Snapshot RAID / Re: does resume work yet?
« on: December 04, 2014, 09:28:56 am »
I have no problem with my system stability using Snapraid. Maybe Flexraid requires a more stable system. Again, I am happy with Snapraid for parity stuff, but there is no integrated pooling feature.

Can you explain to me exactly what buttons to press during the Create process of generating the initial parity data? The last time I tested this I had no time to troubleshoot, but I have time now. The last time I tried absolutely everything I could think of. Every variation. And every single time I rebooted and tried to resume the Create the process started right from the beginning again. I was pulling out my hair in frustration. This was almost exactly a year ago. So I assume there is a new version now. I don't mind testing again, but I need to know exactly what you are claiming will allow me to resume. Because it did not work for me last time I tested it. Maybe there is some obscure intermittent bug that only arises in my system that I can help you squash.

Snapshot RAID / does resume work yet?
« on: December 04, 2014, 12:40:23 am »
I've had to settle on using Snapraid for now because I cannot seem to resume a partial Create process. Snapraid's resume works perfectly for me and I can even control how often the state is saved to resume. I can reboot nearly as often as I want during Create without losing much parity creation time.

So why am I here if another application suits my needs? Because I now want a software pool (JBOD) function and it seems that Flexraid may have the best one available currently. So once again I am left considering a purchase of the full Flexraid product. If I am going to use what used to be called Flexraid View then it would be nice if I could use a fully compatible parity system as well.

So has anything changed in the past year since I last tested the software? Can I reboot and resume a partial create process and if so how much parity creation time will I lose? If I let Create run for 30 minutes and then Abort and reboot will I have to start over from the beginning or will I have 30 minutes worth of parity data already there?

Actually I did abort and try to resume without success. I guess this might be more of a bug report then. Sorry about that. I just assumed the feature wasn't there. I reformated all the parity drives since the last failed attempt. I will try to resume once again and report back. I think maybe the first time I paused and then aborted. This time I went directly to abort. Maybe that will make a difference.

To avoid confusion the task I was aborting was Create. I assume that's what you mean by initialization. Create, Abort, Resume Failed Create. That's the sequence I have been attempting without success so far. I don't have a problem with the 50 hour time period. As you say it is a one time cost. It's not something you have to do very often. It's still difficult though particularly if you cannot interrupt the process for a reboot without starting from the beginning again.

Unlike Snapraid, Flexraid doesn't seem to have a resume feature. Pause doesn't survive reboots. So it's of limited value. I have to leave my machine running in a single OS for at least 50 hours to create a snapshot. That isn't easy to do. I find myself having to build a second computer to actually use while Flexraid works undisturbed. This is less than ideal and Snapraid is clearly superior in this regard. So why be second best? Please implement a robust resume feature as soon as possible. I cannot think of any function that is more important for software like this.

General Discussion / Re: resume failed create but it just says "running"

Ruh roh. After "running" for a while the whole window just closed down. I mean the small window with the name of the configuration in the title bar. That just disappeared on its own. I'm just guessing here but it looks like "running" status doesn't mean anything is really happening. If this software had any real documentation maybe I would know whether re-Create will just overwrite all existing parity data or not. "Resume Failed Create" clearly isn't doing what I thought it would.

General Discussion / resume failed create but it just says "running"
« on: November 18, 2013, 04:49:14 pm »
I was about 26 hours into a 50 hour estimated create and I had to reboot. So I used "abort" and then when it finished I rebooted and then hit "resume failed create". The gui just says "running" with no other feedback as to whether anything is actually going on. "Create", "Resume Failed Create", and "Re-Create" buttons all seem to be pressable. Is this what is supposed to happen? Is my create being resumed from somewhere around 26 hours in? Is there any way I can check to see if anything is actually happening?

General Discussion / Re: Parity Calculation Performance
« on: November 17, 2013, 06:29:01 pm »
I agree that 5 PPUs is overkill. I don't really expect to have 5 drives die simultaneously under normal conditions. In my case however this parity backup is for taking my drives with me on a transpacific flight. Basically as a bunch of drives in a bag stuffed into an overhead bin. I've done this sort of thing before and none of the drives failed right away, but I had a series of drive failures within 6 months. For general usage I'd probably use no more than 2 parity drives. I've had quite a few drive failures in my life but I don't think I've ever had 2 drives fail within a day or two of each other. So 2 parity drives would probably be more than sufficient under normal circumstances.

