date change on nexentastor rendered it unreachable..

Am now testing NexentaStor on HP ML370 G6 tower, here are the specs, Dual Socket, Quad Core, HT enabled Intel(R) Xeon(R) CPU E5540 @ 2.53GHz 8 Gig ram (4g populated for each proc) L3 cache 8 mb 2 x 73 gb SAS (15k) RAID-1= System OS 6 x 300 gb SAS (10k) RAID-0 single disk in each array to expose the disk for NexentaStor = Storage (RAID 10 = approx 838 gb pool) M410i raid card 256 mb Quad port Multifunction 1GbE card (identified as ntxn0..3 in Solaris (NexentaStor))

NexentaStor 3.0.4 the installation went fine and i even created a volume of 200 gb NFS attached it to the Test Server (XenServer 5.6) copied existing vm from XS local Storage to NFS Storage. configured smtp server for fault alerts.

everything was working fine.

after about 15+ hrs of uptime, i received the following fault alert email notification:

Runner nms-check (description: “Track NMS connectivity failures and internal errors”) went into maintenance state

Before, i could follow the suggestion in the alert i noticed (from the report) that the DATE on the server is old. So i changed the date from console in the recommended format (date -s “20 dec 2010 00:00:00:) then after pressing enter… the prompt took pretty long time to return. and the web console was not responding….

issue: i can ping the host ip locally from the console but not the gateway

1.suspecting the switch port, i connected laptop (windows xp) on the same port and tested it, there does not seems to be any issue with the switch port since i was able to ping the gateway.

2.suspecting the network card: rebooted the server with ubuntu 9.10 x64 live CD configured the network settings, here also there seems to be no issue with the ethernet card

some info: in linux the ethernet driver loaded is netxen_nic drivers, under nexentastor it ifconfig -a shows ntxn0 to ntxn3

the gruelling hrs of all attempt proved futile.. i dont have networking knowledge of solaris platform. linux wether its rpm or debian based distro am quite comfortable…

will update when its fixed…
