g_vfs_done

Thu Aug 14 15:25:16 UTC 2008

Hello,

We are using FreeBSD 7.0-RELEASE #1 running Squid and Zabbix on vmware ESX 3.0.2 and our vmware ESX servers access our SAN through IpStor cluster (Storage virtualization and mirroring). 

We have 2 storages (EVA 6100) and the IpStor solution allows us to mirror disks on both EVAs.

We have a problem with both the Zabbix and Squid FreeBSD virtual machines, when the virtual machine is loosing its disks (EVA controller reboot or ipstor cluster failover), we have several "g_vfs_done() : da1s1d[WRITE(offset=2312431234, length=12453)] error= 5" errors then the host is definitively frozen. The disk loss lasts 1-5 seconds. Windows virtual machines do freeze during the loss then continue working. On Windows we had to specify a longer timeout for local disk in registry.

Does anybody has an idea what could be tuned to avoid this problem ?

Attached you can find the dmesg and a screenshot of the g_vfs_done error...

Thanks in advance for your help

Best regards

Carole
