Hi,
My problem still persist. So I have installed extra Buffalo NAS with ISCSI connections. My configuration is now :
ESX1 server with local store
ESX2 server with local store
Both servers are HA ( cluster )
DELL MD3000 storage system connected via ISCSI
Buffalo NAS connected vi ISCSI.
ESX1 and ESX2 can view both storage systems.
I tested and move few VM to new NAS storage Buffalo. Everything was working perfectly ( shutdow, migrating from one host to other, turn on /off .... ). So I think there is problem in old store on DELL MD3000. Then I test copying VM from old store ( DELL ) to local store of ESX1. The procedure was OK. But when I try to copy VM back to old store ( DELL MD3000 ) error accured :
Error caused by file [esx1-Localstorage] hist/hist_analyzer.vmdk
Task : copy file
For other files the copy procedure was sucesfully, except for vmdk file ( cca. 41 Gb ). And I have enought space on store. So I have to copy file to new store ( buffalo ). This procedure was OK.
I run the same procedure from ESX2 and it was OK. I can copy from old store to local store of ESX2 and via verca.
I have also find the error log ( the store with problems is named VM_store - there are saved VM ) :
At least one corrupt resource metadata region was detected on volume 4d1c7cab-1c64ceea-1298-0010188b4918 (VM_Store). Other regions of the volume might be damaged too.
error
9.8.2013 13:40:15
esx2.xxxx.local
The same error is also for esx1.xxxx.local
From this logs I asume that something is wrong with VM_store ( on DELL MD3000) and the best way is to recreate it ( I think so). But before I do this I have a doubt.
- why everything work on ESX2 when they share the same store ( with ESX1 ) if there is problem with VM_store ? You can copy , migrate, turn on / off VM without any problems.
- why can I copy VM from VM_store to local store of ESX1 but via verca I can not ?
- the true is when I moved VM to new ( Buffalo ) storage everything worked OK.
- could be problem on ISCSI conected from ESX1 to DELL MD3000 ?
