Let me preface by stating I do not have a lot of experience running raids. This is the first file server I setup and have been sharing with a bunch of room mates. The file server has been running pretty well for the past 2years. I?ve got an Areca card with 8 320gb Seagate drives on it as the main storage array. I?ve got a 2nd raid array that is the boot drive for the system running off the Intel motherboard controller.
Lately I?ve been having some issues with data corruption that requires me to run checkdisk to fix. This is a pain because I have to unmount the drive during off hours and some files seem to get lost during the ?fix?. These errors occur in random directories, some of which are inactive and some which are actively being worked on. All errors are occurring on the Areca array. No errors are occurring on the Intel array.
I?m wondering what the best course of action to take on this is. I?ve contacted Areca and they say that there may be drive errors or that my system memory is bad. I don?t think it?s the system memory because the Intel array is still running fine. This leads me back to either a bad card or a bad drive somewhere. Right now I am in the process of transferring all my data over to a 2nd storage solution so it will remain available to all users.
Onto the actual questions:
I?m taking Areca?s word on their card being good so I?d like to start from the drive side. First, I?m looking for help on how I can check the drives individually. I?ve run through some diagnostics on Arecas software and it all reports the drives being healthy. Should I just start sending these drives back to Seagate?
Second, what is the best way to trouble shoot this. I?m thinking either rebuild the array with current available drives or replace all the drives. If I rebuild my drive array, is there a simple way to perform a lot of red/writes to verify that data is being written properly? If I replace all the drives I can probably get away with half the drives since the drives are getting pretty cheap but again, how to I make sure this solution will work?
Or should I just take it down and send my card in for a check up.
Thanks for any help in advance. I?m really looking to take some action on this issue soon.
