Hi, I'm hoping you can help me with a 4100 that is reporting a fsck fatal error 39. It has 100gb drives in it. I've read a lot of the info here on the forum, but haven't found what I need. The four disks are in a RAID5 array. When I do disk check, I get fsck fatal error and several partially allocated inode errors. In my opinion one of the drives is probably failing, but my problem is I don't know how to find out which one. All the log says is that the errors are on disk 60000. None of the LEDs on the unit are showing amber for a failed drive. This snap unit has been in operation for a few years with no problems.
This is the second unit I've had with this exact problem. On the first unit that failed, I had previously replaced a bad drive (which did show an amber LED) and it ran fine for about a year, then the fsck fatal error and so on.
I'd sure like to get these units fixed. I have a fairly recent copy of the data backed up, so it is not too critical to worry about it, though I'd like to save it if possible.
So I guess my main question is how to determine which disk in the array is failing (hopefully it is just one). I have checked the server log and it doesn't show any info for any drives having problems except 60000. I have run "in dev" from the debug command line, and it isn't helpful other than showing that the RAID5 array is unmounted. I am fairly familiar with the snap 4100, but I don't know much of anything about DD, and I don't have spinrite or a unix system. Any help/advice is truly appreciated.
