Benefit of using punchdowns vs RJ45 Coupler? in c/[email protected]
[–] [email protected] 1 points 1 year ago

I measured the depth of the wall which is 4" Is it a safe bet to get a 0.5' patch cable to connect the two couplers? Or should I go with 1ft?

Load Cycle count increasing even though Head Parking is disabled in c/[email protected]
[–] [email protected] 1 points 1 year ago

I used to disable EPC and PowerBalance on my Seagate drives and observed the same behavior. After awhile of using Seachest to disable these functions, I decided to re-enable them.

Mostly because I see no need to have the head hovering over my media at all times. I have no reason to save power, but I made this decision based upon how uncommmon it actually is to disable EPC and PB. Aside from a half dozen tech articles and various online posts.

In order for the drive to even get close to the amount of cycles they are rated for, you'd have to be witnessing some extremely aggressive head parking. (Based on 600k cycles) To give you an idea my drives park about 25 times daily on avg. (I have 3 min S.M.A.R.T. check intervals)

In my opinion and apparently every drive manufactuerer's default setting it's a good idea to leave defauly settings in place unless you have a really good reason. Even coming from a 24/7 always on, never spin-down datahoarder like myself I favor the "protections" of having the head safely placed away from the media over disabling EPC and PB. But to each is own.

Populating HBA or MB SATA? in c/[email protected]
[–] [email protected] 1 points 1 year ago (1 children)

I've heard a few horror stories of LSI HBA's causing some serious data corruption. Most of these cases were due to insuffiencient airflow. When it comes to data integrity I wonder if LSI HBA's in IT mode have more or less ability to detect errors or increase/decrease the risk of data corruption?

Populating HBA or MB SATA? (alien.top)
 

I was wondering what your approach is to using available SATA ports for your array.

I have six MB SATA ports and eight SATA available via HBA (9211-8i)

Do you recommend populating all available motherboard SATA ports first, then using an HBA for the rest of the array? Is it better to have all of the data disks if possible on the HBA first as a priority?

Do you guys recommend keeping many disks as possible on the same controller? (i.e. populating HBA first)

What is your test method for new HDDs before adding to array? (alien.top)
 

I'm looking to add some large Enterprise HDD's to my array and was wondering if a Long Smart Test would be sufficient before putting the drive into service?

I use Windows/Snapraid and have/use HDD Sentinel and also could run Read and/or write tests.

I'm curious what others testing methods are after a drive is shipped to them before putting it into service?

Question regarding Snapraid recovery scenario (alien.top)
 

A Snapraid user has six data disks and two levels of parity.

If a second data drive dies during the "snapraid fix" operation for the first failed drive, will the fix for the first failed drive continue without issue?

If the fix for the first drive completes without issue should the user then perform another "snapraid fix" operation for the second failed drive?

Or should the first fix operation be cancelled and a fix operation started for both drives at the same time? ex: "snapraid -d d1 -d d2 -l fix.log fix"?

Similarly, if one of the two parity drives fails during a sync operation, will the second parity drive allow the operation to complete successfully without any interaction from the user?

Should I bite the bullet or wait until Black Friday? in c/[email protected]

If you didn't already buy, I HIGHLY recommend you go to serverpartdeals.com and get a manufacturer refurbished drive from them. Not only do they have the best most secure packaging for hard drives, but often the best deals and a truly excellent track record.

Snapraid "Smart" cannot see drives attached via HBA (alien.top)
 

My HDDs which are attached to motherboard SATA show up when running Snapraid Smart commands without issue.

However the two HDDs I have attached to my Dell Perc H310 HBA in IT mode don't report Smart results from Snapraid.

Smartctl only shows these two drives as SCSI devices when I do a "smartctl --scan" command.

But these drives that are attached via HBA don't appear when running "Snapraid smart"

Does anyone know how to get Snapraid to see the drives when running Snapraid smart command?

I'll be adding many more drives to my HBA soon, and would like to figure out this issue.
