Also, extent 0 is the beginning of the drive. This is the area of the drive where boot sectors, LVM tables, etc are placed. I would probably schedule a replacement real soon.

I have a HP 9000/871 running 11.00. Recently there have been numerous issues with a particlar a file system hanging(intermittent problem). Associated with this hang is the fact that fsck returns an error referencing an unreadable "extent 0 on primary OLT, and extent 1 on copy OLT". Also accompanying this error is the fact that vgchange, vgscan, vgdisplay all result in reference error to the particular lv(/dev/vg01/lv10 - vxfs). Presently I have access to the file system, and have successfully backed it up using tar -cvf to tape. Can anyone advise on what steps should follow(disk replacement,reformat and restore from tape etc...). Suggestions welcomed.
