General Discussion / Re: Best shceduled jobs configuration for tRaid
« on: August 14, 2017, 01:43:40 pm »
Just switched to windows 10 and traid for my server. What is best configuration for scheduled jobs?
Verify Sync

Use it only for troubleshooting. It stops at the first error.

Use first setting up the RAID to verify initial integrity and then monthly or so to verify RAID integrity.

Verify Sync
Same as above to blindly keep the parity data up to date.

Verify+ and Verify & Sync scan the entire array and collect data on blocks that are out of sync. Later, using the Forensic plugin, you can analyze for what data is affected. In the case of Verify+, you have the option to decide whether to recover or override the parity. With Verify & Sync, the parity is automatically updated and there is nothing else to do than being aware of what data was potentially affected.

So, choosing between Verify+ and Verify & Sync is mostly a user preference depending on how they want to deal with the upkeep of the array.

Any news on the preview or final?

Still no ETA. Nonetheless, this would be the first thing to be pushed out.
There have certainly been long delays, but the hope is to have things resume this Fall.

Brahim couldn't you specify here or in a wiki what you see as a stable system so we know. But yes I am with you that a UPS has to be there.
There should be no interpretation for what a stable system is. If a system is showing anomalies under load, then it is not stable.

The usual suspects are:
1. Inadequate power supply
2. Driver issues
3. Overloaded systems (controllers overheating and flaking under load)
4. Other software

In almost every case, there will be entries in the OS system logs.

I remember the days when running PC burn-in tests was the norm on DIY builds. Heck, even off the shelf builds were tested for stress and load.
It seems like these days people just run CPU tests and call it a day.

FlexRAID products are I/O intensive. So, tests that take into account I/O loads are important.

In all cases, the best test is the FlexRAID product itself. RAID creating, validation, and or verification must succeed without system issues.
If these fail with system errors, then the system is not stable for the purpose.

As far as RAID with SSD caching enabled, no system being used as a desktop is suitable. A headless system running with minimal other software is more appropriate.

Screenshots of your configuration as well as what you are seeing would go a long way.

Are we going to see this in the next release, and any indication of when that might be?  I was hoping to utilize this feature.
This will not be enable in the next release yet. The most likely case would be end of the year.
This feature also requires a fairly stable system on a good UPS. So, I am not too sure on whether I want to release to feature at all since many people concept of "stable system" seems to stretch quite a bit.

It could be driver or the SATA controller on the mobo being bad or flaking under load.

Check the NTFS permissions.
The service broker logs might also have entries on the specific of what's going on. So, look there and post those log entries.

Okay.  ::)

Hey, your issues have nothing to do with bad sectors. What matters here is that the requirements to run tRAID is a stable system.

Nothing is showing (links are broken).

Thank you for your reply

1) Im not sure what info you are requesting, it is a snapshot raid with 5 DRU's and 1 PPU
Screenshots of your configuration.

This is a known issue and it is fixed for the next release.

That is why I am using a RAID. If all of my storage hardware was perfect I wouldn't need redundancy.  ...

You are terribly confused. No RAID on earth will fix your hardware issues. The very foundation of a good RAID system is stable hardware. RAID is solely for the eventual disk failure.

1. Details of your configuration would be appropriate.

2. Can you please also provide a screenshot of the following folder (C:\FlexRAID-Managed-Pool\class1_0\)?

3. If there is any unmounted folder in C:\FlexRAID-Managed-Pool\class1_0\, could you please provide a screenshot of the content of that folder? This is to check whether that unmounted folder contains any file.

When configuring for SMART, checking the option to skip the disk if in sleep mode could have the side effect of disks going unchecked for a long time.

No, I never did.  I had to use the new license.  Just forgot to respond to this.
You mean you did not like the response provided and therefore there was no support?  ::)

If you upgrade your system often including all the drives in it, then sure, you won't like having to buy a new license for that completely new system. However, our license policy is fair in that it rewards those that maintain stable configurations and pushes the cost to those that have new hardware too often. New hardware often goes with new OS, new drivers, and new issues.

Further, it is just not common for someone to upgrade everything including drives too often. If you are in the unique situation where this is happening, then sure, you are a unique case. There has been talks for user licenses instead of system licenses, but the issue at hand was the cost of that user license as it would be more expensive.

If your OS is not seeing it as a physical disk, neither will FlexRAID.
It is likely that the driver for it emulates its disk representation. Emulated disks will not scan as physical disks.
