Buying Recommendations / Re: AOC-SAS2LP-MV8 and Windows Powering down HDDs
« on: December 19, 2017, 10:23:19 am »
Just so anyone else has this issue, I know I'm bringing back a zombie but there are still folks like me who are still buying these cards SAS2LP-MV8 and having issues.


The only solution that will allow native windows spin down is to install the windows XP/2003 miniport driver instead. This will allow native spin down to work.

Thankfully, with the miniport driver, things work in windows7/8/server 2012 so it should function for years to come. Performance deltas are unknown as of now but I have read that performance is not degraded.

Oh and don't bother contacting supermicro support. It will be a waste of your time.

Hope this helps.


The zombie just won't die.  Can you tell me the name, version, and date of the miniport driver that works? I was able to find, 3/1/2010, mv94xx.sys, but that doesn't appear to allow drive standby.

That's what I thought so it's recreating overnight. I guess I could take another crack at 2.1 if email gets fixed. I don't know though, 2.0 is very stable for me and has saved me a couple of times already.

RAID-F Bug Reports / I regret ever having upgraded from RAID-F 2.0 to 2.1
« on: September 20, 2015, 07:35:22 pm »
RAID-F 2.0 was working great.  All scheduled jobs ran, I was able to restore deleted files, update, validate and quick-validate ran without problems.

Installed 2.1, had to recreate email and schedules and now email doesn't work and validate reports corrupted files, memory leaks, weirdness with file name displays, and my 9 hour weekly overnight validate locked up my system partway through.

So, I uninstalled 2.1 and put 2.0 back.  Now I can't get anything to run, it keeps reporting :

OK, let me do a bare metal restore of my boot drive from just before I upgraded to 2.1.  Should be exactly like I had never installed 2.1, but nope,  no luck, still getting java.lang.NullPointerException.

Looks like I'll have to recreate from scratch. This is an entire day wasted.

After upgrading to 2.1 from 2.0, re-entering my schedules and email settings, I find email notifications are no longer working. The Verify button on email settings works; I do get the test message, but FlexRAID no longer sends mail when a scheduled event completes.  No indication it tries to send email in the log file. Create Alerts On Success and On Failure are checked, but When Scheduled Only is not.

Also the log file has an odd device display for new files found and files that no longer exist:

During an Update:
[2015-09-18 08:05:36,515] WARN : D:0:0\<directory>\<file> no longer exist! Skipping...

During a quick validate:
[2015-09-18 08:00:04,559] WARN : Deleted: D:5:0\<directory>\<file>

Record any schedules you have set up. Also any email settings. You have to uninstall the current version first before installing the new one, and those settings will be lost. There's probably other settings not saved, but those were the only ones I'd changed.

Just wish I had written down my complicated RAID-F quick-validate/validate/update schedule before upgrading. Now I have to recreate it from memory.

RAID-F on Windows / Re: media problem
« on: April 09, 2015, 10:11:01 pm »
File metadata cannot be read from a flexraid pool volume.  Therefore no media files are indexed and you cannot search for them using Windows File Search. None of the media files will show up if you are using Windows as a media server either.

If all that's stopping your from re-installing FlexRAid is the installer sees the FlexRAID service as already installed, why not delete the service ? Download Autoruns (, got to the Services tab, find the FlexRAID service, and delete it.  The try the install again.

Snapshot RAID / Some files always show as changed, even after update
« on: October 28, 2014, 12:42:21 am »
Running 2.0 final [2014-08-16] [Snapshot 1.4 stable / Storage Pool 1.0 stable / Real-Time 1.0 experimental] in Snapshot mode on Windows Server 2012 Essentials R2.

I download photos from my camera into folders in a DRU on the server.  I then run a FleXRAID SNAPSHOT update to update the parity disk.  A quick validate after shows everything to be healthy and up to date.

I then geotag my photos which of course modifies them.  The geotag program preserves the file date and time of the photos. I then run an update and FlexRaid reports however many files were geotagged as changed as expected.  I then run a quick validate and all of the geotagged photos STILL show up as changed. No matter how many times I run an update after geotagging the photos, they still show up as changed during a quick validate.

The only way to fix this is to rename all the folders the geotagged files are in, run an update, rename them back again, and then do another update.  Oddly enough the second update shows nothing has changed.

I presume this behavior comes from the geotagging program preserving the file dates and times of the photos, but can't figure out how come quick validate still shows them as changed even after an update.  I've run into this behavior with corrupted dates on files where the date is far in the future, but the dates all seem normal with the geotagged photos.

