[Preclear.sh results - Questions about your results? Post them here.]

The total process took 41 hours. I've compared the preclear report with others, to find that the 3rd part is actually twice as slow as the first two with others as well. Still would like to know why that is.

 

Anyway, for those interested, i've included the reports for this Hitachi HDS724040ALE640 4TB disk.

Is it normal that the post-read is twice as slow as the other parts? And what about preclear's speed indicator?

Is the process still working like it should or do i have some sort of problem?

Anyone?

Question about the preclear progress. This is my first build and first time i'm using preclear. I'm running unRAID v5.0 rc5, and i'm trying to preclear a brand new Hitach 4TB disk (HDS724040ALE640).

 

I know it's a lengthy process. I've watched the first 2 steps (pre-read & zeroing) which each took about 10 hours, with a speed varying from 150MB/s at start to about 95MB/s towards the end, which is pretty normal.

 

Now the process is doing it's final post-reading, and i would assume, since the pre-read and zeroing each took 10 hours (totalling 20 hours), this also would take about 10 hours.  But now, 10 hours later, it just passed 50% completion. The speed is pretty continue according to the script at about 120MB/s, which is odd, because with that speed things should be finished in 10 hours... see screenshot.

 

What baffles me even more is that unMenu's myMAIN progress shows a rate of about 55MB/s, which is in sync with the time it takes... but why is this taking twice the time it took the prereading/zeroing?

 

Is it normal that the post-read is twice as slow as the other parts? And what about preclear's speed indicator?

Is the process still working like it should or do i have some sort of problem?

[The Enclosure Thread]

I'm thinking about an unRaid setup, but since this will be placed in the mains utility cabinet, i don't have the space for a tower. There is also not enough depth for a 19" casing. What i'm looking for is a small form factor enclosure, which still can hold 8 to 12 disks, like e.g. the Synology 1812 or 2411:

 

 

Even a tower casing that can be placed on it's side would be ok, if it's depth doesn't exeed 40cm. But from what i can find, almost all tower enclosures have their on/off switch and controls on top, not on the front of the machine...

 

Any tips?