So you've found that the number of PPUs doesn't affect performance? I'll have to do some of my own testing as well eventually. In my case it certainly doesn't appear that my old Core 2 Duo is much of a bottleneck since CPU time never exceeds 75%.

Well I have 10 DRUs and 5 PPUs and my parity calcs are running at 15.58 MB/s. The CPU is an E8600 core 2 duo overclocked to 4 Ghz. Motherboard is a DFI x48 Lanparty. The parity drives are 4 new 3TB 7200rpm Toshibas and a couple of old 1.5 TB 7200 RPM Seagates. CPU time seems to hover at around 65% varying a lot between 50 and 75. Flexraid seems to do pretty well with RAM usage only using about 300 MB or so. Looks like a parity backup will take about 2 full days on this system. I assume that it's the 5 PPUs that really slow things down.

I just downloaded the trial version of RAID-F and attempted to start a create process. At first I tried this with 10 DRUs and 3 PPUs. That seemed to work fine and I aborted at around 38%. Then I tried to add 2 more PPUs for a total of 5 PPUs, but this time when I pressed "Create" I get a license exception error. I'm quite ready to purchase a license, but first I'd like to see if flexraid will work for me.

edit: On the web client page I went into System Control Panel -> Reset Activation and then requested another trial license. That seems to have stopped the licensing exception error at least for now.

General Discussion / Re: one license for both windows and linux?

I'm sorry. I still don't understand. Why can't I just share the configuration files between the Linux and Windows installations?

I spend most of my time in Linux, but during a period when I am playing a computer game or using some windows-only application I can be running in Windows for weeks. So it really would be nice to be able to update the parity data from either OS. Is this really so difficult to implement?

In both linux and windows the only file systems with data that I want to protect are NTFS. I do have a couple of ext3 partitions, but I don't currently need to parity protect them.

So are you saying that I would in fact need two license keys in order to switch back and forth between linux and windows without having to 'migrate' the license each time?

I do plan to choose one OS to initially create the parity data, but then I would like to be able to update parity from either linux or windows. Would purchasing two licenses for a single computer allow me to do this?

I don't understand what you mean by " the RAID configuration will not carry into the other OS without a migration every time". Doesn't 'migration' just refer to your licensing scheme? If that is the case then wouldn't buying two licenses solve that problem? I wouldn't be happy about that of course, especially since this limitation would not have existed before you went commercial, but I would like to know.

I dual boot between windows and linux. I use linux most of the time, but also frequently boot into Windows XP or 7. Will I need to buy two licenses in order to run flexraid from both OSes on a single machine?

Snapshot RAID / How do I enable the flexraid recycle bin?
« on: February 01, 2013, 02:20:22 pm »
I cannot find any option for it in the web ui. I have disabled the windows recycle bin for all of my drives. I am using the windows version of snapshot raid in expert mode. I am not currently using drive pooling.

Storage Pooling / difficulty understanding explicit merge definitions
« on: February 01, 2013, 01:11:09 am »
I have read but I still don't understand how this mode works.

The first view you define has to be the root view (-driveLetter:\).
After you’ve defined the root view, you can then define its sub views.

What is a view? What is a root view? What is a sub view?

- specifies the containing folder (Ex: -K:\)
What do you mean by containing folder? Can you give an example?

|-* means, merge this path into the containing folder
What does it mean to merge a path? Can you give an example?

|-+ means add this path as an element of the containing folder
What does it mean to add a path? Can you give an example? What is an element of a folder? Can you give an example? What is the difference between merging a path and adding a path?

|-<…> defines a virtual folder (which is always a child of the containing folder)
A virtual folder only exists through FlexRAID-View and is used to virtually organize your data without cluttering your filesystem.

Huh? I thought all folders in a pool were virtual? What is the difference between a virtual folder and a path to a folder that is either added or merged? What is Flexraid-View and how else can non-virtual folders be viewed?

I started the create process, but 90 minutes in my computer shut itself down. It may have been a brief power failure. I rebooted and deleted the parity data and started a new create process. I didn't see any way to resume. Is there a way to resume a create if it was interrupted due to a power failure? The process looks like it will take about 24 hours. I'd hate to get 23 hours in and then not be able to resume if something goes wrong.
