Can't mount RAID 5 array


So here is the deal, I had a bad drive which I replaced and brought the RAID array back online, over night I let it run it's recovery and now the RAID array shows clean

Code:
[root@viamao ~]# mdadm --detail /dev/md0
/dev/md0:
        Version : 00.90.01
  Creation Time : Tue Aug  4 19:45:07 2009
     Raid Level : raid5
     Array Size : 5128021248 (4890.46 GiB 5251.09 GB)
    Device Size : 732574464 (698.64 GiB 750.16 GB)
   Raid Devices : 8
  Total Devices : 8
Preferred Minor : 0
    Persistence : Superblock is persistent

    Update Time : Wed Aug  5 08:51:01 2009
          State : clean
 Active Devices : 8
Working Devices : 8
 Failed Devices : 0
  Spare Devices : 0

         Layout : left-symmetric
     Chunk Size : 64K

    Number   Major   Minor   RaidDevice State
       0       8       48        0      active sync   /dev/sdd
       1       8       64        1      active sync   /dev/sde
       2       8       80        2      active sync   /dev/sdf
       3       8       96        3      active sync   /dev/sdg
       4       8      112        4      active sync   /dev/sdh
       5       8      128        5      active sync   /dev/sdi
       6       8      144        6      active sync   /dev/sdj
       7       8      160        7      active sync   /dev/sdk
           UUID : 6f408f1e:729fdd3c:ef86d4df:0e7e9b26
         Events : 0.3
Problem is, I can't mount the RAID array, and I fear that I have lost data.

[root@viamao archive1]# mount /dev/md0 /share/archive1
mount: you must specify the filesystem type

[root@viamao archive1]# mount -t ext3 /dev/md0 /share/archive1
mount: wrong fs type, bad option, bad superblock on /dev/md0,
or too many mounted file systems

Anything I can do at this point to see for sure if the file system is corrupt or if I have lost data? What a terrible way to start a Wednesday morning.
