

[FireDrunk]

Host is Fedora 23, tweede guest kan ik ook eens doen, dat is een goed idee.

[CAPSLOCK2000]

Misschien ten overvloede, maar als je het nog niet gedaan hebt, lees dan de VMWare documentatie, dat geeft een beetje inzicht in wat die logs betekenen.

https://kb.vmware.com/sel...playKC&externalId=1029039
https://kb.vmware.com/sel...splayKC&externalId=289902

In mijn ervaring zijn iSCSI-problemen meestal problemen met het onderliggende netwerk. iSCSI stelt hogere eisen dan de meeste andere protocollen en heeft het eerste last als er iets mis gaat. Ik zou dus goed opletten of ik tekenen zie van netwerkproblemen. Bij verzadigde links kunnen kleine verstoringen al grote gevolgen hebben.

[FireDrunk]

Ondertussen eens getest met de vier andere hosts (die een tijd uit stonden, wegens lage utilization )
Nu dus 4 hosts er bij, welke allemaal met dual gigabit en dezelfde multipathing configuratie aangesloten zitten.

4 VM"s tegelijk het commando:

dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync

uit laten voeren, en alles werkt keurig. De iSCSI host verstookt rustig 35k sync IOPS bij de eerste run, en bij de tweede run al een stuk minder (dedup & compressie staan aan).

Ik begin te vermoeden dat het aan die ene 5e host ligt, maar wat vreemd is, is dat nadat alles gecrasht is, en ik de VH05 herstart, niet alles goed opkomt, tot ik de iSCSI host een trap verkoop. Alsof er iets in de Target kernel module mis zit. (maar 1 van de 2 lun's is te mounten).

Na een herstart van zowel de ESXi host als de NAS werkt alles weer naar behoren.

Ga nu eens benchen met alles hosts tegelijk. Geen verschil, alles blijft gewoon werken.
Ik heb 1 miscompare gezien:

0x85 is te negeren, dat is het ATA PASSTHROUGH commando wat ESXi probeert te doen, maar dat is geen blocking issue.

[CAPSLOCK2000]

Doe je iSCSI helemaal in software (daar lijkt het op) of heb je nog iets van hardware-acceleratie?
Draait alles op dezelfde firmware-versie?

[FireDrunk]

Alles draait op software (Software iSCSI Adapter in ESXi, en Linux Target Kernel module).

_{Niet dat ik denk dat dat uitmaakt, alle grote SAN/NASsen draaien ook gewoon software}

[CAPSLOCK2000]

Ik probeerde niet te zeggen dat hardware beter is, doe mij ook maar software, al is het maar omdat je dan geen firmwareversies hoeft bij te houden

[FireDrunk]

Dat is zeker waar

[FireDrunk]

Zojuist na lange tijd weer eens een flinke crash. Ik was een nieuwe VM aan het uitrollen dmv salt-cloud.
Het ging dus om het klonen van een template denk ik.

*subtiel schopje*

Even met wat kennissen overlegd, en misschien wordt het tijd om een test te doen met FreeNAS op dezelfde (SSD) pool. Op zich sluit je dan het hele netwerk en ZFS gedeelte uit, en test je vooral een ander iSCSI stack.

Ben je hier nog verder mee gekomen?

Ik heb een Synology iSCSI target, 10Gbe >> 10Gbe switch >> Windows 2012R2 server met 10Gbe NIC en heb op de meest vreemde momenten last van het wegvallen van de iSCSI schijf binnen Windows.
Je kunt bijvoorbeeld een uur lang met 1GB/s benchmarken zonder problemen, en 's-nachts zonder load knalt hij er ineens een minuut uit.


Windows 2012 R2 server,
system log:

code:

12:41:17: Initiator sent a task management command to reset the target. The target name is given in the dump data.
12:41:37: Target failed to respond in time to a Task Management request.
12:41:37: Target did not respond in time for a SCSI request. The CDB is given in the dump data.
12:41:37: Can not Reset the Target or LUN. Will attempt session recovery.
12:41:40: Target returned an invalid login response packet. The login response packet is given in the dump data.
12:42:09: A connection to the target was lost, but Initiator successfully reconnected to the target. Dump data contains the target name.

Op een andere locatie heb ik zo'n zelfde setup draaien zonder problemen. Het enige verschil is dat er daar geen 10Gbe switch tussen zit en de Windows server rechtstreeks zit aangesloten op het Synology iSCSI target.
Binnenkort die switch maar eens een reboot geven...

Ik heb geen definitieve oorzaak gevonden, maar ik werd recentelijk getriggerd dat er een bug zit in de Intel 1000/PT driver code onder ESXi 6.0U2. Bij hoge load kan de netwerkkaart driver crashen.

Dat verklaart waarom ik geen specifieke foutmeldingen kreeg op de iSCSI host.
