At a loss...

[RobbieH]

Don't know what to do, or what the issue is. I have a problem with DrivePool that I can't figure out. My drives have gotten extremely slow, and I believe it has something to do with DP, or at minimum an issue with one of my drives. 

 

Since I thought the issue is related to DP, I uninstalled V1 and installed V2. It took forever for it to allow me to create the pool, and as of this minute, DP will not even open. 

 

If I click on Explorer to view my drives, the green bar at the top CRAWLS across as it is thinking, and then eventually I see no drive space estimate for the drive pool J:

If  you wonder why the one drive is called "Rormatted", it was so I could keep track with which of the Samsung/Seagate drives I had run chkdsk /f /B and then formatted. I did complete them both, and everything was going fine until yesterday.

 

Everything on the PC is at a snail's pace, even though the processor is sitting at 0-1%, with an occasional 3%.

The drive finally displayed, and I was able to get the DrivePool console up. It seems to be stuck on "Measuring..."

[RobbieH]

Well, I think I'm getting somewhere. I pulled half the drives out and the issue has gone away. I still don't know if this is hardware or software issues, but I'm starting to lean toward hardware.

[RobbieH]

That drive that says "reformatted" is dying on me. That's what is causing the issue. SeaTools says the drive has failed and should be replaced. The drive is out of warranty, so I guess I'm buying some WD Red drives sooner than I thought.

[britgeezer]

Yes its a hard way to find out.  I have been gradually replacing Greens with Reds.

I have a 2.5 inch WD red 1TB that's pretty stable and a 3.5 inch 6 TB on the way... so far I like them

Robbie,

 

First, I'm sorry to hear about the apparent drive failure/dying, as that is never a pleasant experience.

 

From what you describe, it definitely sounds like one of the drives may be dying.

However, if possible, check it's connection (make sure it's not a loose connection). And swap out the cable if you have a spare (make sure it's not just a bad cable that's causing the issues).

 

 

The drive is out of warranty, so I guess I'm buying some WD Red drives sooner than I thought.

Well, that really does suck.

However, getting some NAS drives is always good.  

[RobbieH]

The drive did die. It hangs on sectors that it can't read, which was causing all sorts of problems. There's a 5TB Red in there now.

[Christopher (Drashna)]

Well, I'm sorry to hear that it definitely did die. At least you got it replaced with a very nice drive!

[RobbieH]

Yeah and lost the second one of those 2TB Seagates yesterday, that's why I was asking in the other post about how to migrate off. Oh well, that's why we have DrivePool.

[Christopher (Drashna)]

Ouch, I'm sorry to hear that!

 

As for migrating off... I personally use the "Disk Usage Limiter" balancer, uncheck both duplicated and unduplicated options and let DrivePool clear out the drive. Then remove it.

I just got my 15TB pool running sweet.. I was restoring a backup rom and old 300gb Maxtor IDE HDD in a USB 2.0 external case my pool is 2 6TB WD red drives 1 WD 1TB green sata 2 3gb/s and a 1 TB wd Black sata 3 6gb /s and 1 1TB 2.5 wd red 6gb/s. and I got 35-40MB/s from the usb 2 to the pool.. 260gb transferred in under 2Hours.

[Ryo]

my point was that the reds are fast as hell in a pool

[Christopher (Drashna)]

Ah, okay.

 

And yeah, the REDs (and Seagate NAS drives) are very fast. So they're great for a pool.

Are you also running Scanner?  I have DP running on both machines, with Scanner on both machines as well. Makes me feel safer anyway.

[RobbieH]

Oh yes, scanner was warning me that my drives were failing.
