Depending on how easy it is to make it click, a binary search pattern may work OKish to find out which disc it is, still requires a bit of manual cable plugging, but at least only a few trys.

I think i can figure out which disk is clicking, as they are hot swab bay. i can remove each disk one at a time to figure out if the clicking stops, and which disk is making the sound.
There are actually two symptoms... The server takes atleast 30 mins to start, the windows startup screen keeps processing for a very long time this screen...



The other symptom is the clicking sound, its an ongoing sound, i can hear it for hours.. even if i dont access it.

If the drives are easily accessible you should be able to feel the clicking if you put your finger on each drive.

Is your boot drive one of the HDDs?
post #1204 of 3346
SMART tests came out clean for each hard disk with analyze, short test and test logs option in FlexRaid.

The clicking stopped, But the disks are extremely slow. Each time i try to access any of the disks it takes like 15 mins. Worse each time i try to boot, the windows boot screen keeps processing for atleast 30 mins or more.
This screen...



Is it possible that there could be some structural/logical problem rather than physical.?
Strangely none of the drives are clicking now. Server's been up all day, but no clicks.

Did you test your OS drive as well?

havent tested that yet. I am downloading a free third party software to do that.

Although i have crystal disk info installed, which does not show any issue, but i think i need something that can scan for the disks for S.M.A.R.T tests for the OS drive.
Working on that now.

As I mentioned to you via PM a clean SMART report doesn't rule any of them out. It just didn't rule anything obvious in.

If you mentioned it I missed it but how long had you had this up and running before you started having issues?

Been up since almost 4 months now.

Oh yea, i had two spare hard disks sitting 1TB and 2TB.. i just added to two empty bays, but never put them in the flexraid config. I almost forgot about it.. It was never in use. Just pulled it out.. and restarted the system. Windows reported there has been a change in the hardware do you want to run a repair, i skipped and now its back to the ssame old windows booting session been booting for 20 mins now.. might start in another 10 mins.

I would start by doing whatever you can to erase any trace of those 2 drives ever having been in the system.
post #1212 of 3346
Issue identified!!!
Was up last night, tried almost everything to figure out whats happening. Luckily, out of curiosity i was curising through the various options under FlexRaid, and under Drive Manager i see that all the disks look healthy, EXCEPT for Parity disk which was showing MISSING status.



I am not sure if its unable to read the disk due to some reason, or the drive drops out the config db, but SMART tests runs just fine.

FInally after removing the parity disk the system boots up normally, no delays, no slowness. So it does look like irrespective of the SMART results there is an issue with the Parity disk.
Now how can i rebuild the parity disk to a new disk? I have few disks of the same size of the parity (3Tb) in the flexraid pool in DRU UoR Type sitting unused. Can i pluck out one of the disk from there and re-create parity?

Or is it an issue with a curropt configuration?
post #1213 of 3346
If you need to re-create the parity anyway, its probably a better idea to delete the config in FlexRaid and create it again with the updated drive assignments, that way you can be sure nothing is left over from the old config.
post #1214 of 3346
You might want to consider using a new 4tb drive for your parity drive. This will give you an upgrade path in the future.
post #1215 of 3346

I would replace the drive, or select another for parity duty.

Delete your flexraid config.

Create a new config, assign the new parity. Initialize.

You should be all set in about 10 hours biggrin.gif

Good idea if your thinking you want to add 4 TB drives in future.

I'm skipping them. There isn't any good 7200rpm drives available, and there isn't any price difference per TB over the 3 TB. I just keep using those because I'm too lazy to upgrade my parity drive biggrin.gif

It's on my to do list but just never urgent.
Have you done it ?

I think I might skip right to 5 TB.

You don't have to create a new config to upgrade the parity drive.

Maximum PC tested the new 5900rpm Seagate Barracuda 4TB and they were just as fast as the 7200rpm 3TB models because they use 1TB platters instead of 750MB platters.

That is exactly what i will do.
Waiting for a couple of days to find a good deal for the 4TB disks, until then will give some rest to the server.. been up 24/7 for last 4 months. smile.gif

I have seen a bunch of reviews at various sites and I own both so I am fully away of the differences.

There is some small aspects that get overlooked- 7200rpm is vastly superior in seek times, random IOPS and just general stuff as compared to rather simplistic sequential reads and writes (all in a row).
I would not go as far as saying what you said wink.gif I think you are wrong.

It would be better said: The new Seagate 4TB drives are 5900rpm, and 1TB platters and hold a serious advantage over the traditional 5400rpm drives and are a much better blend of spindle speed, performance compromise

If your the type to naturally go for a 5400rpm drive it's probably better to go with a 5900rpm seagate because they use even less power than a WD RED or GREEN, and are much faster, and also cost less.

But the 3TB 7200rpm (and 2TB and 1TB 7200.14's) are operating in a performance territory that a 5900RPM 4TB can't go. 200MB/sec + speeds on the faster parts of the spindle, and average speeds a good deal higher than 4TB drives, not to mention superior in the random stuff and seek times that the faster 7200rpm spin allows for. I own and use both and there is a small difference that might not be that important to many in a simple server environments- but nonetheless there is still a difference.

My general findings are that while benchmarks are often a good measuring stick, the ideal results from the benchmark very rarely translate into real world performance. So if your seeing 160MB/sec speeds in a new drive on a fresh bench- your probably not going to see that consistently in the real world. That's my objection with 5400rpm- is that when they slow down and fill up in the real world they become slow dogs. I don't actually need the 200MB/sec speed of a 3TB Seagate 7200rpm drive, but what I appreciate is that in the worst possible case scenario it remains faster than my LAN and doesn't create a bottle neck. Do to this- you must only remain above 125MB/sec worst case scenario.

I have yet to find any drives that can do this as well for the same cost per TB as the 3TB Seagate 7200.14- and that's why I use them. If something can do it as well, and it is cheaper I would switch. The 4TB is close, but no cigar. Almost only counts in horseshoes or grenades. biggrin.gif

I just flashed a Dell H310 with LSI phase 16 IT firmware.

The funny thing is Windows doesn't pick it up as a 2008 Falcon like it does with a M1015. It is being reported as a Dell 6Gbps. I might trying to reprogram the SAS address to one of a M1015 tomorrow. Because the one on the Dell doesn't start with 500605b0

Good to know. Did you use sas2flsh or the Dell utility?

I picked up the card for $50. I don't even need one, I just wanted to try it It was a a bit more complex than flashing a M1015. First off, my trusty computer that I use for flashing won't boot up with the H310. I had to block 2 pins on the PCIe to boot up. Boots up fine on the other computers, but I didn't want to mess with Uefi.

Three step process.

Flash Dell 6Gbps IT with LSI sasflsh (I would have to go back and check what version I used)
Flash LSI P07 IT
Flash P16 IT

I will stick with IBM biggrin.gif
post #1226 of 3346
The Dell 6Gbps HBA firmware is just a repackaged version of the LSI P16 IT firmware. When you have the newest Dell 6Gbps HBA firmware flashed you can go into the setup and even see all the version info is the same as the LSI firmware. So you could have stopped at step 1 and had the same result as step 3.

I've often been able to find H200 or H310's for $50 sometimes even less. The cheapest I've found a M1015 recently was $84....

Agreed.

It was more of a curiosity killed the cat thing, I wanted to know if it could be done. Really even updating to P16 I find unnecessary. I believe the only thing they changed was copyright dates. Running Windows you don't even need IT mode, you can use IR mode

Another reason I wanted to play with the H310, I got it for $50. The word is out on the M1015's.
