<font size=3>Thanks for the responses. Here are the data listings
requested. <br><br>
I had LVM2 overlayed on a 6 x 200GB RAID5 disk array. As of now the
dev/VolGroup05/LogVol05 which is linked to /opt/bigdisk seems to have
vanished. It seems that the 6th drive (/dev/hdi) has dissappeared
from the RAID5 array. <br><br>
Any help would be most appreciated. <br><br>

<blockquote type=cite class=cite cite="">A 1TB volume storing 600GB of

XFS file system and was running on top of a six disk (each disk being
200GB) 1TB RAID5 array. On boot, the volume does not exist and the
RAID5 array is running with 5 out 6 drives. The 6th drive is
visible but not formatted. In the past, when you have 5 out 6
drives working, data integrity was maintained. In this case,
however, the volume just disappeared. Any ideas on how to
recover my volume and its 600GB of data?<br><br>