General Discussion / A FlexRAID success story!
« on: January 29, 2014, 12:16:43 pm »
 ;D I thought it might be a good idea to relate how, with the help of some forensic data recovery software and FlexRAID, I was able to restore 4 failed DRU's back to bit perfect condition.  Thank you Brahim!

I have a 9 DRU, 1 PPU snapshot FlexRAID setup on a Windows Server 2012 Essentials system  The DRU's are all basically just the ServerFolders directory tree on individual 3 TB drives, and contain all my videos, pictures, music, documents, plus downloaded TV shows and movies.  I also have a large external drive that I use for backup.  Since I can't backup that huge amount of data, only my videos, music, and pictures are backed up.  5 of the drives are formatted ReFS as well as the backup drive; the rest are NTFS. A RAID snapshot update is performed every morning just after a quick validate, and a full validate is done every Sunday.

Last weekend I wanted to start on moving to Windows Server 2012 Essentials R2, so I shut down my system, swapped the boot SSD drive for a spare one, and installed R2 on it.  At some point during my install my system hung so I hit the reset button.  But the install completed and everything appeared normal until I put the original SSD back and booted up WS2012E again.  To my horror the system came back up with the 4 of the 5 ReFS drives corrupted, including my backup drive. Trying to open any of the corrupted drives brought up the message "X:\ is not accessible. The volume repair was not successful." No CHKDSK for ReFS drives as they are supposed to be self-repairing and more reliable than NTFS formatted drives. Yeah, right. Great, I thought, the backup drive is gone and I have more DRU's gone than I have PPU's.  All my irreplaceable videos, pictures, and music lost.

However, I am happy to say that after over a week of recovery efforts, everything is back!

The first thing to do was to stop all scheduled FlexRAID jobs and try to salvage as much as I could off of the corrupted drives using partition recovery software.  There are only a few software products supporting ReFS: ReclaiMe, REMO Recover, and R-Tools Data Recovery are the ones I found.  I used R-Tools to scan and copy as much as I could from each of the corrupted drives to a spare 3TB drive, format the corrupted ReFS drive as NTFS, and copy the recovered files back.  This had to be done individually for each of the 5 drives and took days, as the drives were quite full and the two copy operations sometimes took 20 hours to complete. I even managed to recover most of the backup drive files and used that to restore missing files that could not be copied from the corrupt drives.

Next step was to run a full FlexRAID validate.  This pointed out changed files, corrupt files, deleted files, and new files on the reconstructed DRU's.  There were plenty, as not all of the salvaged files were intact and some files that had been deleted months ago were retrieved from the corrupted drives. I deleted all the new and corrupt files and, for each DRU, moved the changed files to another drive just in case they could not be recovered, and ran a FlexRAID recover on the DRU.  The FlexRAID log was filled with thousands of "performing checksum" messages on the existing files, I assume because the original file dates had not been recovered intact.  However, FlexRAID recovered all the missing files on each DRU even with missing files on the other DRU's!  It took about 8 or 9 hours for each DRU, but all the deleted files were brought back intact.

I ran a final validate: no changes or bitrot detected.  The last step was a full verify: every bit verified correctly.

I am very happy with this result. Money well spent on FlexRAID.

A word of warning though: do not trust your data to ReFS formatted drives.  I don't know what happened to cause the corruption, but I have never had that kind of catastrophic failure with NTFS formatted partitions.

I believe your issue may be the same as the one I reported, as Windows 8 and Windows Server 2012 Essentials are similar:  File metadata cannot be read from a flexraid pool volume.  Therefore no media files are indexed and you cannot search for them using Windows File Search. None of the media files will show up if you are using Windows as a media server either.

That worked, thanks.  I did uninstall 11 before installing 11a but there must have been something left over.

RAID-F Bug Reports / Email notifications failing after 2.0u11a install
« on: April 03, 2013, 02:41:12 pm »
Ever since I installed the 11a release, email notifications have been failing. I have Java 7u17 32-bit installed on WS2012E.

That sounds like a good idea.  Thanks for the suggestion; I'll try that out.

Thanks for that info.  Looks like I'm out of luck then for using pooling and indexing together; I was hoping a Windows 8 driver would fix that problem.  Fortunately I only have a couple of folders that will not fit on a single drive, so I will dispense with pooling, go back to regular FlexRAID snapshot RAID, split the folders across a couple of drives, and manage the usage myself.
