General Discussion / Selective Validate/Verify???????
« on: October 24, 2014, 11:06:58 pm »
I have 6 DRUs in my pool,  drive letters :F though :K. I keep getting a Windows "Low Memory Warning" at 91% on both Validate and Verify.

Is it possible to run a "selective" Validate and or Verify on individual drives or groups of drives in the pool? What would be the process to do that if it's possible?

RAID-F on Windows / Flexraid Validate/Verify Low Memory Warning issues
« on: October 23, 2014, 09:42:13 pm »
I've been fighting with this issue for sometime now.

My system:
mobo: AsRock Z87 Extreme 4
cpu: Haswell i5
memory: 8GB DDR3 1600
OS: Win 7 64bit
Main drive: Samsung EVO 250GB SSD
Hard drives: DRU - 7 x 3TB Samsung, PPU - 1 x 4TB Samsung

First off, I am NO windows guru however, I can usually work through most problems. (If anything, I'm much stupider on PC's since I switched to all Mac years ago)

My Flexraid problem: Updates run fine, no issues. Validate and Verify will not complete and lock the system up. No matter what I do, the problem repeats itself EXACTLY, EVERY DAMN TIME!

Symptom: When I first run a Validate or Verify, everything runs fine (low system memory usage) until somewhere around of the 50 - 55% mark. At that point, modified memory starts replacing standby & free memory as the process runs. Just before either process clicks over to 92% (same point, every single time), modified has taken over almost all of the available memory and then it quickly spikes. Once that happens I get a "Low Memory Warning Error". Flexraids cpu usage spikes up and everything comes to a stand still. One time, i let it run like that for 17 hours and I think it moved to 93% complete, iirc.

I am not the only person with this exact same problem from doing a net search. I have tried everything I can think of. I have tried shutting down every program and process thats running (selectively and all at once) that is not needed and I still get the same issue. I've tried watching the process with RAMMAP and Process Explorer running and don't see anything damning happening to cause this. I can watch the system processes and see that large chunks of data (for example Bluray rips) are being moved to the Modified memory for processing.The issue seems to be caused by Flexraid moving this data to modified memory and then not releasing it after it is done with it.

I've reached the point where it's time to go a different direction if I can't get this solved as I have no way to Verify or Validate the long term health of my files. My preference of course would be to continue with Flexraid.

Any thoughts? Ideas? Questions?

I don't want to have to do a complete re-install and re-rip 650+ Blurays so that is not an option. Right now, I am considering a possible move to SnapRaid + Stablebit Drivepool. Again, I would much, much prefer to get this sorted out.......

General Discussion / No SMART data issue
« on: May 26, 2014, 07:31:49 pm »
I am having a weird problem with my current Flexraid .12c installation. I am having issues getting Flexraid to show SMART data.

My build: ASROCK Z87 Pro 4 Extreme mobo; 4 Intel SATA III and 2 Asmedia SATA III ports on mobo + 1 Asmedia 2 port SATA III PCI card; 6 3TB Seagate DRU's and 1 4TB Seagate PPU.

I can not get Flexraid to report SMART data (with one exception described below) on any of the on-board SATA ports used for the pool drives. Flexraid will however report the SMART data for the one drive that is plugged into the add-on Asmedia SATA card (uses same driver as on board Asmedia ports) and it will show the SMART data from the OS SSD drive. At first, I thought it was a mobo/drivers issue however, programs such as crystal Disk Info have no problems displaying the data. Also odd is my friend has the EXACT same setup as me and Flexraid displays his SMART data (We have compared bios settings, drivers, etc and our system settings are identical).

The one exception from above is my drive type setting in my bios. If I set my global drive type from SATA to RAID (even though I don't go through setting up the array) in the bios, Flexraid will show the SMART data. However, I really don't want to do this as I'm not sure if this could cause issues with Flexraid.

I have also tried, using info from some threads here and info from the wiki, setting my drive mapping up in Flexraid. When I do so, Flexraid will show some SMART data but it is incomplete (no temp, no stats, etc....). Best I can tell, the entered advanced mapping info is correct.

Honestly, I have played around with this so much it is starting to drive me nuts!

Any ideas?

General Discussion / Screwed up my pool somehow........
« on: May 07, 2014, 10:43:31 pm »
Well, somehow I hosed my Flexraid server..... Saturday night, finished watching an episode of a TV show (Plex server across Roku), went to watch the next episode and got an error message. Logged on to server and and checked the file and sure enough, corrupted. Checked the next episode in line.... corrupted! Long story short, almost all of my audio (.flac) albums are corrupted and upwards of 60% of my MKV files (movies and TV shows) are corrupted. Using MKVToolnix, it appears that the audio tracks of the .MKV files are gone! They can't be played and can't be fixed (tried a couple of solutions found on the net but nothing worked. All of the file sizes are unchanged.The system passed an update and validate Friday night so I ran a verify Sunday and it failed.

Thoughts:
1. At first I thought it was limited to my TV shows only. I use NZBdrone to handle/organize my TV shows. I initially thought that NZBdrone was somehow corrupting the files until I discovered that the issue included movies and music. Oddly, I have hundreds (if not thousands) of digital comics and not a single one was corrupted.....
2. From what I can find, there aren't any viruses that specifically attack MKV files. Malware scans, Anti-virus scans (including boot time scan) all come back clean. Windows Event Viewer doesn't show much that would have anything to do with this issue.
3. All drives in the pool appear healthy. I thought perhaps I had a drive going bad but, the corrupted files are across the whole pool. I did add a new drive and 2 port SATA card to the pool the day before the crash but, everything seemed OK and was working fine.
4. I am sick and at a complete loss......

At this point, I plan on scrubbing the ENTIRE system back to step one. Format the SSD, re-install window & and software, re-run multiple malware/virus scan. Same for all the pool drives (6 x 3TB DRU + 1 x 4TB PPU). I'll then set Flexraid back up. Since I don't trust the files that appear untouched, nor do I feel like going through every MKV on my system to see which ones play, I won't be trying to save any of them. The thought of re-ripping 560 Blu Rays has me soooooo excited!!!!!

My pool has been rock solid for the 5 months I've had it running.... Any thoughts? Ideas on what I should or shouldn't do next time?

General Discussion / Windows recycle bin question
« on: January 25, 2014, 12:10:38 pm »
I installed Flexraid (RaidF with pooling) two days ago and followed a guide I found on the net. Before setting up the pool and initializing, I individually shutoff the recycle bin to each of the pool drives. Once the pool was setup, I enabled the Flexraid recycle feature by changing the setting to "true". The guide then instructed me to go back to Windows Recycle Bin properties (there was an accompanying picture that showed the V: drive in the recycle bin) and also set files to not be moved to the pool drive. I do not however see my V: drive in the recycle bin.

I've searched for the answer quite a bit here, on the net, and looked through some of the Flexraid changelogs and can't find a definitive answer as to whether the V: drive should be in the recycle bin. The closest I have come to an answer I found is where Brahim noted that Flexraid disables the recycle bin but, I'm not sure if his response was in the same context as my issue. Is it correct that the pool drive no longer shows in the recycle bin or, do I have some other problem?

Thanks, habe
