NASLite Network Attached Storage

I'm still having speed problems with Gigabit and NASLite 2.05

After a fresh reboot, it will work for a while and give me about 35MB/sec. easily.

But later it will go back to about 5MB/sec, which is even slower than what I had with 10/100.

I've tried two different systems, a P3 1.13Ghz, and Athlon 1200, both with 512MB of RAM.

Load was over 170% on the Athlon system last time I copied several gigs of files. Even sitting idle, it shows the load between 5 and 17%.

When things are working properly, it doesn't even reach 40% load. Could it be that there is just a messed up driver in NASLite? It's an Intel Pro/1000 card, so I know it is well supported.

Please help me figure this out... I didn't spend $500 on gigabit stuff just to have things go even slower

Can you post a copy of your syslog as it appears after the slow-down occurs?

Hi Tony, Here is the entire syslog. The system has been up for about a month.

Towards the bottom there is some error messages about the hard drives.

Tonight I noticed that the drives connected to the motherboard are slow, while the third drive which is connected to the Sil680 card still gives about 25MB/sec. Hmm...

It started really acting up the other night when I was doing a large backup from my main PC via Rsync. I've tried two different motherboards, so I don't know why the onboard IDE on both are having problems. Maybe it's not the network this time around

Ignore the link messages... I was messing with the CAT5e cable.

Just rebooted the system, and now I get 21MB/sec on the onboard IDE and 40+MB/sec on the Sil680 card.

Also noticed that Disk-2 (the one on the Sil680 card) said the filesystem was not clean, and that there was no journal. Strange since that disk was added after I had upgraded to Naslite-2, which supposedly adds a journal automatically when formatting. I added a journal and rebooted, and now it says the fs is clean.

Maybe I should just connect all the hard drives to the Sil680 card, and leave the onboard IDE for the CDROM only? Kind of a bummer though because I wanted to have room for 6 drives instead of just 4.

Well, it's back to being slow again, down to 2MB/sec on disks 0 and 1, and a system load of over 200%. Disks 2 still gives me over 20MB/sec.

Disk-2 is a Seagate drive and the other 2 are Western Digital. I'm starting to wonder about the WD drives. Though all hard drives are new, and I never had this problem with 10/100 LAN. And all drives are now on the Sil680 card as well.

Here is the newest syslog.

Jul 6 01:40:13 user.warn kernel: ide2: reset: success

The slowdown is caused by the IDE interface dropping DMA support. In the case above (your second syslog) it's disabled due to the IRQ timeout with hde which is a master on one of your IDE channels. Once that occurs both master and slave will be accessed without DMA support for a total throughput of about 2M/s or so.



From the logs it appears that the problem is caused by an IRQ conflict with another active device. The first thing I'll check is the NIC. Generally you must make absolutely sure that the NIC and each drive interface have unique IRQs. Anything short of that will result in compromised performance.

Hope that helps.
