Back on the Kernel list after a long hiatis. Need some experienced optinions.
Current Setup:
Linux Legato Backup server (E1000 nic) Linux-2.4.19-pre4 5xLinux NFS servers (E1000 nic) Linux-2.4.19-pre4
Legato mounts the NFS shares over a Gig ether and uses them as backup media for non-offsite/non-longterm. This works very well when NFS behaves.
The probems is that every now and then the network/nfs just hang up for a while and gets VERY slow. Some research has been done and it seems that the PCI latency is part of the problem, especially when IDE Raid hits the disks hard, this can overrun the buffers on the GigE card.
I've got a test NFS server coming in and will look at upgrading the kernel to 2.4.19-pre11 as there were some bugs associated with E1000 and NFS I saw in pre-[7-9] area. I'm also considering trying to use Network Block Device instead of NFS. Has anyone tried this?
Any suggestions that doesn't involve hitting up a non-existant budget?
Robert
