After spending too many nights to 4am working to resolve this, it was really starting to get to me so I have decided to take a break until I get a chance to go back at it.
I have bough a couple more hard drives 1 2TB drive adn 1 1TB drive and then dd_rescued all the data that I could into images on those drives in the drives original state as the system went down. I also have 4 replacement 500GB drives that I have been restoring those images unto and trying different scenarios. I have only once been able to recreate the raid5 array and actually have the PVs visible. When trying to access though XFS complained that it could not find superblock or something along those lines so when running the XFS repair tools to make it "healthy" again I was able to see some of the directory structures on the volume as before but not the majority of it. Majority of the files showing up were not valid files either (ie jpg files that you could not view, etc).
So out of the 4 drives I should have the following currently:
sdb1 -> failed physically, I have already tried a head swap on it and got the same results (can not get more than about 100MBs of data off it until it quits.) I suspect there might be spindle damage to it as it seems to get a bit of a wobble when it runs with the cover off. I do not have any tools to attempt and perform a dual platter move to one of my other drives so until I do I am leaving this oen alone.
sdc1 -> imaged to a separate drive in its original state.
sdd1 -> imaged to a separate drive in its original state.
sde1 -> imaged on a separate drive in original state. In its original state however this drive got kicked out of the array first and its events are less than the other 3... I am hoping that somehow using this drive instead of sdb1 I will be able to recreate this array again and at least get some of my data back.
Not giving up yet, but it is looking really grim for me right now
If anyone has any other ideas, I'd love to hear them.
