Mittwoch, November 7th, 2012VMware Knowledge Base – Broadcom 5719/5720 NICs using tg3 driver becomes unresponsive and stops traffic
Mittwoch, November 7th, 2012
When a system uses the tg3 driver with 1 Gb NICs the logs report excessive NetQueue messages similar to:
… cpu14:2091)<6>tg3 : vmnic3: RX NetQ allocated on 1
… cpu14:2091)<6>tg3 : vmnic3: NetQ set RX Filter: 1 [00:50:56:7f:96:94 0]
… cpu12:2091)<6>tg3 : vmnic3: NetQ remove RX filter: 1
… cpu12:2091)<6>tg3 : vmnic3: Free NetQ RX Queue: 1
This issue is seen to occur on Broadcom 5719/5720 NICs where the NICs stop functioning or responding when used for NFS or virtual machine network traffic
To work around this issue turn off NetQueue
# esxcli system settings kernel set -s netNetqueueEnabled -v FALSE
# reboot

FreeNAS 8.3.0 Beta 1 – ZFS v28 includes deduplication
Donnerstag, November 1st, 2012
In FreeNAS 8.3 deduplication can be enabled at the dataset level and there is no way to undedup data once it is deduplicated. The more data you write to a deduplicated dataset the more RAM it requires – importing an unclean pool can require between 3-5 GB of RAM per TB of deduped data and if the system doesn’t have the needed RAM it will panic. Think carefully before enabling dedup!
